解决k8s集群中安装ks3.4.1开启日志失败问题

问题

安装kubesphere v3.4.1时，开启了日志功能，部署时有三个pod报错了

Failed to pull image “busybox:latest”: rpc error: code = Unknown desc = failed to pull and unpack image “docker.io/library/busybox:latest”: failed to copy: httpReadSeeker: failed open: unexpected status code https://registry-1.docker.io/v2/library/busybox/manifests/sha256:50aa4698fa6262977cff89181b2664b99d8a56dbca847bf62f2ef04854597cf8: 429 Too Many Requests - Server message: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

解决办法

因为是离线环境所有访问不到这个docker.io，需要改为私有仓库地址。

使用Kubesphere或者命令进行编辑，修改 sts 使用的 busyboy 镜像为本地镜像

kubectl edit sts opensearch-cluster-data -n kubesphere-logging-system 
kubectl edit sts opensearch-cluster-master -n kubesphere-logging-system

本文修改后 image 内容（自己根据实际情况修改域名前缀）

registry.opsxlab.cn/library/busybox:latest

使用 kubectl get pod -A 查看

解决private key does not match public key
使用 kubekey 推送镜像时，registry节点报private key does not match public key，因为使用 kk init registry 初始化会拷贝/etc/ssl/registry/ssl/的证书，需要吧 /etc/ssl/registry/ssl/ 下面的文件删除和解压的kubekey目录一起删除。重新执行kk init registry
