Build in continuous integration, delivery and deploy
1 like374 views
This document discusses building continuous integration and continuous delivery (CI/CD) pipelines for containerized applications using Docker, Kubernetes, Jenkins, and Azure Kubernetes Service (AKS). It provides an example of setting up a CI/CD pipeline for a sample quiz application using a local Minikube Kubernetes cluster for development and testing. It then describes how to deploy the application to an AKS cluster in Azure for staging and production environments. The pipeline is configured to automatically build, test, and deploy application code on each commit via a Jenkinsfile.
