architecture

Request Routing

Provided proxy.target-url=http://localhost:8081/data
GET http://localhost:8088/proxy/info -> GET http://localhost:8081/data/info

Build and run

Provide your configuration file based on this example. Set proxy.target-url accordingly.

gradle clean build test
java -jar build/libs/spring-proxy-1.0.0-SNAPSHOT.jar --spring.config.location=file:./src/main/resources/application.yml

Build Docker Image

Docker files for x86_64 and ARM armv7l/aarch64 architectures are available. This example shows how to build docker image for x86_64 architecture.

docker build -t spring-proxy-x86:1.0.0-SNAPSHOT --file Dockerfile.x86_64 .
docker image list
docker save --output="build/spring-proxy-x86:1.0.0-SNAPSHOT.tar" spring-proxy-x86:1.0.0-SNAPSHOT
docker image rm -f <imageid>
docker run -p 8081:8081 spring-proxy-x86:1.0.0-SNAPSHOT

Full stack docker-compose demo

Use docker-compose to run complete stack:

  1. spring-proxy on localhost:8088
  2. spring-demo on localhost:8081
docker-compose up --build -d
curl http://localhost:8081/data/info # <- direct call of target service
curl http://localhost:8088/proxy/info # <- call target service via proxy
gradle clean test -Dtest.profile=integration
docker-compose down -v --rmi all --remove-orphans
