azure devops docker image prune does not work as expected

docker images created by an azure pipeline are not deleted correctly with sudo docker image prune -a.

The commands output tells that several images are untagged and deleted, however total reclaimed space: 0B. df confirms that there is not any reclaimed space

sudo docker system prune -a however works.

I also never had any problems with deleting docker images that I created with docker in the commandline

Solution

  • I am sorry it was not an azure devops problem but a problem with different versions of docker. On my local machine I used the one from the ubuntu packagemanagement. The devops agent run the one from the docker using ubuntus docker version solved the problem.
