manycast-dns

manycast-dns is a tool to simplify the parallel management of multiple cloud anycast DNS providers.

Because even major anycast DNS providers with 100% uptime SLAs can suffer outages, the only way to improve reliability is to spread your DNS over multiple anycast networks. This tool is meant to provide a minimal command line interface for provisioning and updating DNS across multiple cloud providers.

Dependencies / Supported clouds

• dnspython
• boto3 / Amazon Web Services Route 53
• google-cloud-dns / Google Cloud Platform DNS

Configuring

[google-cloud-platform]
; Google will provide this json file when creating an API user
json-credentials-file = config/google-cloud-credentials.json
project-id = principal-rhino-147203

[amazon-web-services]
access-key-id = ...
secret-access-key = ...

Example usage

# Provisioning Google Cloud from AWS
./manycast-dns provision whatbox.ca amazon-web-services google-cloud-platform

# Upserting SOA records
# These don't make a lot of sense with our approach, but they're still required. Each server must have any single valid server
# followed by an email with the @ replaced with a dot to contact, and various tuning parameters.
