Changelog

We have made certain modifications to the official demo, and the following are the specific details of the modifications.

Re-implement components

Adservice

Checkoutservice

  • doesn't depend Emailservice
  • doesn't depend Currencyservice
  • doesn't depend Kafka

Added components

Dataservice

This service only used by Adservice. It will accept Adservice's http request then response Ad data from mysql.

Official chart re-configuration

  1. Close all none business services, such as Opentelemetry collector, Prometheus, Jaeger, Grafana, all service's telemetry data will fellow this data flow: Components --> Insight-agent OTel collector。

  2. Support deploying Redis instance from a Redis operator(Make sure Redis operator already works).

Install

Note：make sure Insight agent already works(If--set .global.middleware.redis.deployBy=redisCR, make sure Redis operator already works)

helm repo add open-insight https://openinsight-proj.github.io/openinsight-helm-charts

helm install webstore-demo open-insight/opentelemetry-demo-lite -n webstore-demo --create-namespace

Common chart param

Please use values.schema.json to get to know how to control the deployment behavior of this chart(use json schema editor to parse the schema and use json-to-yaml to generate values.yaml).
