There are many docker images who could be delete ?

(Jeff Atwood) #6

I believe the latest Docker has an official command to clean up @falco can you share it here?

(Rafael dos Santos Silva) #7

You can run docker system prune to remove all old stuff from Docker.


On my server docker system prune doesn’t exist (who knows) but instead I could do:

  1. list all images docker images
  2. remove them with docker rmi INSERT_IMAGE_ID_HERE

That system prune method is only available with more recent versions of Docker. The way you describe is the older manual way. That older way still works, it just is a bit more complicated.
