Terraform CLI and Terraform AWS Provider Version

Terraform: 1.1.7
AWS Provider Version: 4.5.0

Affected Resource(s)

• aws_ec2_client_vpn_authorization_rule
• aws_ec2_client_vpn_route

Terraform Configuration Files

resource "aws_ec2_client_vpn_authorization_rule" "remote" {
  for_each               = { for role in local.roles : "${role.role}-${role.cidr}" => role }
  client_vpn_endpoint_id = aws_ec2_client_vpn_endpoint.vpn.id
  target_network_cidr    = each.value.cidr
  access_group_id        = each.value.role
  description            = "${each.value.role}-${each.value.cidr}"
}

resource "aws_ec2_client_vpn_route" "route_1" {
  for_each               = toset(var.peer_cidrs)
  client_vpn_endpoint_id = aws_ec2_client_vpn_endpoint.vpn.id
  destination_cidr_block = each.value
  target_vpc_subnet_id   = tolist(module.base_infrastructure_state.private_subnet_ids)[0]
}

Expected Behavior

Resources would be created/deleted cleanly. Timeout needs to be raised on these resources to 2 minutes or more. This can be done in hcl, but the default should be increased.

Actual Behavior

The timeout on these resources is hard coded to 1m. In my tests, creating and destroying these resources can take anywhere from 50-75 seconds. So about half the time the transaction fails. Which results in tainted resources that have to be destroyed and created again. When you have a number of routes/auth rules, this basically can never complete successfully.

Steps to Reproduce

1. terraform apply

Important Factoids

Raising this value with the timeouts metadata block to 2m solved this issue for me.
