Hi Team, I am following these instructions mentioned here to run Flink K8s operator on Google Kubernetes Engine. After running the following command the cert-manager pods fail to start.

Copy code

kubectl create -f <https://github.com/jetstack/cert-manager/releases/download/v1.8.2/cert-manager.yaml>

I checked the logs for pods. I can see this error in pod logs

Copy code

exec /app/cmd/cainjector/cainjector: exec format error

Has anyone faced a similar issue ?

we havent tried this but you can try using a newer cert manager version

or if you can’t make it work you can file a jira ticket and disable the webhook as a workaround

By the way what is the use of this cert-manager resources?

This got resolved. I was running arm64 image which was built on my M1 mac, however the GKE nodes had amd64 arch. After fixing the images it got resolved.

@Gyula Fóra Do we have snapshot images of flink-kubernetes-operator available publicly or we just have to build it on my local ?

Every commit to main triggers a corresponding snapshot build to https://github.com/orgs/apache/packages?repo_name=flink-kubernetes-operator
