Import

Subscription can be imported using any of these accepted formats:

• projects/{{project}}/locations/{{zone}}/subscriptions/{{name}}
• {{project}}/{{zone}}/{{name}}
• {{zone}}/{{name}}
• {{name}}

When using the pulumi import command, Subscription can be imported using one of the formats above. For example:

$ pulumi import gcp:pubsub/liteSubscription:LiteSubscription default projects/{{project}}/locations/{{zone}}/subscriptions/{{name}}
$ pulumi import gcp:pubsub/liteSubscription:LiteSubscription default {{project}}/{{zone}}/{{name}}
$ pulumi import gcp:pubsub/liteSubscription:LiteSubscription default {{zone}}/{{name}}
$ pulumi import gcp:pubsub/liteSubscription:LiteSubscription default {{name}}

Constructors

LiteSubscription(String name, {LiteSubscriptionArgs? args, CustomResourceOptions? options})

Creates a new LiteSubscription. name The Pulumi resource name. args Arguments used to configure this LiteSubscription. The set of arguments for LiteSubscription. options Resource options controlling this resource's behavior.

LiteSubscription.reference(String urn)

Creates a typed reference to an existing LiteSubscription resource.

Properties

childResources → Set<Resource>

final, inherited

completionSources ↔ Map<String, IOutputCompletionSource>

late, final, inherited

deletionPolicy ↔ Output<String>

Whether Terraform will be prevented from destroying the resource. Defaults to DELETE. When a 'terraform destroy' or 'pulumi up' would delete the resource, the command will fail if this field is set to "PREVENT" in Terraform state. When set to "ABANDON", the command will remove the resource from Terraform management without updating or deleting the resource in the API. When set to "DELETE", deleting the resource is allowed.

late, final

deliveryConfig ↔ Output<LiteSubscriptionDeliveryConfig?>

The settings for this subscription's message delivery. Structure is documented below.

late, final

hashCode → int

The hash code for this object.

no setter, inherited

id ↔ Output<String>

getter/setter pair, inherited

isCustom → bool

Returns whether this resource is provider-managed.

no setter, inherited

isProtected → bool

Returns whether this resource is protected from deletion.

no setter, inherited

isRemote → bool

Whether this resource is registered as remote.

no setter, inherited

isResourceReference → bool

Whether this instance represents a resource value returned over RPC.

final, inherited

name ↔ Output<String>

Name of the subscription.

late, final

project ↔ Output<String>

The ID of the project in which the resource belongs. If it is not provided, the provider project is used.

late, final

region ↔ Output<String?>

The region of the pubsub lite topic.

late, final

resourceTransforms → List<ResourceTransform>

Inherited/explicit async transforms.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

topic ↔ Output<String>

A reference to a Topic resource.

late, final

transformations → List<ResourceTransformation>

Inherited/explicit legacy transformations.

no setter, inherited

urn ↔ Output<String>

late, final, inherited

zone ↔ Output<String?>

The zone of the pubsub lite topic.

late, final
