Choosing a port in advance is racy. A better solution is to use a Unix Domain socket in the per-etcd-instance data directory. Then the name can be determined in advance and there's no risk of conflicts with other etcd instances. With unix:// for the endpoint, we have to be a bit more careful about passing a TLS config to the etcd client library because for unix://, in contrast to http://, it tries to use an incomplete config which then fails to establish the connection.
