-# 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.
-# If your deployment uses a Python 3 Software Collection, uncomment the
-# ExecStart line below, and delete the following one:
-# ExecStart=scl enable python33 "python3 -m arvados_docker.cleaner --quota 20G"
-ExecStart=python3 -m arvados_docker.cleaner --quota 20G
