Question

I m using `awsx ec2 Vpc` to generate a VPC across two availability zones ``` const vpc = new awsx ec2 Vpc `$ shortName nameConfig vpc` availabilityZoneNames zoneName albSecondZoneName cidrBlock 10 0 0 0 16 enableDnsHostnames true tags name `$ shortName nameConfig vpc` subnetSpecs type awsx ec2 SubnetType Public cidrMask 22 type awsx ec2 SubnetType Private cidrMask 20 ``` How do I get the public subnet for the availability zone `zoneName` to launch an EC2 instance in This seems like it should be easy but the examples all just choose the first public subnet ID which isn t correct There is `vpc subnets` but checking `tagsAll` and `availabilityZone` inside `subnets apply ` doesn t seem to work it appears `tagsAll apply ` and `availabilityZone apply ` don t block

Hmm maybe I have it working Surely there is a better way than this though ``` let subnet = vpc subnets apply subnets = gt for const sn of subnets let tagsCorrect = sn tagsAll apply tags = gt if tags SubnetType === Public return true else return false let availabilityZoneCorrect = sn availabilityZone apply az = gt if az === zoneName return true else return false if availabilityZoneCorrect amp amp tagsCorrect return sn else console log Did not find subnet return null ```

There s a `publicSubnetIds` and `privateSubnetIds` output on the VPC component I believe they ll get generated in order so your first AZ supplied should be the first ID in each subnetIds
