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 a 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 a 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.

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 a 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.

network_leases#

Adds a new /1.0/networks/NAME/leases API endpoint to query the lease database on bridges which run a 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

  • 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. shiftfs).

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

    • Track NUMA node per core

    • Track base and turbo frequency per socket

container_disk_shift#

Adds the shift property on disk devices which controls the use of the shiftfs 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 shiftfs 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.

instances#

This introduces the concept of instances, of which currently the only type is container.

image_types#

This introduces support for a new Type field on images, indicating what type of images they are.

resources_disk_sata#

Extends the disk resource API struct to include:

  • Proper detection of SATA devices (type)

  • Device path

  • Drive RPM

  • Block size

  • Firmware version

  • Serial number

clustering_roles#

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.

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#

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#

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.

resources_system#

This adds system information to the output of /1.0/resources.

storage_buckets#

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#

Adds support for AMD SEV (Secure Encrypted Virtualization) that can be used to encrypt the memory of a guest VM.

This adds the following new configuration options for SEV encryption:

  • 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

storage_pool_loop_resize#

This allows growing loop file backed storage pools by changing the size setting of the pool.

migration_vm_live#

This adds support for performing VM QEMU to QEMU live migration for both shared storage (clustered Ceph) and non-shared storage pools.

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:

  • limits.cpu.nodes : (string) comma-separated list of NUMA node IDs or NUMA node ID ranges to place the CPUs (chosen with a dynamic value of limits.cpu) in.

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 a 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.
