+h2(#docker-cleaner). Update docker-cleaner.json
+
+The @arvados-docker-cleaner@ program removes least recently used Docker images as needed to keep disk usage below a configured limit.
Create a file @/etc/arvados/docker-cleaner/docker-cleaner.json@ in an editor, with the following contents.
*Choosing a quota:* Most deployments will want a quota that's at least 10G. From there, a larger quota can help reduce compute overhead by preventing reloading the same Docker image repeatedly, but will leave less space for other files on the same storage (usually Docker volumes). Make sure the quota is less than the total space available for Docker images.
-Restart the service after updating the configuration file.

-*If you are using a different daemon supervisor,* or if you want to test the daemon in a terminal window, run @arvados-docker-cleaner@. Run @arvados-docker-cleaner --help@ for more configuration options.
