Problem
I created a Route 53 zone with the following code:
this.apiV2Zone = new PublicHostedZone(this, "ApiV2", {
zoneName: "api-v2.example.com"
});
The zone was created as expected, but I noticed the TTL
attribute for the NS
record was set to 172800
(2 days).
This is a bit high at the moment, because I'm just experimenting - setting the TTL
lower won't cost me much for now.
But, how do I go about seting the TTL
of the NS
record with the CDK?
What I've tried
I tried to force the NS
record myself with:
let target = RecordTarget.fromValues(
...this.apiV2Zone.hostedZoneNameServers ?? [] );
const recordSet = new RecordSet(this, 'ApiV2Ns', {
recordType: RecordType.NS,
target,
zone: this.apiV2Zone,
deleteExisting: true,
recordName: this.apiV2Zone.zoneName,
ttl: cdk.Duration.minutes(10),
});
But that failed on deploy with:
Received response status [FAILED] from custom resource. Message returned: InvalidChangeBatch
: [A HostedZone must contain at least one NS record for the zone itself.]
Also tried with deleteExisting: false
but that failed too because it was duplicating the existing NS
record.
Workaround
Set it manually in the AWS console. Doesn't seem to cause any change to be reported when I do a CDK diff
.
