Kubernetes Online Test Questions (Kubernetes FAQs)

1) What is kubernetes?

Kubernetes is an open-source platform that automates Linux container operations i.e. it helps in managing the clusters. It is basically used to run modern applications across multiple clusters on cloud services and data centers.

2) What can you deploy on kubernetes?

You can deploy Pods or Containers which is a set of replica on Kubernetes.

3) At its core, Kubernetes is a platform for what?

At its core, Kubernetes is a platform for running and scheduling container applications on a cluster.

4) What are kubernetes pods?

Pods in Kubernetes are the smallest and most basic deployable objects. A Pod represents a single instance of a running process in your cluster. It can contain one or more containers.

5) Kubernetes is written in which Programming language?

Kubernetes is written in Go Programming language.

6) What is a cluster of containers in Kubernetes?

A cluster is a set of nodes that run containerized applications, that packages an app with its dependencies and services such that it can easily run across multiple platforms.

A DaemonSet ensures that Nodes run a copy of a Pod i.e. if nodes are added then a new pod is created and if nodes are removed then those Pods are collected in the garbage.

8) What is 'Heapster' in Kubernetes?

Heapster is a uniform platform adopted by Kubernetes which is a cluster-wide aggregator of monitoring and performance analysis. It works on all Kubernetes setups and runs as a pod in the cluster.

9) What is the LoadBalancer in Kubernetes?

A load balancer performs the distribution of network traffic across multiple servers to optimize performance and ensure the reliability of an application.

10) What is Kube-proxy?

It is a network proxy that runs on each node in your cluster and can be implemented as Kubernetes Service. kube-proxy maintains network rules on nodes and later these network rules are used to allow network communication to your Pods from network sessions inside or outside of your cluster.
