❓ Frequently Asked Questions
What is Kubernetes and what does it do?
Kubernetes is an open-source platform that automates the deployment, scaling, and management of containerized applications.
What is a Kubernetes cluster and what are nodes?
A cluster is the set of machines (master/control plane and worker nodes) where Kubernetes runs; nodes are the machines that host and run pods.
What is a Pod in Kubernetes?
A Pod is the smallest deployable unit in Kubernetes, typically running one or more containers on a node with shared networking and storage.
What is a Deployment in Kubernetes?
A Deployment manages a desired set of Pods, ensuring their state, and handles rolling updates and rollbacks to maintain availability.
What is a Service in Kubernetes?
A Service provides a stable network endpoint for a group of Pods, enabling load balancing and service discovery.
