CF Deployer - Cloud Foundry Deployment Service

A Spring Boot application that provides a REST API for deploying Java applications to Cloud Foundry/Tanzu environments.

Prerequisites

• Java 21
• Gradle 8.14

Build and Run

Build the application

./gradlew clean build

Run the application

./gradlew bootRun

Or run the JAR directly:

java -jar build/libs/cf-uploader-1.0.0.jar

The application will start on http://localhost:8080

API Endpoints

1. Deploy Application to Cloud Foundry

Endpoint: POST /api/cf/deploy

Content-Type: multipart/form-data

Request Parts:

• request (JSON string): Deployment configuration
• jarFile (file): The Java application JAR file
• manifest (file): Cloud Foundry manifest.yml file

Sample cURL Request

Sample Manifest File (manifest.yml)

---
applications:
- name: sample-app
  memory: 1G
  instances: 2
  path: sample-app.jar
  buildpacks:
  - java_buildpack
  env:
    SPRING_PROFILES_ACTIVE: production

Common Request Parameters

All endpoints require the following CF credentials and target information:

Field	Type	Required	Description
apiEndpoint	String	Yes	Cloud Foundry API endpoint URL
username	String	Yes	CF username
password	String	Yes	CF password
organization	String	Yes	Target CF organization
space	String	Yes	Target CF space
appName	String	No*	Application name (required only for /deploy endpoint)
skipSslValidation	Boolean	Yes	Skip SSL certificate validation

Note: Even though appName is not used by utility endpoints (/apps, /routes, /app/{appName}, /logs/{appName}), it must still be included in the JSON request body (can be empty string). The organization and space determine which apps/routes are listed or queried.
