方法一. yum安装
yum install *rhsm*
方法二 （我是用这方法解决的）
执行命令：
① wget http://mirror.centos.org/centos/7/os/x86_64/Packages/python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm
② 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
前两个命令会生成/etc/rhsm/ca/redhat-uep.pem文件.
③ docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest
此时kubectl get pods 会显示running状态
[root@docker-master1 ~]# kubectl get pods NAME READY STATUS RESTARTS AGE mynginx 1/1 Running 0 13m
