Install Docker Engine on Ubuntu
如果你使用其他系统例如debian，请直接去官网查看，步骤稍微略有不同。
安装Docker
温馨提示：请记得先确认设置好Ubuntu的镜像源
懒惰的人可以直接通过以下命令安装+改源
bash <(curl -sSL https://linuxmirrors.cn/docker.sh)
升级
Update the apt package index and install packages to allow apt to use a repository over HTTPS:
sudo apt-get update
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
Add Docker’s official GPG key:
sudo mkdir -m 0755 -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
Use the following command to set up the repository:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
安装Docker Engine
Update the apt package index:
sudo apt-get update
Install Docker Engine, containerd, and Docker Compose.
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
测试并安装没用的镜像：
sudo docker run hello-world
添加Docker image的国内镜像 Add registry
登录阿里云镜像加速来获取你的镜像加速地址
只添加阿里源：
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://example.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
全部源添加：
查看是否有这个文件：/etc/docker/daemon.json
没有直接sudo nano新增
{
"registry-mirrors": [
"https://example.mirror.aliyuncs.com",
"https://hub-mirror.c.163.com",
"https://mirror.baidubce.com"
]
}
如果本身已有daemon.json,则应该如下示例
{
"log-opts": {
"max-size": "5m",
"max-file":"3"
},
"exec-opts": ["native.cgroupdriver=systemd"],
"registry-mirrors":[
"https://qwe67a1n.mirror.aliyuncs.com",
"https://hub-mirror.c.163.com",
"https://mirror.baidubce.com"
]
}
之后重新启动服务。
sudo systemctl daemon-reload
sudo systemctl restart docker
检查加速器是否生效
执行 $ docker info，(如果Docker还未配置用户，则需要用sudo) 如果从结果中看到了如下内容，说明配置成功。
Registry Mirrors:
