let -notify= send commands on the docker API

[cnf]

I'd like to keep docker-gen running in its own container, seeing as it already has access to the docker API, could docker-gen support a kill -s HUP or a restart on the docker API?

This way, we can just put the templates in a shared volume, and restart / kill -HUP a container running from that config.

One way you might be able to do that w/ the current features is to generate a bash script that:

1. writes out the template you would generate w/ a here document and
2. runs docker restart .

Your notify command would then call that bash script w/ something like -notify "bash -C /tmp/script.sh"

@cnf v 0.3.4 solves this for you now?

This should be supported via -notify-sighup now.
