How do i ssh into a running conatiner

Question

Suppose, I have two containers and I wish to execute certain commands only on the first container. How do i ssh into a running container?

Answer 1

There is a docker exec command that can be used to connect to a container that is already running.

• Use docker ps to get the name of the existing container
• Use the command docker exec -it <container name> /bin/bash to get a bash shell in the container
• Generically, use docker exec -it <container name> <command> to execute whatever command you specify in the container.

Answer 2

To bash into a running container,you could use the following command:

docker exec -it container_name /bin/bash
