pack v0.18.1-rc2

This is a beta pre-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

Linux

Command

(curl -sSL "https://github.com/buildpacks/pack/releases/download/v0.18.1-rc2/pack-v0.18.1-rc2-linux.tgz" | sudo tar -C /usr/local/bin/ --no-same-owner -xzv pack)

Manually

Download the .tgz or .zip file for your platform
Extract the pack binary
(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:
