Is it possible to start a shell session in a running container (without ssh)

Question

I was naively expecting this command to run a bash shell in a running container :

docker run \"id of running container\" /bin/bash

it look

Answer 1

EDIT: Now you can use docker exec -it "id of running container" bash (doc)

Previously, the answer to this question was:

If you really must and you are in a debug environment, you can do this: sudo lxc-attach -n Note that the id needs to be the full one (docker ps -notrunc).

However, I strongly recommend against this.

notice: -notrunc is deprecated, it will be replaced by --no-trunc soon.
