SUMMARY

Updated version of prebaking conductors onto current dev w/ some bugfixes. Currently python setup.py prebake bakes all images, but I've found some flakiness with Jessie builds.

Specific Jessie error:

@ryansb what's the status here?

What is the ansible-container argument to disable this? I am running on ARM and the the pre-built images will not work.

I don't see a disable option. The docs state that you can build your own: http://docs.ansible.com/ansible-container/conductor.html

Referencing the template conductor Dockerfile provides a roadmap.

I forgot... You can build a conductor locally using the following command:

$ python ./setup.py prebake --distros $BASE_DISTRO --debug

You can see a full example in our .travis.yml file. You'll need to run Ansible Container from source, so that you have a local copy of the project and access to setup.py.

Replace BASE_DISTRO with centos:7, ubuntu:precise, or whatever distro:tag you're needing.

Hope this helps.
