DynDNS update script for OVH domains

this is based on ovh-dyndns from Ambroisemaupate work and forked from webhainaut repository to add multiple domain update

https://docs.ovh.com/fr/domains/utilisation-dynhost/

Check every 5 minutes you WAN IP and if changed call OVH entry-point to update your DynDNS domains.

you can set as many $HOSTX as you want, starting from 1 and incrementing if you need separate login and password, you can set LOGINX and PASSWORDX to match the host, if no LOGINX is fount it fallback to LOGIN and PASSWORD

docker run -d --name="ovhdyndnsdocker" \
    -e "HOST1=mydynamicdomain.domain.com" \
    -e "LOGIN=mylogin" \
    -e "PASSWORD=mypassword" \
    ambroisemaupate/ovh-dyndns

Customize external NS server

By default, we use Google DNS to check your current DynDNS IP, but you can choose an other DNS overriding NSSERVER env var:

docker run -d --name="ovhdyndnsdocker" \
    -e "HOST1=mydynamicdomain.domain.com" \
    -e "LOGIN=mylogin" \
    -e "PASSWORD=mypassword" \
    -e "NSSERVER=192.168.1.1" \
