Hashicorpの新プロダクト「Otto」を試してみた

2015/09/29

全国1000万人の大トロ好きのみなさんこんにちは。

Hashicorpから新たにOttoと呼ばれるプロダクトがリリースされました。

OttoはVagrantの後継となるもので、開発からデプロイまで一気通貫で行うことができるソリューションでマイクロサービスでの活用も考慮されて作られているということで早速試してみました。 軽く触った印象としては、Vagrant、Packer、Terraform、ConsulなどいままでHashicorpが提供してきたツールを組み合わせて一気通貫で操作できるようになった、と考えるとわかりやすそうです。

インストール

https://ottoproject.io/downloads.html にアクセスして自分の環境にあったバイナリをダウンロードして展開します。展開したら実行できるようにPATHに追加します。

僕の場合はアーカイブを~/tools/otto/に配置したので以下のようにします。設定が終わったら環境変数を読み込み直してください。

export PATH=PATH:~/tools/otto/

インストールが終わったら、ottoコマンドを実行します。以下のように表示されればインストールは正常に完了しています。

usage: otto [--version] [--help] <command> [<args>]

Available commands are:
    build      Build the deployable artifact for the app
    compile    Prepares your project for being run.
    deploy     Deploy the application
    dev        Start and manage a development environment
    infra      Builds the infrastructure for the Appfile
    status     Status of the stages of this application
    version    Prints the Otto version

開発環境を作ってみる

まずは開発環境を作ってみます。サンプルが用意されているのでその通りやってみます。

以下のようにしてサンプルを取得して、当該ディレクトリに移動します。

git clone https://github.com/hashicorp/otto-getting-started.git
cd otto-getting-started

以下のファイルがあるはずです。単純なSinatraを使ったRubyアプリケーションです。

.
├── ./Gemfile
├── ./Gemfile.lock
├── ./README.md
├── ./app.rb
├── ./config.ru
└── ./views
    ├── ./views/index.erb
    └── ./views/name.erb

ここで、以下を実行します。これはこのアプリケーションを動作させるのに必要な依存関係を調査し設定を行うものです。

otto compile

以下のように表示されればOKです。ottoではAppfileというファイルに環境の設定を記述することもできますが、今回はアプリディレクトリにAppfileが存在しないので、otto自身がプロジェクトの種類を検出しています。

==> Loading Appfile...
==> No Appfile found! Detecting project information...
    No Appfile was found. If there is no Appfile, Otto will do its best
    to detect the type of application this is and set reasonable defaults.
    This is a good way to get started with Otto, but over time we recommend
    writing a real Appfile since this will allow more complex customizations,
    the ability to reference dependencies, versioning, and more.
==> Fetching all Appfile dependencies...
==> Compiling...
    Application:    otto-getting-started (ruby)
    Project:        otto-getting-started
    Infrastructure: aws (simple)

    Compiling infra...
    Compiling foundation: consul
==> Compiling main application...
==> Compilation success!
    This means that Otto is now ready to start a development environment,
    deploy this application, build the supporting infastructure, and
    more. See the help for more information.

    Supporting files to enable Otto to manage your application from
    development to deployment have been placed in the output directory.
    These files can be manually inspected to determine what Otto will do.

これで準備が出来たので開発環境をビルドします。

otto dev

以下のようなログが出力されます。順番に見れば分かる通り、Vagrantを使って仮想環境を用意しています。

==> Creating local development environment with Vagrant if it doesn't exist...
    Raw Vagrant output will begin streaming in below. Otto does
    not create this output. It is mirrored directly from Vagrant
    while the development environment is being created.

==> Development environment successfully created!
    IP address: 172.16.1.250

    A development environment has been created for writing a generic
    Ruby-based app.

    Ruby is pre-installed. To work on your project, edit files locally on your
    own machine. The file changes will be synced to the development environment.

    When you're ready to build your project, run 'otto dev ssh' to enter
    the development environment. You'll be placed directly into the working
    directory where you can run 'bundle' and 'ruby' as you normally would.

    You can access any running web application using the IP above.

早速この仮想マシンにログインします。内部的にはvagrant ssh devと同じですね。

otto dev ssh

アプリケーションを起動します。

bundle && rackup --host 0.0.0.0

開発環境のアプリケーションは9292ポートで起動するので、端末のブラウザを使って、http://[先ほどの起動時のログで出力されたIPアドレス]:9292/にアクセスしましょう。以下のような画面が出れば成功です！

アプリケーションを開発する際は、ローカル端末側のディレクトリのファイルを編集すれば、そのディレクトリがVagrantと共有されているのですぐに反映されます。例えば、views/index.erbを編集してブラウザをリロードすればOKです。

本番環境の構築

本番環境にはAWSをはじめとしてさまざまな環境を利用することができます。なお環境の構築には内部的にTerraformが使われています。

まず、以下を実行します。対話的に設定を行うことになります。

otto infra

最初にいくつか聞かれますので適宜設定します。Terraformがインストールされていない場合はローカル端末にインストールも自動で行われます。

==> Detecting infrastructure credentials for: otto-getting-started (aws)
    Existing infrastructure credentials were not found! Otto will
    now ask you for infrastructure credentials. These will be encrypted
    and saved on disk so this doesn't need to be repeated.

    IMPORTANT: If you're re-entering new credentials, make sure the
    credentials are for the same account, otherwise you may lose
    access to your existing infrastructure Otto set up.

SSH Public Key Path
  Path to an SSH public key that will be granted access to EC2 instances

  Default: ~/.ssh/id_rsa.pub
  Enter a value: 

Password for Encrypting Credentials
  This password will be used to encrypt and save the credentials so they
  don't need to be repeated multiple times.

  Enter a value: 
==> Building main infrastructure...
Would you like Otto to install Terraform?
  Otto requires terraform to be installed, but it couldn't be found on your
  system. Otto can install the latest version of terraform for you. Otto will
  install this into its own private data directory so it doesn't conflict
  with anything else on your system. Would you like Otto to install terraform
  for you? Alternatively, you may install this on your own.

  If you answer yes, Otto will install terraform version 0.6.3.

  Please enter 'yes' to continue. Any other value will exit.

  Enter a value: yes

以降、どんどん処理が進みます。

• まずTerraformをインストールする。それを使って以下のようなことを実行します。
• us-east-1のリージョンに新たなVPCを10.0.0.0/16のCIDRブロックで作成
• その中に、10.0.2.0/24のCIDRでパブリックサブネットを作成
• 外部からの22番ポートへの接続を許可するセキュリティグループの作成
• このサブネットの中にインスタンスを作成

==> Downloading terraform v0.6.3...
    URL: https://dl.bintray.com/mitchellh/terraform/terraform_0.6.3_darwin_amd64.zip

    71.8 MB/71.8 MB

==> terraform installed successfully!
==> Executing Terraform to manage infrastructure...
    Raw Terraform output will begin streaming in below. Otto
    does not create this output. It is mirrored directly from
    Terraform while the infrastructure is being created.

    Terraform may ask for input. For infrastructure provider
    credentials, be sure to enter the same credentials
    consistently within the same Otto environment.

次にアプリケーションをビルドしましょう。ここではAWSのAMI(Amazon Machine Image)を作ります。内部的にPackerを利用しているのでインストールされていない場合は自動でインストールされます。

otto build

を実行します。以下のようなログが表示され、AMIが作成されたのがわかります。すなわちAWSへのデプロイは毎回AMIを作りなおして、そのAMIからインスタンスを起動して入れ替えるというアプローチです(ということは状態をどう管理するかを考えないといけないことになります。将来的にはこの部分をコンテナ対応することを考えているという記載が公式サイトにあります)。

==> Detecting infrastructure credentials for: otto-getting-started (aws)
    Cached and encrypted infrastructure credentials found.
    Otto will now ask you for the password to decrypt these
    credentials.

Encrypted Credentials Password
  Infrastructure credentials are required for this operation. Otto found
  saved credentials that are password protected. Please enter the password
  to decrypt these credentials. You may also just hit <enter> and leave
  the password blank to force Otto to ask for the credentials again.

  Enter a value: 
Would you like Otto to install Packer?
  An older version of packer was found installed (0.7.2). Otto requires
  version 0.8.6 or higher. Otto can install the latest version of packer
  for you (0.8.6). Would you like Otto to update packer for you?

==> Detecting infrastructure credentials for: otto-getting-started (aws)
    Cached and encrypted infrastructure credentials found.
    Otto will now ask you for the password to decrypt these

  saved credentials that are password protected. Please enter the password

Apply complete! Resources: 2 added, 0 changed, 0 destroyed.

The state of your infrastructure has been saved to the path
below. This state is required to modify and destroy your
infrastructure, so keep it safe. To inspect the complete state
use the `terraform show` command.

State path: /var/folders/b5/446vyv6x0sb6w0p23w1yjy_9cmhhvg/T/otto-tf876303855/state

Outputs:

  url = http://[自動で割り当てられたホスト名].compute-1.amazonaws.com/

ここで最後にurlが表示されたので、アクセスしてみましょう。正常に表示されればデプロイ完了です!

最後に

ここまでとりあえずチュートリアルに書いてある通りにやってみましたが、非常に簡単に開発環境と本番環境を扱えるのは良いですね。 内部のツールには使い慣れているツールが多数使われているので勘所もつかみやすいと思います。 今後も注目のプロダクトといって間違いないでしょう。
