MapCache
MapCache is a server that implements tile caching to speed up access to WMS layers. The primary objectives are to be fast and easily deployable, while offering the essential features (and more!) expected from a tile caching solution.
For more information, see MapCache repository: https://github.com/mapserver/mapcache
Run mapcache_seed
Seed google layer from config file:
docker run --rm -ti --volume=somewhere:/var/sig/tiles --volume=config.xml:/etc/mapcache/mapcache.xml camptocamp/mapcache:1.6 mapcache_seed -c /etc/mapcache/mapcache.xml -l google
Run mapcache
docker run --publish=8080:80 --volume=somewhere:/var/sig/tiles --volume=config.xml:/etc/mapcache/mapcache.xml camptocamp/mapcache:1.6
Run mapcache as non root user
docker run --user=www-data --publish=8080:8080 --volume=somewhere:/var/sig/tiles --volume=config.xml:/etc/mapcache/mapcache.xml camptocamp/mapcache:1.6
Tunings
You can set a few environment variables to tune the container:
MAX_REQUESTS_PER_PROCESS: Sets the limit on the number of connections that an individual child server process will handle. Can be used to work around leaks in mapcache. Defaults to 1000.SERVER_LIMIT: See https://httpd.apache.org/docs/2.4/mod/event.html (default=16)MAX_REQUEST_WORKERS: See https://httpd.apache.org/docs/2.4/mod/event.html (default=400)THREADS_PER_CHILD: See https://httpd.apache.org/docs/2.4/mod/event.html (default=25)MIN_SPARE_THREADS: See https://httpd.apache.org/docs/2.4/mod/event.html (default=75)
