    Error:
     Problem: package docker-ce-3:19.03.11-3.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

## 解决方案 ##

# containerd 版本过旧升级升级即可
    dnf install -y https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
