Скачать или смотреть Kubernetes CKA Practice Question #12 – Creating a Deployment with Pods Simulating DaemonSet Behavior

In this walkthrough video, I solve Certified Kubernetes Administrator (CKA) Practice Question #12, where we create a Deployment named deploy-important in the project-tiger Namespace with the label id=very-important. The Deployment will have 3 replicas using the image nginx:1.17.6-alpine, but here's the twist: only one Pod from the Deployment will run on each worker node (we have two worker nodes: kind-control-plane and kind-worker), and the third Pod won't be scheduled unless a new worker node is added. This setup mimics DaemonSet behavior but uses a Deployment with a fixed number of replicas.

If you're studying for the CKA exam or looking to enhance your Kubernetes skills, this is a great example to learn about advanced Deployment strategies and resource distribution in Kubernetes clusters.

Key topics covered:
Creating a Kubernetes Deployment
Using labels to organize and manage Pods
Replicating DaemonSet behavior with a Deployment and fixed replicas
Managing Pods across multiple nodes in a cluster
