Docker Versus Kubernetes – All You Need To Know

Docker & Kubernetes

Docker and Kubernetes are the container orchestration solutions where in Kubernetes is a container orchestrator and Docker is a containerization platform. Docker and Kubernetes both help to reinvent the way applications are built and deployed.

Containers are transforming the modern application infrastructure everywhere. The Containers virtualizes an operating system (OS) in such a way that multiple workloads can run on a single OS. These are very light weighed thus takes only seconds to start. Containers work on a physical server and a common OS that result in reduced overhead management. These also solve the issue of portability by allowing us to separate code from its underlying infrastructure on which it is running. The speed, agility, and portability of container technology make it exceptionally useful in Software Application Development Services.


Docker was introduced in 2013 to accelerate and simplify container app development. It gives developers the freedom to select tools, application stacks and deployment environments of their choice to innovate the applications. It is effective in building and sharing containerized applications from desktops to the cloud. It makes containers a user-friendly and developer-friendly commodity. The enterprises have adopted Docker widely in their AWS Cloud Computing Services.

How to build a Docker container?

A portable and static Docker image has to be built using the Docker files and run on the Docker Engine to create a container. A Docker file consists of everything that is needed to run the image including the OS network specifications and file locations. The service known as Docker Hub can also be used if you don’t want to create containers from scratch; it functions to store and share the images.

The need for Orchestration Systems!

The role of isolating, packaging and distribution of the container apps are done by the Dockers. Soon after the app distribution, the Orchestration Systems comes into play to coordinate, schedule, upgrade and monitor the health of Application Maintenance. Two most popular Orchestration Systems are Kubernetes and Docker Swarm. These systems make a cluster of machines behave like one big machine which is necessary for a large-scale environment.


Kubernetes is a container orchestrator to manage the containerized application in various physical, virtual, and cloud environments. It is a highly flexible container tool originally developed by Google to deliver complex applications. Now, it is maintained by Cloud Native Computing Foundation (CNCF). Kubernetes can automate the deployment, scheduling and scaling of containerized applications. It has the advantage of leveraging Google’s years of expertise in container management and also supports many containerization tools including Docker. It requires a certain amount of technical experience to handle the process well.

You need both Docker and Kubernetes for the containerization of apps in DevOps Services. After deployment of the container app, Kubernetes constantly monitors the state of deployment. And in case the Docker container goes down, Kubernetes will automatically spin up a new one. There won’t be a need to go manually check each server where the container failed to start it up again. Combining both the technologies to run and orchestrate apps results delivering in a quick, consistent and predictable manner. This ultimately increases the confidence and productivity of developers. Our expert developers offer extensive support for all types of DevOps services at Digital Mesh. We have successfully provided Kubernetes powered applications to our global clients.
