Running Docker
To start the docker daemon run:
sudo systemctl start docker
To check everything is working, run the docker info:
user@imx8mpnavq:~$ sudo docker info Client: Context: default Debug Mode: false Server: Containers: 3 Running: 0 Paused: 0 Stopped: 3 Images: 1 Server Version: 20.10.21 ... Insecure Registries: 127.0.0.0/8 Live Restore Enabled: false
Running “Hello, world!”
Pull and run the first container, hello-world:
sudo docker run hello-world
Post-install Configuration
If you want to run docker without root privileges, add user to the docker group:
sudo usermod -aG docker $USER
After you log out and log back, you can run docker commands without sudo:
user@imx8mpnavq:~$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
