Docker

Containers for AI services. The default packaging format for production AI.

What is Docker?

The container runtime that made microservices viable. Docker packages your code + its dependencies + its runtime into an image that runs identically on any machine. In the bootcamp it underpins everything from week 9 onwards — every capstone ships as a Docker image.

Key Features

  • One Dockerfile = identical runtime everywhere
  • Multi-stage builds keep production images small
  • Docker Compose for multi-service local dev
  • BuildKit cache mounts for fast Python/Node builds
  • Docker Hub or any OCI registry for image distribution
  • First-class GPU support for ML workloads

FAQ

Why ship AI services as Docker images? +

Because the dependency tree of an AI service (CUDA versions, Python wheel pins, system libraries) is brittle. Pin everything in a Dockerfile and you eliminate "works on my machine" entirely — and Kubernetes wants images, not source.

Docker vs containerd vs Podman? +

Docker Engine is the dev experience and tooling layer. containerd is the runtime underneath (used directly by Kubernetes). Podman is a daemonless alternative that's rootless by default — useful in restricted environments. For learning, Docker. For prod, your platform decides.
