@jpechane, any idea how to make the "--auth" parameter optional, depending on how an env var passed when starting a container from that image? I could create a separate file of course but really hoped it can be avoided, so the example image can be use clustered and non-clustered. Thanks!

I.e. what I'm looking for is this:

if (USE_AUTH) {
     CMD ["mongod", "--replSet", "rs0", "--auth"]
}
else {
     CMD ["mongod", "--replSet", "rs0"]
}

How about introducing a script that will start the mongo and use it in CMD instruction? The script can then easily add/remove options as needed?
