Ufo
comes with a handy command to clean up old images that ufo generates. Ufo
only deletes images from the docker daemon and does not remove any images from any registry. To use it you pass the base portion of the image name to the command.
Say you currently have these images:
tongueroo/demo-ufo:ufo-2016-10-15T19-29-06-88071f5 tongueroo/demo-ufo:ufo-2016-10-16T19-29-06-88071f5 tongueroo/demo-ufo:ufo-2016-10-17T19-29-06-88071f5 tongueroo/demo-ufo:ufo-2016-10-18T19-29-06-88071f5
To clean them up and keep the 3 more recent:
$ ufo docker clean tongueroo/demo-ufo Cleaning up docker images... Running: docker rmi tongueroo/demo-ufo:ufo-2016-10-15T19-29-06-88071f5
This will remove tongueroo/demo-ufo:ufo-2016-10-15T19-29-06-88071f5.
By default the clean command keeps the most 3 recent docker images. If you would like to override this setting you can use the --keep
option. Example:
ufo docker clean tongueroo/demo-ufo --keep 5
