Please allow dot in aws_vpn_connection.tunnel*_preshared_key

[saiya]

Hi, I encountered issue caused by validation mismatch between AWS and terraform.
It prevent us from creating aws_vpn_connection.

Could you fix this validation issue?

Terraform Version

Terraform v0.11.6
+ provider.aws v1.14.0

Affected Resource(s)

• aws_vpn_connection

Terraform Configuration Files

resource "aws_vpn_connection" "main" {
  # (snip)

  tunnel1_preshared_key = "example.preshared.key"
  tunnel2_preshared_key = "example.preshared.key"
}

Expected Behavior

Able to use preshared_key that contains dot (".").

Actual Behavior

Got following error, cannot create aws_vpn_connection resource:

Error: module.vpn.aws_vpn_connection.main: "tunnel2_preshared_key" can only contain alphanumeric and underscore characters

I think this behavior is caused by this code: https://github.com/terraform-providers/terraform-provider-aws/blob/master/aws/resource_aws_vpn_connection.go#L571

Steps to Reproduce

• Generate VPN pre-shared key with VPN appliance
• Write aws_vpn_connection resource
• terraform plan

References

AWS official document says:

The PSK must be between 8 and 64 characters in length and cannot start with zero (0). Allowed characters are alphanumeric characters, periods (.), and underscores (_).

The fix for this will be released with v1.22.0 of the AWS provider, middle of this week.

This has been released in version 1.22.0 of the AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
