Support for kubernetes 1.29 or possibility to disable version check

Open rbuffi opened this issue 10 months ago • 1 comments

Is your feature request related to a problem? Please describe.

We are using kubernetes 1.29 and wan't a proof of concept with AKO. When deploying AKO version 1.11.3 we receive the error that K8s 1.29 API is not supported.

Describe the solution you'd like

Faster AKO releases or the possibility to disable the check by environment variable.

Describe alternatives you've considered

Deploying k8s cluster 1.28 for POC but we would like to use 1.29 because this is out prod k8s version

We needed to use ako on a v1.30 cluster and eventually we decided to patch the code and build a patched image, to remove the kubernetes version check. Therefore, we pushed the patched image on a local repository.

We simply cloned the code, from the tag release-1.11.4, and commented the following lines in the file /cmd/ako-main/main.go :

175		if lib.CompareVersions(serverVersion, ">", lib.GetK8sMaxSupportedVersion()) ||
176			lib.CompareVersions(serverVersion, "<", lib.GetK8sMinSupportedVersion()) {
177			akoControlConfig.PodEventf(corev1.EventTypeWarning, lib.AKOShutdown, "Unsupported kubernetes apiserver %s version detected", serverVersion)
178			utils.AviLog.Fatalf("Unsupported kubernetes apiserver version detected. Please check the supportability guide.")
179		}

Than you need to build the image locally with:

make docker

And pushed it to a local repository that the cluster can use to get images.

We use the helm chart to deploy ako, so you need to edit the image repository and eventually the pull secret:

image:
  repository: local.repository/ako/ako
  pullPolicy: IfNotPresent
  pullSecrets:
     - name: local-registry-secret

So far it works normal, with 0 restarts.
