1. Basic Interview Questions ForDocker and Kubernetes www.visualpath.in

2. What is Kubernetes? • Kubernetes is a container orchestration tool that is used for automating the tasks of managing, monitoring, scaling, and deploying containerized applications. It creates groups of containers that can be logically discovered and managed for easy operations on containers. www.visualpath.in

3. What is Docker? • Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. • Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package www.visualpath.in

4. What is the difference between Kubernetes and Docker Swarm? • Docker Swarm is a default container orchestration tool that comes with Docker. Docker Swarm can only orchestrate simple Docker containers. Kubernetes, on the other hand, helps manage much more complex software application containers. Kubernetes offers support for larger demand production environment. www.visualpath.in

5. What is Orchestration in software? • Application orchestration in software process means you can integrate two or more applications. • You will be able to automate arrangement, coordination, and management of computer software. • The goal of any orchestration process is to streamline and optimize frequent repeatable processes. www.visualpath.in

6. What is a node in Kubernetes? • A node in Kubernetes is a worker machine which is also known as a minion. • This node could be a physical machine or a virtual machine. For each of the node, there is a service to run pods, and it is managed by master components. • The node services could include kubelet, kube-proxy, and so on. www.visualpath.in

7. What is Kubelet? • You can think of Kubelet as the lowest level component in a Kubernetes. • The Kubelet is responsible for making the individual machines to run. • The sole purpose of a Kubelet is that in a given a set of containers, it has to ensure that they are all running.

8. Docker Client: • This performs Docker build pull and run operations to establish communication with the Docker Host. The Docker command uses Docker API to call the queries to be run. www.visualpath.in

9. Docker Host • This component contains Docker Daemon, Containers and its images. • The images will be the kind of metadata for the applications which are containerized in the containers. www.visualpath.in

10. What is Docker Container? A Docker Container is a form of encapsulation to the application which holds all the dependencies which share the kernel with other containers in the duration of running the isolated processes on the host operating system. A Docker container can be created by creating a Docker image. These Docker images can be run after that using Docker Commands www.visualpath.in

11. Docker containers are the instances of the Docker images at the runtime.Docker images can be stored in any public hosts or private hosts like Docker hub. Docker Image is a set of files which can be run in an isolated process. www.visualpath.in

12. What is a Docker image? A Docker image is a file, comprised of multiple layers, used to execute code in a Docker container. An image is essentially built from the instructions for a complete and executable version of an application, which relies on the host OS kernel. www.visualpath.in

13. Why is Kubernetes important? • Kubernetes is an open source container orchestration platform, allowing large numbers of containers to work together in harmony, reducing operational burden. It helps with things like Running containers across many different machines. www.visualpath.in
