Why would anyone build with this?

REASON 1

Package a Python project with all its dependencies into a portable Docker image without installing Docker.

REASON 2

Speed up repeated image builds using smarter layer caching than standard Docker builds.

REASON 3

Put a heavy shared library like Intel MKL in its own layer so it's only downloaded once across multiple images.

REASON 4

Programmatically download, modify, and re-save Docker images using the Python library API.

No Docker installation needed, but requires understanding Conda package specs and base image selection.

Yoink these prompts

Prompt 1

Show me the command-line syntax for building a Docker image from a base image and a list of Conda packages.

Prompt 2

Explain how Conda Docker builds image layers directly without needing Docker installed.

Prompt 3

Walk me through using the Python API to download an image from Docker Hub, add files, and save a modified version.

Prompt 4

How does Conda Docker cache packages to make rebuilds faster than a normal Docker build?

Prompt 5

Set up a build that puts Intel MKL in its own shared layer across multiple related images.
