QGIS server Docker image for QWC.
Requests to /ows/<project> are mapped to /data/<project>.qgs.
The FCGI configuration of the QGIS Server can be configured by setting some environment variables.
Here is a list of all environment variables that can be currently set and their default values. The list also contains information about which application the environment variables configure.
See QGIS Server documentation for more information about QGIS Server specifc environment variables.

Other QGIS Server settings that are used:
- QGIS_CUSTOM_CONFIG_PATH: "/var/lib/qgis"
- QGIS_AUTH_DB_DIR_PATH: "/var/lib/qgis"
- QGIS_OPTIONS_PATH: "/etc"
- QGIS_PLUGINPATH: "/usr/share/qgis/python/plugins"
- QGIS_SERVER_API_RESOURCES_DIRECTORY: "/usr/share/qgis/resources/server/api"
- QGIS_SERVER_CACHE_DIRECTORY: "/.cache"
- PGSERVICEFILE: "/etc/postgresql-common/pg_service.conf"
You can pass arbitrary environment variables to FCGI by setting FCGID_EXTRA_ENV to a comma-separated list of additional variables,
and then setting the variables itself. This is useful for instance for qgis server plugins.
Example:
FCGID_EXTRA_ENV=FOO,BAR
FOO=foo_val
BAR=bar_val
To add additional fonts, mount your font directoy to /usr/local/share/fonts.
The default locale is en_US. You can choose a different locale by setting the LOCALE environment variable to lang_COUNTRY (i.e. de_CH).
Some projections may need additional datum grids for best accuracy. These are available at https://cdn.proj.org/. Please mount these files below /usr/share/proj.
Mount a file with contents
[proxy]
proxyEnabled=true
proxyType=HttpProxy
proxyHost=myproxyhost
proxyPort=8080
to /etc/QGIS/QGIS3.ini.
QGIS Server can load QGIS projects directly from a postgresql database.
This image is preconfigured to load projects from the database when QGIS Server is called as follows:
http://localhost:8001/ows/pg/<schema>/<projectname>
It will use the qgisprojects postgresql service connection, which must be defined in the pg_service.conf which is mounted into the qwc-qgis-server container.
You can monitor the n last lines of the QGIS Server logs via /logs?n=<n>, i.e. http://localhost:8001/logs?n=100.
