Creating a CI/CD pipeline for Kubernetes with Azure Pipelines

So far, we have seen how to use kubectl to deploy a containerized application in a local K8S cluster, or in a remote cluster with AKS.

Now, we will see how to create a complete CI/CD pipeline for Kubernetes, from the creation of a new Docker image pushed in the Docker Hub, to its deployment in an AKS cluster.
