Limit scope of container install to specific minions about docker-formula

[gravyboat]

As far as I know this formula currently doesn't have support for Docker Swarm. If you feel like adding support for it that would be awesome!

Well, swarm is just another container to be started. Thats why I am asking if it is possible to assign containers to specific nodes, as swarm has two different roles, a master and workers. If there is a way to do this in the pillar, already, that would be great. Otherwise I'll have to think about something.

But sure, It should be fairly easy to contribute this once it's finished.

Looking at the formula it doesn't currently appear to be configured in such a way. It's just to get docker itself configured and installed on systems. From there I imagine most people are writing additional states to handle their provisioning. You may want to simply add a swarm.sls that sets up the swarm container via values set in the pillar. Should be pretty easy to do.

Alright, thank you. Wasn't sure if there's already a way builtin or not. Looks like what you describe will be my way forward, then.

Sounds good! If you implement this please make a PR against the formula as I'm sure other users would benefit from the addition.

@juwi Oh I forgot, I made this project a while back if you need a place to get started in terms of spinning the container up: https://github.com/gravyboat/docka-docka-docka/blob/master/docka-salt/srv/salt/docker/docka.sls
