ROS (Melodic) + Docker: rosrun not found

edit

Hi there,

I am currently trying to run ROS Melodic on Docker to build the rosserial_arduino libraries for Arduino. Therefore I need to run rosrun rosserial_arduino make_libraries.py in the Docker container. However I get a rosrun: command not found, despite sourcing the setup.bash. Here is my Dockerfile:

FROM osrf/ros:melodic-desktop-full-bionic as builder_base
SHELL ["/bin/bash", "-c"]
COPY . .
RUN apt-get update && apt-get install -y \
    ros-melodic-rosserial-arduino \
    ros-melodic-rosserial \
    python-rosdep \
    python-rosinstall \
    python-rosinstall-generator \
    python-wstool \
    build-essential \
    && rm -rf /var/lib/apt/lists/

RUN echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
RUN source ~/.bashrc
WORKDIR /arduino
RUN rosrun rosserial_arduino make_libraries.py

I run this on Ubuntu 19.04.

Any ideas why I get this error and how to solve it?

Thanks in advance!
