containerd.io-1.2.6-3.3.el7.x86_64.rar

yum -y install docker-ce，安装高版本docke-ce，报错Problem: package docker-ce-3:19.03.8-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed，意思就是 containerd.io 的版本必须大于等于 1.2.2-3，从https://download.docker.com下载很慢，这是相应的高版本containerd.io。或者直接安装低版本docker-ce,yum -y install docker-ce-18.06.0.ce-3.el7
