The Tekton Pipelines Beta release

Tekton is a powerful and flexible open-source framework for creating CI/CD systems, allowing developers to build, test, and deploy across cloud providers and on-premise systems. The project recently released its Beta, which creates higher levels of stability by bringing the best features into the Pipelines Beta and brings more trust between the users and the features.


Tekton is used for infrastructure development on top of Kubernetes; it provides an open source framework for creating CI/CD systems, easily allowing developers to build, test, and deploy applications across applications.

With the new Beta functionality, users can rest assured that Beta features will not be removed, and that there will be a 9-month window dedicated to finding solutions for incompatible API changes. Since many in the Tekton community are using Tekton Pipelines to run APIs, this new release helps guarantee that any new developments on top of Tekton are reliable and optimized for best performance, with a budget of several months to make any necessary adjustments.

As platform builders require a stable API and feature set, the Beta launch includes Tasks, ClusterTasks and TaskRuns, Pipelines and PipelineRuns, to provide a foundation that users can rely on. Google created working groups in conjunction with other contributors from various companies to drive the Beta release. The team continues to churn out new Pipeline features towards a GA launch at the end of the year, while also focussing on bringing other components like metadata storage, Triggers, and the Catalog to Beta.


While initially starting as part of the Knative project from Google, in collaboration with developers from other organizations, Tekton was donated to the Continuous Delivery Foundation (CDF) in early 2019. Tekton’s initial design for the interface was even inspired by the Cloud Build API—and to this day—Google remains heavily involved in the commitment to develop Tekton, by participating in the governing board, and staffing a dedicated team invested in the success of this project. These characteristics make Tekton a prime example of a collaboration in open source.

Since its launch in February 2019, Tekton has had 3712 pull requests from 262 contributors across 39 companies spanning 16 countries. Many widely used projects across the open source industry are built on Tekton:
  • Puppet Project Nebula
  • Jenkins X
  • Red Hat OpenShift Pipelines
  • IBM Cloud Continuous Delivery
  • Kabanero – open source project led by IBM
  • Rio – open source project led by Rancher
  • Kf – open source project led by Google
Interested in trying out Tekton yourself? To install Tekton in your own kubernetes cluster (1.15 or newer), use kubectl to install the latest Tekton release:

kubectl apply -f
https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml

You can jump right in by saving this Task to a file called task.yaml:

apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
  name: hello-world
spec:
  steps:
  - image: ubuntu
    script: |
      echo "hello world"


Tasks are one of the most important building blocks of Tekton! Head over to tektoncd/catalog for more examples of reusable Tasks.

To run the hello-world Task, first apply it to your cluster with kubectl:

kubectl apply -f task.yaml

The easiest way to start running our Task is to use the Tekton command line tool, tkn. Install tkn using the right method for your OS, and you can run your Task with:

tkn task start hello-world --showlog

That’s just a taste of Tekton! At tekton.dev/try the community is hard at work adding interactive tutorials that let you try Tekton in a virtual environment. And you can dump straight into the docs at tekton.dev/docs and join the Tekton community at github.com/tektoncd/community.

Congratulations to all the contributors who made this Beta release possible!

Introducing the Continuous Delivery Foundation, the new home for Tekton, Jenkins, Jenkins X and Spinnaker

We're excited to announce that Google is a founding member of the newly formed Continuous Delivery Foundation (CDF). Continuous delivery (CD) is a critical part of modern software development and DevOps practices, and we're excited to collaborate in a vendor-neutral foundation with other industry leaders.

We're also thrilled to announce the contribution of two projects as part of our membership: Tekton, and in collaboration with Netflix, Spinnaker. These donations will enter alongside Jenkins and Jenkins X, providing an exciting portfolio of projects for the CDF to expand upon.

Continuous Delivery Foundation

Currently, the continuous integration/continuous delivery (CI/CD) tool landscape is highly fragmented. As companies migrate to the cloud and modernize their infrastructure, tooling decisions become increasingly complicated and difficult. DevOps practitioners constantly seek guidance on software delivery best practices and how to secure their software supply chains but gathering this information can be difficult. Enter the CDF.

The CDF is about more than just code. Modern application development brings new challenges around security and compliance. This foundation will work to define the practices and guidelines that, together with tooling, will help application developers everywhere deliver better and more secure software at speed.

At a foundation level, the CDF will help make CI/CD tooling easier. And at a project level, Tekton helps address complexity problems at their core. We will team up with the open source community and industry leaders to design and build the critical pieces common to CI/CD systems.

Tekton

Tekton is a set of shared, open source components for building CI/CD systems. It provides a flexible, extensible workflow that accommodates deployment to Kubernetes, VMs, bare metal, mobile or even emerging use cases.

The project’s goal is to provide industry specifications for pipelines, workflows, source code access and other primitives. It modernizes the continuous delivery control plane by leveraging all of the built-in scaling, reliability, and extensibility advantages of Kubernetes, and moves software deployment logic there. Tekton was initially built as a part of Knative, but given its stand-alone power, and ability to deploy to a variety of targets, we’ve decided to separate its functionality out into a new project.

Today, Tekton includes primitives for pipeline definition, source code access, artifact management, and test execution. The project roadmap includes adding support for results and event triggering in the coming months. We also plan to work with CI/CD vendors to build out an ecosystem of components that will allow you to use Tekton with existing tools like Jenkins X, Knative and others.

Spinnaker

Spinnaker is an open source, multi-cloud continuous delivery platform originally created by Netflix and jointly led by Netflix and Google. It is typically used in organizations at scale, where DevOps teams support multiple development teams, and has been battle-tested in production by hundreds of teams and in millions of deployments.

Spinnaker is a multi-component system that conceptually aligns with Tekton, and that includes many features important to making continuous delivery reliable, including support for advanced deployment strategies, and Kayenta, an open source canary analysis service.

Given Google’s significant contributions to both Tekton and Spinnaker, we’re very pleased to see them become part of the same foundation. Spinnaker’s large user community has a great deal of experience in the continuous delivery domain, and joining the CDF provides a great opportunity to share that expertise with the broader community.

Next Steps

To learn more about the CDF, listen to this week's Kubernetes Podcast from Google, where the guest is Tracy Miranda, Director of Open Source Community from our partner CloudBees.

If you'd like to participate in the future of Tekton, Spinnaker, or the CDF, please join us in Barcelona, Spain, on May 20th at the Continuous Delivery Summit ahead of KubeCon/CloudNativeCon EU. If you can’t make it, don’t worry, as there will be many opportunities to get involved and become a part of the community.

We look forward to working with the continuous delivery community on shaping the next wave of CI/CD innovations, alignments, and improvements, no matter where your applications are delivered to.
