Using ROS with Docker - Unable to set ROS_PACKAGE_PATH

I'm setting up a docker container for a project of mine which runs using ROS. I'm using rosmake and need to set the ROS_PACKAGE_PATH environment variable to include my own packages before calling rosmake. In the Dockerfile, I use ENV ROS_PACKAGE_PATH /foo:$ROS_PACKAGE_PATH

However when I run the container, the ROS_PACKAGE_PATH only contains /opt/ros/indigo/share:/opt/ros/indigo/stacks I need some help with this because without setting the ROS_PACKAGE_PATH I can't invoke a rosmake from inside the Dockerfile. Since the exact same method of setting environment variables is being used, successfully to set other non-ROS-related variables, I feel it might be more of a ROS issue than a Docker issue.

Thanks!

The problem was that the Dockerfile set the ROS_PACKAGE_PATH env variable for build time but it got reset during run time. I solved this by putting a script that set ROS_PACKAGE_PATH inside the container and calling it in the dockerfile using a RUN command before running rosmake through the Dockerfile itself. That worked beautifully.

I don't use ENV to set ROS_PACKAGE_PATH but export :

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/foo

Not working. Do you use this in your Dockerfile or after running the container? I am able to do it after running the container, but not in the Dockerfile. I used: RUN ["/bin/bash", "-c", "export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/foo"]

After running the container.

We use a script to set all environment variables.
