I recently had an issue with my kube-apiserver restarting all the time, which meant I couldn’t use kubectl.

This is however not the case for me because my deployed software needs a specific version of kubernetes and docker with helm2 so I’m not able to update my cluster until my software vendor supports a newer kubernetes version.

     mirror_type: "srv",
     signature_type: "fingerprints",
     fingerprints: "/usr/share/keys/pkg",
