安装 Docker（使用国内源）

一、安装Docker-ce

1、下载阿里云的repo源

[root@localhost ~]# yum install yum-utils -y && yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo  &&  yum makecache

# 尝试列出 docker-ce 的版本

[root@localhost ~]# yum list docker-ce --showduplicates | sort -r

2、安装 Docker-ce

[root@localhost ~]# yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

4、启动Docker

[root@localhost ~]# systemctl restart docker && systemctl enable docker  &&  docker --version

Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

Docker version 27.3.1, build ce12230

# 验证安装

[root@localhost ~]# docker version

Client: Docker Engine - Community

二、配置仓库

1、新建目录，存放daemon.json文件

[root@localhost ~]#  mkdir -p /etc/docker

2、写入docker仓库地址到daemon.json文件

[root@localhost ~]# tee /etc/docker/daemon.json <<-'EOF'

{

  "registry-mirrors": ["https://docker.fxxk.dedyn.io"]

}

EOF

注：

        1）、网上说的修改成阿里的仓库地址已不可用，官方调整说明：

[root@localhost ~]# curl https://x3eaedgw.mirror.aliyuncs.com

This request is forbidden. Please proceed to https://help.aliyun.com/zh/acr/product-overview/product-change-acr-mirror-accelerator-function-adjustment-announcement to view the announcement.

       2 ）、这里提供的 registry-mirrors 如果有天也不可用，修改一个可用的就可以了。

3、重启docker服务

[root@localhost ~]# systemctl daemon-reload && systemctl restart docker

4、拉取镜像/运行容器 成功

[root@localhost ~]# docker pull hello-world

Using default tag: latest

latest: Pulling from library/hello-world

c1ec31eb5944: Pull complete

Digest: sha256:305243c734571da2d100c8c8b3c3167a098cab6049c9a5b066b6021a60fcb966

Status: Downloaded newer image for hello-world:latest

docker.io/library/hello-world:latest

[root@localhost ~]# docker run hello-world

Hello from Docker!

This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:

 1. The Docker client contacted the Docker daemon.

 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.

    (amd64)

 3. The Docker daemon created a new container from that image which runs the

    executable that produces the output you are currently reading.

 4. The Docker daemon streamed that output to the Docker client, which sent it

    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:

 $ docker run -it ubuntu bash
