Thanks Aleks,

Is this deleting images on your nodes or also on your

As far as I have seen only in the registy not on the nodes.
That's the reason why we afterwards execute a

ansible -m shell -a 'docker rmi $(docker images -q)' all

And for example:

oadm prune images --keep-younger-than=60m

Will this only delete images images older than 60m which aren't used?
Or wil this also delete images which are used (maybe only on the node
but not out of the registry?)

Well due to the fact hat I'm not using such option you can try it by your own as long as you don't add ' --confirm ' to the command

Do you have tried this way?


After wards we have run

docker rmi $(docker images -q)

on every node.

I'm not sure if the last step is still necessary in the current
