discovery.zen.ping.unicast.hosts: [ "${ES_ENV_M1}:9300","${ES_ENV_M2}:9300","${ES_ENV_M3}:9300" ]

Do you have three containers (one for each master) under the same VM? Or a single container running three ES nodes?

If three separate containers are involved then have you tried the setting

network.publish_host=$(docker-machine ip default)
