* 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
|
||
|
|
|
||
|
|
#+begin_src shell
|
||
|
|
r53 -zone ZONEID [-ttl SECONDS] <domain>...
|
||
|
|
#+end_src
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
