I want to override the value of root_volume_type to gp2 in https://github.com/terraform-aws-modules/terraform-aws-eks/blob/master/local.tf
This is the only file I created called main.tf in my terraform code. I want to override this in the code and not set it via the command line while running terraform apply
module "eks_example_basic" {
source = "terraform-aws-modules/eks/aws//examples/basic"
version = "14.0.0"
region = "us-east-1"
}
The error is correct because you are sourcing an example, which does not support such variables as workers_group_defaults. You can't overwrite it, unless you fork the example and modify it yourself.
workers_group_defaults is supported in the core module, for instance:
data "aws_vpc" "default" {
default = true
}
data "aws_subnet_ids" "default" {
vpc_id = data.aws_vpc.default.id
}
module "eks_example" {
source = "terraform-aws-modules/eks/aws"
version = "14.0.0"
cluster_name = "SomeEKSCluster"
cluster_version = "1.18"
subnets = data.aws_subnet_ids.default.ids
vpc_id = data.aws_vpc.default.id
workers_group_defaults = { root_volume_type = "gp2" }
}

I've an issue with terraform that i really don't understand.
Let me explain :
When i run
terraform init all good
terraform fmt all good
terraform validate all good
However when i run terraform plan i get an ERROR
terraform plan
I set the AWS_ACCESS_KEY & AWS_SECRET_key on the code to test it faster ( otherwise the value are passed by gitlab )
If i try without them on the variable.tf and use the value i export before to use AWS CLI everything work perfecty and i can deploy on aws .
variable.tf
variable "aws_region" {
default = "eu-central-1"
}
variable "bucket_name" {
type = string
default = "test-bucket"
}
variable "aws_access_key" {
default = "XXXXXXXXXXXXXXXXX"
}
variable "aws_secret_key" {
default = "XXXXXXXXXXXXXX"
}
main.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 4.9.0"
}
}
}
provider "aws" {
region = var.aws_region
access_key = var.aws_access_key
secret_key = var.aws_secret_key
# Make faster by skipping something

Thanks for your help guy .
I don't know what to do anymore
Try using
"region"
"access_key"
"secret_key"
without
aws_
as the prefix to your variable.tf and main.tf
Sometimes it creates conflict with terraform code.
It looks like the cause is aws_ prefix. When it is used in a variable names this error occurs.
I want to use the first module output value in another module
current scenario -
modules
--network
--main.tf
--output.tf
--variable.tf
--server
--main.tf
--output.tf
--variable.tf
node.tf
I created VPC in the network modules
resource "google_compute_network" "default" {
name = var.vpc_name
}
resource "google_compute_subnetwork" "default" {
name = "my-subnet"
ip_cidr_range = "10.0.0.0/16"
region = "us-central1"
network = google_compute_network.default.id
}
and also output in the same directory /modules/network = cat output.tf
output "subnet_id" {
value = google_compute_subnetwork.id
}
and now I have another module called a server and there I want to use subnetwork that is my subnet id
cat /modules/server/main.tf
resource "google_compute_address" "internal_ip" {
name = "my-internal-address"
project = "fivenodeautomation"
subnetwork = ******* #google_compute_subnetwork.default.id
address_type = "INTERNAL"
address = "10.0.1.0"
region = "us-central1"
purpose = "GCE_ENDPOINT"
}
resource "google_compute_address" "static" {
name = "vm-public-address"
project = "fivenodeautomation"
region = "us-central1"
}
how do I access this subnetwork value in server modules
Thanks
I have multiple output variable, I want to make one parent out variable and then put other outputs into it. I have searched about it and found that we can user terraform object for it but can't get the syntax right.
Output.tf
output "public_subnet" {
value = "${module.my_vpc.public_subnets_ids}"
}
output "vpc_id" {
value = "${module.my_vpc.vpc_id}"
}
output "private_subnet" {
value = "${module.my_vpc.private_subnets_ids}"
}
I want my output to be in a object or you can say parent output variable that have all child output vales, I have come up with few line which I know is not right syntax wise but will get you a picture of what I am thinking of.
output "vpc" {
value = {
vpc_id = "${module.my_vpc.vpc_id}"
public_subnet = "${module.my_vpc.public_subnets_ids}"
private_subnet = "${module.my_vpc.private_subnets_ids}"
}
type = object({ vpc_id = string, public_subnet = string, private_subnet = string })
}
Terraform output does not have type. Therefore, your vpc should be:
output "vpc" {
value = {
vpc_id = "${module.my_vpc.vpc_id}"
public_subnet = "${module.my_vpc.public_subnets_ids}"
private_subnet = "${module.my_vpc.private_subnets_ids}"
}
}
But the issue is that a child module has no access to its parrent's outputs. Thus, I'm not exactly sure what do you want to achieve with your outputs. Normally, you would pass variables from parent to child using variable, and then you could make new output from those variables in the child module.
Update
Based on your previous questions, there is main.tf with
module "my_vpc" {
source = "./modules/vpc"
vpc_cidr = var.vpc_cidr
public_subnet = var.public_subnet
private_subnet = var.private_subnet
availability_zone = data.aws_availability_zones.azs.names
}
Therefore, you must have a folder ./modules/vpc. In the folder, there may be a file called ./modules/vpc/vpc.tf. The file will have something like this in it (variables could be in separate file as well):
variable "vpc_cidr" {}
variable "public_subnet" {}
variable "private_subnet" {}
variable "availability_zone" {}
# the rest of the VPC definition. Since the file is not given,
# i can only speculate on the exact details of the content
resource "aws_subnet" "public" {
count = length(var.public_subnet)
vpc_id = aws_vpc.my_vpc.id
# other attributes
}
resource "aws_subnet" "private" {
count = length(var.private_subnet)
vpc_id = aws_vpc.my_vpc.id
# other attributes
}
If so, then you can create a new file, called ./modules/vpc/output.tf with the content:
output "vpc" {
value = {
vpc_id = my_vpc.vpc_id
public_subnet = aws_subnet.public.*.id
private_subnet = aws_subnet.private.*.id
}
}
I'm trying to work with aws_instance data source. I created a simple configuration which should create an ec2 instance and should return ip as output
variable "default_port" {
type = string
default = 8080
}
provider "aws" {
region = "us-west-2"
shared_credentials_file = "/Users/kharandziuk/.aws/creds"
profile = "prototyper"
}
resource "aws_instance" "example" {
ami = "ami-0994c095691a46fb5"
instance_type = "t2.small"
tags = {
name = "example"
}
}
data "aws_instances" "test" {
instance_tags = {
name = "example"
}
instance_state_names = ["pending", "running", "shutting-down", "terminated", "stopping", "stopped"]
}
output "ip" {
value = data.aws_instances.test.public_ips
}
but for some reasons I can't configure data source properly. The result is:
> terraform plan
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.
data.aws_instances.test: Refreshing state...
Error: Your query returned no results. Please change your search criteria and try again.
on main.tf line 21, in data "aws_instances" "test":
21: data "aws_instances" "test" {
how can I fix it?
You should use depends_on option into data.aws_instances.test.
like :
data "aws_instances" "test" {
instance_tags = {
name = "example"
}
instance_state_names = ["pending", "running", "shutting-down", "terminated", "stopping", "stopped"]
depends_on = [
"aws_instance.example"
]
}
It means that build data.aws_instances.test after make resource.aws_instance.example.
Sometimes, We need to use this option. Because of dependencies of aws resources.
See :
Here's a document about depends_on option.
You don't need a data source here. You can get the public IP address of the instance back from the resource itself, simplifying everything.
This should do the exact same thing:
resource "aws_instance" "example" {
ami = "ami-0994c095691a46fb5"
instance_type = "t2.small"
tags = {
name = "example"
}
}
output "ip" {
value = aws_instance.example.public_ip
}
I am using Terraform v0.12.6. I am using modules to create a VPC,Subnets and EC2 instances.
root.tf
vpc.tf
pub_subnet.tf
web_server.tf
vpc.tf and pub_subnet.tf are working fine and displaying the required output. However, I am unable to use the subnet_id from the module pub_subnet.tf as input to my web_server.tf.
The reason being that it is a list and I am getting Inappropriate value for attribute "subnet_id": string required.
Looks like I have to read the terraform.tfstate file.
Here is my present code -
root.tf
provider "aws" {
region = "us-east-1"
}
data "terraform_remote_state" "public_subnet" {
backend = "local"
config = {
path = "terraform.tfstate"
}
}
module "my_vpc" {
source = "../modules/vpc_flowlogs"
vpc_cidr = "10.0.0.0/16"
# vpc_id = "${module.my_vpc.vpc_id}"
}
module "vpc_igw" {
source = "../modules/vpc_igw"
vpc_id = "${module.my_vpc.vpc_id}"
}
module "public_subnets" {
source="../modules/pub_subnets"
vpc_id = "${module.my_vpc.vpc_id}"
}
module "web_servers" {
source = "../modules/webservers"
vpc_id = "${module.my_vpc.vpc_id}"
subnet_id =
"${data.terraform_remote_state.public_subnet.outputs.subnet_id[0]}"
}
web_servers.tf
resource "aws_instance" "web-srvs" {
count="${var.instance_count == "0" ? "1" : var.instance_count}"
ami = "ami-035b3c7efe6d061d5"
instance_type = "t2.nano"
key_name="xxx-dev"
subnet_id = "${var.subnet_id}"
vpc_security_group_ids = ["${aws_security_group.pub_sg.id}"]
associate_public_ip_address=true
}
I am trying to use of the two subnet_ids created.
I have tried different ways but now running out of ideas.
Just as an FYI, my tfstate file is located in the same directory as root.tf
Appreciate any help. OR is this a bug ?
You're requesting a remote state for no reason. Remote state is for referencing output from other configs. You have modules so you should just change it to reference the module resource, but you are going to have to output the values in the module so you can reference it elsewhere.
subnet_id =
"${data.terraform_remote_state.public_subnet.outputs.subnet_id[0]}"
}
Should be
subnet_id =
"${module.public_subnets.subnet.id}"
}
In your subnet module, create an output resource.
output "subnet" {
value = "${aws_subnet.some_subnet.id}"
}
