What is Kubernetes and what problem does it solve?
Kubernetes is an open-source container orchestration platform that automates deployment, scaling, and management of...
Explain the concept of pods in Kubernetes.
Pods are the smallest deployable units in Kubernetes, consisting of one or more containers that share storage,...
What are Kubernetes services and how do they work?
Services expose a set of pods as a network service, enabling load balancing and stable networking endpoints.
Describe the role of the Kubernetes control plane.
The control plane manages the cluster state, schedules workloads, and handles API requests.
How does Kubernetes manage scaling of applications?
Kubernetes supports manual and automatic scaling using Horizontal Pod Autoscalers based on metrics like CPU utilization.
What is a ConfigMap and how is it used?
ConfigMaps store configuration data in key-value pairs that can be consumed by pods.
Explain persistent storage in Kubernetes.
Persistent storage allows data to persist beyond the lifecycle of a pod using PersistentVolumes and PersistentVolumeClaims.
How does Kubernetes ensure high availability?
High availability is ensured through replication of pods, multiple masters, and self-healing capabilities.
What are namespaces in Kubernetes and why are they useful?
Namespaces provide a way to divide cluster resources between multiple users or teams.
Describe how rolling updates are handled in Kubernetes.
Rolling updates update pods incrementally with zero downtime by gradually replacing old pods with new ones.
