lifecycle v0.2.0

This is the second beta release of the Cloud Native Buildpack Lifecycle. This implementation should be relatively stable and reliable, but breaking changes in the underlying specification may be implemented without notice.

Prerequisites

The lifecycle runs as a normal user in a series of unprivileged Linux containers. To export images and cache image layers, it requires access to a Docker daemon or Docker registry.

Install

Extract the .tgz file and copy the lifecycle binaries into a build stack base image. The build image can then be orchestrated by a platform implementation such as the pack CLI or knative.
