k8s部署的中遇到的一些问题的解决

最主要的问题是：details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or directory)
第一步：执行一下两个命令
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
这两个命令会生成/etc/rhsm/ca/redhat-uep.pem文件

第二步：拉取镜像
[root@localhost]# docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest

第三步：删除原来创建的rc

[root@localhost /]# kubectl delete -f mysql-rc.yaml

重新创建

[root@localhost /]# kubectl create -f mysql-rc.yaml

再次查看状态

[root@localhost /]# kubectl get pod
