Runs a pipeline. The returned Operation's metadata field will contain a google.genomics.v2alpha1.Metadata object describing the status of the pipeline execution. The [response] field will contain a google.genomics.v2alpha1.RunPipelineResponse object if the pipeline completes successfully. Note: Before you can use this method, the Genomics Service Agent must have access to your project. This is done automatically when the Cloud Genomics API is first enabled, but if you delete this permission, or if you enabled the Cloud Genomics API before the v2alpha1 API launch, you must disable and re-enable the API to grant the Genomics Service Agent the required permissions. Authorization requires the following Google IAM permission: * genomics.operations.create [1]: /genomics/gsa

* Accelerator object: Carries information about an accelerator that can be attached to a VM.
* count string: How many accelerators of this type to attach.
* type string: The accelerator type string (for example, "nvidia-tesla-k80"). Only NVIDIA GPU accelerators are currently supported. If an NVIDIA GPU is attached, the required runtime libraries will be made available to all containers under /usr/local/nvidia. The driver version to install must be specified using the NVIDIA driver version parameter on the virtual machine specification. Note that attaching a GPU increases the worker VM startup time by a few minutes.

$3

* Action object: Specifies a single action that runs a Docker container.
* commands array: If specified, overrides the CMD specified in the container. If the container also has an ENTRYPOINT the values are used as entrypoint arguments. Otherwise, they are used as a command and arguments to run inside the container.
* items string
* credentials Secret
* entrypoint string: If specified, overrides the ENTRYPOINT specified in the container.
* environment object: The environment to pass into the container. This environment is merged with values specified in the google.genomics.v2alpha1.Pipeline message, overwriting any duplicate values. In addition to the values passed here, a few other values are automatically injected into the environment. These cannot be hidden or overwritten. GOOGLE_PIPELINE_FAILED will be set to "1" if the pipeline failed because an action has exited with a non-zero status (and did not have the IGNORE_EXIT_STATUS flag set). This can be used to determine if additional debug or logging actions should execute. GOOGLE_LAST_EXIT_STATUS will be set to the exit status of the last non-background action that executed. This can be used by workflow engine authors to determine whether an individual action has succeeded or failed.
* flags array: The set of flags to apply to this action.
* items string (values: FLAG_UNSPECIFIED, IGNORE_EXIT_STATUS, RUN_IN_BACKGROUND, ALWAYS_RUN, ENABLE_FUSE, PUBLISH_EXPOSED_PORTS, DISABLE_IMAGE_PREFETCH, DISABLE_STANDARD_ERROR_CAPTURE)
* imageUri string: Required. The URI to pull the container image from. Note that all images referenced by actions in the pipeline are pulled before the first action runs. If multiple actions reference the same image, it is only pulled once, ensuring that the same image is used for all actions in a single pipeline. The image URI can be either a complete host and image specification (e.g., quay.io/biocontainers/samtools), a library and image name (e.g., google/cloud-sdk) or a bare image name ('bash') to pull from the default library. No schema is required in any of these cases. If the specified image is not public, the service account specified for the Virtual Machine must have access to pull the images from GCR, or appropriate credentials must be specified in the google.genomics.v2alpha1.Action.credentials field.
* labels object: Labels to associate with the action. This field is provided to assist workflow engine authors in identifying actions (for example, to indicate what sort of action they perform, such as localization or debugging). They are returned in the operation metadata, but are otherwise ignored.
mounts array: A list of mounts to make available to the action. In addition to the values specified here, every action has a special virtual disk mounted under /google that contains log files and other operational components. - /google/logs All logs written during the pipeline execution. - /google/logs/output The combined standard output and standard error of all actions run as part of the pipeline execution. - /google/logs/action//stdout The complete contents of each individual action's standard output. - /google/logs/action/*/stderr The complete contents of each individual action's standard error output.
* items Mount
* name string: An optional name for the container. The container hostname will be set to this name, making it useful for inter-container communication. The name must contain only upper and lowercase alphanumeric characters and hyphens and cannot start with a hyphen.
* pidNamespace string: An optional identifier for a PID namespace to run the action inside. Multiple actions should use the same string to share a namespace. If unspecified, a separate isolated namespace is used.
* portMappings object: A map of containers to host port mappings for this container. If the container already specifies exposed ports, use the PUBLISH_EXPOSED_PORTS flag instead. The host port number must be less than 65536. If it is zero, an unused random port is assigned. To determine the resulting port number, consult the ContainerStartedEvent in the operation metadata.
* timeout string: The maximum amount of time to give the action to complete. If the action fails to complete before the timeout, it will be terminated and the exit status will be non-zero. The pipeline will continue or terminate based on the rules defined by the ALWAYS_RUN and IGNORE_EXIT_STATUS flags.

Note that only a small amount of the end of the stream is captured here. The entire stream is stored in the /google/logs directory mounted into each action, and can be copied off the machine as described elsewhere.

$3

If the disk type is specified as local-ssd, multiple local drives are automatically combined to provide the requested size. Note, however, that each physical SSD is 375GB in size, and no more than 8 drives can be attached to a single instance.
* sourceImage string: An optional image to put on the disk before attaching it to the VM.

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 {}.

$3

* Event object: Carries information about events that occur during pipeline execution.
* description string: A human-readable description of the event. Note that these strings can change at any time without notice. Any application logic must use the information in the details field.

* timestamp string: The time at which the event occurred.

$3

* ExistingDisk object: Configuration for an existing disk to be attached to the VM.

The disk must be ext4 formatted. If all Mount references to this disk have the read_only flag set to true, the disk will be attached in read-only mode and can be shared with other instances. Otherwise, the disk will be available for writing but cannot be shared.

$3

* FailedEvent object: An event generated when the execution of a pipeline has failed. Note that other events can continue to occur after this event.
* cause string: The human-readable description of the cause of the failure.

The value is prefixed with regions//subnetworks/ unless it contains a /, in which case it is assumed to be a fully specified subnetwork resource URL. If the * character appears in the value, it is replaced with the region that the virtual machine has been allocated in.
* usePrivateAddress boolean: If set to true, do not attach a public IP address to the VM. Note that without a public IP address, additional configuration is required to allow the VM to access Google services. See https://cloud.google.com/vpc/docs/configure-private-google-access for more information.

$3

The default value is projects/cos-cloud/global/images/family/cos-stable, which selects the latest stable release of Container-Optimized OS. This option is provided to allow testing against the beta release of the operating system to ensure that the new version does not interact negatively with production pipelines. To test a pipeline against the beta release of Container-Optimized OS, use the value projects/cos-cloud/global/images/family/cos-beta.
* cpuPlatform string: The CPU platform to request. An instance based on a newer platform can be allocated, but never one with fewer capabilities.
