This project provides a simple Docker container that utilizes inotifywait to watch for changes in files or directories and trigger a reload of a service when modifications are detected.
Run the container created by this repo together with your application in a single pod with a shared volume. When files at the watched patch are updated the container can send an HTTP request to specified URL or a SIGHUP to specified Service.
- Supports HTTP and SIGHUP reload methods
- Configurable paths to monitor for changes
- Retries HTTP requests with configurable delay
- Logs information about reload attempts and success/failure
