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.
