Tekton CI/CD, part IV, continuous delivery

View Original View Raw

Summary

In this article, the author demonstrates how to deploy applications to production using Tekton CI/CD. They set up an application in Kubernetes and a Docker registry, and use Tekton tasks to build a Docker image, push the image to the registry, and perform a rollout deployment in kubernetes with kubectl. They also discuss how to configure a private Git repository and use Tekton ClusterInterceptors to filter specific events and run different pipelines.

Q&As

What is the overall purpose of the article?
The overall purpose of the article is to demonstrate how to use Tekton tasks to deploy an application to production.

What is the process for deploying an application using Tekton tasks?
The process for deploying an application using Tekton tasks is to build a Docker image of the application, push the image to the Docker registry, and perform a rollout deployment in Kubernetes using kubectl.

What is the purpose of the sidecar in the Tekton pipeline?
The purpose of the sidecar in the Tekton pipeline is to provide the Docker daemon that is running in the cluster, as well as the flag --insecure-registry to the command argument.

What does the Tekton Hub provide to set up an application in Kubernetes?
The Tekton Hub provides a Task called kubernetes-actions to install and use it as needed.

How can an application be delivered in a sustainable way?
An application can be delivered in a sustainable way by applying patches, updates in a reliable and secure way.

Technical terms

Tekton CI/CD: Tekton CI/CD is a continuous integration and continuous delivery (CI/CD) platform for Kubernetes. It enables developers to build, test, and deploy applications quickly and easily.
Kubernetes: Kubernetes is an open-source container-orchestration system for automating deployment, scaling, and management of containerized applications.
Docker: Docker is a computer program that performs operating-system-level virtualization, also known as "containerization". It is used to run software packages called "containers".
Linux: Linux is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds.
Agile: Agile is a set of values and principles for software development that promotes adaptive planning, evolutionary development, early delivery, and continuous improvement. It is an iterative and incremental approach to software development that encourages frequent inspection and adaptation.
