What’s the difference between Docker and Kubernetes?
Submitted by cloud_newbie
I've been hearing a lot about Docker and Kubernetes, but I'm confused about their roles in development. Do I need to use both? What are the key differences and when should I choose one over the other?

Docker is for containerizing applications, while Kubernetes is for orchestrating and managing those containers at scale. Use Docker to create your containers and Kubernetes when you need to manage multiple containers across servers.

Think of it this way: Docker is the tool to package your app, and Kubernetes is the tool to deploy and scale it across a cluster. They often work together.

If you're just getting started, Docker is simpler to learn and use. Kubernetes comes into play when you're managing a large-scale, distributed system with many microservices.

  • Respect the Holy Semicolon : Whether you love it or hate it, debates about using semicolons must remain civil. Violators will face an infinite loop of syntax error memes.
  • No Framework Shaming : Every framework has its place (even jQuery). Criticizing someone’s choice of tools will result in mandatory TypeScript adoption.
  • Explain Like I’m a Database : All questions must include enough context to avoid "SELECT * FROM confusion WHERE clarity IS NULL."
  • Ask First, Build Later : Before seeking advice, ensure you're not solving a problem no one has (a.k.a., premature optimization).
  • Memes Are Sacred : Memes are welcome but must be related to coding or computer science. Off-topic memes will be replaced with "Hello World" jokes.
  • Framework of the Month Club : Hype about frameworks is restricted to one framework per month. This month's favorite? Vue! Next month? Surprise!
  • Documentation Before Deployment : If you’re asking about deployment without reading the docs, expect replies with RTFM gifs only.
