In this thread we would like to inform our users of the progress within the MicroK8s project.

Sprint report of 15 to 29 November 2021

The theme of this sprint was: “Prepare for the v1.23 release”

• We merged the support for worker only nodes in dqlite based clusters. This included:

  • Refactor the clustering commands in a pythonic way
  • Add tests for clustering worker nodes
  • Label nodes based on their role
  • Update our docs page

• We added support for MicroK8s on M1 Mac

• We reviewed and merged the following external contributions, thank you:

  • ingress for Kubernetes dashboard addon
  • upgrade keda to the latest version
  • Linkerd upgrade
  • upgrade metrics server
  • upgrade jaeger operator
  • Remove deprecated configuration from containerd

• Updated the nginx ingress controller add-on

• On strictly confined MicroK8s we now support editing manifests with microk8s kubectl edit. Try it with: snap install microk8s --channel=latest/edge/strict

• For the charmed MicroK8s we landed two PRs to

  • configure SANs in MicroK8s units and
  • prevent breaking cluster by downgrading to older versions

• Added a documentation page on NVIDIA DGX support

• The upcoming released 1.23 will have the following changes on its default args:

  • k8s service profiling will be disabled
  • event-ttl will be set to 5min
  • insecure-port will be removed

• Bug/usability fixes:

  • callback token removal so distributed ops do not try to reach departed nodes
  • the inspection script will detect missing modules on RPi on 21.10
