loft-sh/vcluster v0.6.0-alpha.5 on GitHub

Pause and Resume vclusters

vcluster is now able to pause and resume. Pausing a vcluster means to temporarily scale down the vcluster and delete all its created workloads on the host cluster. This can be useful to save computing resources used by vcluster workloads in the host cluster.

For more information please checkout the vcluster docs

Expiring kube configs & automatic service account creation

vcluster is now able to automatically create service account tokens for generated kube configs, which allow you to easily create kube configs for other vcluster users that should not be cluster admin. For example:

# Create a kube config for a cluster viewer
vcluster connect my-vcluster -n my-vcluster --service-account viewer --cluster-role view

# OR: create a kube config for a cluster admin
vcluster connect my-vcluster -n my-vcluster --service-account admin --cluster-role cluster-admin

# OR: create a kube config that expires after an hour
vcluster connect my-vcluster -n my-vcluster --service-account viewer --cluster-role view --token-expiration 3600

This makes it also possible to use vcluster more easily without ingresses that require ssl passthrough. For more information please checkout the vcluster access docs and vcluster ingress docs

Support for VolumeSnapshots

vcluster now supports syncing of volume snapshots between the host and virtual cluster, that can be enabled via a values.yaml:

rbac:
  clusterRole:
    enabled: true
  role:
    extended: true

syncer:
  extraArgs:
  - --sync=volumesnapshots

and then used via:

vcluster create ... -f values.yaml

Other Changes

cli: New flag --insecure for vcluster connect to create a kube config with insecure-skip-tls-verify
cli: Notify the user about incompatible workdir file when running vcluster create
cli: Add v1.23 support for k3s
syncer: Start controllers after api server started
syncer: Fixed syncer cache race condition after Service creation
chart: Fixed a problem where k3s would not startup correctly on cgroupsv2 nodes (#264)
other: For each release there will be a new vcluster-images.txt which holds all the needed images by vcluster. In addition, we include two scripts to download and push the needed images automatically
