+# Infisical ↔ Dokploy Bridge
+
+A Spring Boot (Java 21) application acting as a secure bridge between Infisical and Dokploy, enabling automated synchronization and deployment of secrets through APIs and webhooks.
+
+## Features
+
+- Secure integration with Infisical
+- Automated updates via Dokploy API
+- Webhook-driven synchronization
+- Docker and Docker Compose ready
+
+## Architecture Overview
+
+Infisical  
+↓ (Webhook / API)  
+Infisical–Dokploy Bridge (Spring Boot)  
+↓ (Dokploy API)  
+Dokploy  
+
+## Requirements
+
+- Java 21
+- Docker and Docker Compose
+- Infisical account
+- Dokploy instance with API access
+
+## Environment Variables
+
+### Infisical
+
+- INFISICAL_API_URL: Base URL of Infisical API
+- INFISICAL_CLIENT_ID: Infisical service client ID
+- INFISICAL_CLIENT_SECRET: Infisical service client secret
+- INFISICAL_WEBHOOK_SECRET: Webhook signature validation secret
+
+### Dokploy
+
+- DOKPLOY_API_URL: Base URL of Dokploy API
+- DOKPLOY_API_KEY: Dokploy API key
+
+## Docker Compose
+
+```txt
+services:
+  infisical-bridge:
+    build: .
+    restart: always
+    environment:
+      INFISICAL_API_URL: ${INFISICAL_API_URL}
+      INFISICAL_CLIENT_ID: ${INFISICAL_CLIENT_ID}
+      INFISICAL_CLIENT_SECRET: ${INFISICAL_CLIENT_SECRET}
+      INFISICAL_WEBHOOK_SECRET: ${INFISICAL_WEBHOOK_SECRET}
+      DOKPLOY_API_URL: ${DOKPLOY_API_URL}
+      DOKPLOY_API_KEY: ${DOKPLOY_API_KEY}
+```
+
+## Running
+
+With Docker Compose:
+
+```sh
+docker compose up -d --build
+```
+
+Local development:
+
+```sh
+./gradlew bootRun
+```
+
+Application runs on http://localhost:8080
+
+Use a service like ngrok.
+
+## Infisical Webhook Configuration
+
+When creating a webhook in Infisical, the following rules must be respected.
+
+### Webhook URL Formats
+
+Infisical bridge supports two webhook URL formats, depending on the Dokploy resource you want to update.
+
+#### Dokploy Compose Webhook
+
+`${INFISICAL_API_URL}/webhook?dokployComposeId=${DOKPLOY_COMPOSE_ID}`
+
+Parameters:
+- dokployComposeId (required):
+  The identifier of the target Dokploy Compose.
+  This value is used to determine which Dokploy compose service should be updated when the webhook is triggered.
+
+#### Dokploy Application Webhook
+
+`${INFISICAL_API_URL}/webhook?dokployApplicationId=${DOKPLOY_APPLICATION_ID}`
+
+Parameters:
+- dokployApplicationId (required):
+  The identifier of the target Dokploy Application.
+  This value is used to determine which Dokploy application should be updated when the webhook is triggered.
+
+#### Notes
+- Exactly one identifier must be provided per webhook URL.
+- If no identifier or multiple identifiers are provided, the webhook request will be rejected.
+- Ensure the provided ID matches an existing Dokploy resource.
+
+### Webhook Secret
+
+The webhook secret **must exactly match**:
+
+`${INFISICAL_WEBHOOK_SECRET}`
+
+Requests with an invalid or missing secret will be rejected.
+
+## Webhooks Behavior
+
+- Incoming webhook signatures are validated
+- Secrets are fetched from Infisical
+- Dokploy is updated using its API
+- Invalid or unsigned requests are ignored
+
+## Security Notes
+
+- Secrets are never persisted
+- Configuration is environment-driven
+- HTTPS is recommended in production
+- Restrict network access to trusted sources only
+
+## Testing
+
+```sh
+./gradlew test
+```
+
+## Tech Stack
+
+- Java 21
+- Spring Boot
+- Gradle (Kotlin DSL)
+- Docker / Docker Compose
