Difference Between Kubernetes and Docker

A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Kubernetes is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.

Does Kubernetes use Docker?

As Kubernetes is a container orchestrator, it needs a container runtime in order to orchestrate. Kubernetes is most commonly used with Docker, but it can also be used with any container runtime. RunC, cri-o, containerd are other container runtimes that you can deploy with Kubernetes.

Can you use Kubernetes without Docker?

The Symbiosis Between Kubernetes and Docker

One isn't an alternative to the other. Quite the contrary; Kubernetes can run without Docker and Docker can function without Kubernetes. ... Docker is what enables us to run, create and manage containers on a single operating system.

How does Kubernetes work with Docker?

Docker helps to “create” containers, and Kubernetes allows you to “manage” them at runtime. Use Docker for packaging and shipping the app. Employ Kubernetes to deploy and scale your app.

Do I need to learn Docker before Kubernetes?

You can't really do k8s without Docker, and the Docker basics are pretty easy to learn. Definitely learn Docker first. I woudn't spend time with Swarm or Compose, especially since you can install minikube easily enough. ... As you use kubernetes, it'll give you practical ways to learn docker.

Is Kubernetes a PaaS?

Kubernetes is not a traditional, all-inclusive PaaS (Platform as a Service) system. ... Kubernetes aims to support an extremely diverse variety of workloads, including stateless, stateful, and data-processing workloads. If an application can run in a container, it should run great on Kubernetes.

Why did Kubernetes drop Docker?

TL;DR Docker as an underlying runtime is being deprecated in favor of runtimes that use the Container Runtime Interface (CRI) created for Kubernetes. ... If you're an end-user of Kubernetes, not a whole lot will be changing for you.

Does Netflix use Kubernetes?

Netflix chose to build a dedicated container orchestration platform called Titus. ... Therefore, Netflix chose to build their Titus container management system on top of Mesophere. Today, Kubernetes has broad support for brownfield applications. For example, Docker Swarm now integrates Kubernetes into Swarm clusters.

When should you not use containers?

So, one example of when not to use containers is if a high level of security is critical. They can require more work upfront: If you're using containers right, you will have decomposed your application into its various constituent services, which, while beneficial, isn't necessary if you are using VMs.

Is Docker still popular?

As per the Containerization Market Share Report, Docker is the second market-leading technology with a 25.80% market share in the market, and the first is LXC with a 39.50% market share. Over the other top technologies such as packer, Kubernetes, Red Hat OpenShift Docket stands excellent in the market.

When should I use Docker?

When To Use Docker?
