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

方法一.  yum安装

     yum install *rhsm*

方法二

     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
