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": "** [Docker Hub Search](https://docker.fxxk.dedyn.io "Docker Hub Search")**"
}
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 r egistry-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:
-
The Docker client contacted the Docker daemon.
-
The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
- The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
- 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
