#配置docker的yum地址
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

#更新源
sudo yum makecache fast

# 安装最新版本
yum -y install docker-ce docker-ce-cli containerd.io

# 或者安装指定版本

1. 查看版本
yum list docker-ce --showduplicates | sort -r
yum list docker-ce-cli --showduplicates | sort -r
yum list containerd.io --showduplicates | sort -r

2. 指定版本安装
sudo yum install -y docker-ce-24.0.5 docker-ce-cli-24.0.5 containerd.io-1.6.9

# 启动&开机启动docker
systemctl enable docker --now

# docker加速配置
sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'

解决 docker: Error response from daemon: Get “https://registry-1.docker.io/v2/“: net/http:

编辑Docker的配置文件 /etc/docker/daemon.json，添加或修改如下内容，以使用国内的镜像加速器：
修改为下面的源

{
    "runtimes": {
        "nvidia": {
            "args": [],
            "path": "nvidia-container-runtime"
        }
    },
    "registry-mirrors": [
        "https://docker.registry.cyou",
        "https://docker-cf.registry.cyou",
        "https://dockercf.jsdelivr.fyi",
        "https://docker.jsdelivr.fyi",
        "https://dockertest.jsdelivr.fyi",
        "https://mirror.aliyuncs.com",
        "https://dockerproxy.com",
        "https://mirror.baidubce.com",
        "https://docker.m.daocloud.io",
        "https://docker.nju.edu.cn",
        "https://docker.mirrors.sjtug.sjtu.edu.cn",
