官方使用文档：https://kubesphere.io/docs/advanced-v2.0/zh-CN/installation/all-in-one/

先放上安装效果图，UI界面还是很清爽的：

 

 

当前环境：

  • k8s集群已经安装完成，用kubesphere管理现有的k8s集群；

  • k8s版本为1.14

  • 系统为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

安装完成后默认用户名密码：

  • 用户名：admin

  • 密码：P@88w0rd

 

安装步骤大概记录：

kubectl create ns kubesphere-system
kubectl create ns kubesphere-monitoring-system
#访问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项目，执行下面的这条命令 cd deploy kubectl apply -f kubesphere-installer.yaml #执行完上面的命令，可以通过下面的命令，查看安装过程日志 kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l job-name=kubesphere-installer -o jsonpath='{.items[0].metadata.name}') -f #查看安装结果，STATUS跟下面保持一致才说明安装成功 [root@ks-allinone deploy]# kubectl get pods -n kubesphere-system NAME READY STATUS RESTARTS AGE ks-account-6db466d8dc-srrwj 1/1 Running 0 149m ks-apigateway-7d77cb9495-jzmg6 1/1 Running 0 170m ks-apiserver-f8469fd47-b58rm 1/1 Running 0 166m ks-console-54c849bdc9-dfkbf 1/1 Running 0 168m ks-console-54c849bdc9-z2d5q 1/1 Running 0 168m ks-controller-manager-569456b4cd-gngm5 1/1 Running 0 170m ks-docs-6bbdcc9bfb-6jldz 1/1 Running 0 3h7m kubesphere-installer-7ph6l 0/1 Completed 1 3h11m openldap-5c986c5bff-rzqwv 1/1 Running 0 3h25m redis-76dc4db5dd-lv6kg 1/1 Running 0 149m
 

安装过程出现的错误：

1.在安装的时提示metrics-server已经安装，导致安装中断；

解析办法：在kubesphere-installer.yaml的configMap增加配置：metrics_server_enable: False（默认是没有的）

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
