lifecycle v0.17.0-pre.1

lifecycle v0.17.0-pre.1

Welcome to v0.17.0-pre.1, a beta pre-release of the Cloud Native Buildpacks Lifecycle.

Prerequisites

The lifecycle runs as a normal user in a series of unprivileged 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 tekton.

Lifecycle Image

An OCI image containing the lifecycle binaries is available at buildpacksio/lifecycle:0.17.0-pre.1.

Features

• When using platform API 0.12 or greater, the lifecycle validates “targets” instead of stacks (#994, #1030, #1050, #1053, #1064 by @joe-kimmel-vmw, #1056 by @jabrown85, #1005 by @natalieparellano)
• (Experimental) When using platform API 0.12 or greater, the lifecycle supports run image extension with Dockerfiles, in addition to run image switching (#1011, #1014, #1022, #1055 by @natalieparellano, #1032 by @jabrown85)
  • A demo of the feature can be found here: buildpacks/docs#581
