pod启动一分钟了 还是出去未创建的状态，发现是无法下载镜像，

[[email protected] pod]# kubectl get pod

[[email protected] pod]# kubectl describe pod nginx

我们去节点上手动拉取镜像 试一试：也是不行的

[[email protected] ~]# docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latestTrying to pull repository registry.access.redhat.com/rhel7/pod-infrastructure ... 
open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory

我百度了一下

我们现在不需要去更改
更改下载镜像的地址为私有仓库的地址

[[email protected] ~]# vim /etc/kubernetes/kubelet 
#这里指定地址  是从红帽官方去pull的 
# pod infrastructure container
KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=registry.access.redhat.com/rhel
7/pod-infrastructure:latest"

把这个地址 改成私有仓库地址 ，就可以从私有仓库pull了

docker search ylmcr7/pod-infrastructure:latest
docker tag ylmcr7/pod-infrastructure:latest 10.0.0.61:5000/pod-infrastructure:latest


[[email protected] ~]# vim /etc/kubernetes/kubelet 
KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=10.0.0.61:5000/pod-infrastructure:latest"

systemctl restart kubelet.service

[[email protected] pod]# kubectl get pod
NAME      READY     STATUS    RESTARTS   AGE
