Note

A GitHub Action that push a new monthly image has been setup only to always have the latest Alpine base image

A simple but effective containerized implementation of my script (visible at this link) to update the Dynamic Public IP utilizing the OVH DDNS Service DynHost.

Environment Variables

Variable	Description
HOSTNAME	OVH domain
LOGIN	DynHost username
PASSWORD	DynHost password
LOG_TYPE	Values can be either 'file' or 'STDOUT'. Nothing else is accepted. Default is 'STDOUT'.
REFRESH_TIME	Must be a positive integer in minutes. Script runs every REFRESH_TIME minutes. Default is 5.

Supported architectures

Architecture	Supported?
x86	YES
x86_64	YES
armv7	YES
aarch64	YES

Locally build the image

The image is available in the GitHub Container Registry, but if you want to locally build it in order to debug, or improve or whatever, just modify the docker compose substituting the line image: with:

    build:
      context: .
      dockerfile: Dockerfile
    image: ovh-ddns:local-build

Extra: Create a DynHost user from OVH Control Panel

From OVH dashboard you can create the DynHost user:

1. Domain names/yourdomain.ovh/DynHost section
2. Manage Access
3. Create a username and the subdomain you wanna redirect the host
4. Then Add a DynHost record with the same subdomain and the current IP of the host

Remember that for some TLD, redirection to domain.TLD is not possible (ie .it doesn't allow this, so if I need to redirect to a domain.it, I'd create dyn.domain.it and redirect to it. Then I'll redirect any subdomain to dyn.domain.it and I have my Nginx reverse proxy that listen for dyn.domain.it)
