Checkmk Werk 14126: KUBE agent_kube: clarify error messages caused by unsupported Kubernetes version

ID: 14126 Title: KUBE agent_kube: clarify error messages caused by unsupported Kubernetes version Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 With this werk, the agent verifies whether the Kubernetes version is supported by Checkmk. If it is known that an API server with a certain version is incompatible, the agent will now provide a helpful error message. Different flavors of Kubernetes are not verified. In the event, that the version of the API server deviates from the versioning scheme used by Kubernetes, processing the API data is still attempted on a best effort basis. Errors related to unknown versioning schemes can be inspected by increasing the verbosity of the agent via the command line (you can find the command line tool by using cmk -D).
