这篇文章介绍了CentOS 8 安装Docker 报错requires container-selinux >= 2:2.x，分享给大家做个参考，收藏Java资料网收获更多编程知识

什么是 Docker

简单来说，Docker 是一个开源的容器化平台，它可以让你：把应用程序和它所有的依赖打包到一个“容器”中运行。

在传统部署中，你可能遇到这样的问题：

“在我机器上能跑啊，怎么你那里就出错了？”

这通常是因为你们的环境（系统版本、依赖库、配置）不一致。

而 Docker 可以彻底解决这个问题。

安装 Docker

由于 Docker 官方并未给出安装教程，本文简单写一下 Docker Engine 的安装步骤：

安装 yum-utils

sudo yum install yum-utils -y

添加安装源到仓库

sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装 Docker

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

到目前为止都很成功，在安装的时候就开始各种环境报错。

报错如下：

sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
Updating Subscription Management repositories.
Unable to read consumer identity

This system is not registered with an entitlement server. You can use subscription-manager to register.

这需要我们自行下载，我看网上都是国外的，但是我机器访问不到，幸好找到了国内的镜像版本，如果你缺少啥，就去这里下载：

https://mirrors.aliyun.com

执行以下命令即可：

sudo yum install https://mirrors.aliyun.com/centos/8-stream/AppStream/aarch64/os/Packages/container-selinux-2.167.0-1.module_el8.6.0+926+8bef8ae7.noarch.rpm

执行后，仍在报错，如下所示：

我们执行强制执行命令，命令如下：

sudo dnf install -y --allowerasing docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

终于成功，效果如下：

太难了，期间看了stack overflow以及各种博客帖子还有问AI，一直找不到，基本都是centos 7的解决办法。不过最后总算完成了。

启动 Docker 服务

启动 Docker 服务，并设置自启动

sudo systemctl enable docker

验证 Docker

通过运行 hello-world 镜像验证 Docker Engine 安装是否成功

sudo docker run hello-world

看到以下效果基本就可以了。如图所示：

小结

本文介绍了 Docker 的基本概念及其在解决环境不一致问题中的作用，并详细记录了在 CentOS 8 系统上安装 Docker 时遇到的各种依赖冲突与报错问题。通过使用阿里云镜像和强制安装命令，最终成功完成了安装与验证。
