and supports additional features of the following modules:

mineiros-io/terraform-google-cloud-run-iam

Getting Started

Most common usage of the module:

module "terraform-google-cloud-run" {
  source = "github.com/mineiros-io/terraform-google-cloud-run?ref=v0.2.1"

  name     = "example-name"
  location = "us-central1"

  template = {
    spec = {
      containers = [
        {
          image = "gcr.io/cloudrun/hello:latest"
        }
      ]
    }
  }
}

Module Argument Reference

See variables.tf and examples/ for details and use-cases.

Main Resource Configuration

name: (Required string)

Name must be unique within a namespace, within a Cloud Run region. Is required when creating resources. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated.
location: (Required string)

The location of the cloud run instance. eg us-central1.
project: (Optional string)

The ID of the project in which the resource belongs. If it is not provided, the provider project is used.
autogenerate_revision_name: (Optional bool)

If set to true, the revision name (template.metadata.name) will be omitted and autogenerated by Cloud Run. This cannot be set to true while template.metadata.name is also set. (For legacy support, if template.metadata.name is unset in state while this field is set to false, the revision name will still autogenerate.).
template: (Optional object(template))

A template holds the latest specification for the Revision to be stamped out. The template references the container image, and may also include labels and annotations that should be attached to the Revision. To correlate a Revision, and/or to force a Revision to be created when the spec doesn't otherwise change, a nonce label may be provided in the template metadata.

Default is {}.

The template object accepts the following attributes:
- metadata: (Optional object(metadata))
  
  Optional metadata for this Revision, including labels and annotations. Name will be generated by the Configuration. To set minimum instances for this revision, use the autoscaling.knative.dev/minScale annotation key. To set maximum instances for this revision, use the autoscaling.knative.dev/maxScale annotation key. To set Cloud SQL connections for the revision, use the run.googleapis.com/cloudsql-instances annotation key.
  
  Default is {}.
  
  The metadata object accepts the following attributes:
  - name: (Optional string)
    
    Name must be unique within a namespace, within a Cloud Run region. Is required when creating resources. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/identifiers#names
  - namespace: (Optional string)
    
    In Cloud Run the namespace must be equal to either the project ID or project number. It will default to the resource's project.
  - labels: (Optional map(string))
    
    Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and routes. More info: http://kubernetes.io/docs/user-guide/labels
  - annotations: (Optional map(string))
    
    Annotations is a key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. More info: http://kubernetes.io/docs/user-guide/annotations Note: The Cloud Run API may add additional annotations that were not provided in your config. If terraform plan shows a diff where a server-side annotation is added, you can add it to your config or apply the lifecycle.ignore_changes rule to the metadata.0.annotations field.
- spec: (Required object(spec))
  
  RevisionSpec holds the desired state of the Revision (from the client).
  
  The spec object accepts the following attributes:
  - container_concurrency: (Optional number)
    
    ContainerConcurrency specifies the maximum allowed in-flight (concurrent) requests per container of the Revision. Values are:
    - 0 thread-safe, the system should manage the max concurrency. This is the default value.
    - 1 not-thread-safe. Single concurrency
    - 2-N thread-safe, max concurrency of N
  - timeout_seconds: (Optional number)
    
    TimeoutSeconds holds the max duration the instance is allowed for responding to a request.
  - service_account_name: (Optional string)
    
    Email address of the IAM service account associated with the revision of the service. The service account represents the identity of the running revision, and determines what permissions the revision has. If not provided, the revision will use the project's default service account.
  - containers: (Required list(container))
    
    Container defines the unit of execution for this Revision. In the context of a Revision, we disallow a number of the fields of this Container, including: name, ports, and volumeMounts. The runtime contract is documented here: https://github.com/knative/serving/blob/master/docs/runtime-contract.md
    
    Each container object in the list accepts the following attributes:
    - args: (Optional list(string))

Module Versioning

This Module follows the principles of Semantic Versioning (SemVer).

Given a version number MAJOR.MINOR.PATCH, we increment the:

MAJOR version when we make incompatible changes,
MINOR version when we add functionality in a backwards compatible manner, and
PATCH version when we make backwards compatible bug fixes.

Backwards compatibility in `0.0.z` and `0.y.z` version

Backwards compatibility in versions 0.0.z is not guaranteed when z is increased. (Initial development)
Backwards compatibility in versions 0.y.z is not guaranteed when y is increased. (Pre-release)
