What is Kubernetes?

It is an application orchestrator for containerised cloud native microservices app.

• Orchestrator: a system that deploys and manages application with auto scaling, self-healing features
• Containerised app: An app that runs in containers (a progression from physical server, virtual machines).
• Microservices: A system of services, each with a single function and responsibility.

Docker and Kubernetes?

They complement each other.

Most of the time,

1. Write your code in your favourite languages
2. Use Docker to package it, test it, and ship container.
3. The final steps of deploying and running it are handled by Kubernetes.

Of course, Kubernetes work with other container technologies as well.

Kubernetes and Docker Swarm are similar
