部署步骤

环境准备

  1. 创建dynamodb 表
## ProductDetails 商品表-英文
aws dynamodb create-table \
  --table-name ProductDetails \
  --attribute-definitions AttributeName=ProductID,AttributeType=S \
  --key-schema AttributeName=ProductID,KeyType=HASH \
  --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

## ProductDetailsCN 商品表-中文
aws dynamodb create-table \
  --table-name ProductDetailsCN \
  --attribute-definitions AttributeName=ProductID,AttributeType=S \
  --key-schema AttributeName=ProductID,KeyType=HASH \
  --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

## ProductReviews 商品评论表-英文
aws dynamodb create-table \
  --table-name ProductReviews \
  --attribute-definitions AttributeName=ProductID,AttributeType=S AttributeName=Timestamp,AttributeType=N \
  --key-schema AttributeName=ProductID,KeyType=HASH AttributeName=Timestamp,KeyType=RANGE \
  --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

## ProductReviewsCN 商品评论表-中文
aws dynamodb create-table \
  --table-name ProductReviewsCN \
  --attribute-definitions AttributeName=ProductID,AttributeType=S AttributeName=Timestamp,AttributeType=N \
  --key-schema AttributeName=ProductID,KeyType=HASH AttributeName=Timestamp,KeyType=RANGE \
  --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5
  1. 准备opensearch 集群 创建opensearch集群，并为控制面板配置Amazon Cognito 身份验证
  1. 申请bedrock model

基础数据导入

导入商品信息

## 英文产品信息
aws dynamodb put-item \
  --table-name ProductDetails \
  --item product_en.json

## 中文产品信息
aws dynamodb put-item \
  --table-name ProductDetailsCN \
  --item product_cn.json

创建dynamodb 到 Opensearch zero-ETL pipeline

  1. 注册opensearch ML model
# 1. 创建bedrock ml connector

  1. 验证数据摄入 Alt text

部署lambda 及 Apigateway

  1. 部署lambda function 创建lambda function,复制代码进行部署 lambda_handler_bedrock.py 及 lambda_handler_product.py
  2. 部署apigateway
  • 代理POST 请求到lambda_handler_bedrock.py
  • 代理GET&POST请求到lambda_handler_product.py

部署前端UI

  1. 下载前端代码，front目录下，修改 front/src/APP.vue 192行，替换url 为APIgateway URL const APIURL = ''
  2. 安装依赖编译运行
  • 本地运行
npm install
npm run serve
  • 编译
npm install
npm run build
  1. 验证前端UI Alt text
