My Docker crash course

Docker has taken the container world by storm. If you understood LXC from the previous post, Docker will feel like a polished toolkit built on similar ideas. This post gives you a quick start so you can begin running containers in minutes.

First, install Docker on your system. On Linux you can install it via your distribution’s package manager. On Windows and macOS you can download Docker Desktop from the official Docker website. Once installed, verify it works:

docker --version

If you see version information, you are ready.

Run your first container:

docker run hello-world

Docker will pull the image if it does not exist locally and then execute it. Congratulations. You just ran your first container.

To see running containers:

docker ps

To see all containers including stopped ones:

docker ps -a

To run an interactive Ubuntu container:

docker run -it ubuntu /bin/bash

You are now inside the container shell.

To exit:

exit

To stop a running container:

docker stop 

To remove a container:

docker rm 

To remove an image:

docker rmi 

Docker makes container management simple and repeatable. Once you start using it for development environments or microservices, you may wonder how you ever worked without it.

Happy Dockering.
