Interview Questions and Answers Basic Kubernetes
What is Kubernetes?
Kubernetes, Google’s open-source container orchestration software, can be used to help with container deployment, container scaling, descaling, load balancing, and container deployment.
What is the relationship between Kubernetes & Docker?
Docker supports container lifecycle management. The Docker image provides the foundation for runtime containers. Docker is used to build containers. Kubernetes allows for communication between them.
Define container orchestration?
Consider a situation in which you have three to four microservices that are all related to a particular application. Each microservice would now be in its own container, making it impossible for them to communicate with one another. Container orchestration allows you to coordinate the work of all containers in order to meet the needs of a specific server.
How can Kubernetes make containerized deployment easier?
General applications are a group of containers that runs on multiple hosts. Kubernetes can run on any cloud service platform, public or private. It simplifies containerized deployment by allowing for load balancing, scaling and monitoring.
What are the most important components of Kubernetes architecture
The master node and worker nodes are the two most important components of the Kubernetes architecture. Each component of the master node or worker node has its own components.
Kubernetes defines a node.
A node is a representation for a single machine within a cluster. It is the smallest unit of computing hardware. A node can be either a virtual machine, or a physical machine within a data center.
What are the processes the Kubernetes Master Node runs in?
Kubernetes’ master node runs Kube-API server processes and aids in scaling and deployment of additional instances.
Define a pod using Kubernetes.
Kubernetes has a pod, which is a high-level structure that wraps up one or more containers. Kubernetes can’t run containers directly. Containers in a pod share the same local networks and resources which allows for easy communication between them, while still remaining isolated.
Define a Kubernetes cluster of containers.
A cluster of containers is a collection of nodes. Clusters are responsible to start certain routes that allow containers on the nodes communicate with one another.
What are the benefits to Kubernetes
Kubernetes makes container management easier and allows customers to respond faster by deploying containers more quickly and predictably. Kubernetes offers the ability to automate rollback, horizontal scaling and automated scheduling and self-healing functions.
What are the components of a Kubernetes Master’s job?
The Kubernetes Master includes the API server, etcd components, and the Controller manager. These components support operations and management.
