Change Infrastructure
Now that we have bucket created, let’s modify it. Here’s the demo/main.tf
again.
app/stacks/demo/main.tf
resource "random_pet" "this" {
length = 2
}
module "bucket" {
source = "../../modules/example"
name = "bucket-${random_pet.this.id}"
uniform_bucket_level_access = var.uniform_bucket_level_access
location = var.location
}
As you can see there’s a var.uniform_bucket_level_access
variable. One way to update the infrastructure is to change the variable in the variables.tf
file directly.
app/stacks/demo/variables.tf
variable "uniform_bucket_level_access" {
description = "uniform_bucket_level_access"
type = bool
default = false
}
variable "location" {
description = "location"
type = string
default = "US"
}
However, you can also use tfvars
files. Terraspace will automatically use config/stacks/demo/tfvars
files according the TS_ENV
value. The default value is TS_ENV=dev
. We’ll use tfvars files so we can use the same code for different environments.
Generate Starter Tfvars Files
Addtionally, Terraspace can generate starter tfvar files for us with the terraspace seed
command.
$ terraspace seed demo
Reading: .terraspace-cache/us-central1/dev/stacks/demo/variables.tf
create config/stacks/demo/tfvars/dev.tfvars
$
The produced file looks something like this:
config/stacks/demo/tfvars/dev.tfvars
# Optional variables:
# uniform_bucket_level_access = false
# location = "US"
Terraspace parses the demo/variables.tf
file to generate the tfvars/dev.tfvars
file. It detected that all the variables are optional. We’ll uncomment uniform_bucket_level_access and change it to uniform_bucket_level_access = true
.
config/stacks/demo/tfvars/dev.tfvars
# Optional variables:
uniform_bucket_level_access = true
# location = "US"
Next, we’ll update the infrastructure.
