How to: configure timeouts for vpc module on aws_default_route_table

[cdancy]

Our vpc module seems to intermittently throw the below:

CREATE_FAILED : "terraform apply -auto-approve -no-color -input=false plan.json" command failed with code 1
        	            	
Error: error waiting for Route in Route Table (rtb-0179f2b9c38f21dd0) with destination (0.0.0.0/0) to become available: timeout while waiting for state to become 'ready' (timeout: 2m0s)

  with module.vpc.aws_route.private_nat_gateway[2],
  on .terraform/modules/vpc/main.tf line 1110, in resource "aws_route" "private_nat_gateway":
1110: resource "aws_route" "private_nat_gateway" {


Error: error reading Route Table Association (rtbassoc-00100b66ae8b7577e): Empty result

  with module.vpc.aws_route_table_association.public[0],
  on .terraform/modules/vpc/main.tf line 1204, in resource "aws_route_table_association" "public":
1204: resource "aws_route_table_association" "public" {

the default timeout of 2m is simply not enough for us and we'd like to increase it. Our vpc module is pretty basic and we don't attempt to do any additional configuration on the default route table (which is where I assume the above is coming from). I attempted to configure it like so:

resource "aws_default_route_table" "rtb-default" {
  default_route_table_id = module.vpc.default_vpc_main_route_table_id
  timeouts {
    create = "30m"
    update = "30m"
  }
}

But that then throws an exception saying:

1 validation error detected: Value '201-us-399200-rt-timeouts-2021110916415210_sgtnf-test-k8s-access-20211109165356' at 'functionName' failed to satisfy constraint: Member must have length less than or equal to 64

Not exactly sure how to move forward here. We just want to increase that default 2m timeout. Any suggestions?

Hi @cdancy

What version of this module are you using? The default route table time-out was updated in v3.9.0

[cdancy]

@msharma24 interesting ... I'm on version 3.6.0. I see it's bumped to 5m now. I'll try doing that. Still ... is there a sane way to configure this for future use-cases should that not be enough?

[msharma24]

I reckon updating the module version will fix your issue today. 5m time-out should not cause any more issues in the future too.

[cdancy]

@msharma24 fair enough and I'll give that a go. Thanks for the pointer.

@msharma24 so that worked, and things got farther, but now I'm hitting the below:

Error: error reading Route Table Association (rtbassoc-0b3f1e625ea7d6978): empty result

@cdancy Thanks for bringing that up!
Seeing the same error but not consistent.

Using version 3.10.0:

module.vpc.aws_route.private_nat_gateway[0]: Creation complete after 1s [id=r-rtb-0222974c8355a52aa1040279494]

╵

Any ideas or fix is much appreciated!
