Bridge between ROS Melodic and ROS2 Galactic

Hi, I am pretty much new to docker and its abilities.

I am wondering if it is possible to set up a docker image including ROS2 Galactic and run it on Ubuntu 18.04 which already has a ROS Melodic installed and finally set up a rosbridge between them. In the OSRF docker hub, all ros1bridge containers have ROS2+Noetic (simply because both support ubuntu 20.04), but I would like to have ROS2+Melodic.

Short answer? maybe.

ROS 2 Galactic officially targets Ubuntu 20.04. We don't regularly run any builds or tests and we don't distribute any pre-built binaries for any other version of Ubuntu. That doesn't mean that we've consciously broken compatibility with 18.04, but I wouldn't be surprised to hear that you need to make changes to the sources to make it work there.

This has little to do with the capabilities of Docker and more to do with the differences between Ubuntu releases, and the decision to target only one of them under each ROS distribution.
