A geoserver docker image

This Dockerfile can be used to create images for all geoserver versions since 2.5.

• Debian based Linux
• OpenJDK 11
• Tomcat 9
• GeoServer
  • Support of custom fonts (e.g. for SLD styling)
  • CORS support
  • Support extensions
  • Support additional libraries

This README.md file covers use of official docker image, additional build and release instructions are available.

How to run official release?

To pull an official image use docker.osgeo.org/geoserver:{{VERSION}}, e.g.:

docker pull docker.osgeo.org/geoserver:2.24.1

All the images can be found at: https://repo.osgeo.org and the latest stable and maintenance version numbers can be obtained from https://geoserver.org/download/

Afterwards you can run the pulled image locally with:

docker run -it -p 80:8080 docker.osgeo.org/geoserver:2.24.1

Or if you want to start the container daemonized, use e.g.:

docker run -d -p 80:8080 docker.osgeo.org/geoserver:2.24.1

Check http://localhost/geoserver to see the geoserver page, and login with geoserver default admin:geoserver credentials.

IMPORTANT NOTE: Please change the default geoserver and master passwords.

For more information see the user-guide docker installation instructions.

How to mount an external folder for use as a data directory

To use an external folder as your geoserver data directory.

docker run -it -p 80:8080 \
  --mount src="/absolute/path/on/host",target=/opt/geoserver_data/,type=bind \
  docker.osgeo.org/geoserver:2.24.1

An empty data directory will be populated on first use. You can easily update GeoServer while using the same data directory.

How to start a GeoServer without sample data?

This image populates /opt/geoserver_data/ with demo data by default. For production scenarios this is typically not desired.

The environment variable SKIP_DEMO_DATA can be set to true to create an empty data directory.

docker run -it -p 80:8080 \
  --env SKIP_DEMO_DATA=true \
  docker.osgeo.org/geoserver:2.24.1

How to issue a redirect from the root ("/") to GeoServer web interface ("/geoserver/web")?

By default, the ROOT webapp is not available which makes requests to the root endpoint "/" return a 404 error. The environment variable ROOT_WEBAPP_REDIRECT can be set to true to issue a permanent redirect to the web interface.

How to download and install additional extensions on startup?

The startup.sh script allows some customization on startup:

• INSTALL_EXTENSIONS to true to download and install extensions
• STABLE_EXTENSIONS list of extensions to download and install
• CORS_ENABLED to true to enable CORS support. The following environment variables can be used to customize the CORS configuration.
  • CORS_ALLOWED_ORIGINS (default *)
  • CORS_ALLOWED_METHODS (default GET,POST,PUT,DELETE,HEAD,OPTIONS)
  • CORS_ALLOWED_HEADERS (default *)
  • CORS_ALLOW_CREDENTIALS (default false) Setting this to true will only have the desired effect if CORS_ALLOWED_ORIGINS defines explicit origins (not *)
• PROXY_BASE_URL to the base URL of the GeoServer web app if GeoServer is behind a proxy. Example: https://example.com/geoserver.

The CORS variables customize tomcat's web.xml file. If you need more customization, you can provide your own customized web.xml file to tomcat by mounting it into the container at /opt/config_overrides/web.xml.

Example installing wps and ysld extensions:

docker run -it -p 80:8080 \
  --env INSTALL_EXTENSIONS=true --env STABLE_EXTENSIONS="wps,ysld" \
  docker.osgeo.org/geoserver:2.24.1

The list of extensions (taken from SourceForge download page):

app-schema   gdal            jp2k          ogr-wps          web-resource
authkey      geofence        libjpeg-turbo oracle           wmts-multi-dimensional

excel        inspire         ogr-wfs       wcs2_0-eo

How to install additional extensions from local folder?

If you want to add geoserver extensions/libs, place the respective jar files in a directory and mount it like

docker run -it -p 80:8080 \
  --mount src="/dir/with/libs/on/host",target=/opt/additional_libs,type=bind \
  docker.osgeo.org/geoserver:2.24.1

How to add additional fonts to the docker image (e.g. for SLD styling)?

If you want to add custom fonts (the base image only contains 26 fonts) by using a mount:

docker run -it -p 80:8080 \
  --mount src="/dir/with/fonts/on/host",target=/opt/additional_fonts,type=bind \
  docker.osgeo.org/geoserver:2.24.1

Note: Do not change the target value!

How to enable a PostgreSQL JNDI resource?

To enable a PostgreSQL JNDI resource, provide the following environment variables:

• POSTGRES_JNDI_ENABLED to true
• POSTGRES_HOST
• POSTGRES_PORT (optional; defaults to 5432)
• POSTGRES_DB
• POSTGRES_USERNAME
• POSTGRES_PASSWORD
• POSTGRES_JNDI_RESOURCE_NAME (optional; defaults to jdbc/postgres)

In geoserver, you can then reference this JNDI resource using the name java:comp/env/jdbc/postgres (if using default).

How to use custom (tomcat) configuration files

This image provides default (tomcat) configurations that are located in the ./config/ subdir.

• context.xml (see/compare JNDI feature from above)
• server.xml (security hardened version by default)

In case you want to fully overwrite such a config file, you can do so by mounting it to the /opt/config_overrides/ directory of a container. The startup.sh script will then copy (and overwrite) these files to the catalina conf directory before starting tomcat.

Example:

docker run -it -p 80:8080 \
  --mount src="/path/to/my/server.xml",target=/opt/config_overrides/server.xml,type=bind \
  docker.osgeo.org/geoserver:2.24.1

How to use the docker-compose demo?

The docker-compose-demo.yml to build with your own data directory and extensions.

Stage geoserver data directory contents into geoserver_data, and any extensions into additional_libs folder.

Run docker-compose:

docker-compose -f docker-compose-demo.yml up --build
