Kubernetes and docker TRAINING IN CHENNAI
KUBERNETES AND DOCKER TRAINING IN CHENNAI
INTRO TO KUBERNETES AND DOCKER
Kubernetes is an open-source container orchestration system for managing, scaling, and deploying software. Kubernetes was created by Google, but it is now maintained by the Cloud Native Computing Foundation. It has a huge and fast-expanding ecosystem. Services, support, and tools for Kubernetes are widely available. It is a framework for managing containerized workloads and services that allows declarative configuration as well as automation. Kubernetes can scale applications and supporting infrastructure resources up or down based on the organization’s changing needs, making dynamic peak management easier. It is based on Google’s 15-year experience operating containerized workloads and the open-source community’s contributions. Kubernetes, which was inspired by Google’s internal cluster management solution, Borg, simplifies the process of deploying and administering your application. It increases your reliability by automating container orchestration and reducing the time and resources spent on everyday operations. Learn Kubernetes from the best Kubernetes Training Institute in Chennai with real time project based training.
Kubernetes is an open-source container orchestration platform with an API for controlling how and where those containers execute.

Kubernetes FQA
What is Kubernetes in simple words?
Kubernetes is an open-source framework for managing containerized workloads and services that allows declarative configuration as well as automation. It has a huge and fast-expanding ecosystem. Services, support, and tools for Kubernetes are widely available.
Is Kubernetes using Docker?
The Kubernetes server is exclusively for local testing and operates in a Docker container on your local system. You can deploy your workloads in parallel, on Kubernetes, Swarm, and as standalone containers after enabling Kubernetes. Your other workloads are unaffected by enabling or disabling the Kubernetes server.
How do Docker and Kubernetes work together?
Docker makes it easier to “build” containers, whereas Kubernetes makes it possible to “manage” them in real-time. To package and ship the software, use Docker. To launch and scale your app, use Kubernetes.
Is Kubernetes better than Docker?
Kubernetes and Docker are more powerful when used together.
While the promise of containers is that you can write code once and execute it anywhere, Kubernetes allows you to coordinate and manage all of your container resources from a single control plane.
Are Kubernetes and Docker the same?
Kubernetes and Docker are two fundamentally different technologies that complement each other when it comes to developing, deploying, and scaling containerized apps.
What Kubernetes is used for?
Kubernetes, often known as “K8s,” orchestrates the execution of containerized applications over a cluster of hosts. Using on-premises infrastructure or public cloud platforms, the K8s solution automates the deployment and administration of cloud-native apps.
Does AWS use it?
AWS makes running Kubernetes simple. According to the Cloud Native Computing Federation, AWS has the most customers running Kubernetes in the cloud, with the bulk of Kubernetes deployments operating on AWS.
Should I learn Kubernetes?
Kubernetes is in high demand, and it’s critical for developers to understand the platform in order to design scalable apps and deploy them quickly.

Certifications
The Cloud Native Computing Foundation has a certification program that allows users to demonstrate their command-line skills in a practical environment. The Certified Kubernetes Administrator (CKA) program’s goal is to ensure that CKAs have the necessary skills, knowledge, and competency to perform Kubernetes administrator tasks. It’s an online, proctored, performance-based test that needs you to use a command line to solve various problems.
CKS is a performance-based certification exam that assesses candidates’ understanding of Kubernetes and cloud security in a realistic, simulated environment. CKS can be purchased, but it cannot be scheduled until CKA certification is obtained. On the date the CKS exam (including retakes) is planned, the CKA certification must be active (not expired).
