## Examples

### HTTP trigger

This deploys a Cloud Function with an HTTP endpoint, using a pre-existing GCS bucket for deployment, creating service account dedicated for this function, granting it `roles/logging.logWriter` and `roles/monitoring.metricWriter` roles, and delegating access control to the containing project.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest fixtures=fixtures/functions-default-sa-iam-grants.tf inventory=http-trigger.yaml e2e
```

### PubSub and non-HTTP triggers

Other trigger types other than HTTP are configured via the `trigger_config` variable. This example shows a PubSub trigger.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  trigger_config = {
    event    = "google.pubsub.topic.publish"
    resource = module.pubsub.topic.name
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]

}
# tftest inventory=pubsub-non-http-trigger.yaml fixtures=fixtures/pubsub.tf,fixtures/functions-default-sa-iam-grants.tf e2e
```

### Controlling HTTP access

To allow anonymous access to the function, grant the `roles/cloudfunctions.invoker` role to the special `allUsers` identifier. Use specific identities (service accounts, groups, etc.) instead of `allUsers` to only allow selective access.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  iam = {
    "roles/cloudfunctions.invoker" = ["allUsers"]
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest fixtures=fixtures/functions-default-sa-iam-grants.tf inventory=iam.yaml e2e
```

### GCS bucket creation

You can have the module auto-create the GCS bucket used for deployment via the `bucket_config` variable. Setting `bucket_config.location` to `null` will also use the function region for GCS.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  prefix      = var.prefix
  name        = "test-cf-http"
  bucket_name = var.bucket
  bucket_config = {
    force_destroy             = true
    lifecycle_delete_age_days = 1
  }
  bundle_config = {
    path = "assets/sample-function/"
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest fixtures=fixtures/functions-default-sa-iam-grants.tf inventory=bucket-creation.yaml e2e
```

### Service account management

To use a custom service account managed by the module, set `service_account_config.create` to `true`.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  service_account_config = {
    create = true
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest inventory=service-account.yaml fixtures=fixtures/functions-default-sa-iam-grants.tf e2e
```

To use an externally managed service account, pass its email in `service_account_config.email` and set `service_account_config.create` to `false`.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  service_account_config = {
    create = false
    email  = var.service_account.email
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest modules=1 resources=5 fixtures=fixtures/functions-default-sa-iam-grants.tf e2e
```

### Custom bundle config

The Cloud Function bundle can be configured via the `bundle_config` variable. The only mandatory argument is `bundle_config.path` which can point to:

- a GCS URI of a ZIP archive
- a local path to a ZIP archive
- a local path to a source folder

When a GCS URI or a local zip file are used, a change in their names will trigger redeployment. When a local source folder is used a ZIP archive will be automatically generated and its internally derived checksum will drive redeployment. You can optionally control its name and exclusions via the attributes in `bundle_config.folder_options`.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
    folder_options = {
      archive_path = "bundle.zip"
      excludes     = ["__pycache__"]
    }
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest inventory=custom-bundle.yaml fixtures=fixtures/functions-default-sa-iam-grants.tf  e2e
```

### Private Cloud Build Pool

This deploys a Cloud Function with an HTTP endpoint, using a pre-existing GCS bucket for deployment using a pre existing private Cloud Build worker pool.

```hcl
module "cf-http" {
  source            = "./fabric/modules/cloud-function-v1"
  project_id        = var.project_id
  region            = var.regions.secondary
  name              = "test-cf-http"
  bucket_name       = var.bucket
  build_worker_pool = google_cloudbuild_worker_pool.pool.id
  bundle_config = {
    path = "assets/sample-function/"
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest inventory=private-build-pool.yaml fixtures=fixtures/cloudbuild-custom-pool.tf,fixtures/functions-default-sa-iam-grants.tf e2e
```

### Multiple Cloud Functions within project

When deploying multiple functions do not reuse `bundle_config.archive_path` between instances as the result is undefined. Default `archive_path` creates file in `/tmp` folder using project Id and function name to avoid name conflicts.

```hcl
module "cf-http-one" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http-one"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
}

module "cf-http-two" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http-two"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}
# tftest fixtures=fixtures/functions-default-sa-iam-grants.tf inventory=multiple_functions.yaml e2e
```

### Mounting secrets from Secret Manager

This provides the latest value of the secret `var_secret` as `VARIABLE_SECRET` environment variable and three values of `path_secret` mounted in filesystem:

- `/app/secret/ver1` contains version referenced by `module.secret-manager.version_versions["credentials:v1"]`

Remember to grant access to secrets to the service account running Cloud Function.

```hcl
module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  secrets = {
    VARIABLE_SECRET = {
      is_volume  = false
      project_id = var.project_number # use project_number  to avoid perm-diff
      secret     = reverse(split("/", module.secret-manager.secrets["credentials"].name))[0]
      versions = [
        "latest"
      ]
    }
    "/app/secret" = {
      is_volume  = true
      project_id = var.project_number # use project_number  to avoid perm-diff
      secret     = reverse(split("/", module.secret-manager.secrets["credentials"].name))[0]
      versions = [
        "${module.secret-manager.version_versions["credentials/v1"]}:/ver1"
      ]
    }
  }
  depends_on = [
    google_project_iam_member.bucket_default_compute_account_grant,
  ]
}

module "secret-manager" {
  source     = "./fabric/modules/secret-manager"
  project_id = var.project_id
  secrets = {
    credentials = {
      iam = {
        "roles/secretmanager.secretAccessor" = [module.cf-http.service_account_iam_email]
      }
      versions = {
        v1 = { data = "manual foo bar spam" }
      }
    }
  }
}
# tftest fixtures=fixtures/functions-default-sa-iam-grants.tf inventory=secrets.yaml e2e skip-tofu
```

### Using CMEK to encrypt function resources

This encrypt bucket _gcf-sources-*_ with the provided kms key. The repository has to be encrypted with the same kms key.

```hcl
module "project" {
  source          = "./fabric/modules/project"
  name            = "cf-v1"
  billing_account = var.billing_account_id
  prefix          = var.prefix
  parent          = var.folder_id
  services = [
    "artifactregistry.googleapis.com",
    "cloudbuild.googleapis.com",
    "cloudfunctions.googleapis.com",
    "cloudkms.googleapis.com",
    "compute.googleapis.com",
    "storage.googleapis.com",
  ]
  iam = {
    # grant compute default service account that is used by Cloud Founction
    # permission to read from the buckets so it can read function sources
    "roles/storage.objectViewer" = [
      "serviceAccount:${module.project.default_service_accounts.compute}"
    ]
  }
}

module "kms" {
  source     = "./fabric/modules/kms"
  project_id = module.project.project_id
  keyring = {
    location = var.regions.secondary
    name     = "${var.prefix}-keyring"
  }
  keys = {
    "key-regional" = {
    }
  }
  iam = {
    "roles/cloudkms.cryptoKeyEncrypterDecrypter" = [
      module.project.service_agents["artifactregistry"].iam_email,
      module.project.service_agents["cloudfunctions"].iam_email,
      module.project.service_agents["storage"].iam_email,
    ]
  }
}

module "artifact-registry" {
  source         = "./fabric/modules/artifact-registry"
  project_id     = module.project.project_id
  location       = var.regions.secondary
  name           = "registry"
  format         = { docker = { standard = {} } }
  encryption_key = module.kms.key_ids["key-regional"]
  iam = {
    "roles/artifactregistry.createOnPushWriter" = [
      # grant compute default service account that is used by Cloud Build
      # permission to push compiled container into Artifact Registry
      "serviceAccount:${module.project.default_service_accounts.compute}",
    ]
  }
}

module "cf-http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = module.project.project_id
  region      = var.regions.secondary
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  kms_key = module.kms.key_ids["key-regional"]
  repository_settings = {
    repository = module.artifact-registry.id
  }
}
# tftest inventory=cmek.yaml
```

## VPC Access Connector

You can use an existing [VPC Access Connector](https://cloud.google.com/vpc/docs/serverless-vpc-access) to connect to a VPC from Cloud Run.

```hcl
module "cf_http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.region
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  vpc_connector = {
    name           = google_vpc_access_connector.connector.id
    egress_setting = "ALL_TRAFFIC"
  }
}
# tftest fixtures=fixtures/vpc-connector.tf inventory=service-vpc-access-connector.yaml
```

If creation of the VPC Access Connector is required, use the `vpc_connector.create` and `vpc_connector_create` variable which also supports optional attributes like number of instances, machine type, or throughput.

```hcl
module "cf_http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.region
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  vpc_connector = {
    create = true
  }
  vpc_connector_create = {
    ip_cidr_range = "10.10.10.0/28"
    network       = var.vpc.self_link
    instances = {
      max = 10
      min = 3
    }
  }
}
# tftest inventory=service-vpc-access-connector-create.yaml
```

Note that if you are using a Shared VPC for the connector, you need to specify a subnet and the host project if this is not where the Cloud Run service is deployed.

```hcl
module "cf_http" {
  source      = "./fabric/modules/cloud-function-v1"
  project_id  = var.project_id
  region      = var.region
  name        = "test-cf-http"
  bucket_name = var.bucket
  bundle_config = {
    path = "assets/sample-function/"
  }
  vpc_connector = {
    create = true
  }
  vpc_connector_create = {
    machine_type = "e2-standard-4"
    subnet = {
      name       = module.net-vpc-host.subnets["${var.region}/fixture-subnet-28"].name
      project_id = module.project-host.project_id
    }
    throughput = {
      max = 300
      min = 200
    }
  }
}
# tftest fixtures=fixtures/shared-vpc.tf inventory=service-vpc-access-connector-create-sharedvpc.yaml
```
