Args:
body: object, The request body.
The object takes the form of:
{ # The pipeline object. Represents a transformation from a set of input parameters to a set of output parameters. The transformation is defined as a docker image and command to run within that image. Each pipeline is run on a Google Compute Engine VM. A pipeline can be created with the `create` method and then later run with the `run` method, or a pipeline can be defined and run all at once with the `run` method.
"description": "A String", # User-specified description.
"docker": { # The Docker execuctor specification. # Specifies the docker run information.
"cmd": "A String", # Required. The command or newline delimited script to run. The command string will be executed within a bash shell. If the command exits with a non-zero exit code, output parameter de-localization will be skipped and the pipeline operation's `error` field will be populated. Maximum command string length is 16384.
"imageName": "A String", # Required. Image name from either Docker Hub or Google Container Registry. Users that run pipelines must have READ access to the image.
},
"inputParameters": [ # Input parameters of the pipeline.
{ # Parameters facilitate setting and delivering data into the pipeline's execution environment. They are defined at create time, with optional defaults, and can be overridden at run time. If `localCopy` is unset, then the parameter specifies a string that is passed as-is into the pipeline, as the value of the environment variable with the given name. A default value can be optionally specified at create time. The default can be overridden at run time using the inputs map. If no default is given, a value must be supplied at runtime. If `localCopy` is defined, then the parameter specifies a data source or sink, both in Google Cloud Storage and on the Docker container where the pipeline computation is run. The service account associated with the Pipeline (by default the project's Compute Engine service account) must have access to the Google Cloud Storage paths. At run time, the Google Cloud Storage paths can be overridden if a default was provided at create time, or must be set otherwise. The pipeline runner should add a key/value pair to either the inputs or outputs map. The indicated data copies will be carried out before/after pipeline execution, just as if the corresponding arguments were provided to `gsutil cp`. For example: Given the following `PipelineParameter`, specified in the `inputParameters` list: ``` {name: "input_file", localCopy: {path: "file.txt", disk: "pd1"}} ``` where `disk` is defined in the `PipelineResources` object as: ``` {name: "pd1", mountPoint: "/mnt/disk/"} ``` We create a disk named `pd1`, mount it on the host VM, and map `/mnt/pd1` to `/mnt/disk` in the docker container. At runtime, an entry for `input_file` would be required in the inputs map, such as: ``` inputs["input_file"] = "gs://my-bucket/bar.txt" ``` This would generate the following gsutil call: ``` gsutil cp gs://my-bucket/bar.txt /mnt/pd1/file.txt ``` The file `/mnt/pd1/file.txt` maps to `/mnt/disk/file.txt` in the Docker container. Acceptable paths are: Google Cloud storage pathLocal path file file glob directory For outputs, the direction of the copy is reversed: ``` gsutil cp /mnt/disk/file.txt gs://my-bucket/bar.txt ``` Acceptable paths are: Local pathGoogle Cloud Storage path file file file directory - directory must already exist glob directory - directory will be created if it doesn't exist One restriction due to docker limitations, is that for outputs that are found on the boot disk, the local path cannot be a glob and must be a file.
"defaultValue": "A String", # The default value for this parameter. Can be overridden at runtime. If `localCopy` is present, then this must be a Google Cloud Storage path beginning with `gs://`.
"description": "A String", # Human-readable description.
"localCopy": { # LocalCopy defines how a remote file should be copied to and from the VM. # If present, this parameter is marked for copying to and from the VM. `LocalCopy` indicates where on the VM the file should be. The value given to this parameter (either at runtime or using `defaultValue`) must be the remote path where the file should be.
"disk": "A String", # Required. The name of the disk where this parameter is located. Can be the name of one of the disks specified in the Resources field, or "boot", which represents the Docker instance's boot disk and has a mount point of `/`.
"path": "A String", # Required. The path within the user's docker container where this input should be localized to and from, relative to the specified disk's mount point. For example: file.txt,
},
"name": "A String", # Required. Name of the parameter - the pipeline runner uses this string as the key to the input and output maps in RunPipeline.
},
],
"name": "A String", # Required. A user specified pipeline name that does not have to be unique. This name can be used for filtering Pipelines in ListPipelines.
"outputParameters": [ # Output parameters of the pipeline.
{ # Parameters facilitate setting and delivering data into the pipeline's execution environment. They are defined at create time, with optional defaults, and can be overridden at run time.

},
],
"pipelineId": "A String", # Unique pipeline id that is generated by the service when CreatePipeline is called. Cannot be specified in the Pipeline used in the CreatePipelineRequest, and will be populated in the response to CreatePipeline and all subsequent Get and List calls. Indicates that the service has registered this pipeline.
"projectId": "A String", # Required. The project in which to create the pipeline. The caller must have WRITE access.
"resources": { # The system resources for the pipeline run. # Required. Specifies resource requirements for the pipeline run. Required fields: * minimumCpuCores * minimumRamGb
"acceleratorCount": "A String", # Optional. The number of accelerators of the specified type to attach. By specifying this parameter, you will download and install the following third-party software onto your managed Compute Engine instances: NVIDIA® Tesla® drivers and NVIDIA® CUDA toolkit.
"acceleratorType": "A String", # Optional. The Compute Engine defined accelerator type. By specifying this parameter, you will download and install the following third-party software onto your managed Compute Engine instances: NVIDIA® Tesla® drivers and NVIDIA® CUDA toolkit. Please see https://cloud.google.com/compute/docs/gpus/ for a list of available accelerator types.
"bootDiskSizeGb": 42, # The size of the boot disk. Defaults to 10 (GB).
"disks": [ # Disks to attach.
{ # A Google Compute Engine disk resource specification.
"autoDelete": True or False, # Deprecated. Disks created by the Pipelines API will be deleted at the end of the pipeline run, regardless of what this field is set to.
"mountPoint": "A String", # Required at create time and cannot be overridden at run time. Specifies the path in the docker container where files on this disk should be located. For example, if `mountPoint` is `/mnt/disk`, and the parameter has `localPath` `inputs/file.txt`, the docker container can access the data at `/mnt/disk/inputs/file.txt`.
"name": "A String", # Required. The name of the disk that can be used in the pipeline parameters. Must be 1 - 63 characters. The name "boot" is reserved for system use.
"readOnly": True or False, # Specifies how a sourced-base persistent disk will be mounted. See https://cloud.google.com/compute/docs/disks/persistent-disks#use_multi_instances for more details. Can only be set at create time.
"sizeGb": 42, # The size of the disk. Defaults to 500 (GB). This field is not applicable for local SSD.
"source": "A String", # The full or partial URL of the persistent disk to attach. See https://cloud.google.com/compute/docs/reference/latest/instances#resource and https://cloud.google.com/compute/docs/disks/persistent-disks#snapshots for more details.
"type": "A String", # Required. The type of the disk to create.
},
],
"minimumCpuCores": 42, # The minimum number of cores to use. Defaults to 1.
"minimumRamGb": 3.14, # The minimum amount of RAM to use. Defaults to 3.75 (GB)
"noAddress": True or False, # Whether to assign an external IP to the instance. This is an experimental feature that may go away. Defaults to false. Corresponds to `--no_address` flag for [gcloud compute instances create] (https://cloud.google.com/sdk/gcloud/reference/compute/instances/create). In order to use this, must be true for both create time and run time. Cannot be true at run time if false at create time.

{ # The pipeline object. Represents a transformation from a set of input parameters to a set of output parameters. The transformation is defined as a docker image and command to run within that image. Each pipeline is run on a Google Compute Engine VM. A pipeline can be created with the `create` method and then later run with the `run` method, or a pipeline can be defined and run all at once with the `run` method.
"description": "A String", # User-specified description.
"docker": { # The Docker execuctor specification. # Specifies the docker run information.
"cmd": "A String", # Required. The command or newline delimited script to run. The command string will be executed within a bash shell.

A default value can be optionally specified at create time. The default can be overridden at run time using the inputs map. If no default is given, a value must be supplied at runtime. If `localCopy` is defined, then the parameter specifies a data source or sink, both in Google Cloud Storage and on the Docker container where the pipeline computation is run.

"done": True or False, # 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.
"error": { # 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). # The error result of the operation in case of failure or cancellation.
"code": 42, # The status code, which should be an enum value of google.rpc.Code.
"details": [ # A list of messages that carry the error details. There is a common set of message types for APIs to use.
{
"a_key": "", # Properties of the object. Contains field @type with type URL.
},
],
"message": "A String", # 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.
},
"metadata": { # An OperationMetadata or Metadata object. This will always be returned with the Operation.
"a_key": "", # Properties of the object. Contains field @type with type URL.
},
"name": "A String", # The server-assigned name, which is only unique within the same service that originally returns it. For example: `operations/CJHU7Oi_ChDrveSpBRjfuL-qzoWAgEw`
"response": { # An Empty object.
"a_key": "", # Properties of the object. Contains field @type with type URL.
},

<div class="method">
<code class="details" id="setOperationStatus">setOperationStatus(body=None, x__xgafv=None)</code>
<pre>Sets status of a given operation. Any new timestamps (as determined by description) are appended to TimestampEvents. Should only be called by VMs created by the Pipelines Service and not by end users.
Args:
body: object, The request body.
The object takes the form of:
{ # Request to set operation status. Should only be used by VMs created by the Pipelines Service and not by end users.
"errorCode": "A String",
"errorMessage": "A String",
"operationId": "A String",
"timestampEvents": [
{ # Stores the list of events and times they occured for major events in job execution.
"description": "A String", # String indicating the type of event
"timestamp": "A String", # The time this event occured.
},
],
"validationToken": "A String",
}
x__xgafv: string, V1 error format.
Allowed values
1 - v1 error format
2 - v2 error format
Returns:
An object of the form:
{ # A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); } The JSON representation for `Empty` is empty JSON object `{}`.
