Renew SSL certificates

Introduction

About every 90 days the SSL certificates for all domains have to be renewed manually, because the cluster is not configured to do it automatically.

Steps

1. Go to the "Variables" section in the Terraform workspace: k8s-ambimax-intern/variables.
2. Look for the variable cert_version and increase the value by one. (e. g. 8 -> 9)
3. Start a new run by clicking on "Actions" -> "Start new run" in the upper right corner:
   • Description: "Renew certificates"
   • Type: "Plan and apply"
4. Apply the plan after the run finished.
