API extensions

The changes below were introduced to the Incus API after the 1.0 API was finalized.

They are all backward compatible and can be detected by client tools by looking at the api_extensions field in GET /1.0.

storage_zfs_remove_snapshots

A storage.zfs_remove_snapshots daemon configuration key was introduced.

It’s a Boolean that defaults to false and that when set to true instructs Incus to remove any needed snapshot when attempting to restore another.

This is needed as ZFS will only let you restore the latest snapshot.

container_host_shutdown_timeout

A boot.host_shutdown_timeout container configuration key was introduced.

It’s an integer which indicates how long Incus should wait for the container to stop before killing it.

Its value is only used on clean Incus daemon shutdown. It defaults to 30s.

container_stop_priority

A boot.stop.priority container configuration key was introduced.

It’s an integer which indicates the priority of a container during shutdown.

Containers will shutdown starting with the highest priority level.

Containers with the same priority will shutdown in parallel. It defaults to 0.

container_syscall_filtering

A number of new syscalls related container configuration keys were introduced.

• security.syscalls.blacklist_default

• security.syscalls.blacklist_compat

• security.syscalls.blacklist

• security.syscalls.whitelist

See Instance configuration for how to use them.

auth_pki

This indicates support for PKI authentication mode.

In this mode, the client and server both must use certificates issued by the same PKI.

See Security for details.

container_last_used_at

A last_used_at field was added to the GET /1.0/containers/<name> endpoint.

It is a timestamp of the last time the container was started.

If a container has been created but not started yet, last_used_at field will be 1970-01-01T00:00:00Z

etag

Add support for the ETag header on all relevant endpoints.

This adds the following HTTP header on answers to GET:

• ETag (SHA-256 of user modifiable content)

And adds support for the following HTTP header on PUT requests:

• If-Match (ETag value retrieved through previous GET)

This makes it possible to GET an Incus object, modify it and PUT it without risking to hit a race condition where Incus or another client modified the object in the meantime.

patch

Add support for the HTTP PATCH method.

PATCH allows for partial update of an object in place of PUT.

usb_devices

Add support for USB hotplug.

https_allowed_credentials

To use Incus API with all Web Browsers (via SPAs) you must send credentials (certificate) with each XHR (in order for this to happen, you should set withCredentials=true flag to each XHR Request).

Some browsers like Firefox and Safari can’t accept server response without Access-Control-Allow-Credentials: true header. To ensure that the server will return a response with that header, set core.https_allowed_credentials=true.

image_compression_algorithm

This adds support for a compression_algorithm property when creating an image (POST /1.0/images).

Setting this property overrides the server default value (images.compression_algorithm).

directory_manipulation

This allows for creating and listing directories via the Incus API, and exports the file type via the X-Incus-type header, which can be either file or directory right now.

container_cpu_time

This adds support for retrieving CPU time for a running container.

storage_zfs_use_refquota

Introduces a new server property storage.zfs_use_refquota which instructs Incus to set the refquota property instead of quota when setting a size limit on a container. Incus will also then use usedbydataset in place of used when being queried about disk utilization.

This effectively controls whether disk usage by snapshots should be considered as part of the container’s disk space usage.

storage_lvm_mount_options

Adds a new storage.lvm_mount_options daemon configuration option which defaults to discard and allows the user to set addition mount options for the file system used by the LVM LV.

network

Network management API for Incus.

This includes:

• Addition of the managed property on /1.0/networks entries

• All the network configuration options (see Network configuration for details)

• POST /1.0/networks (see RESTful API for details)

• PUT /1.0/networks/<entry> (see RESTful API for details)

• PATCH /1.0/networks/<entry> (see RESTful API for details)

• DELETE /1.0/networks/<entry> (see RESTful API for details)

• ipv4.address property on nic type devices (when nictype is bridged)

• ipv6.address property on nic type devices (when nictype is bridged)

• security.mac_filtering property on nic type devices (when nictype is bridged)

profile_usedby

Adds a new used_by field to profile entries listing the containers that are using it.

container_push

When a container is created in push mode, the client serves as a proxy between the source and target server. This is useful in cases where the target server is behind a NAT or firewall and cannot directly communicate with the source server and operate in pull mode.

container_exec_recording

Introduces a new Boolean record-output, parameter to /1.0/containers/<name>/exec which when set to true and combined with with wait-for-websocket set to false, will record stdout and stderr to disk and make them available through the logs interface.

The URL to the recorded output is included in the operation metadata once the command is done running.

That output will expire similarly to other log files, typically after 48 hours.

certificate_update

Adds the following to the REST API:

• ETag header on GET of a certificate

• PUT of certificate entries

• PATCH of certificate entries

container_exec_signal_handling

Adds support /1.0/containers/<name>/exec for forwarding signals sent to the client to the processes executing in the container. Currently SIGTERM and SIGHUP are forwarded. Further signals that can be forwarded might be added later.

gpu_devices

Enables adding GPUs to a container.

container_image_properties

Introduces a new image configuration key space. Read-only, includes the properties of the parent image.

migration_progress

Transfer progress is now exported as part of the operation, on both sending and receiving ends. This shows up as a fs_progress attribute in the operation metadata.

id_map

Enables setting the security.idmap.isolated and security.idmap.isolated, security.idmap.size, and raw.id_map fields.

network_firewall_filtering

Add two new keys, ipv4.firewall and ipv6.firewall which if set to false will turn off the generation of iptables FORWARDING rules. NAT rules will still be added so long as the matching ipv4.nat or ipv6.nat key is set to true.

Rules necessary for dnsmasq to work (DHCP/DNS) will always be applied if dnsmasq is enabled on the bridge.

network_routes

Introduces ipv4.routes and ipv6.routes which allow routing additional subnets to an Incus bridge.

storage

Storage management API for Incus.

This includes:

• GET /1.0/storage-pools

• POST /1.0/storage-pools (see RESTful API for details)

• GET /1.0/storage-pools/<name> (see RESTful API for details)

• POST /1.0/storage-pools/<name> (see RESTful API for details)

• PUT /1.0/storage-pools/<name> (see RESTful API for details)

• PATCH /1.0/storage-pools/<name> (see RESTful API for details)

• DELETE /1.0/storage-pools/<name> (see RESTful API for details)

• GET /1.0/storage-pools/<name>/volumes (see RESTful API for details)

• GET /1.0/storage-pools/<name>/volumes/<volume_type> (see RESTful API for details)

• POST /1.0/storage-pools/<name>/volumes/<volume_type> (see RESTful API for details)

• GET /1.0/storage-pools/<pool>/volumes/<volume_type>/<name> (see RESTful API for details)

• POST /1.0/storage-pools/<pool>/volumes/<volume_type>/<name> (see RESTful API for details)

• PUT /1.0/storage-pools/<pool>/volumes/<volume_type>/<name> (see RESTful API for details)

• PATCH /1.0/storage-pools/<pool>/volumes/<volume_type>/<name> (see RESTful API for details)

• DELETE /1.0/storage-pools/<pool>/volumes/<volume_type>/<name> (see RESTful API for details)

• All storage configuration options (see Storage configuration for details)

file_delete

Implements DELETE in /1.0/containers/<name>/files

file_append

Implements the X-Incus-write header which can be one of overwrite or append.

network_dhcp_expiry

Introduces ipv4.dhcp.expiry and ipv6.dhcp.expiry allowing to set the DHCP lease expiry time.

storage_lvm_vg_rename

Introduces the ability to rename a volume group by setting storage.lvm.vg_name.

storage_lvm_thinpool_rename

Introduces the ability to rename a thin pool name by setting storage.thinpool_name.

network_vlan

This adds a new vlan property to macvlan network devices.

When set, this will instruct Incus to attach to the specified VLAN. Incus will look for an existing interface for that VLAN on the host. If one can’t be found it will create one itself and then use that as the macvlan parent.

image_create_aliases

Adds a new aliases field to POST /1.0/images allowing for aliases to be set at image creation/import time.

container_stateless_copy

This introduces a new live attribute in POST /1.0/containers/<name>. Setting it to false tells Incus not to attempt running state transfer.

container_only_migration

Introduces a new Boolean container_only attribute. When set to true only the container will be copied or moved.

storage_zfs_clone_copy

Introduces a new Boolean storage_zfs_clone_copy property for ZFS storage pools. When set to false copying a container will be done through zfs send and receive. This will make the target container independent of its source container thus avoiding the need to keep dependent snapshots in the ZFS pool around. However, this also entails less efficient storage usage for the affected pool. The default value for this property is true, i.e. space-efficient snapshots will be used unless explicitly set to false.

unix_device_rename

Introduces the ability to rename the unix-block/unix-char device inside container by setting path, and the source attribute is added to specify the device on host. If source is set without a path, we should assume that path will be the same as source. If path is set without source and major/minor isn’t set, we should assume that source will be the same as path. So at least one of them must be set.

storage_rsync_bwlimit

When rsync has to be invoked to transfer storage entities setting rsync.bwlimit places an upper limit on the amount of socket I/O allowed.

network_vxlan_interface

This introduces a new tunnel.NAME.interface option for networks.

This key control what host network interface is used for a VXLAN tunnel.

storage_btrfs_mount_options

This introduces the btrfs.mount_options property for Btrfs storage pools.

This key controls what mount options will be used for the Btrfs storage pool.

entity_description

This adds descriptions to entities like containers, snapshots, networks, storage pools and volumes.

image_force_refresh

This allows forcing a refresh for an existing image.

storage_lvm_lv_resizing

This introduces the ability to resize logical volumes by setting the size property in the containers root disk device.

id_map_base

This introduces a new security.idmap.base allowing the user to skip the map auto-selection process for isolated containers and specify what host UID/GID to use as the base.

file_symlinks

This adds support for transferring symlinks through the file API. X-Incus-type can now be symlink with the request content being the target path.

container_push_target

This adds the target field to POST /1.0/containers/<name> which can be used to have the source Incus host connect to the target during migration.

network_vlan_physical

Allows use of vlan property with physical network devices.

When set, this will instruct Incus to attach to the specified VLAN on the parent interface. Incus will look for an existing interface for that parent and VLAN on the host. If one can’t be found it will create one itself. Then, Incus will directly attach this interface to the container.

storage_images_delete

This enabled the storage API to delete storage volumes for images from a specific storage pool.

container_edit_metadata

This adds support for editing a container metadata.yaml and related templates via API, by accessing URLs under /1.0/containers/<name>/metadata. It can be used to edit a container before publishing an image from it.

container_snapshot_stateful_migration

This enables migrating stateful container snapshots to new containers.

storage_driver_ceph

This adds a Ceph storage driver.

storage_ceph_user_name

This adds the ability to specify the Ceph user.

instance_types

This adds the instance_type field to the container creation request. Its value is expanded to Incus resource limits.

storage_volatile_initial_source

This records the actual source passed to Incus during storage pool creation.

storage_ceph_force_osd_reuse

This introduces the ceph.osd.force_reuse property for the Ceph storage driver. When set to true Incus will reuse an OSD storage pool that is already in use by another Incus instance.

storage_block_filesystem_btrfs

This adds support for Btrfs as a storage volume file system, in addition to ext4 and xfs.

resources

This adds support for querying an Incus daemon for the system resources it has available.

kernel_limits

This adds support for setting process limits such as maximum number of open files for the container via nofile. The format is limits.kernel.[limit name].

storage_api_volume_rename

This adds support for renaming custom storage volumes.

network_sriov

This adds support for SR-IOV enabled network devices.

console

This adds support to interact with the container console device and console log.

restrict_dev_incus

A new security.guestapi container configuration key was introduced. The key controls whether the /dev/incus interface is made available to the container. If set to false, this effectively prevents the container from interacting with the Incus daemon.

migration_pre_copy

This adds support for optimized memory transfer during live migration.

infiniband

This adds support to use InfiniBand network devices.

dev_incus_events

This adds a WebSocket API to the /dev/incus socket.

When connecting to /1.0/events over the /dev/incus socket, you will now be getting a stream of events over WebSocket.

proxy

This adds a new proxy device type to containers, allowing forwarding of connections between the host and container.

network_dhcp_gateway

Introduces a new ipv4.dhcp.gateway network configuration key to set an alternate gateway.

file_get_symlink

This makes it possible to retrieve symlinks using the file API.

network_leases

Adds a new /1.0/networks/NAME/leases API endpoint to query the lease database on bridges which run an Incus-managed DHCP server.

The following existing endpoint has been modified:

• POST /1.0/containers accepts the new source type backup

dev_incus_images

Adds a security.guestapi.images configuration option for containers which controls the availability of a /1.0/images/FINGERPRINT/export API over /dev/incus. This can be used by a container running nested Incus to access raw images from the host.

container_local_cross_pool_handling

This enables copying or moving containers between storage pools on the same Incus instance.

proxy_unix

Add support for both Unix sockets and abstract Unix sockets in proxy devices. They can be used by specifying the address as unix:/path/to/unix.sock (normal socket) or unix:@/tmp/unix.sock (abstract socket).

Supported connections are now:

• TCP <-> TCP

• UNIX <-> UNIX

• TCP <-> UNIX

• UNIX <-> TCP

• UDP <-> UDP

• TCP <-> UDP

• UNIX <-> UDP

clustering_join

This makes GET /1.0/cluster return information about which storage pools and networks are required to be created by joining nodes and which node-specific configuration keys they are required to use when creating them. Likewise the PUT /1.0/cluster endpoint now accepts the same format to pass information about storage pools and networks to be automatically created before attempting to join a cluster.

proxy_tcp_udp_multi_port_handling

Adds support for forwarding traffic for multiple ports. Forwarding is allowed between a range of ports if the port range is equal for source and target (for example 1.2.3.4 0-1000 -> 5.6.7.8 1000-2000) and between a range of source ports and a single target port (for example 1.2.3.4 0-1000 -> 5.6.7.8 1000).

network_state

Adds support for retrieving a network’s state.

This adds the following new endpoint (see RESTful API for details):

• GET /1.0/networks/<name>/state

proxy_unix_dac_properties

This adds support for GID, UID, and mode properties for non-abstract Unix sockets.

container_protection_delete

Enables setting the security.protection.delete field which prevents containers from being deleted if set to true. Snapshots are not affected by this setting.

proxy_priv_drop

Adds security.uid and security.gid for the proxy devices, allowing privilege dropping and effectively changing the UID/GID used for connections to Unix sockets too.

pprof_http

This adds a new core.debug_address configuration option to start a debugging HTTP server.

That server currently includes a pprof API and replaces the old cpu-profile, memory-profile and print-goroutines debug options.

proxy_haproxy_protocol

Adds a proxy_protocol key to the proxy device which controls the use of the HAProxy PROXY protocol header.

network_hwaddr

Adds a bridge.hwaddr key to control the MAC address of the bridge.

proxy_nat

This adds optimized UDP/TCP proxying. If the configuration allows, proxying will be done via iptables instead of proxy devices.

network_nat_order

This introduces the ipv4.nat.order and ipv6.nat.order configuration keys for Incus bridges. Those keys control whether to put the Incus rules before or after any pre-existing rules in the chain.

container_full

This introduces a new recursion=2 mode for GET /1.0/containers which allows for the retrieval of all container structs, including the state, snapshots and backup structs.

This effectively allows for incus list to get all it needs in one query.

backup_compression

This introduces a new backups.compression_algorithm configuration key which allows configuration of backup compression.

nvidia_runtime_config

This introduces a few extra configuration keys when using nvidia.runtime and the libnvidia-container library. Those keys translate pretty much directly to the matching NVIDIA container environment variables:

• nvidia.driver.capabilities => NVIDIA_DRIVER_CAPABILITIES

• nvidia.require.cuda => NVIDIA_REQUIRE_CUDA

• nvidia.require.driver => NVIDIA_REQUIRE_DRIVER

storage_api_volume_snapshots

Add support for storage volume snapshots. They work like container snapshots, only for volumes.

This adds the following new endpoint (see RESTful API for details):

• GET /1.0/storage-pools/<pool>/volumes/<type>/<name>/snapshots

• POST /1.0/storage-pools/<pool>/volumes/<type>/<name>/snapshots

• GET /1.0/storage-pools/<pool>/volumes/<type>/<volume>/snapshots/<name>

• PUT /1.0/storage-pools/<pool>/volumes/<type>/<volume>/snapshots/<name>

• POST /1.0/storage-pools/<pool>/volumes/<type>/<volume>/snapshots/<name>

• DELETE /1.0/storage-pools/<pool>/volumes/<type>/<volume>/snapshots/<name>

storage_unmapped

Introduces a new security.unmapped Boolean on storage volumes.

Setting it to true will flush the current map on the volume and prevent any further idmap tracking and remapping on the volume.

This can be used to share data between isolated containers after attaching it to the container which requires write access.

projects

Add a new project API, supporting creation, update and deletion of projects.

Projects can hold containers, profiles or images at this point and let you get a separate view of your Incus resources by switching to it.

network_vxlan_ttl

This adds a new tunnel.NAME.ttl network configuration option which makes it possible to raise the TTL on VXLAN tunnels.

container_incremental_copy

This adds support for incremental container copy. When copying a container using the --refresh flag, only the missing or outdated files will be copied over. Should the target container not exist yet, a normal copy operation is performed.

usb_optional_vendorid

As the name implies, the vendorid field on USB devices attached to containers has now been made optional, allowing for all USB devices to be passed to a container (similar to what’s done for GPUs).

snapshot_scheduling

This adds support for snapshot scheduling. It introduces three new configuration keys: snapshots.schedule, snapshots.schedule.stopped, and snapshots.pattern. Snapshots can be created automatically up to every minute.

snapshots_schedule_aliases

Snapshot schedule can be configured by a comma-separated list of schedule aliases. Available aliases are <@hourly> <@daily> <@midnight> <@weekly> <@monthly> <@annually> <@yearly> <@startup> for instances, and <@hourly> <@daily> <@midnight> <@weekly> <@monthly> <@annually> <@yearly> for storage volumes.

container_copy_project

Introduces a project field to the container source JSON object, allowing for copy/move of containers between projects.

clustering_server_address

This adds support for configuring a server network address which differs from the REST API client network address. When bootstrapping a new cluster, clients can set the new cluster.https_address configuration key to specify the address of the initial server. When joining a new server, clients can set the core.https_address configuration key of the joining server to the REST API address the joining server should listen at, and set the server_address key in the PUT /1.0/cluster API to the address the joining server should use for clustering traffic (the value of server_address will be automatically copied to the cluster.https_address configuration key of the joining server).

clustering_image_replication

Enable image replication across the nodes in the cluster. A new cluster.images_minimal_replica configuration key was introduced can be used to specify to the minimal numbers of nodes for image replication.

container_protection_shift

Enables setting the security.protection.shift option which prevents containers from having their file system shifted.

snapshot_expiry

This adds support for snapshot expiration. The task is run minutely. The configuration option snapshots.expiry takes an expression in the form of 1M 2H 3d 4w 5m 6y (1 minute, 2 hours, 3 days, 4 weeks, 5 months, 6 years), however not all parts have to be used.

Snapshots which are then created will be given an expiry date based on the expression. This expiry date, defined by expires_at, can be manually edited using the API or incus config edit. Snapshots with a valid expiry date will be removed when the task in run. Expiry can be disabled by setting expires_at to an empty string or 0001-01-01T00:00:00Z (zero time). This is the default if snapshots.expiry is not set.

This adds the following new endpoint (see RESTful API for details):

• PUT /1.0/containers/<name>/snapshots/<name>

snapshot_expiry_creation

Adds expires_at to container creation, allowing for override of a snapshot’s expiry at creation time.

network_leases_location

Introduces a Location field in the leases list. This is used when querying a cluster to show what node a particular lease was found on.

resources_cpu_socket

Add Socket field to CPU resources in case we get out of order socket information.

resources_gpu

Add a new GPU struct to the server resources, listing all usable GPUs on the system.

resources_numa

Shows the NUMA node for all CPUs and GPUs.

kernel_features

Exposes the state of optional kernel features through the server environment.

id_map_current

This introduces a new internal volatile.idmap.current key which is used to track the current mapping for the container.

This effectively gives us:

• volatile.last_state.idmap => On-disk idmap

• volatile.idmap.current => Current kernel map

• volatile.idmap.next => Next on-disk idmap

This is required to implement environments where the on-disk map isn’t changed but the kernel map is (e.g. idmapped mounts).

event_location

Expose the location of the generation of API events.

storage_api_remote_volume_snapshots

This allows migrating storage volumes including their snapshots.

network_nat_address

This introduces the ipv4.nat.address and ipv6.nat.address configuration keys for Incus bridges. Those keys control the source address used for outbound traffic from the bridge.

container_nic_routes

This introduces the ipv4.routes and ipv6.routes properties on nic type devices. This allows adding static routes on host to container’s NIC.

cluster_internal_copy

This makes it possible to do a normal POST /1.0/containers to copy a container between cluster nodes with Incus internally detecting whether a migration is required.

seccomp_notify

If the kernel supports seccomp-based syscall interception Incus can be notified by a container that a registered syscall has been performed. Incus can then decide to trigger various actions.

lxc_features

This introduces the lxc_features section output from the incus info command via the GET /1.0 route. It outputs the result of checks for key features being present in the underlying LXC library.

container_nic_ipvlan

This introduces the ipvlan nic device type.

network_vlan_sriov

This introduces VLAN (vlan) and MAC filtering (security.mac_filtering) support for SR-IOV devices.

storage_cephfs

Add support for CephFS as a storage pool driver. This can only be used for custom volumes, images and containers should be on Ceph (RBD) instead.

container_nic_ipfilter

This introduces container IP filtering (security.ipv4_filtering and security.ipv6_filtering) support for bridged NIC devices.

resources_v2

Rework the resources API at /1.0/resources, especially:

• CPU

  • Fix reporting to track sockets, cores and threads

container_disk_shift

Adds the shift property on disk devices which controls the use of the idmapped mounts overlay.

storage_shifted

Introduces a new security.shifted Boolean on storage volumes.

Setting it to true will allow multiple isolated containers to attach the same storage volume while keeping the file system writable from all of them.

This makes use of idmapped mounts as an overlay file system.

resources_infiniband

Export InfiniBand character device information (issm, umad, uverb) as part of the resources API.

daemon_storage

This introduces two new configuration keys storage.images_volume and storage.backups_volume to allow for a storage volume on an existing pool be used for storing the daemon-wide images and backups artifacts.

This adds a new roles attribute to cluster entries, exposing a list of roles that the member serves in the cluster.

images_expiry

This allows for editing of the expiry date on images.

resources_network_firmware

Adds a FirmwareVersion field to network card entries.

backup_compression_algorithm

This adds support for a compression_algorithm property when creating a backup (POST /1.0/containers/<name>/backups).

Setting this property overrides the server default value (backups.compression_algorithm).

ceph_data_pool_name

This adds support for an optional argument (ceph.osd.data_pool_name) when creating storage pools using Ceph RBD, when this argument is used the pool will store it’s actual data in the pool specified with data_pool_name while keeping the metadata in the pool specified by pool_name.

container_syscall_intercept_mount

Adds the security.syscalls.intercept.mount, security.syscalls.intercept.mount.allowed, and security.syscalls.intercept.mount.shift configuration keys to control whether and how the mount system call will be intercepted by Incus and processed with elevated permissions.

Adds support for importing/exporting of images/backups using SquashFS file system format.

container_raw_mount

This adds support for passing in raw mount options for disk devices.

container_nic_routed

This introduces the routed nic device type.

container_syscall_intercept_mount_fuse

Adds the security.syscalls.intercept.mount.fuse key. It can be used to redirect file-system mounts to their fuse implementation. To this end, set e.g. security.syscalls.intercept.mount.fuse=ext4=fuse2fs.

clustering_sizing

Support specifying a custom values for database voters and standbys. The new cluster.max_voters and cluster.max_standby configuration keys were introduced to specify to the ideal number of database voter and standbys.

firewall_driver

Adds the Firewall property to the ServerEnvironment struct indicating the firewall driver being used.

storage_lvm_vg_force_reuse

Introduces the ability to create a storage pool from an existing non-empty volume group. This option should be used with care, as Incus can then not guarantee that volume name conflicts won’t occur with non-Incus created volumes in the same volume group. This could also potentially lead to Incus deleting a non-Incus volume should name conflicts occur.

container_syscall_intercept_hugetlbfs

When mount syscall interception is enabled and hugetlbfs is specified as an allowed file system type Incus will mount a separate hugetlbfs instance for the container with the UID and GID mount options set to the container’s root UID and GID. This ensures that processes in the container can use huge pages.

limits_hugepages

This allows to limit the number of huge pages a container can use through the hugetlb cgroup. This means the hugetlb cgroup needs to be available. Note, that limiting huge pages is recommended when intercepting the mount syscall for the hugetlbfs file system to avoid allowing the container to exhaust the host’s huge pages resources.

container_nic_routed_gateway

This introduces the ipv4.gateway and ipv6.gateway NIC configuration keys that can take a value of either auto or none. The default value for the key if unspecified is auto. This will cause the current behavior of a default gateway being added inside the container and the same gateway address being added to the host-side interface. If the value is set to none then no default gateway nor will the address be added to the host-side interface. This allows multiple routed NIC devices to be added to a container.

projects_restrictions

This introduces support for the restricted configuration key on project, which can prevent the use of security-sensitive features in a project.

custom_volume_snapshot_expiry

container_nic_routed_host_address

This introduces the ipv4.host_address and ipv6.host_address NIC configuration keys that can be used to control the host-side veth interface’s IP addresses. This can be useful when using multiple routed NICs at the same time and needing a predictable next-hop address to use.

This also alters the behavior of ipv4.gateway and ipv6.gateway NIC configuration keys. When they are set to auto the container will have its default gateway set to the value of ipv4.host_address or ipv6.host_address respectively.

The default values are:

ipv4.host_address: 169.254.0.1 ipv6.host_address: fe80::1

This is backward compatible with the previous default behavior.

container_nic_ipvlan_gateway

This introduces the ipv4.gateway and ipv6.gateway NIC configuration keys that can take a value of either auto or none. The default value for the key if unspecified is auto. This will cause the current behavior of a default gateway being added inside the container and the same gateway address being added to the host-side interface. If the value is set to none then no default gateway nor will the address be added to the host-side interface. This allows multiple IPVLAN NIC devices to be added to a container.

resources_usb_pci

This adds USB and PCI devices to the output of /1.0/resources.

resources_cpu_threads_numa

This indicates that the numa_node field is now recorded per-thread rather than per core as some hardware apparently puts threads in different NUMA domains.

container_nic_ipvlan_mode

This introduces the mode NIC configuration key that can be used to switch the ipvlan mode into either l2 or l3s. If not specified, the default value is l3s (which is the old behavior).

In l2 mode the ipv4.address and ipv6.address keys will accept addresses in either CIDR or singular formats. If singular format is used, the default subnet size is taken to be /24 and /64 for IPv4 and IPv6 respectively.

In l2 mode the ipv4.gateway and ipv6.gateway keys accept only a singular IP address.

This introduces the storage bucket API. It allows the management of S3 object storage buckets for storage pools.

storage_buckets_create_credentials

This updates the storage bucket API to return initial admin credentials at bucket creation time.

metrics_cpu_effective_total

This introduces a new incus_cpu_effective_total metric to the /1.0/metrics API. It reports the total number of effective CPUs.

projects_networks_restricted_access

Adds the restricted.networks.access project configuration key to indicate (as a comma-delimited list) which networks can be accessed inside the project. If not specified, all networks are accessible (assuming it is also allowed by the restricted.devices.nic setting, described below).

This also introduces a change whereby network access is controlled by the project’s restricted.devices.nic setting:

• If restricted.devices.nic is set to managed (the default if not specified), only managed networks are accessible.

• If restricted.devices.nic is set to allow, all networks are accessible (dependent on the restricted.networks.access setting).

• If restricted.devices.nic is set to block, no networks are accessible.

storage_buckets_local

This introduces the ability to use storage buckets on local storage pools by setting the new core.storage_buckets_address global configuration setting.

loki

This adds support for sending life cycle and logging events to a Loki server.

It adds the following global configuration keys:

• loki.api.ca_cert: CA certificate which can be used when sending events to the Loki server

• loki.api.url: URL to the Loki server (protocol, name or IP and port)

• loki.auth.username and loki.auth.password: Used if Loki is behind a reverse proxy with basic authentication enabled

• loki.labels: Comma-separated list of values which are to be used as labels for Loki events.

• loki.loglevel: Minimum log level for events sent to the Loki server.

• loki.types: Types of events which are to be sent to the Loki server (lifecycle and/or logging).

acme

This adds ACME support, which allows Let’s Encrypt or other ACME services to issue certificates.

It adds the following global configuration keys:

• acme.domain: The domain for which the certificate should be issued.

• acme.email: The email address used for the account of the ACME service.

• acme.ca_url: The directory URL of the ACME service, defaults to https://acme-v02.api.letsencrypt.org/directory.

It also adds the following endpoint, which is required for the HTTP-01 challenge:

• /.well-known/acme-challenge/<token>

internal_metrics

This adds internal metrics to the list of metrics. These include:

• Total running operations

• Total active warnings

• Daemon uptime in seconds

• Go memory stats

• Number of goroutines

cluster_join_token_expiry

This adds an expiry to cluster join tokens which defaults to 3 hours, but can be changed by setting the cluster.join_token_expiry configuration key.

remote_token_expiry

This adds an expiry to remote add join tokens. It can be set in the core.remote_token_expiry configuration key, and default to no expiry.

storage_volumes_created_at

This change adds support for storing the creation date and time of storage volumes and their snapshots.

This adds the CreatedAt field to the StorageVolume and StorageVolumeSnapshot API types.

cpu_hotplug

This adds CPU hotplugging for VMs. Hotplugging is disabled when using CPU pinning, because this would require hotplugging NUMA devices as well, which is not possible.

projects_networks_zones

This adds support for the features.networks.zones project feature, which changes which project network zones are associated with when they are created. Previously network zones were tied to the value of features.networks, meaning they were created in the same project as networks were.

Now this has been decoupled from features.networks to allow projects that share a network in the default project (i.e those with features.networks=false) to have their own project level DNS zones that give a project oriented “view” of the addresses on that shared network (which only includes addresses from instances in their project).

This also introduces a change to the network dns.zone.forward setting, which now accepts a comma-separated of DNS zone names (a maximum of one per project) in order to associate a shared network with multiple zones.

No change to the dns.zone.reverse.* settings have been made, they still only allow a single DNS zone to be set. However the resulting zone content that is generated now includes PTR records covering addresses from all projects that are referencing that network via one of their forward zones.

Existing projects that have features.networks=true will have features.networks.zones=true set automatically, but new projects will need to specify this explicitly.

instance_nic_txqueuelength

Adds a txqueuelen key to control the txqueuelen parameter of the NIC device.

cluster_member_state

Adds GET /1.0/cluster/members/<member>/state API endpoint and associated ClusterMemberState API response type.

instances_placement_scriptlet

Adds support for a Starlark scriptlet to be provided to Incus to allow customized logic that controls placement of new instances in a cluster.

The Starlark scriptlet is provided to Incus via the new global configuration option instances.placement.scriptlet.

storage_pool_source_wipe

Adds support for a source.wipe Boolean on the storage pool, indicating that Incus should wipe partition headers off the requested disk rather than potentially fail due to pre-existing file systems.

zfs_block_mode

This adds support for using ZFS block filesystem volumes allowing the use of different file systems on top of ZFS.

This adds the following new configuration options for ZFS storage pools:

• volume.zfs.block_mode

• volume.block.mount_options

• volume.block.filesystem

instance_generation_id

Adds support for instance generation ID. The VM or container generation ID will change whenever the instance’s place in time moves backwards. As of now, the generation ID is only exposed through to VM type instances. This allows for the VM guest OS to reinitialize any state it needs to avoid duplicating potential state that has already occurred:

• volatile.uuid.generation

disk_io_cache

This introduces a new io.cache property to disk devices which can be used to override the VM caching behavior.

amd_sev

• security.sev : (bool) is SEV enabled for this VM

• security.sev.policy.es : (bool) is SEV-ES enabled for this VM

• security.sev.session.dh : (string) guest owner’s base64-encoded Diffie-Hellman key

• security.sev.session.data : (string) guest owner’s base64-encoded session blob

This also adds the CRIUType_VM_QEMU value of 3 for the migration CRIUType protobuf field.

ovn_nic_nesting

This adds support for nesting an ovn NIC inside another ovn NIC on the same instance. This allows for an OVN logical switch port to be tunneled inside another OVN NIC using VLAN tagging.

This feature is configured by specifying the parent NIC name using the nested property and the VLAN ID to use for tunneling with the vlan property.

oidc

This adds support for OpenID Connect (OIDC) authentication.

This adds the following new configuration keys:

• oidc.issuer

• oidc.client.id

• oidc.audience

network_ovn_l3only

This adds the ability to set an ovn network into “layer 3 only” mode. This mode can be enabled at IPv4 or IPv6 level using ipv4.l3only and ipv6.l3only configuration options respectively.

With this mode enabled the following changes are made to the network:

• The virtual router’s internal port address will be configured with a single host netmask (e.g. /32 for IPv4 or /128 for IPv6).

• Static routes for active instance NIC addresses will be added to the virtual router.

• A discard route for the entire internal subnet will be added to the virtual router to prevent packets destined for inactive addresses from escaping to the uplink network.

• The DHCPv4 server will be configured to indicate that a netmask of 255.255.255.255 be used for instance configuration.

ovn_nic_acceleration_vdpa

This updates the ovn_nic_acceleration API extension. The acceleration configuration key for OVN NICs can now takes the value vdpa to support Virtual Data Path Acceleration (VDPA).

cluster_healing

This adds cluster healing which automatically evacuates offline cluster members.

This adds the following new configuration key:

• cluster.healing_threshold

The configuration key takes an integer, and can be disabled by setting it to 0 (default). If set, the value represents the threshold after which an offline cluster member is to be evacuated. In case the value is lower than cluster.offline_threshold, that value will be used instead.

When the offline cluster member is evacuated, only remote-backed instances will be migrated. Local instances will be ignored as there is no way of migrating them once the cluster member is offline.

instances_state_total

This extension adds a new total field to InstanceStateDisk and InstanceStateMemory, both part of the instance’s state API.

auth_user

Add current user details to the main API endpoint.

This introduces:

• auth_user_name

• auth_user_method

security_csm

Introduce a new security.csm configuration key to control the use of CSM (Compatibility Support Module) to allow legacy operating systems to be run in Incus VMs.

instances_rebuild

This extension adds the ability to rebuild an instance with the same origin image, alternate image or as empty. A new POST /1.0/instances/<name>/rebuild?project=<project> API endpoint has been added as well as a new CLI command incus rebuild.

numa_cpu_placement

This adds the possibility to place a set of CPUs in a desired set of NUMA nodes.

This adds the following new configuration key:

custom_volume_iso

This adds the possibility to import ISO images as custom storage volumes.

This adds the --type flag to incus storage volume import.

network_allocations

This adds the possibility to list an Incus deployment’s network allocations.

Through the incus network list-allocations command and the --project <PROJECT> | --all-projects flags, you can list all the used IP addresses, hardware addresses (for instances), resource URIs and whether it uses NAT for each instance, network, network forward and network load-balancer.

zfs_delegate

This implements a new zfs.delegate volume Boolean for volumes on a ZFS storage driver. When enabled and a suitable system is in use (requires ZFS 2.2 or higher), the ZFS dataset will be delegated to the container, allowing for its use through the zfs command line tool.

storage_api_remote_volume_snapshot_copy

This allows copying storage volume snapshots to and from remotes.

operations_get_query_all_projects

This introduces support for the all-projects query parameter for the GET API calls to both /1.0/operations and /1.0/operations?recursion=1. This parameter allows bypassing the project name filter.

metadata_configuration

Adds the GET /1.0/metadata/configuration API endpoint to retrieve the generated metadata configuration in a JSON format. The JSON structure adopts the structure "configs" > `ENTITY` > `ENTITY_SECTION` > "keys" > [<CONFIG_OPTION_0>, <CONFIG_OPTION_1>, ...]. Check the list of configuration options to see which configuration options are included.

syslog_socket

This introduces a syslog socket that can receive syslog formatted log messages. These can be viewed in the events API and incus monitor, and can be forwarded to Loki. To enable this feature, set core.syslog_socket to true.

event_lifecycle_name_and_project

This adds the fields Name and Project to lifecycle events.

instances_nic_limits_priority

This introduces a new per-NIC limits.priority option that works with both cgroup1 and cgroup2 unlike the deprecated limits.network.priority instance setting, which only worked with cgroup1.

disk_initial_volume_configuration

This API extension provides the capability to set initial volume configurations for instance root devices. Initial volume configurations are prefixed with initial. and can be specified either through profiles or directly during instance initialization using the --device flag.

Note that these configuration are applied only at the time of instance creation and subsequent modifications have no effect on existing devices.

operation_wait

This API extension indicates that the /1.0/operations/{id}/wait endpoint exists on the server. This indicates to the client that the endpoint can be used to wait for an operation to complete rather than waiting for an operation event via the /1.0/events endpoint.

image_restriction_privileged

This extension adds a new image restriction, requirements.privileged which when false indicates that an image cannot be run in a privileged container.

cluster_internal_custom_volume_copy

This extension adds support for copying and moving custom storage volumes within a cluster with a single API call. Calling POST /1.0/storage-pools/<pool>/custom?target=<target> will copy the custom volume specified in the source part of the request. Calling POST /1.0/storage-pools/<pool>/custom/<volume>?target=<target> will move the custom volume from the source, specified in the source part of the request, to the target.

disk_io_bus

This introduces a new io.bus property to disk devices which can be used to override the bus the disk is attached to.

storage_cephfs_create_missing

This introduces the configuration keys cephfs.create_missing, cephfs.osd_pg_num, cephfs.meta_pool and cephfs.osd_pool to be used when adding a cephfs storage pool to instruct Incus to create the necessary entities for the storage pool, if they do not exist.

instance_move_config

This API extension provides the ability to use flags --profile, --no-profile, --device, and --config when moving an instance between projects and/or storage pools.

certificate_description

Adds a description field to certificate.

disk_io_bus_virtio_blk

Adds a new virtio-blk value for io.bus on disk devices which allows for the attached disk to be connected to the virtio-blk bus.

loki_config_instance

Adds a new loki.instance server configuration key to customize the instance field in Loki events. This can be used to expose the name of the cluster rather than the individual system name sending the event as that’s usually already covered by the location field.

instance_create_start

Adds a new start field to the POST /1.0/instances API which when set to true will have the instance automatically start upon creation.

In this scenario, the creation and startup is part of a single background operation.

clustering_evacuation_stop_options

This introduces new options for the cluster.evacuate option:

• stateful-stop has the instance store its state to disk to be resume on restore.

• force-stop has the instance immediately stopped without waiting for it to shut down.

boot_host_shutdown_action

This introduces a new boot.host_shutdown_action instance configuration key which can be used to override the default stop behavior on system shutdown. It supports the value stop, stateful-stop and force-stop.

agent_config_drive

This introduces a new agent:config disk source which can be used to expose an ISO to the VM guest containing the agent and its configuration.

network_state_ovn_lr

Adds a new LogicalRouter field to the NetworkStateOVN struct which is part of the GET /1.0/networks/NAME/state API.

This is used to get the OVN logical router name.

image_template_permissions

This adds uid, gid and mode fields to the image metadata template entries.

storage_bucket_backup

Add storage bucket backup support.

This includes the following new endpoints (see RESTful API for details):

• GET /1.0/storage-pools/<pool>/buckets/<bucket>/backups

• POST /1.0/storage-pools/<pool>/buckets/<bucket>/backups

• GET /1.0/storage-pools/<pool>/buckets/<bucket>/backups/<name>

• DELETE /1.0/storage-pools/<pool>/buckets/<bucket>/backups/<name>

• GET /1.0/storage-pools/<pool>/buckets/<bucket>/backups/<name>/export

storage_lvm_cluster

This adds a new lvmcluster storage driver which makes use of LVM shared VG through lvmlockd.

With this, it’s possible to have a single shared LVM pool across multiple servers so long as they all see the same backing device(s).

shared_custom_block_volumes

This adds a new configuration key security.shared to custom block volumes. If unset or false, the custom block volume cannot be attached to multiple instances. This feature was added to prevent data loss which can happen when custom block volumes are attached to multiple instances at once.

auth_tls_jwt

This adds the ability to use a signed JSON Web Token (JWT) instead of using the TLS client certificate directly.

In this scenario, the client derives a JWT from their own TLS client certificate providing it as a bearer token through the Authorization HTTP header.

The JWT must have the certificate’s fingerprint as its Subject and must be signed by the client’s private key.

oidc_claim

This introduces a new oidc.claim server configuration key which can be used to specify what OpenID Connect claim to use as the username.

device_usb_serial

This adds a new configuration key serial for device type usb. Feature has been added, to make it possible to distinguish between devices with identical vendorid and productid.

numa_cpu_balanced

This adds balanced as a new value for limits.cpu.nodes.

When set to balanced, Incus will attempt to select the least busy NUMA node at startup time for the instance, trying to keep the load spread across NUMA nodes on the system.

image_restriction_nesting

This extension adds a new image restriction, requirements.nesting which when true indicates that an image cannot be run without nesting.

network_integrations

Adds the concept of network integrations and initial support for OVN Interconnection.

New API:

• /1.0/network-integrations (GET, POST)

• /1.0/network-integrations/NAME (GET, PUT, PATCH, DELETE, POST)

Each integration is made of:

• name

• description

• type (only ovn for now)

• configuration

  • ovn.northbound_connection (database connection string for the OVN Interconnection database)

  • ovn.ca_cert (optional, SSL CA certificate for the OVN Interconnection database)

  • ovn.client_cert (optional, SSL client certificate to connect to the OVN Interconnection database)

  • ovn.client_key (optional, SSL client key to connect to the OVN Interconnection database)

  • ovn.transit.pattern (Pongo2 template to generate the transit switch name)

Those integrations attach to network peers through some new fields:

• type (local for current behavior, remote for integrations)

• target_integration (reference to the integration)

instance_memory_swap_bytes

This extends limits.memory.swap to allow for a total limit in bytes.

network_bridge_external_create

This adds the ability for bridge.external_interfaces to create a parent interface using a interface/parent/vlan syntax.

storage_zfs_vdev

This adds support for mirror, raidz1 and raidz2 ZFS vdev types by extending storage source configuration.

container_migration_stateful

A migration.stateful configuration key was introduced.

It’s a Boolean flag set to true whenever the container is in a stateful mode during the start, stop, and snapshot functions.

This makes it less likely for users to run into CRIU errors when copying containers to another system.

profiles_all_projects

This adds support for listing profiles across all projects through the all-projects parameter on the GET /1.0/profilesAPI.

instances_scriptlet_get_instances

This allows the instance scriptlet to fetch a list of instances given an optional Project or Location filter.
