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. The resulting container image is roughly around 7 MB (thanks to Alpine Linux).
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!
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
forhome.foo.com
) - NAME: Subdomain to use. (name in A record) (i.e.
home
forhome.foo.com
). Multiple subdomains must be separated by semicolons;
- SLEEP_INTERVAL: Polling time in seconds. (default: 300)
$ docker pull tunix/digitalocean-dyndns
$ docker run -d --name dyndns \
-e DIGITALOCEAN_TOKEN="your_token_here" \
-e DOMAIN="yourdomain.com" \
-e NAME="subdomain" \
-e SLEEP_INTERVAL=2 \
tunix/digitalocean-dyndns
You can also create a cronjob using below command:
$ DIGITALOCEAN_TOKEN="your_token_here" DOMAIN="yourdomain.com" NAME="subdomain" SLEEP_INTERVAL=2 ./dyndns.sh
