Running the Client

On the Same Host as the Server

In order to connect to the docker server over the Unix socket, the user running the client must have permissions to do so:

[testuser@docker-server ~]$ ls -al /var/run/docker.sock
srw-rw----. 1 root docker 0 Apr 25 16:00 /var/run/docker.sock

One way to do that is to make the user a member of "docker" group:

usermod -G docker testuser

Image Introspection and Manipulation

Explore an Image

If the image has a shell, it can be run in interactive mode and explored:

 docker run --rm -it <image-id|name> bash|sh

While the container is running, the image can be exported into a TAR file system with docker export and explored off-line.

Determine the Command that Launches the Process to Be Executed in the Container

docker inspect --format '{{.Config.Cmd}}' <image-id>
