Make QGIS Server URL configurable via ENV and read project names from database

[danceb]

To use another QGIS Server url than http://qwc-qgis-server/ows/ this should also be configurable via ENV.

Furthermore I added the possibility to read the WMS service names from a database via mounting a pg_service.conf file. So in this case not all project names has to be listed in preseed_services.txt.

Thanks!

I came across this. Besides, that the PR is still open, just a question:

For what is the code in [1] needed? as the ENV are already specified within the Dockerfile at [2], is there a need to export them again to a local file and read them out of this file?

Indeed either I forgot to click on merge or the mouse button failed. Regarding your question: I think to remember that chronjobs start with a clean environment

Uh, in this case the new ENV DEFAULT_QGIS_SERVER_URL has to be exposed there aswell:

cat > $HOME/.cron_env <<EOF
export QGS_EXT=${QGS_EXT}
export FCGI_INSTANCES=${FCGI_INSTANCES}
export SLEEP_INTERVAL=${SLEEP_INTERVAL}
export DEFAULT_QGIS_SERVER_URL=${DEFAULT_QGIS_SERVER_URL}
EOF

Right, done in a3ca37c

I am sorry, it's shame, that I missed this one... There is another new ENV PG_DB_SCHEMA for reading the QGIS projects from data base ...

[manisandro]

Added this one as well: 78098cc

I admit it, I have done the tests with user request only and not via crontab... So I have found another one ...

export PGSERVICEFILE=${PGSERVICEFILE} has to be added aswell, otherwise the pg service is not found within the psql commands.

Furthermore L25 of the Dockerfile [1] isn't needed indeed, as the ENV CONFIG_DB_URL is not used within the shell scripts.
I think I introduced this to make the service name configurable, but choosed to set it to qgisprojects as it is used in the config service aswell.
The comment in [2] could be changed to somethin like:
# Postgres service configuration file including a [qgisprojects] service to read QGIS project files from database.

This should be everything until now ... ;-)

If you have those changes locally, could you submit a PR?
