Dockerized GeoServer.

• Built on top of Docker's official tomcat image. Using tomcat:9-jre17 as base for versions 2.23.1 and above, and tomcat:9-jdk11 for versions below 2.23.1.
• Running tomcat process as non-root user.
• Separate GEOSERVER_DATA_DIR location (on /var/local/geoserver).
• Configurable extensions.
• Injectable UID and GID for better mounted volume management.
• CORS ready.
• Taken care of JVM Options.
• Automatic installation of Microsoft Core Fonts for better labelling compatibility.
• Custom geoserver deployment path
• docker health check

Latest versions with automated builds available on docker registry:

• latest, 2.25.0 (2.25.0/Dockerfile)
• 2.24.3 (2.24.3/Dockerfile)

Security patches for older versions:

• 2.23.5 (2.23.5/Dockerfile)
• 2.22.5 (2.22.5/Dockerfile) Latest with JDK 11
• 2.21.5 (2.21.5/Dockerfile)
• 2.20.7 (2.20.7/Dockerfile)
• 2.19.7 (2.19.7/Dockerfile)
• 2.18.7 (2.18.7/Dockerfile)

Other experimental dockerfiles (not automated build):

• oracle. Uses wnameless/oracle-xe-11g, needs ojdbc7.jar and setting up a database. See the run commands.
• h2-vector. Plays nicely with oscarfonts/h2:geodb, and includes sample scripts for docker-compose and systemd.
• ecw. Adding GDAL plugin with ECW support.

Think of them more as recipes or documentation rather than production-ready builds :)

Get the image:

docker pull oscarfonts/geoserver

Run as a service, exposing port 8080 and using a hosted GEOSERVER_DATA_DIR:

docker run -d -p 8080:8080 -v ${PWD}/data_dir:/var/local/geoserver oscarfonts/geoserver

• On build time, set the GEOSERVER_PATH arg to change the geoserver base path. It defaults to /geoserver.

The tomcat user uid and gid can be customized with CUSTOM_UID and CUSTOM_GID environment variables, so that the mounted data_dir and exts_dir are accessible by both geoserver and a given host user. Usage example:

docker run -d -p 8080:8080 -e CUSTOM_UID=$(id -u) -e CUSTOM_GID=$(id -g) oscarfonts/geoserver

To add extensions to your GeoServer installation, provide a directory with the unzipped extensions separated by directories (one directory per extension):

docker run -d -p 8080:8080 -v ${PWD}/exts_dir:/var/local/geoserver-exts/ oscarfonts/geoserver

You can use the build_exts_dir.sh script together with a extensions configuration file to create your own extensions directory easily.

Warning: The .jar files contained in the extensions directory will be copied to the WEB-INF/lib directory of the GeoServer installation. Make sure to include only .jar files from trusted sources to avoid security risks.

It is also possible to configure the context path by providing a Catalina configuration directory:

docker run -d -p 8080:8080 -v ${PWD}/config_dir:/usr/local/tomcat/conf/Catalina/localhost oscarfonts/geoserver

See some examples.

CORS is configured automatically in the servlet web.xml filters. If you have another component in front that already takes care of it you can disable it with the environment variable -e "GEOSERVER_CORS_ENABLED=false".

It is also possible to fine tune it for specific origins, methods, etc. with the following variables:

• GEOSERVER_CORS_ALLOWED_ORIGINS (cors.allowed.origins)
• GEOSERVER_CORS_ALLOWED_METHODS (cors.allowed.methods)
• GEOSERVER_CORS_ALLOWED_HEADERS (cors.allowed.headers)
• GEOSERVER_CORS_URL_PATTERN (filter-mapping url-pattern)
