k8s 安裝報錯details: (open /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt: no such file or

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：

查看/etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt （該連接就是上圖中的說明） 是一個軟連接，可是連接過去後並無真實的/etc/rhsm，因此須要使用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

若是依然報錯，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文件.

順得的話會獲得下面的結果。

 

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

刪除原來建立的rc

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

從新建立

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

replicationcontroller "mysql" created

再次查看狀態

[root@localhost /]# kubectl get pod
