What is more imperative when it comes to containers? Is it the size or portability? I can say both are equally important beyond a shadow of a doubt. I strongly believe Docker containers are best for deployment. When thousands of firm use different containers to run applications, why don’t we try experiencing the benefits of Docker and Kubernetes together to manage applications which would bring out the optimum productivity? Here we’re presenting the few surprising facts that you must get to know when Docker and Kubernetes are used together.
Now let me help you to catch a glimpse of what is Docker and Kubernetes in short-term. Docker is a tool or you can call it as a software program where you can build, manage and secure your apps. You can run Docker container on a single server, the container works like a virtual operating system to run applications. By using a Docker container, you can acquire numerous benefits.
Benefits of Docker:
- Docker yields the unsurpassed standardization and productivity
- Acquire the benefit of rapid deployment using Docker containers.
- Docker containers are Multi-cloud platforms
- Setting up and installation is even more simple and agile with Docker.
Despite the advantages we have in Docker containers, Kubernetes doing an excellent job in automated deployment. As we all know, Kubernetes is an open source orchestrator that is used to deploy, scale and manage containerized applications. A good thing about Kubernetes is that, it is developed by Google.
It is considered as a platform that has been designed to completely manage containerized applications. The ultimate feature of Kubernetes is that it can manage containers across multiple nodes as simple as managing containers on a single server.
Features of Kubernetes:
- Automated Scheduling: Kubernetes provides advanced scheduler which would be beneficial to launch container on cluster nodes.
- Self-healing competency: Kubernetes has a remarkable feature which others don’t. It has the capability to reschedule, replace and restart the containers that are already expired.
- Automatic Rollouts and Rollbacks: Kubernetes includes rollout and rollback feature that helps to run containerized applications.
- Horizontal Scaling: It has the capability to scale up and scale down based on the requirement.
- Service discovery and load balancing: In the midst of billions and trillions of IP addresses used worldwide, Kubernetes uses the unique one to recognize them across the cluster and the DNS name to containers is also unique.
Docker Containers With Kubernetes:
Docker provides an open standard for packaging and distributing containerized applications. But, where’re these multiple containers are scheduled and coordinated? Here you go with Kubernetes. Kubernetes and Docker when combined together provide best solutions by effectively organizing containerized applications.
You may ask why we should go for Kubernetes when we have Docker Swarm. I can tell you that Kubernetes and Docker Swarm both are used to deploy containers inside a cluster. Both have similar functionalities but they both differ in the way they’re operated. Moreover, One of the major advantage that we have with Kubernetes is that it is an open source orchestrator and it greatly works with any OS.

Using Docker And Kubernetes together:
Docker container will help you to segregate and pack your software whereas the Kubernetes are responsible for deployment. Kubernetes on the other hand, orchestrate your containers. Indeed, Kubernetes is a container orchestration system for Docker containers which has widely applicable effects than Docker Swarm. Similarly, it is known for coordinating clusters of nodes to scale methodically.
Kubernetes use pods as the scheduling units in the Kubernetes environment. The pods are disseminated nodes in order to attain high availability. We can easily run a Docker build when it’s on Kubernetes cluster. Kubernetes helps to coordinate the scheduling and execution of Docker containers on kubelets by integrating with Docker engine. Here the Docker engine is responsible to run and manage the actual container image that is built by running ‘Docker build’.
Kubernetes and Docker aren’t equivalent since they both seemed to be operated in different technologies. However, they are ought to deliver the optimum results when they are combined together. Both Docker and Kubernetes facilitate the management and enhance deployment of containers in a distributed architecture.
Leading concepts such as service-discovery, load balancing and network policies are systematized by Kubernetes. When you get to know the combined benefit of Docker and Kubernetes, you can begin to run and manage your applications at large scale.

Well, I could write about the docker and Kubernetes even for a whole day but i don’t want to load you with excess information so i jumped straight to the point and channeled only the ideal features that you must know about this deadly combination of Docker and Kubernetes. Wrote it with a spark to help you guys with the right and clear information. Finally, am all done here and leaving it to your eye sight with a profound satisfaction.
