Is Kubernetes cloud only?
3. Kubernetes is cloud-agnostic. Kubernetes runs on Amazon Web Services (AWS), Microsoft Azure, and the Google Cloud Platform (GCP), and you can also run it on premises.
Can I run Kubernetes on Windows?
Kubernetes can run Windows and Linux containers. And there's a further constraint: the Kubernetes control plane can only run on a Linux node. In other words, Kubernetes will have to run inside a Linux virtual machine to operate correctly on Windows.

What is difference between Docker and Kubernetes?
In a nutshell, Docker is a suite of software development tools for creating, sharing and running individual containers; Kubernetes is a system for operating containerized applications at scale. Think of containers as standardized packaging for microservices with all the needed application code and dependencies inside.
Can Kubernetes run without Docker?
Can Kubernetes Run Without Docker? The answer is both yes and no. Kubernetes, in itself, is not a complete solution. It depends on a container runtime to orchestrate; you can't manage containers without having containers in the first place.

Why you dont need Kubernetes?
It's simple to build and debug but doesn't scale well, and it's also tough to make changes as the application gets more complex. Kubernetes, on the other hand, requires application containerization. It is the opposite of monolithic. It means breaking large applications down into smaller services that work together.

Minikube. Minikube can run a single node cluster in a Virtual machine of your laptop. In the following sections I’ll discuss how you can configure and run a Minikube cluster in a windows environment. First to kno w ing the basics. So running minikube in your local environment spins a new VM instance in your laptop.
Can you run Kubernetes in a minikube?
So running minikube in your local environment spins a new VM instance in your laptop. Inside the VM it will create the single node cluster. The Kubernetes API server will be available outside the VM, which will enable to use the kubectl to manage the cluster inside the Minikube VM.
Why run Kubernetes locally?
Running kubernetes locally can be helpful to save costs, to use portions for CI/CD on your cloud-native applications, and to address situations when you don’t have reliable internet access and want to do “real” work. This blog post walks through the following technologies: Minikube. Docker in Docker.

What is a minikube?
Minikube. Minikube is the defacto entry point for most people learning or figuring out how to run Kubernetes on a local machine. I’ve even heard of some people using Minikube to run Dev or QA environments on shared VMs on clouds. It feels a lot like the old devstack options back in the OpenStack days.

How much RAM does Minikube have?
The previous command gives your Minikube instance two virtual CPUs, and 4 GB of RAM. This change should allow you to do more with it, like install istio, but not much more.

What is a Kubernetes pod manifest?
Okay, let's take a look at what we call a pod manifest. Now, Kubernetes manifests are the files that define the state you want applied to the Kubernetes cluster. In this case, this is a yaml file that is declaring a pod that I'd like to have Kubernetes run. Manifest files generally start with an API version and a Kind, this just basically tells Kubernetes that I'm targeting the V1 API version for this object, and that this object is a pod. Also, most objects will have metadata, and the metadata on this is... We're giving it a name, building apps pod, and we're giving a name value paired label, app KubeAcademy. So when this pod gets created, it'll be named this and it'll have a label called app whose value is KubeAcademy.
Can you run Kubernetes on a Mac?
If you're on a Mac or Windows, you can use Docker desktop to run Kubernetes, it's built in, but Kind is the method we'll use today. So let's go ahead and start up our cluster.
Can you run Kubernetes on a Docker desktop?
Minikube spins up virtual machines on your local workstation and uses those as Kubernetes nodes. If you're on a Mac or Windows, you can use Docker desktop to run Kubernetes, it's built in, but Kind is the method we'll use today. So let's go ahead and start up our cluster. In my terminal, I'm going to type Kind creates cluster. Now this could take a minute, so I'm going to go ahead and skip forward. So you don't have to sit here and watch this.
