GeoWebCache is a Java web application used to cache map tiles coming from a variety of sources such as OGC Web Map Service (WMS). It implements various service interfaces (such as WMS-C, WMTS, TMS, Google Maps KML, Virtual Earth) in order to accelerate and optimize map image delivery. It can also recombine tiles to work with regular WMS clients.

To start GeoWebCache:
$ docker run --rm -d -p 8080:8080 --name gwc weeix/geowebcache
You can test it by visiting http://localhost:8080/gwc or http://host-ip:8080/gwc in a browser.
To mount a directory from your host to the container's local storage:
$ docker run --rm -d -p 8080:8080 -v "$(pwd)"/data:/usr/local/tomcat/temp/geowebcache --name gwc weeix/geowebcache
Then visit http://localhost:8080/gwc or http://host-ip:8080/gwc in a browser to generate geowebcache.xml.
After editing geowebcache.xml, you can reload the configuration by visiting http://localhost:8080/gwc/demo or http://host-ip:8080/gwc/demo then press the Reload TileLayerConfiguration button.
The default administrator's username/password is geowebcache/secured. However, you can change them by using environment variables.
For more information on how to use GeoWebCache, please see the user manual.
The following environment variables could be used:
- GWC_USER for changing the default administrator's username e.g.
-e GWC_USER='bob' - GWC_PASS for changing the default administrator's password e.g.
-e GWC_PASS='mypassword' - JAVA_OPTS for passing JVM parameters e.g.
