Pseudo-tty with Fig/Docker container

I need pseudo-tty and keep stdin open even if I am not attached to the container. In docker I can use this: docker run -i -t ubuntu /bin/bash

If I use this in fig:

test:
  image: ubuntu:14.04
  command: /bin/bash

Then I can't connect to the running docker container. Any idea?

Solution

  • With docker 1.3, there is a new command docker exec. This allows you to enter a running docker:

    docker exec -it <container-id> bash

    For older version of docker I would use the nsenter, a tool to connect to a running docker container.
