# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo http://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo
# sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# sudo yum-config-manager --add-repo http://mirrors.cloud.aliyuncs.com/docker-ce/linux/centos/docker-ce.repo

# Step 3: 添加 Docker yum 源
sudo sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce/docker-ce+' /etc/yum.repos.d/docker-ce.repo
# sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce/docker-ce+' /etc/yum.repos.d/docker-ce.repo
# sudo sed -i 's+download.docker.com+mirrors.cloud.aliyuncs.com/docker-ce/docker-ce+' /etc/yum.repos.d/docker-ce.repo

# Step 4: 更新缓存
sudo yum makecache

# Step 5: 安装Docker-CE
sudo yum -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# 启动 Docker 添加到开机自启
systemctl enable docker --now

# step 1: 更新系统到最新
sudo apt-get update
sudo apt update
sudo apt -y upgrade 

# step 2: 安装必要的一些系统工具
sudo apt -y install apt-transport-https ca-certificates curl software-properties-common

# step 3: 添加 Docker 密钥
curl -fsSL http://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg

# step 4: 添加 Docker 源
# 选项 1: 清华大学源
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" tee /etc/apt/sources.list.d/docker.list > /dev/null

# 选项 2: 阿里云源

# step 5: 更新 apt 缓存并安装 Docker
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# step 6: 启动 Docker
sudo systemctl enable docker

sudo systemctl start docker
