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)

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

docker volume ls

docker volume rm your_volume
