The purpose of this container is to update DNS zone records using Gandi's LiveDNS (http://doc.livedns.gandi.net/) with your WAN IP.

This image is extremely lightweight (Alpine Linux based) and has very few dependencies. The actual DNS update program is coded in shell script only.

Warning : update scripts have been updated to use Gandi's Personal Access Tokens (PATs).

You need to create a new Personal Access Token for this application, with at least the "Manage domain name technical configurations" premissions. See https://api.gandi.net/docs/authentication/

Mandatory variables:

• GANDI_PAT: your Gandi Personal Acces Token (be sure to enable "Manage domain name technical configurations")
• APIKEY: deprecated provided for backward compatibility. Value will be used as GANDI_PAT if provided
• DOMAIN: your Gandi domain
• RECORD_LIST: DNS records to update separated by ";"

Optional variables :

• REFRESH_INTERVAL: Delay between updates in seconds (default: 10mn)
• TTL: Set Time To Live for records (default: 300)
• SET_IPV4: Update A record (default: yes)
• SET_IPV6: Update AAAA record (default: no)
• FORCE_IPV4: Force the IPv4 address to be used in DNS A records
• FORCE_IPV6: Force the IPv6 address to be used in DNS AAAA records

The easiest way to run gandi-livedns is simply to docker run it from a computer in your network, leaving it running in the background with all the default settings.

docker run -d \
	-e "GANDI_PAT=<YOUR_VERY_SECRET_PERSONAL_ACCESS_TOKEN>" \
	-e "RECORD_LIST=blog;www;@" \
	-e "DOMAIN=your-gandi-hosted-domain.com" \
	jbbodart/gandi-livedns

This will update blog.your-gandi-hosted-domain.com, www.your-gandi-hosted-domain.com, and your-gandi-hosted-domain.com with your internet-facing IP (IPv4) every 10 minutes

An equivalent setup using docker-compose could look like this:
docker-compose.yml

version: '3.7'
...
    services:
    ...
        dyndns:
            image: jbbodart/gandi-livedns
            restart: unless-stopped
            env_file:
                - "dyndns.env"

dyndns.env
