Terraform a POC of a two region, 4 environment, Cloud Run App

Terraform multi-region multi-environment POC

Example Terraform code to build a simple Cloud Run service that lives in the GCP us-west1 region and the us-west4 region.

With one Terraform file per region, each file builds that regions Cloud Run service.

The environments are then set by flagging the vars file:

• dev
• test
• stage
• production

CLI for each environment

Development environment

terraform plan -var-file="dev-env.tfvars

Test environment

terraform plan -var-file="test-env.tfvars

Stage environment

terraform plan -var-file="stage-env.tfvars

Production environment

terraform plan -var-file="production-env.tfvars

Terraform variable file documentation

Variable Definitions (.tfvars) Files

To set lots of variables, it is more convenient to specify their values in a variable definitions file (with a filename ending in either .tfvars or .tfvars.json) and then specify that file on the command line with -var-file:

terraform apply -var-file="testing.tfvars"

Terraform also automatically loads a number of variable definitions files if they are present:

Files named exactly terraform.tfvars or terraform.tfvars.json.
Any files with names ending in .auto.tfvars or .auto.tfvars.json.
