Args:
host: Host name to use to talk to Kubeflow Pipelines. If not set,
the in-cluster service DNS name will be used, which only works if
the current environment is a pod in the same cluster (such as a
Jupyter instance spawned by Kubeflow's JupyterHub). (`More information on connecting. <https://www.kubeflow.org/docs/components/pipelines/sdk/connect-api/>`_)
client_id: Client ID used by Identity-Aware Proxy.
namespace: Kubernetes namespace to use. Used for multi-user deployments. For single-user deployments, this should be left as ``None``.
other_client_id: Client ID used to obtain the auth codes and refresh
tokens (`reference <https://cloud.google.com/iap/docs/authentication-howto#authenticating_from_a_desktop_app>`_).
other_client_secret: Client secret used to obtain the auth codes and
refresh tokens.
existing_token: Authentication token to pass in directly. Used in cases where the token is
generated from outside the SDK.
cookies: CookieJar object containing cookies that will be passed to the
Pipelines API.
proxy: HTTP or HTTPS proxy server.
ssl_ca_cert: Certification for proxy.
kube_context: kubectl context to use. Must be a context listed in the kubeconfig file. Defaults to the current-context set within kubeconfig.
credentials: ``TokenCredentialsBase`` object which provides the logic to
populate the requests with credentials to authenticate against the
API server.
ui_host: Base URL to use to open the Kubeflow Pipelines UI. This is used
when running the client from a notebook to generate and print links.
verify_ssl: Whether to verify the server's TLS certificate.

description: Description of the job.
start_time: RFC3339 time string of the time when to start the
job.
end_time: RFC3339 time string of the time when to end the job.
interval_second: Integer indicating the seconds between two
recurring runs in for a periodic schedule.
cron_expression: Cron expression representing a set of times,
using 6 space-separated fields (e.g., ``'0 0 9 ? * 2-6'``). See `cron format
<https://pkg.go.dev/github.com/robfig/cron#hdr-CRON_Expression_Format>`_.
max_concurrency: Integer indicating how many jobs can be run in
parallel.
no_catchup: Whether the recurring run should catch up if behind
schedule. For example, if the recurring run is paused for a
while and re-enabled afterwards. If ``no_catchup=False``, the
scheduler will catch up on (backfill) each missed interval.
Otherwise, it only schedules the latest interval if more than
one interval is ready to be scheduled. Usually, if your pipeline
handles backfill internally, you should turn catchup off to
avoid duplicate backfill.
pipeline_package_path: Local path of the pipeline package (the
filename should end with one of the following .tar.gz, .tgz,
.zip, .json).
params: Arguments to the pipeline function provided as a dict.
pipeline_id: ID of a pipeline.
version_id: ID of a pipeline version.
If both ``pipeline_id`` and ``version_id`` are specified, ``version_id``
will take precedence.
If only ``pipeline_id`` is specified, the default version of this
pipeline is used to create the run.
enabled: Whether to enable or disable the recurring run.
pipeline_root: Root path of the pipeline outputs.
enable_caching: Whether or not to enable caching for the
run. If not set, defaults to the compile time settings, which
is ``True`` for all tasks by default, while users may specify
different caching options for individual tasks. If set, the
setting applies to all tasks in the pipeline (overrides the
compile time settings).

account this recurring run uses.
