解决方法：试试通过手动下载
docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest
最终解决方案
1.docker search pod-infrastructure 查找镜像
2、选择第一个镜像pull下来，docker pull docker.io/tianyebj/pod-infrastructure
3、docker tag docker.io/tianyebj/pod-infrastructure:latest 10.0.0.11:5000/pod-infrastructure:latest 更改镜像标签。
4、docker push 10.0.0.11:5000/pod-infrastructure:latest 上传到私有镜像
