This project demonstrate how to leverage Service Mesh Layer in Microservice Architecture.

Build:

1. Build docker images locally

   ./gradlew clean jibDockerBuild

   or build and push docker images to configured $dockerRepository

   ./gradlew clean jib

Build separate service

./gradlew clean :order-service:jib -x test

Run using docker-compose:

1. Up and run docker containers with all the business and technical services

   cd docker && docker-compose up -d --scale order-service=2 --scale user-service=2

2. Test "get orders" endpoint works (request chain: api-gateway -> linkerd -> order-service -> linkerd -> user-service

   curl -v http://localhost:8070/order-service/api/orders

One-liner Run:

./gradlew clean jibDockerBuild && cd docker && docker-compose up -d --remove-orphans --scale order-service=2 --scale user-service=2

Stop:

cd docker && docker-compose stop

Run using Kubernetes cluster

1. Install order-service

   cd order-service && helm install order-service ./chart

   Uninstall order-service

   cd order-service && helm uninstall order-service

2. Install user-service

   cd user-service && helm install user-service ./chart

   Uninstall order-service

   cd user-service && helm uninstall user-service

3. Install all MSA infra

   helm install msa-infra ./msa-infra-chart

   Uninstall all MSA infra

   helm uninstall msa-infra
