I am running EKS cluster in the AWS. The version is 1.25. Today I start to get this message:
Internal error occurred: failed calling webhook "vingress.elbv2.k8s.aws": failed to call webhook: Post "https://aws-load-balancer-webhook-service.kube-system.svc:443/validate-networking-v1-ingress?timeout=10s": x509: certificate signed by unknown authority
How I can fix that?
The problem was in the old version of the cert-manager. Upgrade has fixed the problem
