1、錯誤內容
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)2、分析原因
看上面的內容，說的是containerd.io >= 1.2.2-3 ，意思就是 containerd.io 的版本必須大於等於 1.2.2-3
3、解決
1、要么就降低docker 的版本
2、如果不想降低docker 版本，那么就更新 containerd.io 的版本
wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm yum install -y containerd.io-1.2.6-3.3.el7.x86_64.rpm
然后重新安裝最新版本的docker 即可成功安裝
4、檢查是否安裝成功
docker -v
