Why does “docker attach” hang?

Question

I can run an ubuntu container successfully:

# docker run -it -d ubuntu
3aef6e642327ce7d19c7381eb145f3ad10291f1f2393af16a6327ee78d7c60bb
# dock         


        

Answer 1

I just had a similar problem today and was able to fix it:

Here is what was happening for me:

docker-compose logs -f nginx
Attaching to laradock_nginx_1

Then it would hang there until I quit via CTRL-C: ^CERROR: Aborting.

docker ps -a showed that what SHOULD have been called laradock_nginx did not exist with that Image Name, so I figured I'd just remove and re "up" that container:

docker stop cce0c32f7556
docker rm cce0c32f7556
docker-compose up -d laradock_nginx

Unfortunately: ERROR: No such service: laradock_nginx

So I did a sudo reboot and then docker ps -a, but laradock_nginx still wasn't there.

Luckily, docker-compose up -d nginx then worked and docker-compose logs -f nginx now works.
