The first error is the named validation problem.

Second Elb Module Terraform problem

[antonbabenko]

First assumption is that you have named your DB instance starting with the letter. Text labels are passed into module as argument (name_prefix) without validation (there is WIP issue already - #18).

ALB is failing because you have to specify "At least two subnets in two different Availability Zones must be specified". If you have edited this manually, make sure you set it correctly. Normally VPC resources like subnets are created across all available AZs.

If problem persists, please share a link to your blueprint by email.

[Genaker]

Yes, but we can't manage Az in the cloud craft. It is something that scripts (module.tf) do during the import. Name prefix is

  # The name of the RDS instance, if omitted, Terraform will assign a random, unique identifier
  # type: string
  identifier = "MySQL-Master-RDS"

name_prefix is not part of terragrunt configuration

[Genaker]

Hi! I still struggling with this error.

Error: first character of "name_prefix" must be a letter
  on modules/db_option_group/main.tf line 1, in resource "aws_db_option_group" "this":

And the weirdest one is ALB doesn't work

Error: Error creating application Load Balancer: ValidationError: At least two subnets in two different Availability Zones must be specified
	status code: 400, request id: 3cbf0f7c-24bc-4461-b9db-2a2a91886a49

I'm trying to fix parameter name by fix name

[antonbabenko]

RDS identifier is using wrong characters inside but since that value is used to create some other resources you need to update it to satisfy these error messages - "only lowercase alphanumeric characters and hyphens", "first character ... must be a letter".

ALB error is probably related to a missing subnets argument which should look like this:

inputs {
  # ... omitted
  subnets = dependency.vpc.outputs.public_subnets
}

If not, please show inputs in alb directory and I will try to help.

[Genaker]

Yes, there are no
subnets = dependency.vpc.outputs.public_subnets

###########################################################

}

[Genaker]

I have fixed RDS issue by removing "-" sign from the name.

but this error a little bit weird :

Error: Error creating application Load Balancer: ValidationError: At least two subnets in two different Availability Zones must be specified

    },

[antonbabenko]

Add subnets = dependency.vpc.outputs.public_subnets into alb.

It was not specified automatically, because your ALB was not belonging to a VPC in a diagram, I suppose.

[Genaker]

It is belonging to the VPC... it just doesn't generate it

Can you also provide how to add these values they are missing also .

I checked old version

security_groups = [] # @tfvars:terraform_output.security-group_5.this_security_group_id.to_list

  # A list of subnets to associate with the load balancer. e.g. ['subnet-1a2b3c4d','subnet-1a2b3c4e','subnet-1a2b3c4f']
  # type: list
  subnets = ["subnet-00703b43f38b8f971","subnet-00703b43f38b8f971","subnet-0c2dd15008a01bb51"] # @tfvars:terraform_output.vpc.public_subnets

  # VPC id where the load balancer and other resources will be deployed.
  # type: string
  vpc_id = "" # @tfvars:terraform_output.vpc.vpc_id

I have this dependencies:

dependencies {
paths = ["../vpc-cloud", "../loadbalancer-internet-securitygroup"]
}

  # Controls if the ALB will log requests to S3.
  # type: bool
  logging_enabled = false

  # The security groups to attach to the load balancer. e.g. ["sg-edcd9784","sg-edcd9785"]
  # type: list(string)
  security_groups = [dependency.security-group_5.outputs.this_security_group_id]

  # A list of subnets to associate with the load balancer. e.g. ['subnet-1a2b3c4d','subnet-1a2b3c4e','subnet-1a2b3c4f']
  # type: list(string)
  subnets = dependency.vpc.outputs.public_subnets

  # VPC id where the load balancer and other resources will be deployed.
  # type: string
  vpc_id = dependency.vpc.outputs.vpc_id

[Genaker]

it is an example - https://app.cloudcraft.co/view/f8abab63-0007-4ea2-8ea8-b9186d3259f1?key=iBtyR4AsIr9jWfy-sJARUg

it doesn't add a subnet to ELB

my blueprint is - blueprint/0b356102-1692-478a-a0fa-901c9323ab1f

[Genaker]

RDS name_prefix issue fixed after setting name to "mysql" without any symbols instead of "mysql-rds".

[antonbabenko]

A similar issue is when a security group is named ...-sg (and ...-vpc for VPC, if I remember correctly now).

Pretty weird requirements by AWS.

[Genaker]

After run "terragrunt apply-all" but load balancer doesn't have target groups/listeners created and so no instances are load-balanced
