Docker troubleshooting

Use docker command to see if all required containers are up and running:

$ docker ps -a

Check online logs of ssh container:

$ docker logs ssh

Attach to running ssh container (to detach the tty without exiting the shell, use the escape sequence Ctrl+p + Ctrl+q):

$ docker attach ssh

Sometimes you might just want to review how things are deployed inside a running container, you can do this by executing a bash shell through docker's exec command:

docker exec -i -t ssh /bin/bash

History of an image and size of layers:

docker history --no-trunc=true million12/ssh | tr -s ' ' | tail -n+2 | awk -F " ago " '{print $2}'
