pack v0.20.0

pack v0.20.0

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. 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

For instructions on installing pack, see our installation docs.

Run

Run the command pack.

You should see the following output
