Quick Overview
Kubeflow Pipelines is an open-source platform for building and deploying portable, scalable machine learning (ML) workflows based on Docker containers. It provides a user interface for managing and tracking experiments, jobs, and runs, making it easier to compose, deploy, and manage complex ML pipelines.
Pros
- Seamless integration with Kubernetes for scalable and portable ML workflows
- Supports end-to-end orchestration of ML pipelines, from data preparation to model deployment
- Provides a user-friendly interface for visualizing and managing pipeline runs
- Enables easy sharing and reuse of components and pipelines across teams and projects
Cons
- Steep learning curve for users unfamiliar with Kubernetes and container technologies
- Complex setup and maintenance, especially for on-premises deployments
- Limited support for certain ML frameworks and libraries compared to some other platforms
- Resource-intensive, which may lead to higher costs for small-scale projects
Code Examples
- Defining a simple pipeline component:
from kfp.dsl import component
@component
def add_numbers(a: int, b: int) -> int:
return a + b
- Creating a pipeline using components:
from kfp.dsl import pipeline
@pipeline(name="Simple Addition Pipeline")
def addition_pipeline(a: int, b: int):
add_op = add_numbers(a, b)
print_op = print_result(add_op.output)
- Compiling and running a pipeline:
from kfp import compiler
compiler.Compiler().compile(addition_pipeline, "addition_pipeline.yaml")
client = kfp.Client()
client.create_run_from_pipeline_func(addition_pipeline, arguments={"a": 5, "b": 7})

Code Comparison
Prefect workflow definition:
@task
def process_data(data):
return data.upper()
@flow
def my_flow(input_data):
result = process_data(input_data)
return result
Kubeflow Pipelines workflow definition:
@dsl.pipeline(

Overview of the Kubeflow pipelines service
Kubeflow is a machine learning (ML) toolkit that is dedicated to making deployments of ML workflows on Kubernetes simple, portable, and scalable.
Kubeflow pipelines are reusable end-to-end ML workflows built using the Kubeflow Pipelines SDK.
The Kubeflow pipelines service has the following goals:
- End to end orchestration: enabling and simplifying the orchestration of end to end machine learning pipelines
- Easy experimentation: making it easy for you to try numerous ideas and techniques, and manage your various trials/experiments.
- Easy re-use: enabling you to re-use components and pipelines to quickly cobble together end to end solutions, without having to re-build each time.
Installation
-
Kubeflow Pipelines can be installed as part of the Kubeflow Platform. Alternatively you can deploy Kubeflow Pipelines as a standalone service.
-
The Docker container runtime has been deprecated on Kubernetes 1.20+. Kubeflow Pipelines has switched to use Emissary Executor by default from Kubeflow Pipelines 1.8. Emissary executor is Container runtime agnostic, meaning you are able to run Kubeflow Pipelines on Kubernetes cluster with any Container runtimes.
Documentation
Get started with your first pipeline and read further information in the Kubeflow Pipelines overview.
See the various ways you can use the Kubeflow Pipelines SDK.
See the Kubeflow Pipelines API doc for API specification.
Consult the Python SDK reference docs when writing pipelines using the Python SDK.
