availableMemoryMbinteger (int32)

The amount of memory in MB available for a function. Defaults to 256MB.

buildEnvironmentVariablesobject

Build environment variables that shall be available during build time.

buildIdstring

Output only. The Cloud Build ID of the latest successful deployment of the function.

buildNamestring

Output only. The Cloud Build Name of the function deployment. `projects//locations//builds/`.

buildWorkerPoolstring

Name of the Cloud Build Custom Worker Pool that should be used to build the function. The format of this field is `projects/{project}/locations/{region}/workerPools/{workerPool}` where `{project}` and `{region}` are the project id and region respectively where the worker pool is defined and `{workerPool}` is the short name of the worker pool. If the project id is not the same as the function, then the Cloud Functions Service Agent (`service-@gcf-admin-robot.iam.gserviceaccount.com`) must be granted the role Cloud Build Custom Workers Builder (`roles/cloudbuild.customworkers.builder`) in the project.

descriptionstring

User-provided description of a function.

dockerRegistrystring

Docker Registry to use for this deployment. If `docker_repository` field is specified, this field will be automatically set as `ARTIFACT_REGISTRY`. If unspecified, it currently defaults to `CONTAINER_REGISTRY`. This field may be overridden by the backend for eligible deployments.

One ofDOCKER_REGISTRY_UNSPECIFIEDCONTAINER_REGISTRYARTIFACT_REGISTRY

dockerRepositorystring

User managed repository created in Artifact Registry optionally with a customer managed encryption key. If specified, deployments will use Artifact Registry. If unspecified and the deployment is eligible to use Artifact Registry, GCF will create and use a repository named 'gcf-artifacts' for every deployed region. This is the repository to which the function docker image will be pushed after it is built by Cloud Build. It must match the pattern `projects/{project}/locations/{location}/repositories/{repository}`. Cross-project repositories are not supported. Cross-location repositories are not supported. Repository format must be 'DOCKER'.

entryPointstring

The name of the function (as defined in source code) that will be executed. Defaults to the resource name suffix, if not specified. For backward compatibility, if function with given name is not found, then the system will try to use function named "function". For Node.js this is name of a function exported by the module specified in `source_location`.

environmentVariablesobject

Environment variables that shall be available during function execution.

eventTriggerobject

Describes EventTrigger, used to request events be sent from another service.

eventTypestring

Required. The type of event to observe. For example: `providers/cloud.storage/eventTypes/object.change` and `providers/cloud.pubsub/eventTypes/topic.publish`. Event types match pattern `providers/*/eventTypes/*.*`. The pattern contains: 1. namespace: For example, `cloud.storage` and `google.firebase.analytics`. 2. resource type: The type of resource on which event occurs. For example, the Google Cloud Storage API includes the type `object`. 3. action: The action that generates the event. For example, action for a Google Cloud Storage Object is 'change'. These parts are lower case.

failurePolicyobject1 fields

Describes the policy in case of function's execution failure. If empty, then defaults to ignoring failures (i.e. not retrying them).

resourcestring

Required. The resource(s) from which to observe events, for example, `projects/_/buckets/myBucket`. Not all syntactically correct values are accepted by all services. For example: 1. The authorization model must support it. Google Cloud Functions only allows EventTriggers to be deployed that observe resources in the same project as the `CloudFunction`. 2. The resource type must match the pattern expected for an `event_type`. For example, an `EventTrigger` that has an `event_type` of "google.pubsub.topic.publish" should have a resource that matches Google Cloud Pub/Sub topics. Additionally, some services may support short names when creating an `EventTrigger`. These will always be returned in the normalized "long" format. See each *service's* documentation for supported formats.

servicestring

The hostname of the service that should be observed. If no string is provided, the default service implementing the API will be used. For example, `storage.googleapis.com` is the default for all event types in the `google.storage` namespace.

httpsTriggerobject

Describes HttpsTrigger, could be used to connect web hooks to function.

securityLevelstring

The security level for the function.

One ofSECURITY_LEVEL_UNSPECIFIEDSECURE_ALWAYSSECURE_OPTIONAL

urlstring

Output only. The deployed url for the function.

ingressSettingsstring

The ingress settings for the function, controlling what traffic can reach it.

One ofINGRESS_SETTINGS_UNSPECIFIEDALLOW_ALLALLOW_INTERNAL_ONLYALLOW_INTERNAL_AND_GCLB

kmsKeyNamestring

Resource name of a KMS crypto key (managed by the user) used to encrypt/decrypt function resources. It must match the pattern `projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}`. If specified, you must also provide an artifact registry repository using the `docker_repository` field that was created with the same KMS crypto key. The following service accounts need to be granted the role 'Cloud KMS CryptoKey Encrypter/Decrypter (roles/cloudkms.cryptoKeyEncrypterDecrypter)' on the Key/KeyRing/Project/Organization (least access preferred). 1. Google Cloud Functions service account (service-{project_number}@gcf-admin-robot.iam.gserviceaccount.com) - Required to protect the function's image. 2. Google Storage service account (service-{project_number}@gs-project-accounts.iam.gserviceaccount.com) - Required to protect the function's source code. If this service account does not exist, deploying a function without a KMS key or retrieving the service agent name provisions it. For more information, see https://cloud.google.com/storage/docs/projects#service-agents and https://cloud.google.com/storage/docs/getting-service-agent#gsutil. Google Cloud Functions delegates access to service agents to protect function resources in internal projects that are not accessible by the end user.

labelsobject

Labels associated with this Cloud Function.

maxInstancesinteger (int32)

The limit on the maximum number of function instances that may coexist at a given time. In some cases, such as rapid traffic surges, Cloud Functions may, for a short period of time, create more instances than the specified max instances limit. If your function cannot tolerate this temporary behavior, you may want to factor in a safety margin and set a lower max instances value than your function can tolerate. See the [Max Instances](https://cloud.google.com/functions/docs/max-instances) Guide for more details.

minInstancesinteger (int32)

A lower bound for the number function instances that may coexist at a given time.

namestring

A user-defined name of the function. Function names must be unique globally and match pattern `projects/*/locations/*/functions/*`

networkstring

The VPC Network that this cloud function can connect to. It can be either the fully-qualified URI, or the short name of the network resource. If the short network name is used, the network must belong to the same project. Otherwise, it must belong to a project within the same organization. The format of this field is either `projects/{project}/global/networks/{network}` or `{network}`, where `{project}` is a project id where the network is defined, and `{network}` is the short name of the network. This field is mutually exclusive with `vpc_connector` and will be replaced by it. See [the VPC documentation](https://cloud.google.com/compute/docs/vpc) for more information on connecting Cloud projects.

runtimestring

Response

Returns 200 with an object. Read it in later steps with {{cloudfunctionsProjectsLocationsFunctionsCreate.response.data.<field>}}.

doneboolean

If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.

errorobject

The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors).

codeinteger (int32)

The status code, which should be an enum value of google.rpc.Code.

detailsarray<object>

A list of messages that carry the error details. There is a common set of message types for APIs to use.

messagestring

A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.

metadataobject

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

namestring

The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the `name` should be a resource name ending with `operations/{unique_id}`.

responseobject

The normal response of the operation in case of success. If the original method returns no data on success, such as `Delete`, the response is `google.protobuf.Empty`. If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`.
