youarehere 1.0.0

Route53 DNS utility

you are here 🌎

Somehow, adding a new record to Route53 takes 100 lines of Python. So now it only takes one.

>>> from youarehere import create_record
>>> create_record("A", "foo.example.com", "4.4.4.4")

You can also easily point a record to the current machine:

>>> from youarehere import point_record_to_here
>>> point_record_to_here("foo.example.com")

use case

You have a Raspberry Pi that travels around and you want to keep a pointer to it in Route53. Add this as a cron-job:

$ python3 -c "point_record_to_here('my-pi.example.com')"

create_record Arguments

Argument	Type	Default	Description
record_type	str		The type of the record to add (e.g. A, CNAME, etc). For an exhaustive list, see youarehere.VALID_RECORD_TYPES.
name	str		The DNS record name (e.g. "foo.example.com")
destination	str / List[str]		The destination IP or values (e.g. ["4.4.4.4", "8.8.8.8"]). If you provide a single string, it will be treated as an Array[1].
hosted_zone_id	str	None	ID of the hosted zone to which to add this record. Guess automatically by default, or use youarehere.guess_hosted_zone_id_for_name.
comment	str	""	An optional comment for the change request (e.g. "Baby's first DNS record!")
ttl	int	300	The TTL for your record; defaults to 300 which is probably too low.
