Usage

Build

Either:

• analyzer - Reads metadata from the previous image and ensures registry access.
• detector - Chooses buildpacks (via /bin/detect) and produces a build plan.
• restorer - Restores layer metadata from the previous image and from the cache, and restores cached layers.
• builder - Executes buildpacks (via /bin/build).
• exporter - Creates an image and caches layers.

Or:

• creator - Runs the five phases listed above in order.

Run

• launcher - Invokes a chosen process.

Rebase

• rebaser - Creates an image from a previous image with updated base layers.
