mysql 鏡像下載失敗，報錯如下：

報錯一：image pull failed for registry.access.redhat.com/rhel7/pod-infrastructure:latest, this may be because there are no credentials on this request. details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory)

解決方法：

yum install *rhsm* -y
