Geowebcache docker images, meant to be used with configurations/ambassadors.
Work in progress
###Data volume
Create a data volume to access the data:
docker create -v /cache --name=gwc-data busybox /bin/true
Now if you want to do something with the data (delete it, backup, copy, ...) start a (temporary) container to do your stuff.
docker run --rm -ti --volumes-from=gwc-data ubuntu? /bin/bash
Getting native JAI to work on jetty is difficult (impossible?) so we dont.
docker run -d --volumes-from=gwc-data -v $(pwd)/config:/config --name=gwc pdok/geowebcache:1.8.3-jetty-9.3-jre8
Jetty runs normally as jetty user (999), which might cause difficulties if the tiles are created with another user. To fix start with:
-e JAVA_OPTIONS="-Djetty.setuid.userName=username" and maybe do the same for jetty.setuid.groupName
The cache is configured at /cache and geowebcache.xml should be in /config/. If you don't set a config volume, a default is generated (GWC defaults).
Native JAI on tomcat does work. It might be faster, it might be not.
docker run -d --volumes-from=gwc-data -v $(pwd)/config:/config --name=gwc pdok/geowebcache:1.8.3-tomcat-8.5-jre8
docker run -d --volumes-from=gwc-data -v $(pwd)/config:/config --name=gwc mwengren/geowebcache:1.12-beta-tomcat-8.5-jre8
The cache is also configured at /cache and geowebcache.xml should be in /config/
From top dir:
docker build --rm -t pdok/geowebcache:1.8.3-jetty-9.3-jre8 1.8.3-jetty-9.3-jre8
docker build --rm -t pdok/geowebcache:1.8.3-tomcat-8.5-jre8 1.8.3-tomcat-8.5-jre8
