Weekly status for the week of the 22nd of February to the 28th of February.

Introduction

This past week was primarily a bug fix and improvement week, however LXD did get two new project related features available in the CLI.

LXD

This past week LXD gained support for setting images.auto_update_cached and images.auto_update_interval config keys on a per-project basis.

Following on from last week’s feature to support assigning one or more projects to a trusted client certificate, with the effect of restricting that client certificate to the equivalent of the operator role on those projects, and denying access to any other projects, we have now added support for using those options with lxc config trust add command using the --restricted and --projects flags.

We have also continued converting our API documentation to automated builds using swagger.

The following bugs were fixed:

  • Allow copy of instance within a non-default project.
  • Allow using a published VM image that is >10GB in size with BTRFS (previously we were truncating BTRFS optimized image VM volumes to default volume size after image unpack with the effect of corrupting the newly created instance root drive).

LXC

We have continued our work on cgroup hardening using file description only container attaching.

Also an issue with the way that network interfaces were moved from the host into the container, before being renamed, meant that in certain scenarios (where one network interface was renamed to the name of another interface that was being moved in such that they conflicted) the container would refuse to start.

This has been fixed by renaming all network interfaces to a random name as they are moved into the container, and then renamed to the desired name after that.

Distrobuilder

An issue that was preventing Oracle and CentOS image builds (introduced by https://github.com/lxc/distrobuilder/commit/c429f89ec113ad226ae2294e5a8a0938a45caf49) has been fixed. In addition the Oracle images now have /bin symlinked to /usr/bin if missing.

Finally the source for Void Linux checksums has been updated.

Dqlite (RAFT library)

A memory leak when ignoring snapshot install has been fixed. Snapshot installation is now retried.

Youtube channel

We’ve started a Youtube channel with live streams covering LXD releases and its use in the wider ecosystem.

You may want to give it a watch and/or subscribe for more content in the coming weeks.
