ISSUE TYPE
SUMMARY

Versions of ruamel.yaml >=0.15.52 cause ansible-container build to fail with 'CommentedMap' is not JSON serializable error. See issue #958

To reproduce the issue:

$ virtualenv venv
$ source venv/bin/activate
$ git clone https://github.com/ansible/ansible-container.git
$ pip install -e ansible-container
$ ansible-container init
$ ansible-container build

Before the change:

$ ansible-container build

Until new version of ansible-container is released we fixed this by adding the same line to ansible-requirements.txt

ruamel.yaml>=0.15.34,<=0.15.51

@linkebon I recommend trying to reach one of 3 maintainers : https://pypi.org/project/ansible-container/

@j00bar seems busy at a moment. Not sure about @ryansb Only they can release new version on a pypi.
