The parameter CacheSubnetGroupName must be provided and must not be blank.

[perryluopl]

I use the module, https://github.com/cloudposse/terraform-aws-elasticache-redis to provision elasticache redis. Below are the errors when I run terraform apply. I have no clue of these errors.

Terraform version: v0.13.5

have you try defining elasticache_subnet_group_name?

[Gowiem]

@perryluopl got your email. Please try out @jamengual's suggestion. If you can't get it to work through using that parameter then please join the SweetOps slack group and we'll help you triage there.

[perryluopl]

I added elasticache_subnet_group_name = var.elasticache_subnet_group_name. I still get the error. The error complains ParameterGroupName.

what version of aws provider are you running @perryluopl ?

[perryluopl]

Here is my code. The version >= 2.28.1. What version should I use? My terraform version is v0.13.5.

provider "aws" { version = ">= 2.28.1" region = var.region }

[jamengual]

You could try with 3.15.0 of the aws provider and see

provider "aws" { version = "3.15.0" region = var.region }

I got error,

[perryluopl]

I changed to, provider "aws" {

version = "3.15.0"

version = ">= 2.49" region = var.region } But, I still got, module.redis.aws_elasticache_parameter_group.default[0]: Creating...

Are you able to run the code at terraform-aws-elasticache-redis/examples/complete successfully?

[jamengual]

Every version we release runs terratest which create the infrastructure.

Have you ever deployed one successfully?

No, I have not successfully deployed one yet.

[perryluopl]

Can anyone run the code I posted to reproduce the error?

[jamengual]

@perryluopl this recent run of the example shows this is working as expected:

https://github.com/cloudposse/actions/runs/1376256420?check_suite_focus=true

I used another PR and run all tests

[jamengual]

Join the slack channel so other people that have run elasticache can help you identify what is wrong

[perryluopl]

Found the problem. The default values of namespace/environment/stage/name in context.tf are null. That causes the problem. Set these values solved the problem.

[hknoa1729]

Still the issue persist with latest release dated today with 0.45.0

[mshiriv]

Still the issue persist with latest release dated today with 0.50.0

[stolarczyk]

The issue persists in 0.52.0

[vkryzh]

Seems like you are forced to create :(

  context = {
    "additional_tag_map" : {},
    "attributes" : [],
    "delimiter" : null,
    "descriptor_formats" : {},
    "enabled" : true,
    "environment" : null,
    "id_length_limit" : null,
    "label_key_case" : null,
    "label_order" : [],
    "label_value_case" : null,
    "labels_as_tags" : ["unset"],
    "name" : "SOMETHING_HERE",
    "namespace" : null,
    "regex_replace_chars" : null,
    "stage" : null,
    "tags" : {},
    "tenant" : null
  }

[kmkouokam]

I think you should create a resource "aws_elasticache_subnet_group" subnet-group" {}, and add an entry subnet_group_name in your module "redis"

[guhus]

Same here, still happening with 0.53.0, context is forced to be used, a bit odd.
