NOTE: latest etcd release 3.0.4 on alpine 3.4
This was a clone of elcolio/etcd.
The -data-dir is a volume mounted to /data, and the default ports are bound to Etcd and exposed.
Recently added a run script so that http is not hard-coded into the Dockerfile (for running over SSL). Just overwrite $CLIENT_URLS and $PEER_URLS at runtime (these are the listening URLs). You'll still need to set the -advertise-client-urls and -initial-advertise-peer-urls flags if the container will be part of a cluster.
Since the image uses an ENTRYPOINT it accepts passthrough arguments to etcd.
