Docker安装skywalking

1、安装说明

首先需要安装docker-compose，不会安装的可以翻之前的博客

参考地址：https://github.com/apache/skywalking/tree/master/docker

修改项：

1、容器时区都改成了北京时间

2、depends_on存在问题，已经做了处理使用 docker-compose up -d 服务名 的方式等待上一个启动成功了再进行启动

3、镜像版本进行升级

2、操作

1、创建docker-compose.yml文件，文件内容如下

version: '3.8'
services:
  es:
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:7.4.2
    container_name: es
    ports:
      - "9200:9200"
    healthcheck:
      test: [ "CMD-SHELL", "curl --silent --fail localhost:9200/_cluster/health || exit 1" ]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 10s
    environment:
      - discovery.type=single-node
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "TZ=Asia/Shanghai"
    ulimits:
      memlock:
        soft: -1
        hard: -1

  oap:
    image: apache/skywalking-oap-server:8.9.1
    container_name: oap
    depends_on: 
      - es
    links:
      - es
    ports:
      - "11800:11800"
      - "12800:12800"
    healthcheck:
      test: [ "CMD-SHELL", "/skywalking/bin/swctl ch" ]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 10s
    environment:
      SW_STORAGE: elasticsearch
      SW_STORAGE_ES_CLUSTER_NODES: es:9200
      SW_HEALTH_CHECKER: default
      TZ: Asia/Shanghai
      SW_TELEMETRY: prometheus
      JAVA_OPTS: "-Xms2048m -Xmx2048m"

  ui:
    image: apache/skywalking-ui:8.9.1
    container_name: ui
    depends_on: 
      - oap
    links:
      - oap
    ports:
      - "8080:8080"
    environment:
      SW_OAP_ADDRESS: http://oap:12800
      TZ: Asia/Shanghai

2、依次启动

docker-compose up -d es
docker-compose up -d oap
docker-compose up -d ui
