Deploying to Kubernetes with Actions

Welcome! In this lesson, you'll learn how to set up Continuous Deployment (CD) to Kubernetes clusters using GitHub Actions.

Automating deployments means your application changes can go live quickly and reliably, without manual steps.

We'll cover authentication, applying Kubernetes manifests, and managing updates.

Before we deploy, let's quickly recall two core Kubernetes resources:

• Deployments: These manage your application's Pods, ensuring a desired number of replicas are always running. They handle updates and rollbacks.
• Services: These define how to access your application (e.g., internally within the cluster or externally via a LoadBalancer).

Our goal is to apply YAML files defining these to our cluster from GitHub Actions.
