Vagrant で DevStack を一発起動

Last updated at Posted at 2013-10-26

目的

DevStack 環境を Vagrant 経由で VirtualBox 上の Ubuntu 12.04(Precise) に、vagrant up コマンドでインストールする。

おことわり

OpenStack 自体の使用方法については記載しません。

必要なもの

  • VirtualBox で 4GB 程度の 64bit 仮想マシンが起動できる環境。Linux でも Mac でも OK。
  • Vagrant
  • VirtualBox で起動した仮想マシンが、直接外部のインターネットと接続できるLAN環境。例えば仮想マシンがUbuntuなら、sudo apt-get update の実行が普通にできること。http接続にプロキシが必要な環境は、今回考慮していません。

準備

仮想マシンの登録

Vagrantbox.es から base box を取得して登録しておきます。

$ vagrant box add precise64 http://files.vagrantup.com/precise64.box
Downloading or copying the box...
Extracting box...te: 5406k/s, Estimated time remaining: 0:00:01)
Successfully added box 'precise64' with provider 'virtualbox'!
$ vagrant box list
precise64 (virtualbox)
$

Vagrantfile の編集

適当なディレクトリで vagrant init precise64 を実行する。

$ mkdir devstack
$ cd devstack/
$ vagrant init precise64
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
`vagrantup.com` for more information on using Vagrant.
$

Vagrantfile を以下のように編集します。

Vagrantfile
# -*- coding: utf-8 -*-
# -*- mode: ruby -*-
# vi: set ft=ruby :

# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "precise64"           # 使用する box 名
  config.vm.define :vm00 do |conf|
    conf.vm.hostname = "vm00"           # 仮想マシンホスト名
    conf.vm.network :public_network,    # 仮想マシンのIPアドレス
                    ip: "192.168.1.220" # 使用しているLAN環境に合わせる
    conf.vm.provider "virtualbox" do |v|
      v.customize ["modifyvm", :id,
                   "--memory", "3072",  # 2048(MB)は必須。4096(MB)以上を推奨
                   "--nicpromisc2", "allow-all"] # promiscuous モード有効
      # v.gui = true # VirtualBox の GUI が必要なら true に
    end

    conf.vm.provision :chef_solo do |c|
      c.add_recipe "devstack"           # 使用するレシピ名
    end
  end
end

cookbooks の作成

Vagrantfile のあるディレクトリに、以下のように cookbooks ディレクトリを作成する。

$ ls
Vagrantfile
$ mkdir -p cookbooks/devstack/recipes
$ mkdir -p cookbooks/devstack/files/default
$ find Vagrantfile cookbooks
Vagrantfile
cookbooks
cookbooks/devstack
cookbooks/devstack/recipes
cookbooks/devstack/files
cookbooks/devstack/files/default

レシピと必要なファイルを用意する。

※注意： vagrant と ALL=(ALL:ALL) の間はタブにしておいて下さい。

上記の以下の部分を見ればわかるように、それなりに時間がかかります。

DevStack の stack.sh の実行状況をリアルタイムで知りたい場合は、 vagrant ssh で
作成した仮想マシンにログインして、tail -f ~/bootlog/stack.sh.log を実行してみてください。

エラーが発生しなければ、以下のようなログが最後に現れます。

Horizon is now available at http://192.168.1.220/
Keystone is serving at http://192.168.1.220:5000/v2.0/
Examples on using novaclient command line is in exercise.sh
The default users are: admin and demo
The password: openstack
This is your host ip: 192.168.1.220

※stack.sh 内の処理によっては、異なるメッセージで終了する場合もありえます。

例
2013-10-26 07:13:50 stack.sh completed in 164 seconds.

エラーでなければ気にしないでください。

注意点

  • DevStack や OpenStack は日々更新されるので、もしかしたらこの環境が動作しない日もあるかもしれません。
  • 使用している仮想マシンの box の環境自体が更新されていないと、期待した動作が得られない場合があります。DevStack を ~/devstack/unstack.sh で一度停止させたあと、 sudo apt-get update && sudo apt-get -y dist-upgrade で環境を更新し、改めて ~/devstack/stack.sh を実行してみて下さい。
  • VirtualBox が動作するホストで、アンチウィルスソフトの Web アクセス保護機能のようなものが動作していると、DevStack が途中で失敗する場合があります。
