标题: Rocky Linux9下安装Docker和卸载Docker
前提条件

安装好Rocky Linux9，可参考 Vmware下安装Rocky Linux9.4

安装Docker

精简版下令

  1. yum install -y yum-utils
  3. yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
  5. yum install -y docker-ce
  7. systemctl enable docker --now
  9. mkdir -p /etc/docker
  11. tee /etc/docker/daemon.json <<-'EOF'
  12. {
  13.   "registry-mirrors": [
  14.     "https://registry.docker-cn.com",
  15.     "http://hub-mirror.c.163.com",
  16.     "https://docker.mirrors.ustc.edu.cn"
  17.   ]
  18. }
  19. EOF
  22. systemctl daemon-reload
  24. systemctl restart docker
  26. docker version
  28. docker info
  30. docker run hello-world
复制代码

具体操作过程

安装须要的包
  1. [root@localhost ~]# yum install -y yum-utils
  2. Last metadata expiration check: 0:25:51 ago on Mon Sep  9 15:49:04 2024.
  3. Package yum-utils-4.3.0-13.el9.noarch is already installed.
  4. Dependencies resolved.
  5. Nothing to do.
  6. Complete!
复制代码

添加docker-ce repo
  1. [root@localhost ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
  2. Adding repo from: https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
复制代码

安装docker-ce
  1. [root@localhost ~]# yum install -y docker-ce
  2. ...
  3. 省略日志输出
  4. ...
复制代码
设置开机主动启动docker及启动docker
  1. [root@localhost ~]# systemctl enable docker --now
复制代码
配置国内镜像加速，这里配置三个镜像加速地址，根据需要可以添加更多镜像地址
  1. [root@localhost ~]# mkdir -p /etc/docker
  2. [root@localhost ~]# tee /etc/docker/daemon.json <<-'EOF'
  3. {
  4.   "registry-mirrors": [
  5.    "https://registry.docker-cn.com",
  6.    "http://hub-mirror.c.163.com",
  7.    "https://docker.mirrors.ustc.edu.cn"
  8.   ]
  9. }
  10. EOF
  11. {
  12.   "registry-mirrors": [
  13.    "https://registry.docker-cn.com",
  14.    "http://hub-mirror.c.163.com",
  15.    "https://docker.mirrors.ustc.edu.cn"
  16.   ]
  17. }
复制代码

重新加载配置及重启docker
  1. [root@localhost ~]# systemctl daemon-reload
  2. [root@localhost ~]# systemctl restart docker
复制代码

验证docker是否可用
下载一个 “hello-world” 测试镜像并在容器中运行它，当容器运行时，它会打印确认消息并退出。
  1. [root@localhost ~]# docker run hello-world
  2. Unable to find image 'hello-world:latest' locally
  3. latest: Pulling from library/hello-world
  4. c1ec31eb5944: Pull complete
  5. Digest: sha256:53cc4d415d839c98be39331c948609b659ed725170ad2ca8eb36951288f81b75
  6. Status: Downloaded newer image for hello-world:latest
  7. ​
  8. Hello from Docker!
  9. This message shows that your installation appears to be working correctly.
  10. ​
  11. To generate this message, Docker took the following steps:
  12. 1. The Docker client contacted the Docker daemon.
  13. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
  14.    (amd64)
  15. 3. The Docker daemon created a new container from that image which runs the
  16.    executable that produces the output you are currently reading.
  17. 4. The Docker daemon streamed that output to the Docker client, which sent it
  18.    to your terminal.
  19. ​
  20. To try something more ambitious, you can run an Ubuntu container with:
  21. $ docker run -it ubuntu bash
  22. ​
  23. Share images, automate workflows, and more with a free Docker ID:
  24. https://hub.docker.com/
  25. ​
  26. For more examples and ideas, visit:
  27. https://docs.docker.com/get-started/
  28. ​
  29. [root@localhost ~]#
  30. ​
复制代码
提示：网络的原因可能需要多实验几次才气下载乐成，如果下载不了，还可以实验添加更多可用镜像。

卸载docker

卸载docker下令
  1. [root@localhost ~]# yum remove -y docker-ce
复制代码

删除docker相干文件
主机上的镜像、容器、卷或自定义配置文件不会主动删除，使用如下下令删除所有的镜像、容器和卷。
  1. [root@localhost ~]# rm -rf /var/lib/docker
  2. [root@localhost ~]# rm -rf /var/lib/containerd
复制代码

完成！enjoy it！
