K8S部署WGCLOUD運維監控系統

1.WGCLOUD介紹

WGCLOUD屬於極簡及高效的主機監控系統，支援主機各種指標監測，
並且支援故障告警資訊推送，開源系統足以滿足我們對測試環境機器的監控，所以用起來。

2.WGCLOUD基於K8S部署
2.1.官網下載v3.4.6版本tar.gz安裝包

wgcloud-v3.4.6.tar.gz

2.2.新建資料庫，匯入資料

(1)解壓wgcloud-v3.4.6.tar.gz安裝包
(2)在解壓目錄下會發現wgcloud-MySQL.sql、wgcloud-Oracle.sql和wgcloud-PostgreSQL.sql三份sql檔案
(3)根據自己的需要選擇對應的sql檔案匯入,筆者這裡以mysql為主
(4)修改server/config/application.yml檔案的資料庫連線資訊，更新為自己的資料庫連線資訊及對應的驅動即可

2.3.編寫server端Dockerfile

#基礎映象
FROM java:8
#作者
MAINTAINER xxx <xxx@xxx.com>
#切換映象目錄，進入usr目錄
WORKDIR /wgcloud
RUN mkdir wgcloud
ADD . /wgcloud/
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
RUN echo 'Asia/Shanghai' >/etc/timezone
CMD ["/wgcloud/wgcloud/server/start.sh"]

2.4.製作映象

docker buld -t harbor.xxx.xxx/qa-dev/wgcloud/wgcloud:v1 .

2.5.將映象推送至harbor倉庫

docker push harbor.xxx.xxx/qa-dev/wgcloud/wgcloud:v1

2.6.編寫k8s yaml檔案

kind: Deployment
metadata:
  name: wgcloud-deployment
  labels:
    app: wgcloud
    namespace: k8s-jenkins  #這裡根據自己的namespace做調整
spec:
  replicas: 1 #控制管理執行的pod個數
  selector:
    matchLabels:   #標籤
      app: wgcloud
  template:
    metadata:
      labels:
        app: wgcloud
    spec:
      containers:
        - name: wgcloud
          image: harbor.xxx.xxx/qa-dev/wgcloud/wgcloud:v1
          imagePullPolicy: Always
          ports:
            - containerPort: 9997  #容器暴露的埠號-1
            - containerPort: 9998  #容器暴露的埠號-2
            - containerPort: 9999  #容器暴露的埠號-3
      imagePullSecrets:
        - name: docker-harbor-slave

---

apiVersion: v1
kind: Service
metadata:
  name: wgcloud-service
spec:
  selector:
    app: wgcloud
  ports:
    - name: http-test1
      port: 9997
      protocol: TCP
      nodePort: xxx-1  #根據自己的nodePort做調整
    - name: http-test2
      port: 9998
      protocol: TCP
      nodePort: xxx-2
    - name: http-test3
      port: 9999
      protocol: TCP
      nodePort: xxx-3  #指定節點開放的埠
  type: NodePort
  selector:
    app: wgcloud

2.7.接入jenkins，pipeline


def label = "slave-${UUID.randomUUID().toString()}"

podTemplate(label: label, serviceAccount: "xxx，擁有某某個角色的賬號",imagePullSecrets: [ 'xxx'  拉取映象的密碼],  containers: [
  containerTemplate(name: 'kubectl', image: 'harbor.pwesports.net/qa-dev/kubectl:v1', command: 'cat', ttyEnabled: true)
], volumes: [
  hostPathVolume(mountPath: '/home/jenkins/.kube', hostPath: '/root/.kube'),
],yaml: '''
          spec:
            containers:
            - name: kaniko
              image: harbor.pwesports.net/qa-dev/kaniko:v2
              command:
              - /busybox/cat
              tty: true
              volumeMounts:
              - name: docker-config
                mountPath: /kaniko/.docker
            restartPolicy: Never
            volumes:
            - name: docker-config
              secret:
                secretName: docker-harbor-slave
                items:
                  - key: .dockerconfigjson
                    path: config.json
            hostAliases:
            - ip: "172.16.xxx.xxx"
              hostnames:  #程式碼倉庫地址
              - "gitlab.xxx.xxx"
            - ip: "172.16.xxx.xxx"  ###harbor地址
              hostnames:
              - "harbor.xxx.xxx"
          ''') {
  node(label) {

     stage('執行 Kubectl') {
        git credentialsId: 'xxxx-4c16-479c-8cd3-2b29f828e71b', url: 'http://gitlab.xxx.xxx/QA/xxx.git', branch: 'master'
        container('kubectl') {
             sh """
                kubectl apply -f ${workspace}/k8s-config/wgcloud.yaml
             """
        }
     }
  }
}
