## Instance Methods

Close httplib2 connections.

Runs a pipeline. The returned Operation's metadata field will contain a google.cloud.lifesciences.v2beta.Metadata object describing the status of the pipeline execution. The response field will contain a google.cloud.lifesciences.v2beta.RunPipelineResponse object if the pipeline completes successfully. **Note:** Before you can use this method, the *Life Sciences Service Agent* must have access to your project. This is done automatically when the Cloud Life Sciences API is first enabled, but if you delete this permission you must disable and re-enable the API to grant the Life Sciences Service Agent the required permissions. Authorization requires the following [Google IAM](https://cloud.google.com/iam/) permission: * `lifesciences.workflows.run`

    Args:
      parent: string, The project and location that this request should be executed against. (required)
      body: object, The request body.
        The object takes the form of:

    { # The arguments to the `RunPipeline` method. The requesting user must have the `iam.serviceAccounts.actAs` permission for the Cloud Life Sciences service account or the request will fail.
        "labels": { # User-defined labels to associate with the returned operation. These labels are not propagated to any Google Cloud Platform resources used by the operation, and can be modified at any time. To associate labels with resources created while executing the operation, see the appropriate resource message (for example, `VirtualMachine`).
          "a_key": "A String",
        },
        "pipeline": { # Specifies a series of actions to execute, expressed as Docker containers. # Required. The description of the pipeline to run.
          "environment": { # The environment to pass into every action. Each action can also specify additional environment variables but cannot delete an entry from this map (though they can overwrite it with a different value).
            "a_key": "A String",
          },
          "actions": [ # The list of actions to execute, in the order they are specified.
            { # Specifies a single action that runs a Docker container.
              "imageUri": "A 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.cloud.lifesciences.v2beta.Action.credentials field.
              "alwaysRun": True or False, # By default, after an action fails, no further actions are run. This flag indicates that this action must be run even if the pipeline has already failed. This is useful for actions that copy output files off of the VM or for debugging. Note that no actions will be run if image prefetching fails.
              "credentials": { # Holds encrypted information that is only decrypted and stored in RAM by the worker VM when running the pipeline. # If the specified image is hosted on a private registry other than Google Container Registry, the credentials required to pull the image must be specified here as an encrypted secret. The secret must decrypt to a JSON-encoded dictionary containing both `username` and `password` keys.
                "keyName": "A String", # The name of the Cloud KMS key that will be used to decrypt the secret value. The VM service account must have the required permissions and authentication scopes to invoke the `decrypt` method on the specified key.
                "cipherText": "A String", # The value of the cipherText response from the `encrypt` method. This field is intentionally unaudited.
              },
              "containerName": "A 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.
              "enableFuse": True or False, # Enable access to the FUSE device for this action. Filesystems can then be mounted into disks shared with other actions. The other actions do not need the `enable_fuse` flag to access the mounted filesystem. This has the effect of causing the container to be executed with `CAP_SYS_ADMIN` and exposes `/dev/fuse` to the container, so use it only for containers you trust.
              "commands": [ # 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.
                "A String",
              ],
              "ignoreExitStatus": True or False, # Normally, a non-zero exit status causes the pipeline to fail. This flag allows execution of other actions to continue instead.
              "disableStandardErrorCapture": True or False, # A small portion of the container's standard error stream is typically captured and returned inside the `ContainerStoppedEvent`. Setting this flag disables this functionality.
              "disableImagePrefetch": True or False, # All container images are typically downloaded before any actions are executed. This helps prevent typos in URIs or issues like lack of disk space from wasting large amounts of compute resources. If set, this flag prevents the worker from downloading the image until just before the action is executed.
              "labels": { # 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.

              },
              "pidNamespace": "A 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.
              "environment": { # The environment to pass into the container. This environment is merged with values specified in the google.cloud.lifesciences.v2beta.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.
                "a_key": "A String",
              },
              "runInBackground": True or False, # This flag allows an action to continue running in the background while executing subsequent actions. This is useful to provide services to other actions (or to provide debugging support tools like SSH servers).
              "timeout": "A 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.
              "publishExposedPorts": True or False, # Exposes all ports specified by `EXPOSE` statements in the container. To discover the host side port numbers, consult the `ACTION_STARTED` event in the operation metadata.
