Cloud Run Module
Cloud Run management, with support for IAM roles and Eventarc trigger creation.
Examples
IAM and environment variables
IAM bindings support the usual syntax. Container environment values can be declared as key-value strings or as references to Secret Manager secrets. Both can be combined as long as there is no duplication of keys:
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
name = "hello"
region = var.region
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
env = {
VAR1 = "VALUE1"
VAR2 = "VALUE2"
}
env_from_key = {
SECRET1 = {
secret = "credentials"
version = "1"
}
}
}
}
iam = {
"roles/run.invoker" = ["allUsers"]
}
}
# tftest modules=1 resources=2
Mounting secrets as volumes
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
name = "hello"
region = var.region
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
volume_mounts = {
"credentials" = "/credentials"
}
}
}
volumes = {
credentials = {
secret = {
name = "secret-manager-id"
path = "my-secret"
}
}
}
}
# tftest modules=1 resources=1
Beta features
To use beta features like Direct VPC Egress, set the launch stage to a preview stage.
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
name = "hello"
region = var.region
launch_stage = "BETA"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
revision = {
gen2_execution_environment = true
max_instance_count = 20
vpc_access = {
egress = "ALL_TRAFFIC"
subnet = "default"
tags = ["tag1", "tag2", "tag3"]
}
}
}
# tftest modules=1 resources=1
VPC Access Connector
You can use an existing VPC Access Connector to connect to a VPC from Cloud Run.
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
revision = {
vpc_access = {
connector = "connector-id"
egress = "ALL_TRAFFIC"
}
}
}
# tftest modules=1 resources=1
If creation of the VPC Access Connector is required, use the vpc_connector_create
variable which also supports optional attributes like number of instances, machine type, or throughput. The connector will be used automatically.
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
vpc_connector_create = {
ip_cidr_range = "10.10.10.0/24"
vpc_self_link = "projects/example/global/networks/vpc"
instances = {
max = 10
min = 2
}
}
}
# tftest modules=1 resources=2
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.
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
vpc_connector_create = {
machine_type = "e2-standard-4"
subnet = {
name = "subnet-name"
project_id = "host-project"
}
}
}
# tftest modules=1 resources=2
Eventarc triggers
PubSub
This deploys a Cloud Run service that will be triggered when messages are published to Pub/Sub topics.
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
eventarc_triggers = {
pubsub = {
topic-1 = "topic1"
topic-2 = "topic2"
}
}
}
# tftest modules=1 resources=3
Audit logs
This deploys a Cloud Run service that will be triggered when specific log events are written to Google Cloud audit logs.
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
eventarc_triggers = {
audit_log = {
setiampolicy = {
method = "SetIamPolicy"
service = "cloudresourcemanager.googleapis.com"
}
}
}
}
# tftest modules=1 resources=2
Using custom service accounts for triggers
By default Compute default service account
is used to trigger Cloud Run. If you want to use custom Service Accounts you can either provide your own in eventarc_triggers.service_account_email
or set eventarc_triggers.service_account_create
to true and service account named tf-cr-trigger-${var.name}
will be created with roles/run.invoker
granted on this Cloud Run service.
Example using provided service account:
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
eventarc_triggers = {
audit_log = {
setiampolicy = {
method = "SetIamPolicy"
service = "cloudresourcemanager.googleapis.com"
}
}
service_account_email = "cloud-run-trigger@my-project.iam.gserviceaccount.com"
}
}
# tftest modules=1 resources=2
Example using automatically created service account:
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
eventarc_triggers = {
pubsub = {
topic-1 = "topic1"
topic-2 = "topic2"
}
service_account_create = true
}
}
# tftest modules=1 resources=5
Cloud Run Service Account
To use a custom service account managed by the module, set service_account_create
to true
and leave service_account
set to null
(default).
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
service_account_create = true
}
# tftest modules=1 resources=2
To use an externally managed service account, use its email in service_account
and leave service_account_create
to false
(default).
module "cloud_run" {
source = "./fabric/modules/cloud-run-v2"
project_id = var.project_id
region = var.region
name = "hello"
containers = {
hello = {
image = "us-docker.pkg.dev/cloudrun/container/hello"
}
}
service_account = "cloud-run@my-project.iam.gserviceaccount.com"
}
