GCP Cloud Run manager terraform module

This module manages a Cloud Run-hosted container. It takes care of making sure the container is connected to a Cloud SQL instance and sets environment variables on the application.

Specify the project to deploy into on the command line. So, for example, to deploy to the project my-project:

$ terraform init
$ terraform apply -var project=my-project

In this example, terraform is configured to use default application credentials. For Google APIs and these credentials should correspond to a user with owner or editor access to the target project. You can use the gcloud command line tool to set your personal credentials as application default credentials. See the gcloud auth application-default command output for more information.

Custom domain mapping

Setting the dns_name will create a domain mapping for the webapp. Before setting this value you must have verified ownership of the domain with Google. Instructions on how to do this can be found in the DevOps division guidebook.

Monitoring and Alerting

If the variable alerting_email_address is set, the module adds basic uptime alerting via email for failing http polling. See variables.tf for how to configure alerting and monitoring.

Note that the project containing resources to be monitored must be in a Stackdriver monitoring workspace and this must be configured manually. At the time of writing there is no terraform support for this. This module will error when applying if this is not so.

Stackdriver distinguishes between workspaces and projects within those workspaces. Each workspace must have a host project and that project must be the default project of the google.stackdriver provider used by this module. The google.stackdriver must be configured with credentials allowing monitoring resources to be created in the host project.

If the workspace host project differs from the project which contains the resources to be monitored, you can use a provider alias:

provider "google" {
  project = "my-project"

  # ... some credentials for the *project* admin ...
}

provider "google" {
  project = "stackdriver-host-project"
  alias   = "host"

  # ... some credentials for the *product* admin ...
}

module "cloud_run_service" {
  # ... other parameters ...

  providers = {
    google.stackdriver = google.host
  }
}
