Dynamic DNS using DigitalOcean's DNS Services

A script that pushes the public IP address of the running machine to DigitalOcean's DNS API's. It requires an existing A record to update.

Setup

Assuming you already have a DigitalOcean account and your domain associated with it. Just add an A record with desired name and IP address. That's it!

Usage

Pick one of the options below using the following settings:

• DIGITALOCEAN_TOKEN: The token you generate in DigitalOcean's API settings.
• DOMAIN: The domain your subdomain is registered at. (i.e. foo.com for home.foo.com)
• NAME: Subdomain to use. (name in A record) (i.e. home for home.foo.com)
• SLEEP_INTERVAL: Polling time in seconds. (default: 300)

Docker (Recommended)

$ docker pull tunix/digitalocean-dyndns
$ docker run -d --name dyndns \
  -e DIGITALOCEAN_TOKEN="your_token_here" \
  -e DOMAIN="yourdomain.com" \

  -e SLEEP_INTERVAL=2 \
  tunix/digitalocean-dyndns
