Using the TFX Command-line Interface

The TFX command-line interface (CLI) performs a full range of pipeline actions using pipeline orchestrators, such as Kubeflow Pipelines, Vertex Pipelines. Local orchestrator can be also used for faster development or debugging. Apache Beam and Apache airflow is supported as experimental features. For example, you can use the CLI to:

  • Create, update, and delete pipelines.
  • Run a pipeline and monitor the run on various orchestrators.
  • List pipelines and pipeline runs.

Note

The TFX CLI doesn't currently provide compatibility guarantees. The CLI interface might change as new versions are released.

About the TFX CLI

The TFX CLI is installed as a part of the TFX package. All CLI commands follow the structure below:

tfx <command-group> <command> <flags>

The following command-group options are currently supported:

  • tfx pipeline - Create and manage TFX pipelines.
  • tfx run - Create and manage runs of TFX pipelines on various orchestration platforms.
  • tfx template - Experimental commands for listing and copying TFX pipeline templates.

Each command group provides a set of commands. Follow the instructions in the pipeline commands, run commands, and template commands sections to learn more about using these commands.

Warning

Currently not all commands are supported in every orchestrator. Such commands explicitly mention the engines supported.

Flags let you pass arguments into CLI commands. Words in flags are separated with either a hyphen (-) or an underscore (_). For example, the pipeline name flag can be specified as either --pipeline-name or --pipeline_name. This document specifies flags with underscores for brevity. Learn more about flags used in the TFX CLI.

tfx pipeline

The structure for commands in the tfx pipeline command group is as follows:

tfx pipeline command required-flags [optional-flags]

Use the following sections to learn more about the commands in the tfx pipeline command group.

create

Creates a new pipeline in the given orchestrator.

Usage:

tfx pipeline create --pipeline_path=pipeline-path [--endpoint=endpoint --engine=engine \
--iap_client_id=iap-client-id --namespace=namespace \
--build_image --build_base_image=build-base-image]
--pipeline_path=pipeline-path
The path to the pipeline configuration file.
--endpoint=endpoint

(Optional.) Endpoint of the Kubeflow Pipelines API service. The endpoint of your Kubeflow Pipelines API service is the same as URL of the Kubeflow Pipelines dashboard. Your endpoint value should be something like:

https://host-name/pipeline

If you do not know the endpoint for your Kubeflow Pipelines cluster, contact you cluster administrator.

If the --endpoint is not specified, the in-cluster service DNS name is used as the default value. This name works only if the CLI command executes in a pod on the Kubeflow Pipelines cluster, such as a Kubeflow Jupyter notebooks instance.

--engine=engine

(Optional.) The orchestrator to be used for the pipeline. The value of engine must match on of the following values:

  • kubeflow: sets engine to Kubeflow
  • local: sets engine to local orchestrator
  • vertex: sets engine to Vertex Pipelines
  • airflow: (experimental) sets engine to Apache Airflow
  • beam: (experimental) sets engine to Apache Beam

If the engine is not set, the engine is auto-detected based on the environment.

Important Note

The orchestrator required by the DagRunner in the pipeline config file must match the selected or autodetected engine. Engine auto-detection is based on user environment. If Apache Airflow and Kubeflow Pipelines are not installed, then the local orchestrator is used by default.

--iap_client_id=iap-client-id
(Optional.) Client ID for IAP protected endpoint when using Kubeflow Pipelines.
--namespace=namespace
(Optional.) Kubernetes namespace to connect to the Kubeflow Pipelines API. If the namespace is not specified, the value defaults to kubeflow.
--build_image

(Optional.) When the engine is kubeflow or vertex, TFX creates a container image for your pipeline if specified. Dockerfile in the current directory will be used, and TFX will automatically generate one if not exists.

The built image will be pushed to the remote registry which is specified in KubeflowDagRunnerConfig or KubeflowV2DagRunnerConfig.

--build_base_image=build-base-image

(Optional.) When the engine is kubeflow, TFX creates a container image for your pipeline. The build base image specifies the base container image to use when building the pipeline container image.

Examples

Kubeflow:

tfx pipeline create --engine=kubeflow --pipeline_path=pipeline-path \
--iap_client_id=iap-client-id --namespace=namespace --endpoint=endpoint \
--build_image

Local:

tfx pipeline create --engine=local --pipeline_path=pipeline-path

Vertex:

tfx pipeline create --engine=vertex --pipeline_path=pipeline-path \
--build_image

To autodetect engine from user environment, simply avoid using the engine flag like the example below. For more details, check the flags section.

tfx pipeline create --pipeline_path=pipeline-path

update

Updates an existing pipeline in the given orchestrator.

Usage:

tfx pipeline update --pipeline_path=pipeline-path [--endpoint=endpoint --engine=engine \
--iap_client_id=iap-client-id --namespace=namespace --build_image]
--pipeline_path=pipeline-path
The path to the pipeline configuration file.

  • beam: (experimental) sets engine to Apache Beam

If the engine is not set, the engine is auto-detected based on the environment.

Important Note

The orchestrator required by the DagRunner in the pipeline config file must match the selected or autodetected engine. Engine auto-detection is based on user environment. If Apache Airflow and Kubeflow Pipelines are not installed, then the local orchestrator is used by default.

--iap_client_id=iap-client-id
(Optional.) Client ID for IAP protected endpoint.
--namespace=namespace
(Optional.) Kubernetes namespace to connect to the Kubeflow Pipelines API. If the namespace is not specified, the value defaults to kubeflow.

Understanding TFX CLI Flags

Common flags

--engine=engine

The orchestrator to be used for the pipeline. The value of engine must match on of the following values:

  • kubeflow: sets engine to Kubeflow
  • local: sets engine to local orchestrator
  • vertex: sets engine to Vertex Pipelines
  • airflow: (experimental) sets engine to Apache Airflow
  • beam: (experimental) sets engine to Apache Beam

If the engine is not set, the engine is auto-detected based on the environment.

Important Note

--pipeline_name=pipeline-name
The name of the pipeline.
--pipeline_path=pipeline-path
The path to the pipeline configuration file.
--run_id=run-id
Unique identifier for a pipeline run.

Kubeflow specific flags

--endpoint=endpoint

Endpoint of the Kubeflow Pipelines API service. The endpoint of your Kubeflow Pipelines API service is the same as URL of the Kubeflow Pipelines dashboard. Your endpoint value should be something like:

https://host-name/pipeline

If you do not know the endpoint for your Kubeflow Pipelines cluster, contact you cluster administrator.

If the --endpoint is not specified, the in-cluster service DNS name is used as the default value. This name works only if the CLI command executes in a pod on the Kubeflow Pipelines cluster, such as a Kubeflow Jupyter notebooks instance.

--iap_client_id=iap-client-id
Client ID for IAP protected endpoint.
--namespace=namespace
Kubernetes namespace to connect to the Kubeflow Pipelines API. If the namespace is not specified, the value defaults to kubeflow.

Generated files by TFX CLI

When pipelines are created and run, several files are generated for pipeline management.

  • ${HOME}/tfx/local, beam, airflow, vertex
    • Pipeline metadata read from the configuration is stored under ${HOME}/tfx/${ORCHESTRATION_ENGINE}/${PIPELINE_NAME}. This location can be customized by setting environment varaible like AIRFLOW_HOME or KUBEFLOW_HOME. This behavior might be changed in future releases. This directory is used to store pipeline information including pipeline ids in the Kubeflow Pipelines cluster which is needed to create runs or update pipelines.
    • Before TFX 0.25, these files were located under ${HOME}/${ORCHESTRATION_ENGINE}. In TFX 0.25, files in the old location will be moved to the new location automatically for smooth migration.
    • From TFX 0.27, kubeflow doesn't create these metadata files in local filesystem. However, see below for other files that kubeflow creates.
  • (Kubeflow only) Dockerfile and a container image
    • Kubeflow Pipelines requires two kinds of input for a pipeline. These files are generated by TFX in the current directory.
    • One is a container image which will be used to run components in the pipeline. This container image is built when a pipeline for Kubeflow Pipelines is created or updated with --build-image flag. TFX CLI will generate Dockerfile if not exists, and will build and push a container image to the registry specified in KubeflowDagRunnerConfig.
