What is Kubernetes?

Kubernetes is an open-source container orchestration platform that enables the operation of an elastic web server framework for cloud applications. Kubernetes can support data center outsourcing to public cloud service providers or can be used for web hosting at scale.

What kind of applications can be run on Kubernetes?

Featured Kubernetes applications

• GitLab. A single application for all stages of the DevOps lifecycle.
• CloudBees. CI/CD automation engine for growing organizations.
• Neo4j. Graph database management system.
• Seldon. Machine-learning deployment for Kubernetes.
• Aerospike.
• Couchbase.
• WordPress.
• Prometheus.

What is Kubernetes in DevOps?

Kubernetes is a reliable container cluster management tool. Anywhere from load testing websites, or creating a staging environment, to moving business and online applications to production, Kubernetes clusters can manage it. Cluster computing affords DevOps numerous advantages over other computing environments.

What is the advantages of Kubernetes?

Benefits of Kubernetes for companies: Control and automate deployments and updates. Save money by optimizing infrastructural resources thanks to the more efficient use of hardware. Orchestrate containers on multiple hosts.

What is Kubernetes deployment?

A Kubernetes deployment is a resource object in Kubernetes that provides declarative updates to applications. A deployment allows you to describe an application’s life cycle, such as which images to use for the app, the number of pods there should be, and the way in which they should be updated.

What is Kubernetes and how it works?

Kubernetes keeps track of your container applications that are deployed into the cloud. It restarts orphaned containers, shuts down containers when they’re not being used, and automatically provisions resources like memory, storage, and CPU when necessary.

How do applications run on Kubernetes?

A pod is the basic execution unit of a Kubernetes application. A pod is also the smallest schedulable item in a Kubernetes application. If Kubernetes is an operating system , a pod represents a set of processes — where each process may be mapped to a container — running on the cluster.

What is Kubernetes in AWS?

Kubernetes is open source software that allows you to deploy and manage containerized applications at scale. Kubernetes manages clusters of Amazon EC2 compute instances and runs containers on those instances with processes for deployment, maintenance, and scaling.

Is Kubernetes used for deployment?

A Kubernetes Deployment is used to tell Kubernetes how to create or modify instances of the pods that hold a containerized application. Deployments can scale the number of replica pods, enable rollout of updated code in a controlled manner, or roll back to an earlier deployment version if necessary.

How do you run deployment in Kubernetes?

Creating Deployments You can create a Deployment using the kubectl apply , or kubectl create commands. Once created, the Deployment ensures that the desired number of Pods are running and available at all times. The Deployment automatically replaces Pods that fail or are evicted from their nodes.

What are Kubernetes resources?

A resource is an endpoint in the Kubernetes API that stores a collection of API objects of a certain kind; for example, the built-in pods resource contains a collection of Pod objects. A custom resource is an extension of the Kubernetes API that is not necessarily available in a default Kubernetes installation.

What is Kubernetes basic?

Kubernetes, at its basic level, is a system for running and coordinating containerized applications across a cluster of machines. It is a platform designed to completely manage the life cycle of containerized applications and services using methods that provide predictability, scalability, and high availability.
