# 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
**IMPORTANT NOTE:** Please change the default geoserver master password! The default masterpw is located in this file (within the docker container): `/opt/geoserver_data/security/masterpw/default/masterpw`
## How to build?
`docker build -t {YOUR_TAG} .`
## How to quickstart?
Build the image as described above, then:
`docker run -it -p 80:8080 {YOUR_TAG}`
or if you want to start the container daemonized:
`docker run -d -p 80:8080 {YOUR_TAG}`
Check http://localhost/geoserver to see the geoserver page and login with geoserver defaults `admin:geoserver`
## How to build a specific GeoServer version?
`docker build --build-arg GS_VERSION={YOUR_VERSION} -t {YOUR_TAG} .`
## How to build with custom geoserver data?
`docker build --build-arg GS_DATA_PATH={RELATIVE_PATH_TO_YOUR_GS_DATA} .`
**Note:** The passed path **must not** be absolute! Instead, the path should be within the build context (e.g. next to the Dockerfile) and should be passed as a relative path, e.g. `GS_DATA_PATH=./my_data/`
## Can I build a specific GS version with custom data?
Yes! Just pass the `--build-arg` param twice, e.g.
`... --build-arg GS_VERSION={VERSION} --build-arg GS_DATA_PATH={PATH} ...`
## How to build with additional libs/extensions/plugins?
Put your `*.jar` files (e.g. the WPS extension) in the `additional_libs` folder and build with one of the commands from above! (They will be copied to the GeoServer `WEB-INF/lib` folder during the build.)
**Note:** Similar to the GeoServer data path from above, you can also configure the path to the additional libraries by passing the `ADDITIONAL_LIBS_PATH` argument when building:
`--build-arg ADDITIONAL_LIBS_PATH={RELATIVE_PATH_TO_YOUR_LIBS}`
## How to add additional libs using an existing docker image?
If you want to add geoserver extensions/libs by using a mount, you can add something like
```
--mount src="/dir/with/libs/on/host",target=/opt/additional_libs,type=bind
```
## 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, you can add something like
```
--mount src="/dir/with/fonts/on/host",target=/opt/additional_fonts,type=bind
```
to your `docker run` command.
**Note:** Do not change the target value!
## How to watch geoserver.log from host?
`docker exec -it {CONTAINER_ID} tail -f /opt/geoserver_data/logs/geoserver.log`
## How to use the docker-compose demo?
`docker-compose -f docker-compose-demo.yml up --build`
