Raspberry Pi 4B-Install Docker

Raspberry Pi 4B-Install Docker

The installation tutorial on the Docker official website has explained that you can only install Docker on the Raspberry Pi using a script installation method, so the next introduction is to install Docker on the Raspberry Pi using a script

Docker installation

Obtain the installation script (community version)

curl -fsSL https://get.docker.com -o get-docker.sh

Execute the installation script

sudo sh get-docker.sh

After the installation is successful, as shown in the figure, sometimes the installation does not repeat several timessudo sh get-docker.sh

Run Docker

Basic command

# Docker开机自启
sudo systemctl enable docker
# 启动Docker
sudo systemctl start docker
# 查看当前Docker版本
sudo docker version
# 重启Docker
sudo systemctl restart docker

Modify the mirror source

The Docker image source is used to download the image. By default, the download image of a foreign country will be slower, and it will be faster to switch to a domestic image.

Mirror image	connection
HKUST Mirror	https://docker.mirrors.ustc.edu.cn/
NetEase	https://hub-mirror.c.163.com/

#这里使用的是 科大镜像
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    
    
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/"]
}
EOF
#重新加载配置文件
sudo systemctl daemon-reload
#重新启动docker
sudo systemctl restart docker

Execute hello-world

sudo docker run hello-world

Seeing the following content indicates that Docker can be used normally

Uninstall

#卸载Docker Engine，CLI和Containerd软件包
sudo apt-get purge docker-ce docker-ce-cli containerd.io
#主机上的映像，容器，卷或自定义配置文件不会自动删除，要手动删除所有图像，容器和卷执行如下
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
