闪电云安装Docker

1. 安装 Docker（请先执行下面的命令）

sudo apt update
sudo apt install -y ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
​
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
​
sudo chmod a+r /etc/apt/keyrings/docker.gpg
​
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
  
sudo apt update
​
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

2. 验证 Docker 是否安装成功

sudo docker run hello-world

如果看到 Hello from Docker! 说明安装成功。

如果不成功请先添加国内镜像源

sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://docker.m.daocloud.io",
        "https://docker.imgdb.de",
        "https://docker-0.unsee.tech",
        "https://docker.hlmirror.com",
        "https://docker.1ms.run",
        "https://func.ink",
        "https://lispy.org",
        "https://docker.xiaogenban1993.com"
    ]
}

sudo systemctl daemon-reload
sudo systemctl restart docker
