I only use the Dockerfile I posted in the CI for rospy_message_converter and others, and its only purpose is to check that all dependencies are properly listed in the package.xml, build the package, and run the tests.

We are discussing the idea of adding something like osrf/ros:<distro>-devel, that would sort of mimic what we’ve been doing with osrf/ros2:devel, but be distro specific, where the common build tools, repos and dev environment are preconfigured, but with no ros distro packages installed:

Create a ROS 1 equivalent of osrf/ros2:devel
