Incus 6.4 has been released

Aug 9, 2024

Introduction

The Incus team is pleased to announce the release of Incus 6.4!

This is a very balanced release with something new for everyone!

It comes with a number of bugfixes and new features to help with the OCI support added in the previous release. It also brings in a number of new features for more complex shared/cluster environments. And it's jam packed with bugfixes, fixing a lot of annoyances around storage, clustering, OpenID authentication, auditing and more.

As usual, you can try it for yourself online: https://linuxcontainers.org/incus/try-it/

Enjoy!

New features

Cluster group configuration

Cluster groups now have a standard configuration table like most other Incus objects.

This means the usual set of commands and APIs:
- incus cluster group edit
- incus cluster group get
- incus cluster group set
- incus cluster group show
- incus cluster group unset

Per-cluster group CPU baseline and flags for VMs

Building on top of that support for cluster group configuration, we now have support for defining the VM CPU baseline on a per cluster group basis.

This makes it possible to have one cluster group per CPU model/generation and have Incus compute the common set of CPU flags for those servers.

For example, incus cluster group set foo instances.vm.cpu.x86_64.baseline=kvm64 instances.vm.cpu.x86_64.flags=auto will have Incus automatically go through the servers in the foo cluster group and then fill in the flags configuration key with the set of common CPU flags.

But this also allows setting up your own completely custom CPU defintion, for example, incus cluster group set foo instances.vm.cpu.x86_64.baseline=EPYCv2 instances.vm.cpu.x86_64.flags=-svm will expose a basic 2nd generation AMD EPYC CPU with the virtualization extension (svm) disabled.

Using a sub-path of a volume as a disk

It's now possible to use a path within an existing custom volume as the source for a disk entry.

stgraber@castiana:~$ incus launch images:ubuntu/24.04 demo
Launching demo
stgraber@castiana:~$ incus launch images:ubuntu/24.04 demo-sub
Launching demo-sub
stgraber@castiana:~$ incus storage volume create default demovol
Storage volume demovol created
stgraber@castiana:~$ incus config device add demo demovol disk pool=default source=demovol path=/mnt/demovol
Device demovol added to demo
stgraber@castiana:~$ incus exec demo bash
root@demo:~# mkdir -p /mnt/demovol/sub/path/
root@demo:~# echo world > /mnt/demovol/sub/path/hello
root@demo:~#·
exit
stgraber@castiana:~$ incus config device add demo-sub demovol disk pool=default source=demovol/sub/path path=/mnt/demovol
Device demovol added to demo-sub
stgraber@castiana:~$ incus exec demo-sub bash
root@demo-sub:~# cat /mnt/demovol/hello·
world

In this example, a demovol custom volume is created, then attached to the demo container, a sub-directory is created in that volume and that sub-directory is then attached to another container, demo-sub.

Per storage pool projects limits

Incus projects can have resource limits applied to them, ideal when providing access to a project to a third party. Up until now, it was possible to limit the total disk usage within a project, but that would apply to all storage pools.

As it's common to have different storage pools representing different storage characteristics (local vs remote) or class (ssd vs hdd), it's useful to have a way to provide limits per storage pool.

To do so, a new configuration key, limits.disk.pool.POOLNAME is now available in project configuration. Setting the limit to 0 fully disables that storage pool and causes it to disappear from the storage pool listing in that project.

Here we can see a project get set up with a disk limit, first hiding one of the pools, then filling the other before setting a limit on the previously hidden pool.

Up until now, all OVN networks have had a uplink network set (network property).
That's the network on which the external facing router port will sit and through which all ingress/egress into/out-of the OVN network will happen.

Incus picks an IPv4 (and/or IPv6) address on that uplink network and then uses it to route all the traffic out of the virtual network and onto the physical network.

Now a special value of none for that network property will instruct Incus to create an OVN network which is not connected to any uplink and is threfore fully isolated.

root@server01:~# incus network create ovn-isolated network=none --type=ovn
Network ovn-isolated created
root@server01:~# incus launch images:ubuntu/24.04 c1 --network ovn-isolated

^C

Here we can see an isolated network being created and a container being placed on it.
The network provides IPv4 and IPv6 addresses as usual, but no traffic can come out.

Per-instance LXCFS

A new server configuration key, instances.lxcfs.per_instance can now be enabled to have Incus start a dedicated LXCFS instance for every container.

This is in contrast to the default of having a single LXCFS instance run for the entire system.

Enabling this comes at a slightly higher resource usage per container, but reduces the risk of one container flooding the shared LXCFS instance as well as make it so a LXCFS crash only affects one container.

stgraber@castiana:~$ pgrep -a lxcfs
1101 /opt/incus/bin/lxcfs /var/lib/incus-lxcfs
stgraber@castiana:~$ incus config set instances.lxcfs.per_instance=true
stgraber@castiana:~$ incus restart demo
stgraber@castiana:~$ pgrep -a lxcfs
1101 /opt/incus/bin/lxcfs /var/lib/incus-lxcfs
962122 lxcfs -f -p /run/incus/demo/lxcfs.pid --runtime-dir /run/incus/demo/lxcfs /var/lib/incus/devices/demo/lxcfs

Support for environment file at create/launch time

To make it easier to run OCI containers, it's now possible to specify environment variables through an environment variable file which gets read at creation time and converted to Incus configuration options.

stgraber@castiana:~$ cat mysql.env
MYSQL_DATABASE=wordpress
MYSQL_USER=wordpress
MYSQL_PASSWORD=wordpress
MYSQL_RANDOM_ROOT_PASSWORD=1
