Weekly status for the week of 1st May to 7th May.

Introduction

Last week the LXD team were in Prague for the Canonical Engineering sprint. It was a great opportunity for the team to meet in person and work together, as well as discuss future plans both within the team and with other teams at Canonical.

Here is a photo of the LXD team members, including the Cloud and UI teams.

David Edler is also on the LXD UI team, but unfortunately he was unable to attend the Prague sprint.

Additionally @stgraber has added a video introducing the new LXD UI project, with an early look at how to set it up and what features it includes so far:

Job openings

Canonical Ltd. strengthens its investment into LXD and is looking at building multiple squads under the technical leadership of @stgraber.

As such, we are looking for first line managers (highly technical) and individual contributors to grow the team and pursue our efforts around scalability and clustering.

All positions are 100% remote with some travel for internal events and conferences.

For more info please see LXD related openings at Canonical Ltd (2022-2023)

LXD

New features:

  • Added support for browser OIDC login.

Improvements:

  • Changed the default behaviour of lxc publish to that it fails the publish if the alias already exists, and added a --reuse flag as a way to override that which will lead to the current image being deleted and replaced.
  • Improved the flexibility of the devID matching for IO stats in the metrics subsystem to workaround bugs in some versions of the Linux kernel.
  • Added lxc freeze as an alias to lxc pause for consistency with the FROZEN state that the instance enters. This is for conceptual consistency with the LXD UI.

Bug fixes:

  • Fixed an issue where copying/refreshing a local storage pool volume in a cluster from one member to another would fail.
  • Fixed an issue when upgrading from LXD 3.x to 4.x and then onto 5.x where the instance snapshot records that are created in storage_volumes_snapshots table are not removed from the storage_volumes table.
  • Fixed two issues with /dev/lxd issue from inside VMs (when using lxd-agent). The first was the it was not possible to access /dev/lxd when using nested VMs. The 2nd issue was that when a cluster was being initialized the new cluster certificate was not applied to the lxd-agent /dev/lxd listener and so failed to work on the first cluster member.
  • Fixed an issue that allowed any authenticated user to create a cluster group. Now only admins can do it.

LXD Charm

Improvements:

  • Gracefully handle when the remote unit/app is already gone.
  • Add more type hints and improve set_peer_data helpers.

YouTube videos

The LXD team is running a YouTube channel with live streams covering LXD releases and weekly videos on different aspects of LXD. You may want to give it a watch and/or subscribe for more content in the coming weeks.
