Welcome to the docker wiki!

We currently have to approaches for a docker image:

• https://github.com/geoserver/docker/pull/1
• https://github.com/geoserver/docker/pull/2

Comparison of the possibilities of the Dockerfile:

Feature	PR1 (terrestris)	PR2 (geosolutions)
Build image with custom GS version (docker will download WAR)	✔️ docker build -t geoserver:test --build-arg GEOSERVER_VERSION=2.18.2 .	✔️ docker build -t geoserver:test --build-arg GEOSERVER_WEBAPP_SRC=https://downloads.sourceforge.net/project/geoserver/GeoServer/2.18.2/geoserver-2.18.2-war.zip .
Build image with custom (local) WAR file (or zipped WAR)	✔️ docker build -t geoserver:test --build-arg GEOSERVER_WAR_SRC="./resources/geoserver.zip" .	✔️ docker build -t geoserver:test --build-arg GEOSERVER_WEBAPP_SRC=./resources/geoserver.zip .
The WAR source can either be a ZIP or a WAR file	✔️	✔️
Burn extensions to the image (docker will download JARs)	❌
Burn extensions to the image (local JARs/no download)	❌ (via build arguments) ✔️ (if JARs are included in a local WAR file build)
Control whether CORS should be enabled in the resulting image	✔️	❌
Allow to burn a local data dir to the resulting image	❌	✔️
Allow to add custom fonts to the resulting image	❌	❌

Comparison of the resulting Dockerimages:

Feature	PR1 (terrestris)	PR2 (geosolutions)
Image Size	762 MB	1,1 GB
Starts up with the default data directory	❌	✔️
Install extensions dynamically on startup (based on given configuration/env)	✔️ docker run -it --rm -p 8888:8080 --name geoserver -e DOWNLOAD_EXTENSIONS='true' -e STABLE_EXTENSIONS='wps,csw' terrestris/geoserver:2.19.0_GSIP-192	❌
