其中最主要的問題是：details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory)

解決方案：

檢視/etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt （該連結就是上圖中的說明） 是一個軟連結，但是連結過去後並沒有真實的/etc/rhsm，所以需要使用yum安裝：

yum install *rhsm*

安裝完成後，執行一下docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest

如果依然報錯，可參考下面的方案：

wget http://mirror.centos.org/centos/7/os/x86_64/Packages/python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm

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

這兩個命令會生成/etc/rhsm/ca/redhat-uep.pem檔案.

順得的話會得到下面的結果。
