Installation of CRD fails #951

Closed timbrd closed 3 months ago

Description

I am trying to install k8up operator following the official tutorial. The installation of the CRDs unfortunately fails:

❯ k apply -f https://github.com/k8up-io/k8up/releases/download/v2.8.0/k8up-crd.yaml
customresourcedefinition.apiextensions.k8s.io/archives.k8up.io created
customresourcedefinition.apiextensions.k8s.io/backups.k8up.io created
customresourcedefinition.apiextensions.k8s.io/checks.k8up.io created
customresourcedefinition.apiextensions.k8s.io/prunes.k8up.io created
customresourcedefinition.apiextensions.k8s.io/restores.k8up.io created
customresourcedefinition.apiextensions.k8s.io/schedules.k8up.io created
customresourcedefinition.apiextensions.k8s.io/snapshots.k8up.io created
The CustomResourceDefinition "prebackuppods.k8up.io" is invalid: metadata.annotations: Too long: must have at most 262144 bytes

Is there really a bug in the CRD file? What might cause this error?

Version 2.7.2 works as expected:

❯ k apply -f https://github.com/k8up-io/k8up/releases/download/v2.7.2/k8up-crd.yaml
customresourcedefinition.apiextensions.k8s.io/archives.k8up.io configured

@timbrd

Can you try this?

k apply -f https://github.com/k8up-io/k8up/releases/download/v2.8.0/k8up-crd.yaml --server-side

The problem is most likely with the kubectl.kubernetes.io/last-applied-configuration annotation that kubectl uses to track the apply. It basically contains a copy of the whole CRD and it looks like with the latest release they just crossed the threshold of the allowed annotation size.

Using --server-side with the apply doesn't create the kubectl.kubernetes.io/last-applied-configuration annotation, so it should apply.

Sorry for the late response, I wasn't able to check your suggestion. Using the server side rendering, my cluster could load the CRD.
