Reason

too many inode?

To check inode info

df -i

How to fix

Kill processes. (This didn't work for me)

docker kill $(docker ps -qa)

Delete them.

docker rm -v $(docker ps -qa)

Delete all images.

docker rmi -f $(docker images -q)

@jklemm Check out this repo, it worked for me too https://github.com/chadoe/docker-cleanup-volumes

This didn't work on macOS.

I haven't tried this.

# remove stopped containers
docker rm $(docker ps -a -q)

# remove dangling images
docker rmi $(docker images -q --filter "dangling=true")
