Habitat チュートリアルを実施してみる #getchef #habitat

この記事は1年以上前に投稿されました。情報が古い可能性がありますので、ご注意ください。

本稿は Chef社によるアプリ自動化プロジェクト Habitat のチュートリアルを実施してみた結果です。

Vagrant + VirtualBox で ubuntu/xenial64 を起動し、そちらでチュートリアルを行ってみます。

Habitat を始めよう

Getting started with Habitat にある通り、事前準備を行います。

Get Habitat の通りに行います。ここでは For Linux をダウンロードしておきます。ubuntu/xenial64 (Ubuntu 16.04 LTS) は 64ビット版で Linux Kernel のバージョンが 4.4 なので、64ビット版の Linux Kernel 2.6.32 以上という条件を満たしています。

GitHub のアカウントを準備します。GitHub アカウントは作成した Habitat パッケージを他者と共有する際に必要となるようです。

今回は Linux 上でチュートリアルを行うので、Docker Engine をインストールしておきます。本稿の内容を実施した際は、Docker Engine 1.11.2 以上が必要です。

ubuntu@ubuntu-xenial:~$ curl -fsSL https://get.docker.com/ | sh
:
ubuntu@ubuntu-xenial:~$

ubuntu@ubuntu-xenial:~$ sudo usermod -aG docker ubuntu
ubuntu@ubuntu-xenial:~$

Habitat 環境の作成

Set up your environment に従い、Habitat を実行する環境を作っていきます。

先にダウンロードしておいた Habitat for Linux のアーカイブを展開します。

ubuntu@ubuntu-xenial:~$ tar xvfz hab-0.7.0-20160614230104-x86_64-linux.tar.gz
hab-0.7.0-20160614230104-x86_64-linux/
hab-0.7.0-20160614230104-x86_64-linux/hab
ubuntu@ubuntu-xenial:~$

1つだけ実行バイナリが入っています。これが Habitat の CLI である hab コマンドです。

ubuntu@ubuntu-xenial:~/hab-0.7.0-20160614230104-x86_64-linux$ ./hab
hab 0.7.0/20160614230104

setup Alias for: 'cli setup'
start Alias for: 'sup start'

ubuntu@ubuntu-xenial:~/hab-0.7.0-20160614230104-x86_64-linux$

ホームディレクトリに bin ディレクトリを作成してそちらに hab コマンドを移し、パスを通しておきます。

ubuntu@ubuntu-xenial:~$ mkdir bin
ubuntu@ubuntu-xenial:~$ mv hab-0.7.0-20160614230104-x86_64-linux/hab bin/
ubuntu@ubuntu-xenial:~$
ubuntu@ubuntu-xenial:~$ export PATH=$PATH:~/bin
ubuntu@ubuntu-xenial:~$

以降、sudo コマンドを使って hab コマンドを実行していくのですが、sudo コマンドの設定によっては PATH 環境変数が引き継がれないのでパスを通した意味がなくなります。本稿で用いた ubuntu/xenial64 のデフォルト設定では PATH 環境変数が引き継がれないので、毎回パスを指定しています。

では、hab setup を root 権限で実行し、Habitat の環境を作成していきましょう。

ubuntu@ubuntu-xenial:~$ sudo ~/bin/hab setup

Habitat CLI Setup
=================

Welcome to hab setup. Let's get started.

Set up a default origin

Every package in Habitat belongs to an origin, which indicates the
person or organization responsible for maintaining that package. Each
origin also has a key used to cryptographically sign packages in that
origin.

Selecting a default origin tells package building operations such as
'hab pkg build' what key should be used to sign the packages produced.
If you do not set a default origin now, you will have to tell package
building commands each time what origin to use.

For more information on origins and how they are used in building
packages, please consult the docs at
https://www.habitat.sh/docs/build-packages-overview/

Set up a default origin? [Yes/no/quit]

まず origin と呼ばれるものを設定します。これは Habitat で作成するパッケージの所属先(個人または組織)であり、暗号署名を施す鍵を所持します。ここでは hab コマンドを実行する際にデフォルトで利用する origin を新規作成していきます。

Enter the name of your origin. If you plan to publish your packages
publicly, we recommend that you select one that is not already in use on
the Habitat build service found at https://app.habitat.sh/.

Default origin name: [default: ubuntu] cl-lab-k

origin の名前をここでは cl-lab-k としています。

Create origin key pair

It doesn't look like you have a signing key for the origin `cl-lab-k'.
Without it, you won't be able to build new packages successfully.

You can either create a new signing key now, or, if you are building
packages for an origin that already exists, ask the owner to give you
the signing key.

For more information on the use of origin keys, please consult the
documentation at https://www.habitat.sh/docs/concepts-keys/#origin-keys

Create an origin key for `cl-lab-k'? [Yes/no/quit]
» Generating origin key for cl-lab-k
★ Generated origin key pair cl-lab-k-20160617063426.

パッケージに暗号署名するための鍵を新規作成します。

GitHub Access Token

While you can build and run Habitat packages without sharing them on the
public depot, doing so allows you to collaborate with the Habitat
community. In addition, it is how you can perform continuous deployment
with Habitat.

The depot uses GitHub authentication with an access token
(https://help.github.com/articles/creating-an-access-token-for-command-line-use/).

If you would like to share your packages on the depot, please enter your
GitHub access token. Otherwise, just enter No.

For more information on sharing packages on the depot, please read the
documentation at https://www.habitat.sh/docs/share-packages-overview/

Set up a default GitHub access token? [Yes/no/quit]

GitHub との連携を行います。このチュートリアルでは実施しませんが、Habitat で作成したパッケージを他者と共有する際に利用します。以後のことを考えて、ここでは連携することとします。

Enter your GitHub access token.

GitHub access token:  ****************************************

Creating an access token for command-line use を参考に、GitHub アクセストークンを取得し、hab コマンドに入力します。

Analytics

The `hab` command-line tool will optionally send anonymous usage data to
Habitat's Google Analytics account. This is a strictly opt-in activity
and no tracking will occur unless you respond affirmatively to the
question below.

We collect this data to help improve Habitat's user experience. For
example, we would like to know the category of tasks users are
performing, and which ones they are having trouble with (e.g. mistyping
command line arguments).

To see what kinds of data are sent and how they are anonymized, please
read more about our analytics here:
https://www.habitat.sh/docs/about-analytics/

Enable analytics? [Yes/no/quit]
» Opting in to analytics
☑ Creating /home/ubuntu/.hab/cache/analytics/OPTED_IN
★ Analytics opted in, thank you!

hab コマンドには Google Analytics が内蔵されていて、匿名の利用統計を収集するようになっています。ここでは、今後の Habitat の開発に寄与することを期待して有効にしています。

CLI Setup Complete

That's all for now. Thanks for using Habitat!

ubuntu@ubuntu-xenial:~$

以上で設定は完了です。

ソースの確認

Review the source files は今回のチュートリアルで利用する Node.js アプリのソースです。後々ダウンロードと設定を行うのでこれらをファイルに書く必要はありません。

プランの作成

Create your first plan に従い、前述の Node.js アプリの Habitat パッケージを作成します。

まず、Habitat パッケージに含まれるファイルや、パッケージの設計図とも言えるプランを配置するディレクトリを作成します。ここでは plans ディレクトリ以下に mytutorialapp ディレクトリを作成し、そちらで作業します。この mytutorialapp ディレクトリ内のファイルは Docker と同じく「コンテキスト (context)」と呼びます。

ubuntu@ubuntu-xenial:~$ mkdir -p ~/plans/mytutorialapp
ubuntu@ubuntu-xenial:~$ cd ~/plans/mytutorialapp/
ubuntu@ubuntu-xenial:~/plans/mytutorialapp$

mytutorialapp ディレクトリ内にプランである plan.sh ファイルを作成します。

ubuntu@ubuntu-xenial:~/plans/mytutorialapp$ vi plan.sh
pkg_origin=cl-lab-k
pkg_name=mytutorialapp
pkg_version=0.1.0
pkg_maintainer="HIGUCHI Daisuke <d-higuchi@creationline.com>"
pkg_license=()
pkg_source=https://s3-us-west-2.amazonaws.com/${pkg_name}/${pkg_name}-${pkg_version}.tar.gz
pkg_shasum=b54f8ada292b0249245385996221751f571e170162e0d464a26b958478cc9bfa
pkg_deps=(core/node)
pkg_expose=(8080)

do_build() {
# The mytutorialapp source code is unpacked into a directory,
# mytutorialapp-0.1.0, at the root of $HAB_CACHE_SRC_PATH. If you were downloading
# an archive that didn't match your package name and version, you would have to
# copy the files into $HAB_CACHE_SRC_PATH.

# This installs both npm as well as the nconf module we listed as a
# dependency in package.json.
npm install
}

do_install() {
# Our source files were copied over to the HAB_CACHE_SRC_PATH in do_build(),
# so now they need to be copied into the root directory of our package through
# the pkg_prefix variable. This is so that we have the source files available
# in the package.
cp package.json ${pkg_prefix}
cp server.js ${pkg_prefix}

  # Copy over the nconf module to the package that we installed in do_build().
mkdir -p ${pkg_prefix}/node_modules/
cp -vr node_modules/* ${pkg_prefix}/node_modules/
}
ubuntu@ubuntu-xenial:~/plans/mytutorialapp$

pkg_origin, pkg_name, pkg_version

パッケージの識別情報です。

pkg_maintainer, pkg_license

メンテナの連絡先とパッケージのライセンスです。

pkg_source, pkg_shasum

ソースアーカイブの取得先と、ソースアーカイブが正しいことを検証するための SHA256 チェックサムです。一致しない場合はビルドエラーになります。

pkg_deps, pkg_build_deps

パッケージのアプリの実行時と、ビルド時のそれぞれの依存関係です。

親子関係にある依存関係をすべて列挙する必要はありません。また、実行時の依存関係はビルド時にもインストールされるので、pkg_build_deps は省略可能な場合もあります。

pkg_bin_dirs, pkg_include_dirs, pkg_lib_dirs

パッケージをビルドして配置するバイナリ、インクルード、ライブラリの各ディレクトリの定義です。

pkg_expose

指定のポートを公開します。

do_build, do_install

ビルドおよびインストール時の既存のコールバック関数を上書きします。

これでプランの作成ができたので、これをもとにして Habitat パッケージの作成を行います。クリーンな環境でパッケージの作成を行うため、「スタジオ (studio)」を起動します。root 権限で hab studio enter を実行します。

フックの追加

先の Habitat パッケージはサービスを何も起動しないため、何も起こりません。そこで Add hooks to your plan に従い、フックスクリプトを追加します。

フックスクリプトを格納するディレクトリ /src/hooks を作成し、そちらに移動します。

[8][default:/src:0]# cd /src/
[9][default:/src:0]# mkdir hooks
[10][default:/src:0]# cd hooks/
[11][default:/src/hooks:0]#

init ファイルには初期化時の挙動を定義し、run ファイルにはサービスまたはアプリ起動方法を定義します。

[12][default:/src/hooks:0]# vi init
#!/bin/sh
#
ln -sf {{pkg.path}}/package.json {{pkg.svc_path}}
ln -sf {{pkg.path}}/server.js {{pkg.svc_path}}
ln -sf {{pkg.path}}/node_modules {{pkg.svc_path}}
[13][default:/src/hooks:0]#

[13][default:/src/hooks:0]# vi run
#!/bin/sh
#
cd {{pkg.svc_path}}
npm start
[14][default:/src/hooks:0]#

設定の追加

ここでは Add configuration to your plan に従って、設定を動的に変更できるように調整します。

まず、/src/config ディレクトリを作成し、もともとの静的な設定ファイルを作成します。

[14][default:/src/hooks:0]# cd /src/
[15][default:/src:0]# mkdir config
[16][default:/src:0]# touch config/config.json
[17][default:/src:0]#

[17][default:/src:0]# vi config/config.json
{
"message": "Hello, World!",
"port": "8080"
}
[18][default:/src:0]#

固定値である "Hello, World!" と "8080" をテンプレート変数に書き換えます。ユーザ定義値は cfg. から始まります。

[18][default:/src:0]# vi config/config.json
{
"message": "{{cfg.message}}",
"port": "{{cfg.port}}"
}
[19][default:/src:0]#

ユーザ定義のテンプレート変数のデフォルトは TOML (和訳) というシンプルな言語によって書かれています。

[19][default:/src:0]# touch default.toml
[20][default:/src:0]#

[20][default:/src:0]# vi default.toml
# Message of the Day
message = "Hello, World!"

# The port number that is listening for requests.
port = 8080
[21][default:/src:0]#

サービスを実行

Run your service に従い、改めて Habitat パッケージのビルドを行います。

[1][default:/src:0]# build
:
:
:
[2][default:/src:0]#

hab pkg export docker コマンドを用いると、指定の Habitat パッケージを Docker イメージとして書き出すことができます。指定方法は origin/packagename です。

[2][default:/src:0]# hab pkg export docker cl-lab-k/mytutorialapp

スタジオから exit し、docker images コマンドで Docker イメージを確認します。

ubuntu@ubuntu-xenial:~$ docker images

この Docker イメージを docker run コマンドで起動します。

ubuntu@ubuntu-xenial:~$ docker run -it -p 8080:8080 cl-lab-k/mytutorialapp

別ターミナルでアクセスしてみます。

ubuntu@ubuntu-xenial:~$ curl http://127.0.0.1:8080/
Hello, World!ubuntu@ubuntu-xenial:~$

先に設定していたデフォルトのメッセージが表示されています。

次に -e オプションで環境変数を与えて設定を上書きしてみます。

ubuntu@ubuntu-xenial:~$ docker run -e HAB_MYTUTORIALAPP='message="Habitat rocks!"' -it -p 8080:8080 cl-lab-k/mytutorialapp
hab-sup(MN): Starting cl-lab-k/mytutorialapp

別ターミナルでアクセスしてみます。

ubuntu@ubuntu-xenial:~$ curl http://127.0.0.1:8080/
Habitat rocks!ubuntu@ubuntu-xenial:~$

上書きしたメッセージが表示されています。

おわりに

これでチュートリアルは終了です。あくまで触りの部分だけなので、Habitat の特長についてなかなか伝わらないと思います。しかし、このチュートリアルを踏まえることで、Habitat の概念をより深く知るための手がかりになると思います。

引き続き、Habitat について追っていきたいと思います。
