环境准备

1. 准备一台Centos7虚拟机，分配内存4G（必须，否则启动报错）

2. 安装docker及compose
   

3. 如果compose不是1.27.0，需升级

 curl -L https://get.daocloud.io/docker/compose/releases/download/1.27.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
 docker-compose -v

部署步骤

1. 创建目录

mkdir -p /usr/local/skywalking/
cd /usr/local/skywalking/

2. 编写compose文件

vim docker-compose.yml
# 添加如下内容
version: '3.8'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0
    container_name: elasticsearch
    restart: always
    ports:
      - 9200:9200
    healthcheck:
      test: ["CMD-SHELL", "curl --silent --fail localhost:9200/_cluster/health || exit 1"]
      interval: 30s
      timeout: 10s
      retries: 3

      - TZ=Asia/Shanghai
    ulimits:
      memlock:

      - elasticsearch
    restart: always
    ports:
      - 11800:11800
      - 12800:12800
    healthcheck:
      test: ["CMD-SHELL", "/skywalking/bin/swctl"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 40s
    environment:
      TZ: Asia/Shanghai
      SW_STORAGE: elasticsearch7
      SW_STORAGE_ES_CLUSTER_NODES: elasticsearch:9200
  ui:
    image: apache/skywalking-ui:8.1.0
    container_name: ui
    depends_on:
      - oap
    links:
      - oap
    restart: always
    ports:
      - 8080:8080
    environment:
      TZ: Asia/Shanghai
      SW_OAP_ADDRESS: oap:12800

3. 启动

# 启动
docker-compose up -d 
# 查看日志 无报错启动成功
docker-compose logs -f
