Pulp

The logs for the single container display the following traceback. This is due to pulp storing symlinks in /var/lib/pulp/assets/. The symlinks for drf-yasg are now broken because pulpcore no longer uses that package.

FileNotFoundError: [Errno 2] No such file or directory: '/var/lib/pulp/assets/drf-yasg/immutable.min.js'

This issue can be worked around by removing the 'assets/drf-yasg' directory from the pulp storage directory on the host machien.
