前言
- TencentOS Server 3.1(与 CentOS 8用户态完全兼容,配套基于社区5.4 LTS 内核深度优化的 tkernel4版本)
安装 docker-ce
-
先卸载老版本,没有老版本的跳过
yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-engine
-
安装 yum-utils
yum install -y yum-utils
-
添加docker-ce.repo
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
PS:更换 Docker CE 仓库镜像 (也可以不更换)
-
安装最新版本
yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
-
查看版本
docker -v
-
启动docker
systemctl start docker
-
运行 hello-world 镜像
docker run hello-world
设置Docker Hub 镜像缓存
-
设置 Docker Hub 镜像缓存
对于使用 systemd 的系统(Ubuntu 16.04+、Debian 8+、CentOS 7), 在配置文件 /etc/docker/daemon.json 中加入:
{ "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/"] }
重新启动 dockerd:
systemctl restart docker
-
检查Docker Hub 镜像缓存是否生效
如果从结果中看到了如下内容,说明配置成功。
