+
+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
+```bash
+./gradlew clean build
+```
+
+### Run the application
+```bash
+./gradlew bootRun
+```
+
+Or run the JAR directly:
+```bash
+java -jar build/libs/cf-uploader-1.0.0.jar
+```
+
+The application will start on `http://localhost:8080`
+
+## API Endpoint
+
+### 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
+
+```bash
+curl -X POST http://localhost:8080/api/cf/deploy \
+  -F 'request={
+    "apiEndpoint": "https://api.cf.example.com",
+    "username": "your-username",
+    "password": "your-password",
+    "organization": "your-org",
+    "space": "your-space",
+    "appName": "my-app",
+    "skipSslValidation": false
+  }' \
+  -F 'jarFile=@/path/to/your/application.jar' \
+  -F 'manifest=@/path/to/manifest.yml'
+```
+
+### Sample Request with Skip SSL Validation
+
+```bash
+curl -X POST http://localhost:8080/api/cf/deploy \
+  -F 'request={

+    "skipSslValidation": true
+  }' \
+  -F 'jarFile=@./sample-app.jar' \
+  -F 'manifest=@./manifest.yml'
+```
+
+### Sample Manifest File (manifest.yml)
+
+```yaml

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

+## Response Format
+
+### Success Response
+
+```json
+{
+  "success": true,
+  "message": "Application deployed successfully",
+  "deploymentId": "123e4567-e89b-12d3-a456-426614174000",
+  "output": "CF CLI output logs...",
+  "error": null
+}
+```
+
+### Error Response
+
+```json
+{
+  "success": false,
+  "message": "Application deployment failed",
+  "deploymentId": "123e4567-e89b-12d3-a456-426614174000",
+  "output": "CF CLI output logs...",
+  "error": "Error details..."
+}
+```
+
+## Configuration
+
+Application settings can be configured in `src/main/resources/application.properties`:
+
+```properties
+# Server port
+server.port=8080
+
+# Max file size (default: 500MB)
+spring.servlet.multipart.max-file-size=500MB
+spring.servlet.multipart.max-request-size=500MB
+
+# CF CLI timeout in seconds (default: 600)
+cf.cli.timeout=600
+
+# Optional: Custom CF CLI path (if not using bundled binaries)
+cf.cli.path=
+```
+
+## Features
+
+- RESTful API for CF deployments
+- Automatic CF CLI binary management (Linux, macOS, Windows)
+- Secure password handling (masked in logs)
+- Configurable timeout for long-running deployments
+- Comprehensive error handling
+- Multipart file upload support up to 500MB
+- Automatic cleanup of temporary files
+
+## Error Handling
+
+The API handles various error scenarios:
+- **400 Bad Request**: Invalid request parameters or file validation errors
+- **413 Payload Too Large**: Files exceed 500MB limit
+- **500 Internal Server Error**: Deployment failures or unexpected errors
