Microservices with Java

Re-engineering microservices with VSCode setup (cos it was build on IntelijIDEA at first)

Architecture

VSCode Setup

Requirement (Extensions):

• Spring Boot Extension Pack.
• Java Extension Pack.

Start Comamnd

Command :

Spring initialzr : Create a (maven/gradle/etc) project

Then setup :

• springboot version
• group
• artifact
• package name
• depedencies

How to Run :

Requirements :

• Localstack

• Docker Desktop

• AWS cli

• LocalStack Create localstack account and get personal auth token

Configure localstack with auth token, leave other settings to default

• Install AWS CLI

Configure aws with :

aws configure

• Create Docker Image With docker compose and Makefile command

• Run Localstack :

./infrastructure/localstack-deploy.sh

Domain should be shown in command:

aws --endpoint-url=http://localhost:4566 elbv2 describe-load-balancers \
    --query "LoadBalancers[0].DNSName" --output text

Run Command

Makefile in each services, Some options :

• make clean
• make build
• make up
• make down

Error Handling

If encounter any error in running script, maybe because depedencies issue :

aws --endpoint-url=http://localhost:4566 cloudformation describe-stack-events --stack-name patient-management --output table

Check error on log table

To Do (?)

Currently hard_coded properties, so there will be .env.example
