Is it possible to give each scalable instance a host name? I'm thinking about what gets passed to docker -h
or actually looking for any way to identify an instance number from inside the container.
Any persistent and unique per instance thing will do.
(i'm building a solrcloud cluster, and when doing azk restart, i need to tell each instance who they are, otherwise they just join as a whole new node and don't know which shard they should be responsible for)
