# route53 is similar to sdbadmin for Route53, it's a simple
|
|
# console utility to perform the most frequent tasks with Route53
|
|
#
|
|
# Example usage. Use route53 get after each command to see how the
|
|
# zone changes.
|
|
#
|
|
# Add a non-weighted record, change its value, then delete. Default TTL:
|
|
#
|
|
# route53 add_record ZPO9LGHZ43QB9 rr.example.com A 4.3.2.1
|
|
# route53 change_record ZPO9LGHZ43QB9 rr.example.com A 9.8.7.6
|
|
# route53 del_record ZPO9LGHZ43QB9 rr.example.com A 9.8.7.6
|
|
#
|
|
# Add a weighted record with two different weights. Note that the TTL
|
|
# must be specified as route53 uses positional parameters rather than
|
|
# option flags:
|
|
#
|
|
# route53 add_record ZPO9LGHZ43QB9 wrr.example.com A 1.2.3.4 600 foo9 10
|
|
# route53 add_record ZPO9LGHZ43QB9 wrr.example.com A 4.3.2.1 600 foo8 10
|
|
#
|
|
# route53 change_record ZPO9LGHZ43QB9 wrr.example.com A 9.9.9.9 600 foo8 10

|

|
|
# their TTLs from the backing ELB:
