Vagrant : インストール2023/06/20

VirtualBox 等の仮想化ソフトウェアのラッパーツール Vagrant をインストールします。
主要な仮想化ソフトウェアには概ね対応していますが、当例では Libvirt インストール済みを前提とします。
[1] Vagrant をインストールしておきます。
apt -y install vagrant-libvirt
# 一般ユーザーで利用する場合は [libvirt] グループに追加

usermod -aG libvirt debian
[2] Vagrant の基本操作です。任意の一般ユーザーで利用可能です。
# 仮想マシンイメージをダウンロードして追加
# ダウンロード可能な Box は公式サイト参照
# ⇒

vagrant box add generic/debian11 --provider libvirt

==> box: Loading metadata for box 'generic/debian11'
    box: URL:

==> box: Successfully added box 'generic/debian11' (v4.2.16) for 'libvirt'!

# 初期化 (カレントパスに Vagrantfile が作成される)

vagrant init generic/debian11

A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`` for more information on using Vagrant.
