k8s 安装报错details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or

 

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

解决方案：

查看/etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt （该链接就是上图中的说明） 是一个软链接，但是链接过去后并没有真实的/etc/rhsm，所以需要使用yum安装：

 

yum install *rhsm*

 

安装完成后，执行一下docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest

如果依然报错，可参考下面的方案：

 

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

 

这两个命令会生成/etc/rhsm/ca/redhat-uep.pem文件.

顺得的话会得到下面的结果。

 

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

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

replicationcontroller "mysql" created

再次查看状态

[root@localhost /]# kubectl get pod
