Building modern CI/CD workflows for serverless applications with Red Hat OpenShift Pipelines and Argo CD, Part 2

Building modern CI/CD workflows for serverless applications with Red Hat OpenShift Pipelines and Argo CD, Part 2

In the first half of this article, I introduced Tekton as a framework for cloud-native CI/CD pipelines, and Argo CD as its perfect partner for GitOps on Red Hat OpenShift. Our example for the demonstration is a Knative service that deploys and serves a Quarkus application. Our goal is to develop a complete continuous integration and delivery process, which begins when a commit is initiated in the application’s GitHub repository and ends with the new application version deployed in the development, staging, and production environments.

A recent article, The present and future of CI/CD with GitOps on Red Hat OpenShift, proposed Tekton as a framework for cloud-native CI/CD pipelines, and Argo CD as its perfect partner for GitOps. GitOps practices support continuous delivery in hybrid, multi-cluster Kubernetes environments.

From code to production with OpenShift Pipelines and Argo CD

From code to production with OpenShift Pipelines and Argo CD

Our team is responsible for a small GoLang application. The application’s developers are continuously sending code changes to the main branch, so for the past two years, our team has used GitOps for continuous integration (CI). We started out using GitOps to deploy applications to our test clusters; then, we began using it to run day two operations in our clusters.

The present and future of CI/CD with GitOps on Red Hat OpenShift

The need to deliver applications faster is near-universal, even in organizations that traditionally are perceived as risk-averse. As the foundations of DevOps, continuous integration (CI) and continuous delivery (CD) are essential to application delivery in most organizations. Together, CI/CD tools and processes automate building and testing applications on every code or configuration change, then trigger a sequence of workflows that deliver the application to production.

Introduction to Tekton and Argo CD for multicluster development

Introduction to Tekton and Argo CD for multicluster development

Over the last two years, my coworkers and I have worked on developing a multicluster project for Kubernetes and Red Hat OpenShift. We needed a way to efficiently deploy applications, oversee access and authorization, and manage application placement across clusters. This need led us to develop with Argo CD and GitOps.

Recently, I switched to another team that also focuses on multicluster development. During my interviews, I promised to help create a catalog of our projects and develop a process to deploy them rapidly. Together, the catalog and process would allow the team to just work on things, rather than trying to figure out how to get them operational. However, I quickly hit a wall. With Argo CD, I couldn’t control when and in what order cluster objects were deployed onto new or existing clusters. Eventually, I discovered Tekton, a powerful addition to my development toolset.

In this article, I briefly describe my process for developing the catalog and process tool. I’ll introduce the components involved, explain a little about how Tekton Pipelines works, and leave you with a tool that you can share with your organization and teams.

OpenShift joins the Argo CD community (KubeCon Europe 2020)

OpenShift joins the Argo CD community (KubeCon Europe 2020)

As Kubernetes and Red Hat OpenShift platform adoption grow and organizations move a larger portion of their infrastructure to these platforms, organizations are increasingly faced with the challenge of managing hybrid multicluster environments across the public cloud and on-premises infrastructure. While this approach brings flexibility and scalability to managing applications, the ability to ensure configuration consistency across these clusters, and the ability to roll out applications to multiple clusters in a consistent manner becomes a necessity. Enter the Argo CD GitOps Kubernetes Operator.
