lifecycle v0.17.0-rc.2

lifecycle v0.17.0-rc.2

Welcome to v0.17.0-rc.2, 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-rc.2.

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)
• (Experimental) When using platform API 0.12 or greater, the lifecycle supports export to OCI layout format on disk (#969 by @jjbustamante)
• When selecting a run image, the analyzer and rebaser verify read access (#1024 by @pbusko, @c0d1ngm0nk3y, @modulo11, and @kulhadia)
• The analyzer validates the cache image and previous image are valid (#1060 by @matthewrobertson)
• When using platform API 0.12 or greater, the exporter includes history in the application image (#1099 by @natalieparellano)
• When using platform API 0.12 or greater, the rebaser will fail if the provided run image is not found in the io.buildpacks.lifecycle.metadata label, unless --force is passed; if --force is passed, it overrides the existing run image and run image mirrors information (#1104, #1132 by @natalieparellano)
• The lifecycle when checking read/write access to images will surface the error if there are no images to fallback to (#1133 by @natalieparellano)
• Updates go to version 1.20.5 (#1130 by @natalieparellano)

Chores

• buildpack.DecodeLayerMetadataFile() accepts a logger instead of returning a message (#1038 by @anushkamittal20)
• Add layer metadata test as living doc (#1019 by @AidanDelaney)
• Make a single constructor for lifecycle inputs (#1009 by @natalieparellano)
