A simple custom buildpack for deploying standalone spring-boot maven apps to CF

Custom CloudFoundry BuildPack to Deploy a Maven Spring Boot App

Deploys a maven spring-boot app like the ones created by Spring Initializer to CF. The app is compiled on CF by running maven 'in the cloud' rather than locally on your own machine.

WARNING: This build pack is highly experimental.

How it Works

There are only three bash scripts in this build pack:

• detect: detects whether project contains a pom.xml in the root folder. Fails otherwise
• compile: does the following
  • download and unpack JDK
  • download and unpack maven
  • run mvn package on the project
  • create a 'start.sh' script that runs java -Dserver.port=${VCAP_APP_PORT} -jar <the-jar-maven-built>
• release: tells CF to run start.sh

Using This Buildpack

You can add the buildpack URL in your manfifest.yml file. For example:

---
applications:
- name: flux-boot-hello
  memory: 512M
  host: hello-boot
  buildpack: https://github.com/kdvolder/cf-maven-boot-buildpack.git

Or you can add it as an argument to the cf push command. For example:

cf push flux-boot-hello -b https://github.com/kdvolder/cf-maven-boot-buildpack.git
