What is Helm vs Kubernetes?
Kubernetes:
With this analogy, think of the Kubernetes cluster as an OS; Helm is the tool that enables users to install an application on that Kubernetes cluster Helm is a packaging format that works well with simple applications like stateless microservices and REST-based APIs with states stored externally in the cloud.

Can Kubernetes run on Windows?
Kubernetes:
Kubernetes can run Windows and Linux containers However, you can only run Windows containers on Windows nodes and Linux containers on Linux nodes. And there’s a further constraint: the Kubernetes control plane can only run on a Linux node.
Is Kubernetes pod a VM?
Kubernetes:
Pods always run on Nodes. A Node is a worker machine in Kubernetes and may be a VM or a physical machine, depending on the cluster Each Node runs Pods and is managed by the Master. On a Node you can have multiple pods.
Is pod and container same?
Pod:
“ A container runs logically in a pod (though it also uses a container runtime); A group of pods, related or unrelated, run on a cluster. A pod is a unit of replication on a cluster; A cluster can contain many pods, related or unrelated [and] grouped under the tight logical borders called namespaces.”.
What is POD and Node?

Pods are simply the smallest unit of execution in Kubernetes, consisting of one or more containers, each with one or more application and its binaries. Nodes are the
physical servers
or VMs that comprise a Kubernetes Cluster.
What is Kubernetes vs Jenkins?
Kubernetes:
Kubernetes automates computer applications with the external help of CI/CD. Docker is used for building and running multiple transferable environments, whereas Jenkins is an automated software testing tool for your app On the other hand, Kubernetes is a system for automating deployment, scaling, and management.
Is Kubernetes a server?
Kubernetes:
You can say that Kubernetes/OpenShift is the new Linux or even that ” Kubernetes is the new application server” But the fact is that an application server/runtime + OpenShift/Kubernetes + Istio has become the “de facto” cloud-native application platform!.
