1. 卸载 podman
yum -y erase podman buildah
2. 安装依赖包
yum install -y yum-utils device-mapper-persistent-data lvm2
3. 配置镜像源
yum config-manager --add-repo=https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
4. Docker安装
(1) 安装 containerd
yum install -y containerd.io --allowerasing
(2) 安装 Docker Engine-Community
yum install -y docker-ce-3:24.0.6-1.el9
systemctl enable docker
systemctl start docker
5. 配置镜像加速器
镜像文件一般都很大,如果觉得镜像下载比较慢可配置镜像加速器。
阿里云镜像加速器获取地址: https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors
直接完整复制以下命令执行:
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://xxxx.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
