Docker with Puppet Run a conatiner using a native volume

Question

How does docker know if it has to use a bind mount or a volume while running a container? How can i use a native volume stored on my host machine to be used while running a docker container via puppet?

Answer 1

When using the volumes array with docker::run, the command on the backend will know if it needs to use bind mounts or volumes based on data passed to the -v option.

Running docker::run with native volumes:

docker::run { 'helloworld':
  image   => 'ubuntu:precise',
  command => '/bin/sh -c "while true; do echo hello world; sleep 1; done"',
  volumes => ['my-volume:/var/log'],
}
