This document mainly introduces the installation and use of Docker. You will learn how to install Docker on Khadas SBC and test if the installation is successful.

Add docker source.

$ sudo add-apt-repository \
	"deb [arch=arm64] https://download.docker.com/linux/ubuntu \
	$(lsb_release -cs) \
	stable"

$ sudo apt-get update

$ docker run hello-world

If you see the following messages, it means that Docker has been setup correctly:

$ docker run hello-world
 
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
255483503861: Pull complete 
Digest: sha256:4b8ff392a12ed9ea17784bd3c9a8b1fa3299cac44aca35a85c90c5e3c7afacdc
Status: Downloaded newer image for hello-world:latest
 
Hello from Docker!
This message shows that your installation is working correctly.
 
To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (arm64v8)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.
 
To try something more ambitious, you can run a Ubuntu container with:
 $ docker run -it ubuntu bash
