Docker vs Kubernetes

Docker

Description: Docker is an open platform for developing, shipping, and running applications. It allows developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.

Type: software

Pricing: Free

Kubernetes

Description: Kubernetes is an open-source container orchestration system for automating deployment, scaling, and management of containerized applications. It groups containers into logical units for easy management and discovery.

Type: software

Pricing: Open Source

Docker Features

• Containerization - Allows packaging application code with dependencies into standardized units
• Portability - Containers can run on any OS using Docker engine
• Lightweight - Containers share the host OS kernel and do not require a full OS
• Isolation - Each container runs in isolation from others on the host
• Scalability - Easily scale up or down by adding or removing containers
• Versioning - Rollback to previous versions of containers easily
• Sharing - Share containers through registries like Docker Hub

Kubernetes Features

• Automatic binpacking
• Self-healing
• Horizontal scaling
• Service discovery and load balancing
• Automated rollouts and rollbacks
• Secret and configuration management
• Storage orchestration
• Batch execution
