r53
r53 is a dynamic DNS client for AWS Route 53. It queries the host's
public IPv4 and IPv6 addresses via OpenDNS (falling back to Google) and
upserts the corresponding A and AAAA records for each domain.
Usage
r53 -zone ZONEID [-ttl SECONDS] <domain>...Flags:
-zone— Route 53 hosted zone ID (required)-ttl— TTL of the DNS records in seconds (default: 300)
Arguments:
<domain>— one or more domain names to update
r53 requires the dig command and AWS credentials from the SDK default
chain (environment, shared config, or IMDS).
On success the command writes nothing to stdout; it logs the Route 53
response for each domain to stderr at debug level.
Examples
$ r53 -zone Z1234567890EXAMPLE example.com www.example.com
