Hello,
I'm trying to use Docker with Ansible to build a Docker image, but am
running into an issue. Any help would be appreciated.
Basically, I want to put my docker files in my role's 'files' directory and
not have to specify a path for the docker_image task. Or, if I do have to
specify a path, I'd like it to be relative.
Ansible -> v1.7.1
Python ->2.7.6
Docker-py -> 0.5.0
Relevant bit of my Ansible files look like this, following the Best
Practices section of the docs:
roles/jenkins-slave/tasks/main.yml
> roles/jenkins-slave/files/Dockerfile
My task in that main.yml looks like this:
- name: check or build jenkins-slave image
> docker_image: name=jenkins_java8 state=present
Note the lack of a path variable, which according to the docs is not a
required field.
When I run ansible-playbook, which then runs that task, I get this:
TASK: [jenkins-slave | check or build jenkins-slave image]

Specifying an absolute path for docker_image works, but that seems less
than ideal. I haven't found a relative path that works at all.
I'm admittedly a n00b to Ansible, so it's very likely I'm missing something
very basic here. Any kind of debugging help would be useful too - like how
could I trap the actual issued command to see what it thinks the path is?
Thanks,
