|
|
|
dcgc
|
|
----
|
|
|
|
Remove old docker containers and docker images.
|
|
|
|
``dcgc`` will remove stopped containers and unused images that are older than
|
|
"max age". Running containers, and images which are used by a container are
|
|
never removed.
|
|
|
|
Maximum age can be specificied with any format supported by
|
|
`pytimeparse <https://github.com/wroberts/pytimeparse>`_.
|
|
|
|
Example:
|
|
|
|
.. code:: sh
|
|
|
|
dcgc --max-container-age 3days --max-image-age 30days
|
|
|
|
|
|
Prevent images from being removed
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
``dcgc`` supports an image exclude list. If you have images that you'd like
|
|
to keep around forever you can use the exclude list to prevent them from
|
|
being removed.
|
|
|
|
::
|
|
|
|
--exclude-image
|
|
Never remove images with this tag. May be specified more than once.
|
|
|
|
--exclude-image-file
|
|
Path to a file which contains a list of images to exclude, one
|
|
image tag per line.
|
|
|
|
|
|
|
|
dcstop
|
|
------
|
|
|
|
Stop containers that have been running for too long.
|
|
|
|
``dcstop`` will ``docker stop`` containers where the container name starts
|
|
with `--prefix` and it has been running for longer than `--max-run-time`.
|
|
|
|
|
|
Example:
|
|
|
|
.. code:: sh
|
|
|
|
dcstop --max-run-time 2days --prefix "projectprefix_"
|
