# Janitor
|
|
|
|
### Topology
|
|
|
|
A Janitor instance will be started on every host that does not match the
|
|
scheduling rule (default is `janitor.exclude=true`).
|
|
|
|
### Operation
|
|
|
|
This will run a task daily (by default) that will delete any unused
|
|
image, and any orphaned volume. The rancher container images are excluded
|
|
from the list of images to clean up, and you can add your own containers to
|
|
the exclude list if you wish.
|
|
|
|
This will halp to prevent the /var/lib/docker filesystem from filling up
|
|
with old and unused container images.
