Kubernetes vs Docker: Which is better

Docker vs Kubernetes, a comprehensive primer

Kubernetes versus Docker is a prevalent topic and has been raised multiple times in the cloud-computing industries. Whether you have a non-technical background and only need a summary or jot down the finer points to make an important business or career decision, we hope this article will clarify your queries on this matter.

The Symbiosis Between Docker and Kubernetes

The evergreen question, “What should I choose: Kubernetes or Docker?” is straightforward absurd, more like comparing apples with oranges. One is not an alternative for the other. On the contrary, Docker can run without Kubernetes and vice versa.

Here are the two main reasons behind it:

  • Making the infrastructure more robust and versatile: It will keep your application online, even when some nodes go offline, thereby providing high availability.
  • Making your application even more scalable: If the workload on your application increases, you spawn additional containers or add more Docker Hosts (nodes) to the Kubernetes cluster.

The Tabulated Difference Between Docker and Kubernetes

Although both are completely independent of each other and can be used separately, we have compiled a tabulated list of differences between these two to make you understand the excellent points with clarity.

The Similarities Between Docker and Kubernetes

These are some similarities that both Docker and Kubernetes have. Such as:

  • Both are open-source platforms.
  • Both of them have a large part of the Go language, thus making it very easy to be shipped as lightweight binary codes.
  • Both use YAML files (human-readable) to specify the application stacks and method of deployment.


Hopefully, now you might not be swayed away with jargon and carefully look at the application to determine whether Kubernetes and/or Docker might be a good fit.
