infrastructureascode/route53-presence

Docker container which registers the local EC2 instance into Route53.

This is a fork of timelinelabs/docker-route53-presence which doesn't have a Docker Hub repo. I have updated the script so that it can handle hostnames with 3rd-level domains (i.e. host.subdomain.example.com). I have sent a pull request to get the change incorporated, but decided to roll on my own given that repo hasn't been updated since March 2014.

docker run --rm infrastructureascode/route53-presence -h
usage: route53-presence [-h] [--ttl TTL] [--local] hostname

Register or unregister a name in Route53.

positional arguments:
  hostname    fqdn to manipulate

optional arguments:
  -h, --help  show this help message and exit
  --ttl TTL   ttl in seconds, default 600
  --local     use local IP instead of public

Example Usage

# Passing AWS keys as environment variables
docker run --name route53-presence  \
    -e AWS_ACCESS_KEY=XXX \
    -e AWS_SECRET_KEY=XXX \
    infrastructureascode/route53-presence \
        --ttl=300 \
        host.subdomain.example.com

# Omitting AWS keys if the EC2 instance has a role that allows Route 53 actions. See below.
docker run --name route53-presence  \
    infrastructureascode/route53-presence \
        --ttl=300 \
        host.subdomain.example.com

AWS IAM Role

The AWS credentials can be omitted if the host has a valid IAM role that allows for the following permissions:
