I want to deploy an ETC cluster with 3 nodes with Docker. So I use a dicovery url for that purpose. The problem Im having is that when I delete a etcd container, and start a new one, then it cannot rejoin to the cluster. Docker log says: member "XXX" has previously registered with discovery service token (https://discovery.etcd.io/yyyy) But etcd could not find valid cluster configuration in the given data dir (/data).
I am using volume for folder /data and /waldir Also using --net=host so it is using the same host IP always.
But why can't the new container re-join to the cluster? Where the cluster information is saved inside the container?
Help will be appreciated. Thanks.
