[root@localhost ~]# yum install -y docker-ce
Updating Subscription Management repositories.

Docker CE Stable - x86_64 11 kB/s | 20 kB 00:01
错误：
问题: package docker-ce-3:19.03.4-3.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-1.2.10-3.2.el7.x86_64 is excluded
- 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)
解决办法：
下载docker rpm地址
https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
[root@localhost ~]# rpm -ivh containerd.io-1.2.4-3.1.el7.x86_64.rpm
警告：containerd.io-1.2.4-3.1.el7.x86_64.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID 621e9f35: NOKEY
错误：依赖检测失败：
runc 与 containerd.io-1.2.4-3.1.el7.x86_64 冲突
runc 被 containerd.io-1.2.4-3.1.el7.x86_64 取代
[root@localhost ~]# yum erase runc （erase等价与remove，删除runc）
。。。。。
[root@localhost ~]# rpm -ivh containerd.io-1.2.4-3.1.el7.x86_64.rpm
[root@localhost ~]# systemctl start docker.service
[root@localhost ~]# systemctl enable docker.service
