OVHCloud

DynHost

This is a lightweight service that automatically updates your public IP address with OVHCloud DynHost every hour. It's useful for maintaining up-to-date DNS records when using a dynamic IP address (e.g., for home servers or remote access). The service runs via Docker and provides simple HTTP endpoints for manual control and monitoring.

Prerequisite

• Docker Desktop

Installation

1. Download and open docker-compose-dynhost.yml.
2. Update the following environment variables with your OVHCloud DynHost credentials and hostnames:

- "DynHostSettings__HostNames__0=Test"
- "DynHostSettings__Username=Username"
- "DynHostSettings__Password=Password"

3. From the root of this repository, run the app using Docker Compose:

docker compose -f docker-compose-dynhost.yml

Usage

Once running, the service will automatically push your current IP address to OVHCloud every hour.

You can also interact with the following endpoints:

• View IP Address Status
  Returns the current public IP and the last saved IP sent to OVHCloud:
  http://localhost:6500/IpAddress

• Trigger Immediate IP Check
  Forces an immediate check and update of your IP address, skipping the hourly schedule:
  http://localhost:6500/TriggerIpAddressCheck

• Reset Cache and Force Update
  Clears the cached IP address and ensures your current IP is sent during the next check:
  http://localhost:6500/ResetIpAddressCheck
