容器报错信息为（两种）：
FailedSynError syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for registry.access.redhat.com/rhel7/pod-infrastructure:latest, this may be because there are no credentials on this request. details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory)" 13m 11s 56 {kubelet 127.0.0.1} Warning FailedSync Error syncing pod, skipping: failed to "StartContainer" for "POD" with ImagePullBackOff: "Back-off pulling image \"registry.access.redhat.com/rhel7/pod-infrastructure:latest\"" Error syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for registry.access.redhat.com/rhel7/pod-infrastructure:latest, this may be because there are no credentials on this request. details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory)"
大致意思就是：未能通过ErrImagePull为“POD”启动“StartContainer”：“对于registry.access.redhat.com/rhel7/pod-infrastructure:latest，图像拉出失败，这可能是因为此请求上没有证书
检查发现：/etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt这个目录中是一个软连接
发现实际上并没有这个文件：
其实在我的k8s编排工具使用文档中我提过这个错误，说是因为证书导致的， 然后下载一个 yum remove *rhsm* -y 就可以解决，但是我最近温习一遍后发现这个rhsm文件被调换了，下载后发现是空的，然后找方法解决。
解决方法：下载rpm包安装
wget http://mirror.centos.org/centos/7/os/x86_64/Packages/python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm rpm2cpio python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm | cpio -iv --to-stdout ./etc/rhsm/ca/redhat-uep.pem | tee /etc/rhsm/ca/redhat-uep.pem
注释：rpm2cpio命令用于将rpm软件包转换为cpio格式的文件
cpio命令主要是用来建立或者还原备份档的工具程序，cpio命令可以复制文件到归档包中，或者从归档包中复制文件。
-i 还原备份档
-v 详细显示指令的执行过程
最后解决了！
使用k8s创建容器一直处于ContainerCreating状态
