Project Setup

Variables

The following variables need to be set either by setting proper environment variables or editing the variables.tf file:

Variable	Type	Description
project_id	string	GCP ProjectID
cloudsql_db_name	string	Database name
cloudsql_username	string	Database primary username
cloudsql_password	string	Database primary user's password
cloudsql_tier	string	Instance tier to deploy your CloudSQL database to.
region	string	Region to deploy your CloudSQL database to.

Setting environment variables

With Terraform you can set / override any Terraform variables using the TF_VAR_ format. This works great for CI Pipelines, and it is the method we employ in this project's .circleci folder.

• Example setting the region variable :

  export TF_VAR_region="us-east1"

You can also set your variables in a file named .tfvars or .tfvars.json. You can specify your variables file using the command line:

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

Remote State

You can setup or remove the configration for a remote state manually by editing or removing the backend.cfg file.

You can alternatively configure the bucket and `prefix varariables from the commandline allowing for variable interpolation:

terraform init -backend-config="bucket=${STATE_BUCKET}" -backend-config="prefix=${STATE_PREFIX}"
