AWS --- aws_network_acl -- subnet_id

[rainmanh]

Hi
using AWS as a privisioner and for the aws_network_acl resource I am trying to associated multiple subnet_id but it does not seem to work, I just get crashes.

subnet_id = ["${var.resource.1}","${var.resource.1}"]

It only seems to work for one:

subnet_id = "${var.resource.1}"

Maybe I am using the wrong syntax for it?

thanks!

Hey @rainmanh – subnet_id is a single entity here; it doesn't accept an array/multiple subnets:

• https://terraform.io/docs/providers/aws/r/network_acl.html

Have you been able to do this elsewhere, with AWS Console or otherwise?

(closing for now, as this is working as documented and according to the AWS API)

Hi
yes, you can do that with the console. you can have several subnet associations per ACL.

http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_ACLs.html

Associating a Subnet with a Network ACL

To apply the rules of a network ACL to a particular subnet, you must associate the subnet with the network ACL. You can associate a network ACL with multiple subnets; however, a subnet can be associated with only one network ACL. Any subnet not associated with a particular ACL is associated with the default network ACL by default.

Hello – I just merged #1931 which provides support for multiple subnet ids, and will go out in the next release.
