edmur/dns-updater repository overview

⁠dns-updater

Updates your DNS records on your DNS provider when it changes.

⁠About

This project is a PHP utility used to update DNS Records on multiple DNS providers. It is basically used to keep an DNS "A" Record in sync with your public IP automatically, on any provider.

Currently available providers are:

• Cloudflare
• DigitalOcean

⁠Usage

This tool does not ensure that your configurations are correct. Configure your DNS settings correctly on your provider first, and use this tool only to keep the record updated.

This will run the project on a schedule (every 5 mins) by default. Just run the following command and you are good to go (refer tothe environment variables definitions in the section below).

docker run --name dns-updater-mysite-ddns \
--env PROVIDER=cloudflare \
--env [email protected];my-api-key-here \
--env DOMAIN=mysite.com \
--env RECORD=ddns \
--restart unless-stopped \
edmur/dns-updater

docker logs dns-updater-mysite-ddns
