MicroCloud 3.1 release notes¶
This is a feature release and is not recommended for production use. It’s the first feature release of the new track 3.
Highlights¶
This section highlights new and improved features in this release.
Cluster Manager¶
Cluster Manager allows you to manage and monitor multiple MicroCloud clusters in a single application. Starting with this release, a MicroCloud can be connected to an existing deployment of Cluster Manager.
Check How to manage multiple clusters with the Cluster Manager to deploy Cluster Manager. The Requirements section lists the requirements to get started. See the Architecture of the MicroCloud Cluster Manager page for an in-depth view of the core components.
If you already have a Cluster Manager deployment, see Enroll your first cluster to learn how to enroll a MicroCloud cluster.
Temporary UI access link¶
It’s fast to deploy a MicroCloud and gain the ability to spawn resources from the command line.
To provide the same experience when using the UI, we added a new question to the end of the
interactive microcloud init questionnaire:
Would you like to create an initial UI access link? (yes/no) [default=yes]:
If you answer yes (default), MicroCloud creates a temporary UI access link that allows you to immediately enter
the LXD UI after MicroCloud is installed.
The temporary access lasts for 24 hours and is intended to allow you to perform further setup (such as configuring permanent access).
This requires a 6+ version of LXD, which is currently a feature track (non-LTS).
MicroOVN 26.03 support (experimental)¶
MicroCloud 3.1 can use MicroOVN 26.03, which is a feature release currently available through their latest/edge channel. Using this instead of the MicroOVN 24.03 LTS release (snap channel 24.03/stable) allows us to test the latest features before the 26.03 release is published as the next LTS.
Make sure you have the core26 snap installed before trying to install MicroOVN from latest/edge:
snap install core26 --channel="latest/edge"
snap install microovn --channel="latest/edge" --cohort="+"
Upgrading to the new version¶
If you are currently running MicroCloud 2 LTS, be aware that upgrading to track 3 is not yet recommended or supported for production clusters. See the Upgrade MicroCloud snap guide for information on how to switch the MicroCloud track.
