The Difference Between Docker and Kubernetes

Updated: May 30, 2019

Containerization allows applications to run on any machine- anytime, anywhere so long as they are compatible. By virtualizing your OS, you are able to lessen its dependencies. This method makes every application kernel-based and ultimately, scratching out the need for an entire VM to run programs.

Containers house an application, its dependencies and specific library. They isolate data and create an environment that familiarizes itself with its repetitive processes- therefore, decreasing its exposure to threats and irrelevant data.

Here we talk about the two main containerization platforms- Docker and Kubernetes. So how can you effectively utilise the different platforms? Moreover, what sets them apart and how can you maximise the service?


Docker allows you to run, create and organize containers. The container will only run with this software. Also, while you may have a many containers, you are only able to run one container at a time.

The platform is the tool that enables containers to run on your computer or device- it is a must-have for running applications on these containers.


If Docker is the software to run containers on, Kubernetes is the platform in which you can control and manage these containers. It is a conductor that triggers other containers if need be. The orchestration solution has the ability to run containers simultaneously and in relation to one another.

The ability to command containers to run on demand is thanks to the container orchestration solution that is intrinsic to Kubernetes.

The Difference between Docker and Kubernetes?

Aside from the reality that Docker can exist independently of Kubernetes but the latter would need Docker to function- its fundamental use are nowhere near the same.

Docker runs containers while Kubernetes was designed to control how these containers interact with each other.

The key is in knowing your organisation’s needs. If you only need to protect and determine data that would go into specific applications or containers, then using only Docker may already be sufficient.

On the other hand, running multiple containers at once with high traffic and demand would need a sophisticated container management tool. That means Kubernetes is the man for the job.

Think of it as Play Station and Steam, with the containers being the games. You can run a game on a Play Station- however, you would need a computer for Steam to be loaded on to play the games. Despite that, Kubernetes, or Steam, also looks after your containers. It protects them and makes sure that they are able to run repetitively without fail.

While Docker limits your container use, Kubernetes lets you run multiple containers at once while protecting them and keeping them up to date.
