What is Docker Kubernetes

Are you wondering what Docker Kubernetes is? Are you curious to know why integrating Docker with Kubernetes is crucial? If yes, then don’t miss out on this blog. We unlock the answer here. This blog explores what Docker Kubernetes is and the magic that Docker and Kubernetes make together. Let’s dive into the blog right away!

Rating: 4.8

Docker and Kubernetes are the two well-known container platforms. You can use Docker to build containers where you can deploy applications and their resources. Docker establishes an isolated environment for developing applications with enhanced security.

On the other side, you can use Kubernetes to orchestrate containers. Kubernetes automates load balancing and scaling of containers. The wonder is that when Docker and Kubernetes tools are used together, it creates a synergy that drives container management to the next level.

Let’s examine what Docker and Kubernetes do together!

What is Docker?

Docker is a robust open-source containerization platform. It’s a toolkit that developers use to build, deploy and manage containers. Docker is a cross-platform tool that allows running containers on any platform, such as Linux, Windows, or MacOS. Besides, Docker offers high-level portability. So, you can run Docker containers seamlessly in data centers, on-premises, and cloud environments.

The good thing about Docker is that it supports agile software development. It removes the complexities in CI/CD deployment processes. For instance, you can create and test Docker containerized applications on one platform and deploy them in another environment effortlessly.
Well! You have got some glimpses of Docker containers now. Let’s learn the fundamentals of Kubernetes in the next section.

What is Kubernetes?

Kubernetes is essentially a container orchestration platform. It is an open-source tool that automates managing, deploying, and scaling containerized applications. Know that the Kubernetes cluster is an architecture that contains multiple containers along with a master container.

The master container or control plane plays a pivotal role by distributing workloads for the remaining nodes - known as worker nodes. The good thing about Kubernetes is that it supports exceptional load balancing. Also, it can manage any traffic volume effectively.
Right now, you might have understood what Kubernetes is. What next?

What is Docker Kubernetes?

Let’s jump in to learn what Docker Kubernetes is. 
Although Docker and Kubernetes are two different technologies playing two different roles, they can be used together. This strategy simplifies container management and improves the efficiency of application development and deployment processes.
As you know, you can deploy applications in Docker containers. It creates an isolated environment for the applications, enhancing their security. When there is a sudden surge in workloads, you must manage Docker containers to balance the workloads. This is where Kubernetes steps into the spotlight. Kubernetes manages the dynamic workloads by deploying Docker containers across multiple IT environments.
Moreover, Kubernetes offers self-healing, automated rollouts and rollbacks, an appealing user interface, and more. Many companies use these features to manage containers effectively. Ultimately, Kubernetes helps to boost application development and deployment performance.
Okay! You are familiar with what Docker Kubernetes is now. What’s coming up next?

Join our Docker Kubernetes Training sessions led by experienced trainers, where you can delve into top Docker Kubernetes projects for hands-on practice and receive expert guidance to clarify your questions.

Why use Kubernetes over Docker?

Let’s check out the reasons why companies use Kubernetes over Docker.

  • Kubernetes manages Docker container resources using a single control plane or master container. The control plane single-handedly manages the load balancing, networking, and scaling of Docker containers that run on Kubernetes nodes.
  • Docker Kubernetes combo creates a robust IT environment that provides high availability to Docker applications.
  • Kubernetes comes with a built-in isolation mechanism that simplifies managing microservices-based Docker applications.
    Nice! Now, you have understood why Kubernetes is used over Docker. It’s time to turn towards understanding the benefits of Docker Kubernetes integration.

Use cases for Docker Kubernetes

Let’s discuss the use cases of Docker Kubernetes one by one.

  • Managing Microservices

Microservices are small, independent components that can be easily deployed and scaled. Docker containerizes the microservices, allowing Kubernetes to deploy and scale the microservices smoothly.

  • Accelerating the CI/CD process

You can integrate Docker images with CI/CD pipelines. Kubernetes streamlines CI/CD pipelines, reducing human intervention. It accelerates the deployment process.

  • Running containers on edge devices:

Docker can containerize applications on edge devices. Kubernetes can manage the applications, providing high availability. Not only that, this dynamic duo of Docker and Kubernetes improves consistency across edge devices.

  • Deploying containers in any cloud platform:

As Kubernetes and Docker are highly cloud agnostic, they can deploy, manage, and scale applications in any hybrid or cloud provider cloud environment.

Sure! Docker Kubernetes offers astonishing use cases to companies.

Benefits of Docker and Kubernetes

Let’s learn the benefits of Docker and Kubernetes integration in the following.

  • High Availability

Kubernetes automatically restarts the Docker containers that fail or malfunction. This is the reason why Docker containers are highly available.  

  • Enhanced Security

Kubernetes offers advanced security features such as network isolation, role-based access control,  and container image scanning to secure applications in Docker containers. Mainly, you can secure containerized applications from data breaches, unauthorized access, and more.

  • Excellent Portability

Kubernetes can move Docker containers from one environment to another seamlessly. Whether it is a hybrid environment, on-premises, or public cloud provider, Kubernetes easily moves containers from one location to another.

  • Improved Scalability

Kubernetes can upscale or downscale containerized applications effortlessly. So, any incoming traffic can be easily managed with the duo of Kubernetes and Docker.

  • Boosts Productivity

As Kubernetes and Docker automate the deployment and management of containerized applications, it eliminates human intervention and errors altogether. More to the point, time is saved, cost is reduced, and productivity is enhanced.

Super! You have exposure to Docker Kubernetes' benefits. Similarly, Docker Kubernetes offers companies plenty of use cases. The following section discusses them in greater detail.


  • Docker is a tool with which you can create containerized applications.
  • Kubernetes is a tool that helps to orchestrate Docker containers.
  • When Docker and Kubernetes are combined, they drive powerful results.
  • Docker Kubernetes integration simplifies complexity in balancing workloads.
  • This integration provides excellent capabilities in managing and scaling applications and scaling applications.
