You'll need to copy all dependencies and if they're acquired through your package manager (apt-get), you'll leave dpkg's local database inconsistent. Copy just the files you need from the webots image using COPY -from=base.The webots image is not actually being used there. By default, the last stage in your Dockerfile will be the target (so, in your example, you're only actually using the ros2 image. This allows you to COPY from that stage specifying the -from option. When you have multiple FROM commands, you're not "inheriting" both of their contents into the same image - you're doing a multi-stage build. # Finally open a bash command to let the user interact # resolve a missing dependency for webots demo # new stuff added on top of niurover/ros2_foxy to assist with Webots + ROS2 #CMD # NOTE ignore this part of the Dockerfile
