kubernetes启动pod，pod状态一直不正常，查看pod状态显示

  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)

按照网上所说的解决方案：yum install *rhsm* -y

 Failed to create pod infra container: ImagePullBackOff; Skipping pod "redis-master-jj6jw_default(fec25a87-cdbe-11e7-ba32-525400cae48b)": Back-off pulling image "registry.access.redhat.com/rhel7/pod-infrastructure:latest  

解决方法：试试通过手动下载

docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest

docker pull 是还是报错

     open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory

查看下redhat-ca.crt确实不存在，registry.access.redhat.com/rhel7/pod-infrastructure:latest默认是https下载。

最终解决方案：

     1.docker search pod-infrastructure

找到可用的进行pull到本地。

2.docker pull docker.io/tianyebj/pod-infrastructure

3.docker tag pod-infrastructure 10.0.2.11:5000/pod-infrastructure  

其中10.0.2.11是本机的IP，pull下来之后push到本机的私有仓库。

4.docker push 10.0.2.11:5000/pod-infrastructure

5.vi /etc/kubernetes/kubelet 

修改 KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=10.0.2.11:5000/pod-infrastructure:latest"

6.重启

  systemctl restart kube-apiserver
systemctl restart kube-controller-manager
systemctl restart kube-scheduler
systemctl restart kubelet

systemctl restart kube-proxy

7. kubectl get pods 查看之前的pods已经正常状态Running
