vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.

Findings from v0.5.0-beta.0 #253

Closed olljanat closed 2 years ago

olljanat commented 2 years ago

I'm actively testing v0.5.0-beta.0 now so it probably easiest to collect all new findings under one issue and others comment them here too.

  1. Image versions on vcluster and helm charts are not in sync. New k8s cluster deployment uses K8s v1.22.4 and etcd 3.5.1-0 but helm chart https://github.com/loft-sh/vcluster/blob/main/charts/k8s/values.yaml uses K8s v1.21.5 and etcd 3.4.13-0. That why my upgrade attempt from v0.5.0-alpha.7 to v0.5.0-beta.0 failed as etcd does not support downgrade.

@olljanat thanks for the issue! You created the vcluster via the CLI and upgraded it via helm correct? You'll need to use the --reuse-values option with helm or use vcluster create --upgrade instead to preserve the automatically provided values from vcluster create or otherwise the values are reset to the chart values on upgrade.

Ah, I got confused that vcluster upgrade update only CLI and totally missed vcluster create --upgrade option so yes I did upgrade with helm. However chart upgrade worked fine too after including image versions to it manually.
