Kubernetes 面试题与答案
问题 16. Explain the concept of Horizontal Pod Autoscaling (HPA) in Kubernetes.
HPA automatically adjusts the number of replica Pods in a deployment based on observed CPU utilization or custom metrics. It ensures optimal resource utilization and application performance.
问题 17. What is a Kubernetes Helm Chart?
Helm is a package manager for Kubernetes that simplifies the deployment and management of applications. A Helm Chart is a collection of pre-configured Kubernetes resources packaged for easy deployment.
问题 18. Explain the concept of Kubernetes Labels and Selectors.
Labels are key-value pairs attached to objects (e.g., Pods). Selectors are used to filter and find objects based on labels, facilitating grouping and categorization of resources.
问题 19. What is the purpose of the Kubernetes Init Container?
An Init Container is a specialized container that runs before the main application container starts. It is often used for setup tasks, such as database migrations or configuration fetching.
问题 20. Explain the difference between a DaemonSet and a Deployment in Kubernetes.
A DaemonSet ensures that all or some nodes run a copy of a Pod, while a Deployment is used for stateless applications. DaemonSets are typically used for background tasks or system-level services.
