RuoyiCloudPlus结合SkyWalking-9.4.0 docker部署流程

一、SkyWalking-9.4.0 docker部署流程

• docker-compse.yml

  sky-oap:
    image: apache/skywalking-oap-server:9.3.0
    container_name: ruoyi-sky-oap
    ports:
      - "11800:11800"
      - "12800:12800"
    environment:
      JAVA_OPTS: -Xms1G -Xmx2G
      #记录数据的有效期，单位天
      SW_CORE_RECORD_DATA_TTL: 7
      #分析指标数据的有效期，单位天
      SW_CORE_METRICS_DATA_TTL: 7
      SW_STORAGE: elasticsearch
      SW_STORAGE_ES_CLUSTER_NODES: 192.168.1.8:9200
      TZ: Asia/Shanghai
    #network_mode: "host"

  sky-ui:
    image: apache/skywalking-ui:9.3.0
    container_name: ruoyi-sky-ui
    ports:
      - "18080:18080"
    environment:
      SW_SERVER_PORT: 18080
      SW_OAP_ADDRESS: http://192.168.1.8:12800
      #SW_ZIPKIN_ADDRESS: http://oap:9412
      TZ: Asia/Shanghai
    depends_on:
      - sky-oap
    links:
      - sky-oap
    #network_mode: "host"

• 因为要将数据存储在es，以下给出es docker-compose文件

version: '3.8'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.17.6
    container_name: elasticsearch
    restart: always
    ports:
      - 9200:9200
      - 9300:9300
    environment:
      - discovery.type=single-node
      - TZ=Asia/Shanghai
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms1024m -Xmx1024m"
    volumes:
      - /home/elasticsearch/data:/usr/share/elasticsearch/data
    ulimits:
      memlock:
        soft: -1
        hard: -1

• 如果OAP报如下错

oap  | 2023-06-14 01:18:55,913 org.apache.skywalking.oap.server.core.storage.model.ModelInstaller 54 [main] INFO  [] - table: ui_template does not exist
oap  | 2023-06-14 01:18:55,960 org.apache.skywalking.oap.server.core.storage.model.ModelInstaller 54 [main] INFO  [] - table: zipkin_span does not exist
oap  | 2023-06-14 01:18:56,017 org.apache.skywalking.library.elasticsearch.client.TemplateClient 139 [armeria-eventloop-epoll-6-3] ERROR [] - [9.4.0-520d531] Failed to create / update index template sw_zipkin_span
oap  | java.util.concurrent.CompletionException: java.lang.RuntimeException: {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"composable template [sw_zipkin_span] template after composition is invalid"}],"type":"illegal_argument_exception","reason":"composable template [sw_zipkin_span] template after composition is invalid","caused_by":{"type":"illegal_argument_exception","reason":"invalid composite mappings for [sw_zipkin_span]","caused_by":{"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_doc]: analyzer [oap_analyzer] has not been configured in mappings","caused_by":{"type":"illegal_argument_exception","reason":"analyzer [oap_analyzer] has not been configured in mappings"}}}},"status":400}

在官方issue中找到解答，由于挂载的es目录为原来8.7.0版本生成及采集的数据，导致es初始化数据失败，需要删除原目录数据/home/elasticsearch/data或者重新指定文件目录即可。

二、集成RuoyiCloudPlus

1. 下载java探针

这里使用最新8.16.0版本的java-gent客户端，配置文件在config/agent.config，参考配置文档https://skywalking.apache.org/docs/skywalking-java/v8.16.0/en/setup/service-agent/java-agent/configurations/

2. 普通的java文件，启动jar包配置命令如下

-javaagent:/home/skywalking/skywalking-agent/skywalking-agent.jar -Dskywalking.agent.service_name=test::服务名 -Dskywalking.collector.backend_service=192.168.24.22:11800

3. 结合Dockerfile及容器docker-compose，制作微服务镜像

• Dockerfile

FROM anapsix/alpine-java:8_server-jre_unlimited

RUN mkdir -p /ruoyi/system/logs \
    /ruoyi/system/temp \
    /ruoyi/skywalking/agent

WORKDIR /ruoyi/system

ENV SERVER_PORT=9201

EXPOSE ${SERVER_PORT}

# 拷贝打包后的jar到容器内
ADD ./target/ruoyi-system.jar ./app.jar

ENTRYPOINT ["java", \
            "-Djava.security.egd=file:/dev/./urandom", \
            "-Dserver.port=${SERVER_PORT}", \
            "-Dskywalking.agent.service_name=ruoyi-system", \
#指定探针数据上报的网络地址
            "-Dskywalking.collector.backend_service=192.168.1.8:11800", \
#该句只是指定配置，真正的探针文件在部署服务时，在docker-compose中指定
            "-javaagent:/ruoyi/skywalking/agent/skywalking-agent.jar", \
            "-jar", "app.jar"]

• docker-compose

  ruoyi-gateway:
    image: ruoyi/ruoyi-gateway:1.6.0
    container_name: ruoyi-gateway
    environment:
      # 时区上海
      TZ: Asia/Shanghai
    ports:
      - "8080:8080"
    volumes:
      # 配置文件
      - /docker/ruoyi-gateway/logs/:/ruoyi/gateway/logs
      # 指定skywalking 探针位置
      - /docker/skywalking/agent/:/ruoyi/skywalking/agent
    privileged: true
    #network_mode: "host"

• 启动gateway微服务模块后，发起请求，便可以在sky-ui中看到数据
