Docker FATAL: could not write lock file "postmaster.pid": No space left on device

Question

postgres:9.5

I try rebooting,

docker-compose build --no-cache

delete image and container and build again

I have many proyects and anybody starts, keeps the same configuration... Mac osx Sierra

Apparently the containers were not deleted well, I tried with this and after rebuild works ok.

# Delete all containers
docker rm $(docker ps -a -q)
# Delete all images
docker rmi $(docker images -q)

Answer 1

If you do not have any critical data you can blow away the docker volume.

docker volume ls

docker volume rm your_volume

Answer 2

If you're coming here from Google and finding that multiple containers are complaining of Disk space, the issue may be that your local Docker installation has maxed out its disk image size. This is configurable in Docker for Mac. Here are the instructions to change that disk image size.
