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