Volumes also don't appear to be working for me either. I can start the
container, but the mounted volume is always empty inside the container,
despite the host having two volumes. As the original poster says, if I
just use the docker command directly, the volume mount works as expected.
- name: Start Registry
docker: image={{docker_image}} state=running
volumes="/etc/docker-registry/keys:/etc/docker-registry/keys" name=registry
See anything wrong?
