    • brew cask : 0.56.0
    • VirtualBox : 4.3.10 r93012

インストール

brew caskでインストール。

$ brew install Caskroom/cask/otto

または、下記のサイトからダウンロード。

インストールされたか確認。

$ otto
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

$ otto --version

$ otto compile
==> 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 infrastructure, 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.

DO NOT MODIFY OR DELETE THIS FILE!

This file should be checked in to version control. Do not ignore this file.

The first line is a unique UUID that represents the Appfile in this directory.
This UUID is used globally across your projects to identify this specific
Appfile. This UUID allows you to modify the name of an application, or have
duplicate application names without conflicting.

If you delete this file, then deploys may duplicate this application since
Otto will be unable to tell that the application is deployed.

    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.

内部的には、Vagrantを使って開発環境を構築しているようです。

初回コンパイル時は、仮想マシンのIPアドレスがブロードキャストアドレス(100.114.244.255)になっていました。.ottoidと.otto/を削除してコンパイルし直したところ新しいIPアドレスが割り振られました。(原因不明)
