Enter the Latest Container

Sometimes I want to see what is going on inside a running Docker container. With docker ps we can see the running containers. Using either the CONTAINER ID or NAMES we can enter the container:

docker exec --interactive --tty <container id/name> bash

In a workflow where containers are stopped, removed and a new container started it is cumbersome to update the above command with a new container id. Instead, we can get the last started container with the command docker ps -laq and use this with exec:

docker exec --interactive --tty $(docker ps -laq) bash
