Commands You Will Learn

docker logs <container-name/container-id> – list everything your container has written to the Standard Input, Standard Outpu or Standard Error(STDIN/STDOUT/STDERR).

docker exec <container-name/container-id> <command-to-be-executed-inside-the-container> – execute a command inside your container (e.g., docker exec 0099887 ls). Important to note here, is that, this command needs to be available in the container’s file system.

docker exec --tty --interactive <container-name/container-id> sh – create an interactive shell that is similar to an SSH connection to a server.
