Error: Package: 3:docker-ce-18.09.6-3.el7.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2.9
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
如何解决报错？
安装更高版本的container-selinux即可： 更多版本参考http://mirror.centos.org/centos/7/extras/x86_64/Packages/
[root@okqvd ~]# yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.95-2.el7_6.noarch.rpm
再尝试安装docker-ce，即可：
[root@okqvd ~]# yum install docker-ce
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
