最近又出來個kubesphere的工具用來管理k8s，今天特意來安裝體驗下；
github地址：https://github.com/pixiake/ks-installer
官方使用文檔：https://kubesphere.io/docs/advanced-v2.0/zh-CN/installation/all-in-one/
當前環境：
k8s集羣已經安裝完成，用kubesphere管理現有的k8s集羣；
k8s版本爲1.14
系統爲centos7.6
kubesphere使用要求：
kubernetes version > 1.13.0
helm version > 2.10.0
a default storage class must be in kubernetes cluster
安裝完成後默認用戶名密碼：
用戶名：admin
密碼：P@88w0rd
安裝步驟大概記錄：
kubectl create ns kubesphere-system
kubectl create ns kubesphere-monitoring-system
#訪問etcd用到的secret
kubectl -n kubesphere-monitoring-system create secret generic kube-etcd-client-certs --from-file=etcd-client-ca.crt=ca.pem --from-file=etcd-client.crt=etcd-key.pem --from-file=etcd-client.key=etcd.pem
#管理k8s用到的secret
kubectl -n kubesphere-system create secret generic kubesphere-ca --from-file=ca.crt=ca.pem --from-file=ca.key=ca-key.pem
#clone好github項目，執行下面的這條命令
cd deploy
kubectl apply -f kubesphere-installer.yaml
#執行完上面的命令，可以通過下面的命令，查看安裝日誌
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l job-name=kubesphere-installer -o jsonpath='{.items[0].metadata.name}') -f
#查看安裝結果，STATUS跟下面保持一致才說明安裝成功
[root@ks-allinone deploy]# kubectl get pods -n kubesphere-system

1.在安裝的時提示metrics-server已經安裝，導致安裝中斷；
解析辦法：在kubesphere-installer.yaml的configMap增加配置：metrics_server_enable: False（默認是沒有的）
apiVersion: v1 data: ks-config.yaml: | kube_apiserver_host: 10.10.5.208:6443 etcd_tls_enable: True etcd_endpoint_ips: 10.10.5.169,10.10.5.183,10.10.5.184 disableMultiLogin: True elk_prefix: logstash metrics_server_enable: False # local_registry: 192.168.1.2:5000 kind: ConfigMap metadata: name: kubesphere-config namespace: kubesphere-system
增加Ingress配置：
apiVersion: extensions/v1beta1 kind: Ingress metadata: name: kubesphere namespace: kubesphere-system annotations: #kubernetes.io/ingress.class: traefik kubernetes.io/ingress.class: nginx spec: rules: - host: ks.staplescn.com http: paths: - path: backend: serviceName: ks-console servicePort: 80
