It has to be noted that ansible-container is not a supported redhat product. So everything you see here is unsupported. If you want to use ansible to package containers look at the Ansible Playbook Bundle in OpenShift.
I thought it would be a good idea to see where ansible container is. My goal was to create a wordpress container backed by mariadb. Here is the github repo to my files: https://github.com/ldomb/ansible-container-wordpress.git
based on the documentation I was supposed to be able to build my project by simply running ansible-container build. This resulted in the following error
Collecting mysql-python (from -r /_ansible/build/ansible-requirements.txt (line 3))
Downloading MySQL-python-1.2.5.zip (108kB)
Complete output from command python setup.py egg_info:
sh: mysql_config: command not found
Traceback (most recent call last):

File "setup_posix.py", line 25, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
This is kind of weird as in my ansible role I am installing MySQL-python. It seems that this doesn’t matter.
A workaround to get this working is to use –use-local-python which uses the python you have on the system.
[root@host87 wordpress]# ansible-container build --use-local-python
After this builds correctly you can then run
[root@host87 wordpress]# ansible-container run
You can now go to http://localhost or http://ipwherethecontainersarerunning and should see the WordPress install page
If you want to push this image to OpenShift you can do the following (Be aware that I OpenShift was not able to run the image due to Error: InvalidImageName and Failed to apply default image tag:)
Login to OpenShift and create new project (be aware the project name has to match your ansible-container project name)
oc new-project wordpress
In OpenShift for ansible container to work the following needs to be done so that the user can access the registry:
oadm policy add-role-to-user system:registry bob oadm policy add-role-to-user admin bob -n wordpress oadm policy add-role-to-user system:image-builder bob oadm policy add-cluster-role-to-user cluster-admin bob
Now Bob can push images to openshift
then you can run as bob
oc whoami -t
now you can push the images to the registry
oc login --token $(oc whoami -t) host82.local.redhat-demo.com:8443
Then deploy the container to the OpenShift registry and create the build config
[root@host82 wordpress]# ansible-container --engine openshift deploy --push-to docker-registry-default.apps.local.redhat-demo.com --username bob --password $(oc whoami -t) --roles-path ./roles Parsing conductor CLI args.
