pack v0.7.0

This is the seventh 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. Note that pack is intended for local image builds, and thus requires a Docker daemon. The lifecycle should be used directly when building on cloud platforms.

Prerequisites

• The Docker daemon must be installed on your workstation or accessible over the network.

Install

If you're on macOS, you can use Homebrew:

$ brew tap buildpacks/tap
$ brew install pack

Otherwise:

1. Download the .tgz or .zip file for your platform
2. Extract the pack binary
3. (Optional) Add the directory containing pack to PATH, or copy pack to a directory like /usr/local/bin

Run

Run the command pack.

You should see the following output

Usage:
  pack [command]

Available Commands:
  build                 Generate app image from source code

Info

Builders created with this release of the pack CLI continue to contain lifecycle v0.5.0 by default. Builders created with the next upcoming lifecycle release (likely lifecycle v0.6.0), will not work with pack v0.5.0 or earlier, so please upgrade to pack v0.6.0 or later as soon as possible.

Features

• Adds short flags for pack build commands (#424)
• Removes pack run command (#451)
• Adds cloudfoundry/cnb:tiny to the list of suggested builders (#457)
• Cleans up the output to pack report (#433)

Fixes

• The pack create-builder command now properly handles builder configurations containing duplicate buildpacks (#459)
• pack create-builder properly validates lifecycle bundles for the presence of a descriptor (#434)
• Errors are now properly piped to STDERR (#436)

Known Issues

• Publishing to a private registry from Windows still fails in some cases (#109). We have fixed this upstream in Docker for Windows (docker/docker-credential-helpers#139), but Docker will need to ship a new version to fix this bug.
