helm template oci://registry.cloudogu.com/k8s/ecosystem-corefails withError: execution error at (ecosystem-core/templates/00-validate-preconditions.yaml:2:6): CRD k8s.cloudogu.com/v1/Component is not installed.Which is an unpleasant surprise.
...which seems difficult to fix.
In helm we seem not to be able to detect
template. We can check iif .Release.IsDryRunbut in dry run (with a live cluster) we actually want to validate. We can also not rely onif or .Release.IsInstall .Release.IsUpgradebecausetemplateseems to set these as well 🙄So I actually did no change anything, just doc how to do a template if anyone ever wanted to do that.
