To get bash or SSH into a running docker container use the
docker exec command. The docker exec command will open up a new terminal with new instance of the current container.
So, run the below command to SSH into a running docker container in background:
sudo docker exec -it <container_id> /bin/bash
Example: Suppose your container id is b2e34e167a3 then use:
sudo docker exec -it b2e34e167a3 /bin/bash
