Follow these steps to install Docker on supported Linux systems.
Execute this terminal command: $ sudo apt-get update $ sudo apt-get upgrade $ curl -fsSL get.docker.com -o get-docker.sh && sh get-docker.sh
- Add the ubuntu user, which is what you are currently, to the Docker group. This will allow you to avoid needing super user (sudo) to run the Docker command, as you can see in the following code:
$ sudo usermod -aG docker $USER
- Log out and back in again for the change to take effect.
- Test the install with a quick hello-world run, as you can see here:
Hello from Docker! This message shows that your installation appears to be 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 an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
