That's been on my TODO list, so unfortunately no  proper human-readable 
documentation for that exists at the moment. Perhaps this thread is the 
motivation I need to get working on that.

If you can read k8s YAML this might help serve as a starting point:

The elevator-pitch version:
* Initialize your persistent storage: <container-cmd ...> quay.io/samba.org/
samba-server:latest init
* Polling join: <container-cmd ...>  quay.io/samba.org/samba-server:latest 
must-join --files --join-file=/etc/join-data/join.json
* Start winbind: <container-cmd ...>  quay.io/samba.org/samba-server:latest 
run winbind
* Start sbmd: <container-cmd ...>  quay.io/samba.org/samba-server:latest run 
(the trick here that makes it look simple is that I'm leaving out he shared 
mounts and the env vars ;-) )

For me, the issue is that I've spent a lot of time focused on kubernetes and 
samba-operator [1] which does already implement domain joins with a member 
server, and is documented. It's just that samba-container doesn't explain how 
to do it manually :-(  I really want the other projects to stand on their own 
without k8s though so I'd really like to have docs for something like a full 
member server on docker-compose.
