LXD 3.2 has been released

23rd of June 2018

Introduction

This month's LXD release comes with a lot of bugfixes and performance improvements, especially for those using LXD clustering.

Feature wise, this release has a lot of improvements for those using the proxy device type first introduced in LXD 3.0, foundation work for image download improvements in nested environments and closes a big gap in our storage story by allowing containers to be copied and moved between pools.

The changes in this release include

Features:

  • Added a new API to /dev/lxd allowing for direct download of public
    and cached images from the host (requires security.devlxd.images)
