Amazon Route53 Dynamic DNS Tool

A simple dynamic DNS service for Route53.

Retrieving your external IP

This service performs a DNS query to retrieve your IP address from an OpenDNS resolver. This method arguably faster and more reliable than using an http(s) service.

Similar functionality could be done via the shell using dig: dig +short myip.opendns.com @resolver1.opendns.com;

It now supports the ability to set multiple A records (including a wildcard) your WAN IP address.

Usage

docker run -d \
    --name route53 \
    -e AWS_ACCESS_KEY_ID= \
    -e AWS_SECRET_ACCESS_KEY= \
    -e AWS_CONNECTION_REGION=us-east-1 \
    -e ROUTE53_DOMAIN_A_RECORDS= \
    -e ROUTE53_UPDATE_FREQUENCY=10800 \
    -e ROUTE53_RECORD_TTL=300 \
    bradqwood/route53-dyndns
