CentOS installation Docker error message:
问题: package docker-ce-3:19.03.2-3.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
- package containerd.io-1.2.2-3.3.el7.x86_64 is excluded
- package containerd.io-1.2.2-3.el7.x86_64 is excluded
- package containerd.io-1.2.4-3.1.el7.x86_64 is excluded
- package containerd.io-1.2.5-3.1.el7.x86_64 is excluded
- package containerd.io-1.2.6-3.3.el7.x86_64 is excluded
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Examination revealed containerd.io this package is installed, but is version 1.2.0; it is the cause of this failure is containerd.io installation package version is too low
Solution:
1. Check Docker version, low installation version, without installing a new version Docker (this is not to introduce cumbersome installation process of a lower version)
[Root @ localhost ~] # yum list docker-ce --showduplicates | sort -r // Check the appropriate package version
[Root @ localhost ~] # yum -y install docker-ce-18.06.0.ce-3.el7 // install a lower version of the package
