The isCoreDNSVersionSupported() check assumes that there is a running kubelet, that manages the CoreDNS containers. If the containers are being created it is not possible to fetch their image digest. To workaround that, a poll can be used in isCoreDNSVersionSupported() and wait for the CoreDNS Pods are expected to be running. Depending on timing and CNI yet to be installed this can cause problems related to addon idempotency of "kubeadm init", because if the CoreDNS Pods are waiting for another step they will never get running. Remove the function isCoreDNSVersionSupported() and assume that the version is always supported. Rely on the Corefile migration library to error out if it must. |
