I have created my cluster several times in microk8s but after 2 or 3 weeks the master node stops working well, only the service does not start and neither do the nodes, it works fine for a while, I have made the tarball and I have inspected it but I cannot find nothing specific:
1.- microk8s status
microk8s is not running. Use microk8s inspect for a deeper inspection.
2.- error: Get “https://127.0.0.1:16443/api/v1/namespaces/kube-system/services?labelSelector=kubernetes.io%2Fcluster-service%3Dtrue”: dial tcp 127.0.0.1:16443: connect: connection refused - error from a previous attempt: unexpected EOF
3.- microk8s kubectl logs -n kube-system -l component=kube-apiserver
error: Get “https://127.0.0.1:16443/api/v1/namespaces/kube-system/pods?labelSelector=component%3Dkube-apiserver”: dial tcp 127.0.0.1:16443: connect: connection refused - error from a previous attempt: unexpected EOF
4.- microk8s.inspect (all is running):
