heroku.formation.Formation

Explore with Pulumi AI

Provides a Heroku Formation resource.

A formation represents the formation of processes that should be set for an application.

Please note the following:

  • The application must have a dyno in order to update its formation.
  • If the heroku formation resource is removed and deleted, this will be a no-op action in Heroku. The Heroku Platform does not have a DELETE endpoint for formation.
  • This resource works well with the heroku.app.Release resource, which allows you to deploy a slug/release to an application before the formation can be updated.

Example Usage

# Creates a new application called foobar
resource "heroku_app" "foobar" {
    name = "foobar"
    region = "us"
}

# Creates a new release for application foobar using a slug id
resource "heroku_app_release" "foobar-release" {
    app_id = heroku_app.foobar.id
    slug_id = "01234567-89ab-cdef-0123-456789abcdef"
}

# Update the web formation for the foobar application's web
resource "heroku_formation" "foobar-web" {
    app_id = heroku_app.foobar.id
    type = "web"
    quantity = 2
    size = "standard-2x"

    # Tells Terraform that this formation must be created/updated only after the app release has been created
    depends_on = ["heroku_app_release.foobar-release"]
}

Create Formation Resource

Resources are created with functions called constructors. To learn more about declaring and configuring resources, see Resources.

Constructor syntax

new Formation(name: string, args: FormationArgs, opts?: CustomResourceOptions);
@overload
def Formation(resource_name: str,
              args: FormationArgs,
              opts: Optional[ResourceOptions] = None)
