Reactive Security

A simple demo application showcases reactive security.

Technology stack

• Spring Framework 5
• Spring Boot 2.0.0
• Spring WebFlux
• Gradle 4

Highlights

• Multi-project builds with Gradle Kotlin Script.
• Kotlin as a language
• Cross-Origin Resource Sharing (CORS)
• Docker deployment

Prerequisites

1. Gradle 4 (Install via sdkman)
2. Docker for Mac Setup Instructions

Build

# build all 3 executable jars
gradle build
# continuous build with `-t`. 
# this shoud be started before any run tasks i.e., `gradle ui-app:bootRun`, for spring's devtools to work.
gradle -t build
# build all 3 apps
gradle build -x test -x shared:build
# build all 3 docker images
gradle docker -x test -x shared:build

Test

gradle test

Run

Manual

Start all 3 apps: data-service, auth-service, jwt-client

If you want to debug the app, add --debug-jvm parameter to Gradle command line

Docker

You can also build Docker images and run all via Docker Compose

# start containers in the background
docker-compose up -d
# start containers in the foreground
docker-compose up 
# show runnning containers 
docker-compose ps
# scaling containers and load balancing
docker-compose scale data-service=2
# 1. stop the running containers using
docker-compose stop
# 2. remove the stopped containers using
docker-compose rm -f
# start specific docker-compose file
docker-compose  -f docker-compose-all.yml up
# just start only a single service
docker-compose up mysql
# connect(ssh) to a service and run a command
docker-compose exec  mysql mysql --user=root --password demo
