[Feature] Install & configure fake xserver to print

[jancelin]

xvfd available in the jancelin/docker-qgis-server:2.18LTR !!! finally took the time to do it...
But I can't print the background maps as google-satellite or osm-mapnik :(

Can you test?

[jlstanus]

To activate the the xserver :

1. List the containers docker ps and get the id of the qgis server (not lizmap) container. For exemple container id 09458996bc1c
2. Go into the container command line docker exec -ti 09458996bc1c bash
3. Follow steps here
4. Leave the container exit
5. docker-compose restart. Opening the project should give an error
6. go back in the qgis server container and execute the following command line Xvfb :99 -screen 0 1024x768x24 -ac +extension GLX +render -noreset &

Always not possible to print pDF but PNG, SVG too

Maybe, due to HTTS use?

I catch nothing in the error.log

Thanks jl
Could be a PR in docker-qgis-server in my opinion !

[jlstanus]

;-)
This is happening in the debian:jessie image, not the lizmap one. I don't know the best way to modify only the debian image. But interested to learn @jancelin

[kikislater]

Basically without testing :

1 - in Dockerfile here : https://github.com/jancelin/docker-lizmap/blob/master/Dockerfile
You could add xvfb in line 8 before \

2 - in fcgid.conf : https://github.com/jancelin/docker-lizmap/blob/master/files/fcgid.conf between line 14 and 15

# Pass display number to QGIS MapServer instances
 FcgidInitialEnv DISPLAY ":99"

3 - Add a new file in file folder : https://github.com/jancelin/docker-lizmap/tree/master/files called
xvfb.service with the following

[Unit]
Description=X Virtual Frame Buffer Service
After=network.target

[Service]
ExecStart=/usr/bin/Xvfb :99 -screen 0 1024x768x24 -ac +extension GLX +render -noreset &

[Install]
WantedBy=multi-user.target

Source : https://gist.github.com/ypandit/f4fe751bcbf3ee6a32ca

4 - Add this line at line 18 in setup.sh here : https://github.com/jancelin/docker-lizmap/blob/master/files/setup.sh
mv /home/files/xvfb.service && chmod +x /etc/systemd/system/xvfb.service && systemctl enable xvfb.service && systemctl start xvfb.service

[jlstanus]

You are right on the command lines but not on the repository.
This has to be done in the docker-qgis-server repository not here

[kikislater]

Yes agree sorry !
Could be adapt quickly ...

[jlstanus]

yes ;-)

[kikislater]

Do you want to do it ?
If not I could ;-)

[jlstanus]

You can if not i ll do it later. It's your proposition. 😜 Cordialement, Jean-Louis Stanus
