blockchain-java's Introduction

BlockChain Demo

This is a Block Chain Demo Application

Development

To start your application in the dev profile, simply run:

./gradlew :chain-core:bootRun

Building for production

To optimize the blockchain demo application for production, run:

./gradlew :demo-web:clean :demo-web:bootJar

To ensure everything worked, run:

java -jar -Dspring.profiles.active=prod demo-web/build/libs/*.jar

Testing

To launch your application's tests, run:

./gradlew :chain-core:test

Using Docker to simplify development (optional)

You can also fully dockerize your application and all the services that it depends on. To achieve this, first build a docker image of your app by running:

chain-core

docker build --build-arg JAR_FILE=chain-core/build/libs/\*.jar -t hibuz/chain-core -f chain-core/Dockerfile .

demo-web

docker build --build-arg JAR_FILE=demo-web/build/libs/\*.jar -t hibuz/demo-web -f demo-web/Dockerfile .

You can also dockerize in the subfolder

cd demo-web
docker build -t hibuz/demo-web .

Then run:

chain-core

docker run --rm -p 6565:6565 hibuz/chain-core

demo-web

docker run --rm --network host hibuz/demo-web

To use Github Container Registry`s arm64 image with prod profile, run:

docker run --rm -e "SPRING_PROFILES_ACTIVE=prod" -p 8080:8080 ghcr.io/hibuz/demo-web

Rest APIs

blockchain-java's Issues

안녕하세요 Team Ainize입니다.

Ainize를 통해 배포해주신 blockchain-java프로젝트가 현재 다음과 같은 에러메세지를 보이며 container가 시작되지 않고 있습니다.
아마 다른 서버에 접속하는 로직에서 문제가 발생한 것으로 보이는데요. 디버깅에 참고가 되었으면 합니다.
