如何在CentOS上安装码头？

Question

遇到一些麻烦，安装码头：

[root@rolly ~]# 
[root@rolly ~]# sudo yum install -y yum-utils
Docker CE Stable - x86_64                                                                            42 kB/s | 3.5 kB     00:00    
Package yum-utils-4.0.12-3.el8.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!

[root@rolly ~]# sudo yum install docker-ce docker-ce-cli containerd.io

Package containerd.io-1.2.0-3.el7.x86_64 is already installed.
Error: 
 Problem: package docker-ce-3:19.03.12-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed
  - cannot install the best candidate for the job

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
[root@rolly ~]# 
[root@rolly ~]# lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description:    CentOS Linux release 8.2.2004 (Core)

Codename:   Core
[root@rolly ~]# 

我应该和nobest一起去吗？

Answer 1

如果最新版本不可安装，则可以运行：

dnf install docker-ce --nobest

安装另一个版本而不是最后一个版本。有点伤感，但很管用。
