1、配置软件源

1.1、下载repo配置文件

curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo

或者

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

1.2、修改安装源为国内地址

sed -i 's#https://download.docker.com#https://mirrors.tuna.tsinghua.edu.cn/docker-ce#' /etc/yum.repos.d/docker-ce.repo

1.3、docker软件源不支持openEuler，可以配置centos的，因为跟centos类似

sed -i 's#$releasever#7#g' /etc/yum.repos.d/docker-ce.repo

完整内容：

/etc/yum.repos.d/docker-ce.repo

2、安装

2.1、不指定版本，默认安装最新版本（不推荐）

yum install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

2.2、指定版本

2.2.1、查看可以安装的版本

yum list docker-ce --showduplicates | sort -r

2.2.2、安装指定版本

yum install docker-ce-24.0.7 docker-ce-cli-24.0.7 docker-ce-rootless-extras-24.0.7 containerd.io docker-buildx-plugin docker-compose-plugin -y

2.2.3、修改docker配置文件：/etc/docker/daemon.json

cat > /etc/docker/daemon.json << "EOF"
{
  "data-root": "/data/docker",
  "registry-mirrors": [
     "https://registry.hub.docker.com",
     "https://mirror.baidubce.com",
     "https://hub-mirror.c.163.com",
     "https://docker.mirrors.ustc.edu.cn",
      "https://docker.xuanyuan.me",
      "https://docker.1ms.run",
      "https://docker.1panel.live"
  ],
  "log-opts": {
    "max-size": "10m",
    "max-file":"3"
  },
  "storage-driver": "overlay2",
  "exec-opts": ["native.cgroupdriver=systemd"]
}

EOF

说明： 请根据实际情况配置以下参数

data-root：数据目录

registry-mirrors：常用的 Registry 代理服务器

log-opts： Log 文件最容量设置为 50MB，默认是 10MB（一定要根据实际需求设置，过大过小都不合适，如不确定请使用默认值）

exec-opts： 配置了 cgroup driver 使用 systemd，适用于 Kubernetes 场景，Docker 默认使用 cgroupfs

或者指定域名拉取，如使用轩辕镜像拉取

docker pull docker.1ms.run/redis:7.2.11

2.3、启动

systemctl start docker

设置开机自启

systemctl enable docker --now
