项目集成SkyWalking，基于k8s搭建

本文主要是介绍项目集成SkyWalking，基于k8s搭建，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、搭建SkyWalking

官方文档（英文）：skywalking/docs at master · apache/skywalking 

中文可以使用：GitHub - SkyAPM/document-cn-translation-of-skywalking: [已过期,请使用官网AI文档] The CN translation version of Apache SkyWalking document

需要搭建服务：SkyWalkingOAP，SkyWalkingUi, Elastisearch

1.先搭建SkyWalkingOAP服务.

SkyWalkingOAP 负责数据的收集、分析和存储。通过部署oap来启动SkyWalking的基础服务。

1.1首先搭建工作负载：

kind: Deployment
apiVersion: apps/v1
metadata:
  name: skywalk-970-oap
  namespace: common
  labels:
    app: skywalk-970-oap
  annotations:
    deployment.kubernetes.io/revision: '4'
    kubesphere.io/creator: fly
spec:
  replicas: 1
  selector:
    matchLabels:
      app: skywalk-970-oap
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: skywalk-970-oap
        release: skywalking
      annotations:
        kubesphere.io/creator: fly
        kubesphere.io/restartedAt: '2024-05-22T03:21:09.886Z'
    spec:
      volumes:
        - name: host-time
          hostPath:
            path: /etc/localtime
            type: ''
      containers:
        - name: oap
          image: '159.75.136.188:40080/szqc2023002/skywalking-oap-server:9.7.0'
          ports:
            - name: grpc
              containerPort: 11800
              protocol: TCP
            - name: rest
              containerPort: 12800
              protocol: TCP
          env:
            - name: JAVA_OPTS
              value: '-Xmx1g -Xms1g'
            - name: SW_CORE_RECORD_DATA_TTL
              value: '2'
            - name: SW_CORE_METRICS_DATA_TTL
              value: '2'
            - name: SW_STORAGE
              value: elasticsearch
            - name: SW_STORAGE_ES_CLUSTER_NODES
              value: 'elasticsearch762.common:9200'
          resources:
            limits:
              memory: 2Gi
            requests:
              memory: 1Gi
          volumeMounts:
            - name: host-time
              readOnly: true
              mountPath: /etc/localtime
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: IfNotPresent
      restartPolicy: Always
      terminationGracePeriodSeconds: 30
      dnsPolicy: ClusterFirst
      securityContext: {}
      schedulerName: default-scheduler
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxUnavailable: 25%
      maxSurge: 25%
  revisionHistoryLimit: 10
  progressDeadlineSeconds: 600
我们存储日志的方式是使用es.

1.2然后搭建SkyWalking服务

kind: Service
apiVersion: v1
metadata:
  name: skywalk-970-oap
  namespace: common
  labels:
    app: skywalk-970-oap
  annotations:
    kubesphere.io/creator: fly
spec:
  ports:
    - name: tcp-11800
      protocol: TCP
      port: 11800
      targetPort: 11800
      nodePort: 30876
    - name: tcp-12800
      protocol: TCP
      port: 12800
      targetPort: 12800
      nodePort: 31012
  selector:
    app: skywalk-970-oap
    release: skywalking
  clusterIP: 10.233.43.222
  clusterIPs:
    - 10.233.43.222
  type: NodePort
  sessionAffinity: None
  externalTrafficPolicy: Cluster
  ipFamilies:
    - IPv4
  ipFamilyPolicy: SingleStack
  internalTrafficPolicy: Cluster
至此，SkyWalkingOAP服务完成。

2.搭建SkyWalkingUi服务

SkyWalkibgUi是SkyWalking的可视化界面服务。用于展示分布式系统的监控数据。我们可以通过WebUi来访问和使用SkyWalking。

2.1首先搭建SkyWalkingUi的工作负载

kind: Deployment
apiVersion: apps/v1
metadata:
  name: skywalk-970-ui
  namespace: common
  labels:
    app: skywalk-970-ui
  annotations:
    deployment.kubernetes.io/revision: '4'
    kubesphere.io/creator: fly
spec:
  replicas: 1
  selector:
    matchLabels:
      app: skywalk-970-ui
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: skywalk-970-ui
        release: skywalking
      annotations:
        kubesphere.io/creator: fly
        kubesphere.io/restartedAt: '2024-05-22T03:10:50.693Z'
    spec:
      containers:
        - name: sk-ui
          image: 'apache/skywalking-ui:9.7.0'
          ports:
            - containerPort: 8080
              protocol: TCP
          env:
            - name: SW_OAP_ADDRESS
              value: 'http://skywalk-970-oap.common:12800'
          resources: {}
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: IfNotPresent
      restartPolicy: Always
      terminationGracePeriodSeconds: 30
      dnsPolicy: ClusterFirst
      securityContext: {}
      schedulerName: default-scheduler
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxUnavailable: 25%
      maxSurge: 25%
  revisionHistoryLimit: 10
  progressDeadlineSeconds: 600
2.2搭建SkyWalkingUi服务

kind: Service
apiVersion: v1
metadata:
  name: skywalk-970-ui
  namespace: common
  labels:
    app: skywalk-970-ui
  annotations:
    kubesphere.io/creator: fly
spec:
  ports:
    - name: http-8080
      protocol: TCP
      port: 8080
      targetPort: 8080
      nodePort: 31195
  selector:
    app: skywalk-970-ui
    release: skywalking
  clusterIP: 10.233.2.227
  clusterIPs:
    - 10.233.2.227
  type: NodePort
  sessionAffinity: None
  externalTrafficPolicy: Cluster
  ipFamilies:
    - IPv4
  ipFamilyPolicy: SingleStack
  internalTrafficPolicy: Cluster
至此SkyWalkingUi服务搭建完成。

3.搭建Es服务，用于存储SkyWalking日志。

3.1搭建Es服务的工作负载

kind: Deployment
apiVersion: apps/v1
metadata:
  name: elasticsearch762
  namespace: common
  labels:
    app: elasticsearch762
  annotations:
    deployment.kubernetes.io/revision: '4'
    kubesphere.io/creator: fly
    kubesphere.io/description: 未提供nodeport服务，供Skywalking做数据源
spec:
  replicas: 1
  selector:
    matchLabels:
      app: elasticsearch762
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: elasticsearch762
      annotations:
        kubesphere.io/creator: fly
        kubesphere.io/restartedAt: '2024-05-22T03:41:36.061Z'
        logging.kubesphere.io/logsidecar-config: '{}'
    spec:
      volumes:
        - name: host-time
          hostPath:
            path: /etc/localtime
            type: ''
        - name: volume-m5uec2
          configMap:
            name: elasticsearch760
            items:
              - key: elasticsearch.yml
                path: elasticsearch.yml
            defaultMode: 420
        - name: volume-vcbpgy
          configMap:
            name: elasticsearch760
            items:
              - key: jvm.options
                path: jvm.options
            defaultMode: 420
      containers:
        - name: container-3sukk2
          image: 'elasticsearch:7.6.2'
          ports:
            - name: tcp-9200
              containerPort: 9200
              protocol: TCP
            - name: tcp-9300
              containerPort: 9300
              protocol: TCP
          env:
            - name: discovery.type
              value: single-node
            - name: ES_JAVA_OPTS
              value: '-Xms1024m -Xmx1024m'
          resources: {}
          volumeMounts:
            - name: host-time
              readOnly: true
              mountPath: /etc/localtime
            - name: volume-m5uec2
              readOnly: true
              mountPath: /usr/share/elasticsearch/config/elasticsearch.yml
              subPath: elasticsearch.yml
            - name: volume-vcbpgy
              readOnly: true
              mountPath: /usr/share/elasticsearch/config/jvm.options
              subPath: jvm.options
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: IfNotPresent
      restartPolicy: Always
      terminationGracePeriodSeconds: 30
      dnsPolicy: ClusterFirst
      nodeSelector:
        kubernetes.io/hostname: worker1
      serviceAccountName: default
      serviceAccount: default
      securityContext: {}
      schedulerName: default-scheduler
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxUnavailable: 25%
      maxSurge: 25%
  revisionHistoryLimit: 10
  progressDeadlineSeconds: 600
3.2搭建Es的服务

kind: Service
apiVersion: v1
metadata:
  name: elasticsearch762
  namespace: common
  labels:
    app: elasticsearch762
  annotations:
    kubesphere.io/creator: fly
spec:
  ports:
    - name: tcp-9200
      protocol: TCP
      port: 9200
      targetPort: 9200
    - name: tcp-9300
      protocol: TCP
      port: 9300
      targetPort: 9300
  selector:
    app: elasticsearch762
  clusterIP: 10.233.7.71
  clusterIPs:
    - 10.233.7.71
  type: ClusterIP
  sessionAffinity: None
  ipFamilies:
    - IPv4
  ipFamilyPolicy: SingleStack
  internalTrafficPolicy: Cluster
至此Es搭建服务完成。需要注意的点是：SkyWalkingAOP配置的Es的变量值，要对应Es的Dns服务名称。           

- name: SW_STORAGE_ES_CLUSTER_NODES
value: 'elasticsearch762.common:9200'

二、项目集成Skywalking

在需要集成SkyWalking服务的deploy.yml添加initContainer，达到无侵入方式集成。

      dnsPolicy: ClusterFirst
      securityContext: {}
      imagePullSecrets:
        - name: zhqc-dockerhub
      schedulerName: default-scheduler
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxUnavailable: 50%
      maxSurge: 50%
  revisionHistoryLimit: 10
  progressDeadlineSeconds: 600
 

添加了挂载点：

    spec:
      volumes:
        - name: skywalking-agent
          emptyDir: {}

添加了initContainer

  initContainers:
        - name: agent-container
          image: 'apache/skywalking-java-agent:9.0.0-alpine'
          command:
            - /bin/sh
          args:
            - '-c'
            - >-
              cp -R /skywalking/agent /agent/;cp
              /skywalking/agent/optional-plugins/apm-trace-ignore-plugin-9.0.0.jar
              /agent/agent/plugins/apm-trace-ignore-plugin-9.0.0.jar;rm
              /agent/agent/plugins/apm-redisson-3.x-plugin-9.0.0.jar;echo
              trace.ignore_path=\${SW_AGENT_TRACE_IGNORE_PATH:Lettuce/**} >
              /agent/agent/config/apm-trace-ignore-plugin.config; cp
              /skywalking/agent/optional-plugins/apm-spring-cloud-gateway-3.x-plugin-9.0.0.jar
              /agent/agent/plugins/apm-spring-cloud-gateway-3.x-plugin-9.0.0.jar;
              cp
              /skywalking/agent/optional-plugins/apm-spring-webflux-5.x-plugin-9.0.0.jar
              /agent/agent/plugins/apm-spring-webflux-5.x-plugin-9.0.0.jar;
          resources: {}
          volumeMounts:
            - name: skywalking-agent
              mountPath: /agent
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: IfNotPresent

增加了SkyWalking的相关配置：

          env:
            - name: JAVA_TOOL_OPTIONS
              value: '-javaagent:/skywalking/agent/skywalking-agent.jar'
            - name: SW_AGENT_NAME
              value: zhqc-frame-gateway
            - name: SW_AGENT_COLLECTOR_BACKEND_SERVICES
              value: '192.168.10.222:30876'
            - name: SW_AGENT_TRACE_IGNORE_PATH
              value: 'GET:/actuator/**,Lettuce/**'

SkyWalking忽略的接口

  - name: SW_AGENT_TRACE_IGNORE_PATH
 value: 'GET:/actuator/**,Lettuce/**'

SkyWalking的收集服务，即SkyWalkingAOP暴漏的服务

   - name: SW_AGENT_COLLECTOR_BACKEND_SERVICES
   value: '192.168.10.222:30876'

部署服务之后，就可以在SKyWalking看到该服务。

三、项目将日志集成到SkyWalking中。

1.引入pom包

<!-- https://mvnrepository.com/artifact/org.apache.skywalking/apm-toolkit-trace -->
<dependency><groupId>org.apache.skywalking</groupId><artifactId>apm-toolkit-trace</artifactId><version>9.0.0</version>
</dependency><!-- https://mvnrepository.com/artifact/org.apache.skywalking/apm-toolkit-logback-1.x -->
<dependency><groupId>org.apache.skywalking</groupId><artifactId>apm-toolkit-logback-1.x</artifactId><version>9.0.0</version>
</dependency></dependencies>

2.修改logback-spring.xml的配置

<?xml version="1.0" encoding="UTF-8" ?>
<!-- 级别从高到低 OFF 、 FATAL 、 ERROR 、 WARN 、 INFO 、 DEBUG 、 TRACE 、 ALL -->
<!-- 日志输出规则 根据当前ROOT 级别，日志输出时，级别高于root默认的级别时 会输出 -->
<!-- 以下 每个配置的 filter 是过滤掉输出文件里面，会出现高级别文件，依然出现低级别的日志信息，通过filter 过滤只记录本级别的日志 -->
