pack v0.27.0

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

Prerequisites

• A container runtime such as Docker or podman must be available to execute builds.

Install

For instructions on installing pack, see our installation docs.

Run

Run the command pack.

You should see the following output

Info

Builders created with this release of the pack CLI contain lifecycle v0.14.1 by default.

Changelog

Features

• Update error when bp order group is malformed for meta-buildpacks (#1437 by @imnitishng)
• When pack is run with --verbose, it should not print registry creds (#1433 by @natalieparellano)
• When platform api >= 0.9, analyzer accepts -skip-layers and -launch-cache (#1417 by @natalieparellano)

Known Issues

• Running pack build with a builder using lifecycle 0.14.0 yields an error "ERROR: failed to create launch cache".
  • Cause: buildpacks/lifecycle#847
  • Resolutions:
    • Option 1: Use a builder with lifecycle >= 0.14.1.
      pack builder inspect <builder-image> can be used to inspect a builder image.
    • Option 2: Use --lifecycle-image=buildpacksio/lifecycle:0.14.1 --trust-builder=false flags with pack build.
      These flags would make pack use the patched version of the lifecycle for the analyze, restore and export phases.
