Backend Config DSL
You can also optionally write your backend config in Ruby with config/terraform/backend.rb. With the DSL you do not have to use the expansion helper, Terraspace automatically runs it on each hash value. Below are some examples.
S3 Backend
config/terraform/backend.rb
backend("s3",
bucket: "terraform-state-:ACCOUNT-:REGION-:ENV",
key: ":PROJECT/:TYPE_DIR/:APP/:ROLE/:MOD_NAME/:ENV/:EXTRA/:REGION/terraform.tfstate",
region: ":REGION",
encrypt: true,
dynamodb_table: "terraform_locks"
)
Azure Backend
config/terraform/backend.rb
backend("azurerm",
resource_group_name: ":ENV-:LOCATION"
storage_account_name: "ts:APP_HASH:SUBSCRIPTION_HASH:LOCATION_HASH:ENV"
container_name: "terraform-state"
key: ":PROJECT/:TYPE_DIR/:APP/:ROLE/:MOD_NAME/:ENV/:EXTRA/:LOCATION/terraform.tfstate"
)
GCS Backend
Here’s an example for a gcs backend with Ruby.
config/terraform/backend.rb
backend("gcs",
bucket: "terraform-state-:PROJECT-:REGION-:ENV",
prefix: ":PROJECT/:TYPE_DIR/:APP/:ROLE/:MOD_NAME/:ENV/:EXTRA/:REGION" # variable notation gets expanded out by terraspace
)
