1、安装docker 、安装 docker-compose 

这里不再赘述

2、新建文件 app.yml, 内容如下

version: '3'
services:
  postgresql12_pg:
    image: postgres:12.1
    container_name: postgresql12_pg
    restart: always
    environment:
      POSTGRES_USER: "facedb"
      POSTGRES_PASSWORD: "facedb123"
      POSTGRES_DB: "facedb"
    volumes:
      - /data_master/postgresql12_pg_similarity/data:/var/lib/postgresql/data
      - /opt/FaceService:/opt/FaceService
      - /etc/localtime:/etc/localtime:ro
    network_mode: "host"
    

3、创建 postgresql 数据库

docker-compose -f app.yml up -d postgresql12_pg
