Install Docker On Raspberry Pi 4
20#Docker #RaspberryPi #Linux
Full steps can be found at https://i12bretro.github.io/tutorials/0475.html
01. Log into the Linux device
02. Execute the following commands in a terminal:
# update software repositories
sudo apt update
# install necessary packages for https apt calls
sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
# add docker GPG key
curl -fsSL https://download.docker.com/linux/raspbian/gpg | sudo apt-key add -
# add docker software repository
echo "deb [arch=armhf] https://download.docker.com/linux/raspbian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker-ce.list
# install docker
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io
# start docker service
sudo systemctl start docker
# enable docker service on startup
sudo systemctl enable docker
# create a docker group
sudo groupadd docker
# add the current user to the docker group
sudo usermod -aG docker $USER
03. To run a basic Docker container, run the following command in a terminal:
sudo docker run hello-world
04. Docker will download the hello-world container and execute it, displaying following output:
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.
(amd64)
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.
