部署

不废话，直接上docker-compose

version: '3.8'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.17.6
    container_name: elasticsearch
    restart: on-failure:5
    ports:
      - 9200:9200
      - 9300:9300
    environment:
      - discovery.type=single-node
      - TZ=Asia/Shanghai
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms1024m -Xmx1024m"
    volumes:
      - ./elasticsearch/data:/usr/share/elasticsearch/data
    ulimits:
      memlock:
        soft: -1
        hard: -1
  oap:
    image: docker.io/apache/skywalking-oap-server:9.4.0
    container_name: oap
    depends_on:
      - elasticsearch
    restart: on-failure:5
    ports:
      - 11800:11800
      - 12800:12800
    environment:
      SW_CORE_RECORD_DATA_TTL: 15
      SW_CORE_METRICS_DATA_TTL: 15
      SW_STORAGE: elasticsearch
      SW_STORAGE_ES_CLUSTER_NODES: elasticsearch:9200
      SW_ENABLE_UPDATE_UI_TEMPLATE: true
      TZ: Asia/Shanghai
      JAVA_OPTS: "-Xms512m -Xmx512m"
  ui:
    image: docker.io/apache/skywalking-ui:9.4.0
    container_name: ui
    depends_on:
      - oap
    restart: on-failure:5
    ports:
      - 18080:8080
    environment:
      SW_OAP_ADDRESS: http://oap:12800
      SW_ZIPKIN_ADDRESS: http://oap:9412

需要注意的是这套对机器配置有一定要求，我一开始使用阿里云的轻量服务器，2c2g很难启动起来

springboot使用java-agent集成skywalking
