inotifywait-reloader's Introduction

What?

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.

How?

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.

Features

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
