Container Support

In a default pulplift environment, content_host is not included in the pulp_settings. In this environment, retrieving the task with a created_resource of a distribution fails.

This is covered by the functional tests, which fail out of the box on pulplift.

Workaround¶

Append `CONTENT_HOST=localhost:24816` to `/etc/pulp/settings.py`, and restart the services. Tests pass.
