getting the size of your etcd

When running etcd in a kubernetes cluster, there is a size limit of 6G atleast in GCP. To see how much space your etcd in a cluster, you can run the following commands

Get the etcd pods

kubectl -n kube-system get pods | grep etcd

Getting the size used so far

kubectl -n kube-system exec -it etcd-<your-master-node> -- \

  etcdctl --endpoints=https://127.0.0.1:2379 \

  --cert=/etc/kubernetes/pki/etcd/server.crt \

  --key=/etc/kubernetes/pki/etcd/server.key \

  --cacert=/etc/kubernetes/pki/etcd/ca.crt \

  endpoint status --write-out=table
