[SOLVED] Running Eclipse inside Docker

[Armin@netPI]

As expected the missing graphical base system is the root cause of your problem.

For a test I loaded a Desktop image on my netPI from here https://cloud.docker.com/u/hilschernetpi...sktop-hdmi.

After I started a container of the image I opened a console on the screen under the default user "testuser" and called the commands:

Code:

> sudo apt-get update
> sudo apt-get install eclipse
> eclipse

Eclipse was starting right away and I was able to click the Eclipse Icons with my mouse.

So your choice using raspbian/stretch as base image is not feasible. I would write a Dockerfile like this instead:

Code:

FROM hilschernetpi/netpi-desktop-hdmi
USER testuser
RUN sudo apt-get update
RUN sudo apt-get install eclipse

This sequence combines both Desktop and Eclipse environment.

And starting Eclipse itself in a Dockerfile (like you did) does not make sense at all. A Dockerfile creates an offline image and in an image you don't want to start Eclipse ... you want to start Eclipse when a container is started from the image at runtime, right? So start it when the container is running on your netPI using the console.
