k8s部署Skywalking及java接入agent

Skywalking由国内开源
大体架构是这样子

我用的是dockerhub的镜像

docker pull apache/skywalking-ui:8.5.0
docker pull apache/skywalking-oap-server:8.5.0-es7
docker pull elasticsearch:7.9.0

spec:
  template:
    metadata:
    spec:
      containers:
      - env:
        - name: discovery.type
          value: single-node
        image: elasticsearch:7.9.0
        imagePullPolicy: IfNotPresent
        name: es
        ports:
        - containerPort: 9200
          name: db
          protocol: TCP
        - containerPort: 9300
          name: transport
          protocol: TCP
        stdin: true
        terminationMessagePath: /dev/termination-log
        terminationMessagePolicy: File
        tty: true
      dnsPolicy: ClusterFirst
