Distinction between Kubernetes vs Docker


Kubernetes vs Docker
‘Kubernetes’ word stylized as floating cloud. Concepts: Cloud Technology, Public clouds, Devops, Site Reliability Engineering, Software development.

Introduction

The Kubernetes vs Docker is a common debate in the containerization world. Although most people think Kubernetes and Docker are the same; the two technologies are not exchangeable—you cannot choose one over the other. They are essentially discrete technologies. This article explains the difference between Kubernetes vs Docker from scratch and will help you to answer each of the important questions.

What is Kubernetes?

Kubernetes is a container management software developed by Google. Thai open-source software helps you to manage a containerized application in various types of physical, virtual, and cloud environments. This is a highly flexible container tool to deliver complex applications. 

What is Docker?

Docker is also an open-source containerization technology to gain widespread popularity in the cloud. This helps in automating the deployment process and allows multiple OS on the same host. 

Features of Kubernetes

Some of the features of Kubernetes are listed below:

  • Automated scheduling
  • Self-Healing capabilities
  • Automated rollouts & rollback
  • Horizontal Scaling & Load Balancing
  • Provides a higher density of resource utilization
  • Offers enterprise-ready features
  • Application-centric management
  • Auto-scalable infrastructure
  • Deploy and update software at scale

Features of Docker

Some of the features of Kubernetes are listed below:

  • Easy Modeling
  • Version control
  • Placement/Affinity
  • Application Agility
  • Developer Productivity
  • Operational Efficiencies

The Relationship Between Kubernetes and Docker

We all know Kubernetes and docker are separate technologies- yet they complement each other and work together. 

Docker is at the core of containerization technology—it allows you to create and deploy application containers. Whereas, Kubernetes offers a useful orchestration platform for your Docker containers.

Combination of both Kubernetes with Docker results in the following benefits:

  • It enhances the robustness of your infrastructure. 
  • It improves the scalability of your applications. 

Advantages of Kubernetes

Some of the advantages of Kubernetes are: 

  • Easy organizational service
  • Largest community among container orchestration tools.
  • Offers a variety of storage options.
  • Adheres to the principles of immutable infrastructure.

Advantages of Docker

Some of the advantages of Docker are: 

  • Offers an easier initial set-up
  • Integrates with existing Docker tools
  • Allows you to describe your application lifecycle in detail
  • Documentation provides every bit of information.
  • Provides simple and fast configuration to boost your business
  • Ensures that application is isolated

Disadvantages of Kubernetes

Some of the disadvantages of Kubernetes are: 

  • Migrating to stateless
  • Limited functionality
  • Highly complex Installation process
  • Not compatible with existing Docker CLI
  • Complicated manual cluster deployment.

Disadvantages of Docker

Some of the disadvantages of Docker are: 

  • Doesn’t provide a storage option
  • Has poor monitoring option.
  • No automatic rescheduling of inactive Nodes
  • Complicated automatic horizontal scaling set up
  • All the actions have to be performed in CLI.
  • No support of health-checks

Difference between Kubernetes vs Docker

DOCKER KUBERNETES
Docker is the tool to deploy containers. Kubernetes is a Container Orchestration tool.
Docker runs on a single node. Kubernetes run across a cluster
In Docker different nodes can’t communicate with each other. In Kubernetes, different nodes can communicate with each other.
Docker Swarm is used to managing containers. Kubernetes is widely used in industries.
Docker automatic scaling is not possible. Kubernetes takes care of scaling.
Developed by Docker Inc Developed by Google
No Autoscaling Auto-scaling
Setting up the cluster is challenging. Setting up the cluster is simple.
Installation is Easy & fast Installation is Complicated & time-consuming.
Allows you to use a 3rd party tool like ELK. It offers an in-built tool for logging and monitoring.
Does auto load-balancing Manually configure your load balancing settings
Tolerance ratio: High fault tolerance Tolerance ratio: Low fault tolerance
Supports 2000 > nodes Supports up to 5000 nodes
Limited to 95000 container Limited to 300000 containers
The public cloud service provider is Azure only. The public cloud service provider is Google, Azure, and AWS.
Less extensive and customizable More comprehensive and highly customizable
An active user base that regularly updates the software. Offers strong support from open source communities and big companies like Google, Amazon, Microsoft, and IBM
Speed is considered for the strong cluster states. Offers container deployment and scaling, even in large clusters without considering the speed.

Conclusion

Kubernetes and Docker are both works on separate principles but they complement each other and give an all-around incorporated stage to orchestration, deployment, and container management at scale. In fact, it’s never Kubernetes vs Docker; it is Kubernetes and Docker.
