Prometheus监控Tomcat需要用到的war包和jar包

**需要的软件包如下所示：**

在k8s的master节点制作一个tomcat镜像

**（1）制作tomcat镜像，按如下步骤**

mkdir /root/tomcat\_image

把上面的war包和jar包传到这个目录下

cat Dockerfile

FROM tomcat
    ADD metrics.war /usr/local/tomcat/webapps/
    ADD simpleclient-0.8.0.jar  /usr/local/tomcat/lib/
    ADD simpleclient_common-0.8.0.jar /usr/local/tomcat/lib/
    ADD simpleclient_hotspot-0.8.0.jar /usr/local/tomcat/lib/
    ADD simpleclient_servlet-0.8.0.jar /usr/local/tomcat/lib/
    ADD tomcat_exporter_client-0.0.12.jar /usr/local/tomcat/lib/

docker build -t='xianchao/tomcat_prometheus:v1' .

docker login

username：xianchao

password：1989317\*\*

docker push xianchao/tomcat\_prometheus:v1

\#上传镜像到hub仓库

docker pull xianchao/tomcat\_prometheus:v1

\#在k8s的node节点拉取镜像

**（2）基于上面的镜像创建一个tomcat实例**

cat deploy.yaml

apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: tomcat-deployment
      namespace: default
    spec:
      selector: 
        matchLabels: 
         app: tomcat
      replicas: 2 # tells deployment to run 2 pods matching the template
      template: # create pods using pod definition in this template
        metadata:
          labels:
            app: tomcat
          annotations:
            prometheus.io/scrape: 'true'
        spec:
          containers:
          - name: tomcat
            image: xianchao/tomcat_prometheus:v1
            ports:
            - containerPort: 8080
            securityContext: 
              privileged: true

通过kubectl apply更新yaml文件

kubectl apply -f deploy.yaml

**（3）创建一个service，可操作也可不操作**

cat tomcat-service.yaml

kind: Service  #service 类型
    apiVersion: v1
    metadata:
    #  annotations:
    #    prometheus.io/scrape: 'true'
      name: tomcat-service
    spec:
      selector:
        app: tomcat
      ports:
      - nodePort: 31360
        port: 80
        protocol: TCP
        targetPort: 8080
      type: NodePort

通过kubectl apply更新yaml文件

kubectl apply -f tomcat-service.yaml
