Dockerfile不要でコンテナイメージが作成できるBuildpacksを使ってコンテナイメージを作ってみました。
Buildpacksとは
公式サイトより
Cloud Native Buildpacks transform your application source code into images that can run on any cloud. In this session you'll learn the basics of using buildpacks, why they make a great choice over the alternatives, and what new features the project has to offer. Cloud Native Buildpacks embrace modern container standards, such as the OCI image format. They take advantage of the latest capabilities of these standards, such as cross-repository blob mounting and image layer "rebasing" on Docker API v2 registries.
Cloud Native Buildpack は、アプリケーションのソースコードを、あらゆるクラウド上で実行可能なイメージに変換します。このセッションでは、ビルドパックの基本的な使い方、ビルドパックが他の選択肢より優れている理由、そしてプロジェクトが提供する新しい機能について学びます。Cloud Native Buildpack は、OCI イメージ形式のような最新のコンテナ標準を採用しています。これらの標準の最新機能、例えばリポジトリ間のBLOBマウントやDocker API v2レジストリ上でのイメージ層の「リベース」などを利用します。
Multipass環境の準備
Multipassを使用してVMを用意します。
MultipassのDocker入りVMを作成
multipass launch docker --name docker
Multipass起動
multipass shell docker
