1、卸载旧版本

旧版本的 Docker 被称为docker或docker-engine。如果安装了这些,卸载它们以及相关的依赖项。

 yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine

yum如果报告没有安装这些软件包,那也没关系。

/var/lib/docker/ 的内容,包括图像、容器、卷和网络,将被保留。 Docker 引擎包现在称为 docker-ce。

[root@localhost yum.repos.d]# yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine

2、安装方法

您可以根据需要以不同的方式安装 Docker Engine:

  • 大多数用户 设置 Docker 的存储库并从中安装,以简化安装和升级任务。这是推荐的方法。

  • 一些用户下载 RPM 包并 手动安装并完全手动管理升级。这在诸如在无法访问 Internet 的气隙系统上安装 Docker 等情况下非常有用。

  • 在测试和开发环境中,一些用户选择使用自动化 的便捷脚本来安装 Docker。

3、使用存储库安装

在新主机上首次安装 Docker Engine 之前,您需要设置 Docker 存储库。之后,您可以从存储库安装和更新 Docker。

3.1、设置存储库

安装yum-utils包(提供yum-config-manager 实用程序)并设置存储库。

 yum install -y yum-utilsyum-config-manager \--add-repo \https://download.docker.com/linux/centos/docker-ce.repo
[root@localhost yum.repos.d]# yum install -y yum-utils

3.2、安装 Docker 引擎

3.2.1、安装最新版本的 Docker Engine、containerd 和 Docker Compose

安装最新版本的 Docker Engine、containerd 和 Docker Compose 或转到下一步安装特定版本:

yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

如果提示接受 GPG 密钥,请验证指纹是否匹配 060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35,如果匹配,则接受。

此命令安装 Docker,但不会启动 Docker。它还会创建一个 docker组,但是默认情况下不会向该组添加任何用户。

Available Packages

返回的列表取决于启用了哪些存储库,并且特定于您的 CentOS 版本。

3.2.3、安装特定版本

通过其完全限定的包名称安装特定版本,即包名称 ( docker-ce) 加上版本字符串(第 2 列),从第一个冒号 (:) 开始,直到第一个连字符,由连字符 ( - ) 分隔。例如,docker-ce-20.10.15。

yum install docker-ce-20.10.15 docker-ce-cli-20.10.15 containerd.io docker-compose-plugin

此命令安装 Docker,但不会启动 Docker。它还会创建一个 docker组,但是默认情况下不会向该组添加任何用户。
