安装 Docker（使用国内源）

news 2025/7/2 1:36:07

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

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
