[GRASS-dev] Docker image based on Alpine Linux with GRASS GIS 7.7.git and wxGUI

[Markus Neteler]

Hi,

I am trying to create a docker image with wxGUI.

After hours of attempts (since Alpine does not offer the wxPython
package, so it needs to be pip installed in the Dcokerfile) I got it
build:

https://hub.docker.com/r/neteler/docker-alpine-grass-gis-gui

# fetch image
docker pull neteler/docker-alpine-grass-gis-gui

# run image
docker run -i -t --rm -v $(pwd):/tmp -v /tmp/.X11-unix:/tmp/.X11-unix
-e uid=$(id -u) -e gid=$(id -g) -e DISPLAY=unix$DISPLAY --name grass77
neteler/docker-alpine-grass-gis-gui grass77 --gui
Starting GRASS GIS...

As you see - no GUI while g.gui is there!?

# interactive test
docker run -i -t --rm -v $(pwd):/tmp -v /tmp/.X11-unix:/tmp/.X11-unix
-e uid=$(id -u) -e gid=$(id -g) -e DISPLAY=unix$DISPLAY --name grass77

Looks ok.

I suspect some missing lib on my Alpine image but have no idea which one.

Does anyone has an idea?

thanks,
