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 （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

Kubernetes中强制删除Pod

# 删除POD
kubectl delete pod PODNAME --force --grace-period=0

# 删除NAMESPACE
kubectl delete namespace NAMESPACENAME --force --grace-period=0
