如何修复docker-ce的Cannot download repodata/repomd.xml: All mirrors were tried。

问题

按照当前（截至2021年12月13日）Docker文档设置Docker yum/dnf存储库，得到错误Cannot download repodata/repomd.xml: All mirrors were tried与yum install docker-ce。

在Fedora上安装Docker引擎
在RHEL上安装Docker引擎

环境

与8.4和8.5一起复制。但是，其他Fedora/RHEL/CentOS也会有相同的问题。

$ cat /etc/os-release
NAME="Red Hat Enterprise Linux"
VERSION="8.5 (Ootpa)"

原因

Docker文档中指定的命令会生成不正确的存储库配置。
根据Changes to dockerproject.org APT and YUM repositories，Docker的存储库现在被移动到download.docker.com。文档链接到Docker文档，例如在Fedora上安装Docker引擎。

我需要做什么？

如果您当前使用的是www.example.com或www.example.com上的APT或YUM存储库dockerproject.orgdockerproject.com，请更新以使用download.docker.com上的存储库。
您可以在文档中找到CentOS、Debian、Fedora和Ubuntu的说明。
请按照以下说明操作：

$ sudo dnf config-manager \
    --add-repo \
    https://download.docker.com/linux/fedora/docker-ce.repo

该命令创建的/etc/yum.repos.d/docker-ce.repo具有错误的URL。

[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://download.docker.com/linux/fedora/$releasever/$basearch/stable # <--- Wrong URL
enabled=1
gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg

如Unable to install docker on rhel 8 linux中所述，它应该是：

[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://download.docker.com/linux/centos/$releasever/$basearch/stable # <--- Correct URL
enabled=1
gpgcheck=1
gpgkey=https://download.docker.com/linux/centos/gpg

不确定谁应该修复此问题。请告知负责人。

溶液

对于RHEL/Fedora，请使用下面的命令，而不要使用Docker文档中指定的命令。

sudo dnf config-manager \
--add-repo=https://download.docker.com/linux/centos/docker-ce.repo

如果已经创建了不正确的配置。

sed -i -e 's/baseurl=https:\/\/download\.docker\.com\/linux\/\(fedora\|rhel\)\/$releasever/baseurl\=https:\/\/download.docker.com\/linux\/centos\/$releasever/g' /etc/yum.repos.d/docker-ce.repo

简化@mon解决方案
编辑此文件/etc/yum.repos.d/docker-ce.repo

If you're using fedora: 
   then compare the example below with your file (make sure 
   you have the word fedora in the baseurl and the gpgkey)

If you're using a different distro (like centos):
   then everywhere that you see the word fedora replace it 
   with the word centos.

例如：

[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://download.docker.com/linux/fedora/$releasever/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg

[docker-ce-stable-debuginfo]
name=Docker CE Stable - Debuginfo $basearch
baseurl=https://download.docker.com/linux/fedora/$releasever/debug-$basearch/stable

gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg

[docker-ce-stable-source]
name=Docker CE Stable - Sources
baseurl=https://download.docker.com/linux/fedora/$releasever/source/stable

gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg

[docker-ce-test]
name=Docker CE Test - $basearch
baseurl=https://download.docker.com/linux/fedora/$releasever/$basearch/test
enabled=0
gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg

[docker-ce-test-debuginfo]

baseurl=https://download.docker.com/linux/fedora/$releasever/debug-$basearch/test

gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg

[docker-ce-test-source]
name=Docker CE Test - Sources
baseurl=https://download.docker.com/linux/fedora/$releasever/source/test
enabled=0
gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg

[docker-ce-nightly]
name=Docker CE Nightly - $basearch
baseurl=https://download.docker.com/linux/fedora/$releasever/$basearch/nightly

[docker-ce-nightly-debuginfo]

我正在运行Centos Stream 9，它是一种不同的动物。就像其他人所说的，我编辑了/etc/yum.repos.d/docker-ce.repo，但不是.../linux/rhel/$releas..而是.../linux/centos/$rel...可能需要将$rel..更改为/8/

RHEL 86x_64x不支持Docker
我看到了一个解决方案，可以在/etc/yum.repos.d/docker-ce****.repo中编辑.repo文件，并将[docker-ce-stable]基本URL编辑为
https://download.docker.com/linux/centos/$releasever/$basearch/stable
Centos将与RHEL一起使用。
