概要

こちらの内容も以前noteで書いた記事を見直ししてリメイクしたものになっています。あの時は、ansible-benderの学習を目的にしており、内部で動いているPodmanとBuildahについて何も知らない状態で書いていたので、見直すと少し変な表現もありましたので、リメイクというよりもう一度書き直して、ansible-benderでコンテナイメージを作成してみたというタイトルに直して書き記していこうと思います。

ansible-benderについて

ansible-benderはAnsible Playbookを使ってコンテナイメージを作成できるツールです。
https://github.com/ansible-community/ansible-bender
かつて、ansible-containerというツールでPlaybookによるコンテナ管理を実現できましたが、現在ansible-containerは開発が終了しております。
https://github.com/ansible/ansible-container
ansible-benderは、ansible-containerの後継機として機能を引き継いだツールとなっております。
pipパッケージからインストールできます。
pip install ansible-bender

機能

公式のGitHubの説明に書いてあるとおりですが、自身の理解のためにいくつかを日本語訳として記載します。

  • buildahを使うことでコンテナイメージをビルドできる
  • ビルド中にボリュームのマウントが可能
  • タスク実行でキャッシュを活用することで高速化
  • タグstop-layeringを付けることで、イメージレイヤーの作成を止めることができる
  • イメージのpushをして他のレジストリやdocker daemonなどにイメージを送ることができる

オプションコマンド

ansible-benderには以下のコマンドが用意されています。

  • build Playbookを指定して新しいコンテナイメージのビルド
  • list-builds ansible-benderでビルドしたイメージのリスト表示
  • get-logs Playbookを実行したときのログを表示
  • inspect <ビルドID> ビルド内の詳細なメタデータの表示。ビルドIDはlist-buildsで取得可
  • push イメージを他の場所へ送る
  • clean ディスク上に存在しないイメージの削除
  • init 変数の用意されたテンプレートPlaybookを作成
テンプレート

      target_image:

        cmd: /command.sh
        name: $project

  - name: install dependencies needed to run project $project

      name:
      - a_package
      - another_package
      state: present

必須要件

冒頭でも述べたように、ansible-benderはpodmanとbuildahが内蔵している必要があります。(当たり前ですが、ansibleも必要です。)
そしてコンテナイメージを作成する際、Pythonのインストールされたベースイメージが必要です。この時、Pythonのバージョンは2系でも3系でも大丈夫です。
こちらの方が紹介しているPythonを含む最小コンテナイメージをあらかじめ作成しておくことをお勧めします。ansible-bender でコンテナイメージを作成する

Dockerfile
FROM debian:buster

RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y python3 && apt-get clean

コンテナイメージの作成

それではansible-benderを使ってコンテナイメージを作成していきます。
作成するコンテナイメージですが、以前紹介したNuxt.jsコンテナイメージをansible-benderで作成できるか検証していきます。
https://zenn.dev/yuta28/articles/37b2990f07d5643cfa56
またベースとなるコンテナイメージは、通常でしたら上に書かれている最小Pythonのイメージでよいのですが、今回はNodeを事前に入れておきたいので、以下のDockerfileを基にしたコンテナイメージを用意しました。

Dockerfile
FROM node:latest
WORKDIR /app
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y python3 rsync && apt-get clean

ちなみに、rsyncを入れているのはansibleでディレクトリコピーするのに便利なsynchronizeモジュールを利用できるようにするためです。
ベースとなるコンテナイメージが用意できましたら、続いては構成ディレクトリです。

├── Prototype
│   └── app/(Nuxt.jsのひな型)  
└── build_nuxtimage.yml

前回と同じように事前にNuxt.jsのひな形となる各種一式をローカルに用意します。
dockerモジュールから作成したときはDockerfileでコンテナイメージを作成しましたが、ansible-benderでは、Playbookからコンテナイメージを作成できますので、Dockerfileは今回作っておりません。
Playbookの中身は以下の通りです。

build_nuxtimage.yml
---
- name: Build Nuxt.js image
  hosts: all
  vars:
    ansible_bender:
      base_image: "localhost/node-python3"
      ansible_extra_args: "-vvv"
 
      target_image:
        name: yuta28/bender-test
        working_dir: /app
        environment: 
          NUXT_HOST: 0.0.0.0
        labels:
          built-by: '{{ ansible_user }}'
        cmd: "yarn run dev"        

  tasks:
  - name: Copy Prototype parts
    copy:
      src: "{{ item }}"
      dest: /app/
    with_items:
      - "{{ playbook_dir }}/Prototype/app/package.json"
      - "{{ playbook_dir }}/Prototype/app/yarn.lock"
  
  - name: Yarn install
    command: "yarn install"

  - name: Copy Prototype
    synchronize:
      src: "{{ playbook_dir }}/Prototype/app" 
      dest: /app

Dockerfile内のRUN命令箇所はcommandモジュール、COPY命令箇所はsynchronizeモジュール、CMD命令はtarget_image内のcmd変数に変換してPlaybookでコンテナのイメージ作成文を作ってみました。
作成後、ansible-benderコマンドで実行します。ansible-bender build build_nuxtimage.yml

失敗

結論から話しますと失敗しました。
タスクCopy Prototypeの箇所でsynchronizeモジュールの処理が終わらず、先に進まない状態になりました。

はっきりとした原因は掴めませんが、コピーするファイルの量が多いことが原因ではないかと推測しました。

$ ls -R app | wc -l
36358 ←3万以上のファイル群

どうしたものかと途方にくれていたところ、ansibleに詳しいフォロワーの方から大きなファイルをansibleで直接送るのではなく、AWS S3を経由して送ったほうがよいというアドバイスをいただきましたので、aws_s3というモジュールがansible-benderで使えるか検証するためのテスト用Playbookを作成しました。

build_nuxtimage.yml
---
- name: Build Nuxt.js image
  hosts: all
  gather_facts: false
  vars:
    ansible_python_interpreter: /usr/bin/python3
    ansible_bender:
      base_image: "localhost/node-python3"
      ansible_extra_args: "-vvv"

      target_image:
        name: yuta28/bender-test
        working_dir: /app
        environment: 
          NUXT_HOST: 0.0.0.0
        labels:

  tasks:

      object: app/nuxt.config.js
      src: "{{ playbook_dir }}/Prototype/app/nuxt.config.js"
      mode: put

こちらのPlaybookを実行すると以下のエラーが出ました。

If the required library is installed, but Ansible is using the wrong Python interpreter, please consult the documentation on ansible_python_interpreter"
}

必要なPythonライブラリが不足していると出ていますが、boto3もbotocoreもインストールはされています。
Python interpreterの指定が間違っているのというのがよく分からず、一応冒頭で明示的にansible_python_interpreter: /usr/bin/python3を指定しましたが、結果は変わりませんでした。
こちらの内容はteratailにも質問を投稿していますので、わかるかたがいましたらご教授お願いいたします。

プランB

次に挑戦してみたのが、appディレクトリをアーカイブして、コンテナ内で展開する方法です。
Ansibleにはファイルの圧縮や展開を実施してくれうモジュールがありますので、それを使います。
archive
unarchive
そして出来上がったPlaybookがこちらです。

build_nuxtimage.yml
---
- name: Build Nuxt.js image
  hosts: all
  gather_facts: false
  vars:
    ansible_python_interpreter: /usr/bin/python3
    ansible_bender:
      base_image: "localhost/node-python3"
      ansible_extra_args: "-vvv"

      target_image:
        name: yuta28/bender-test
        working_dir: /app
        environment:
          NUXT_HOST: 0.0.0.0
        labels:
          built-by: '{{ ansible_user }}'
        cmd: "yarn run dev"

  tasks:
  - name: Copy Prototype parts
    copy:
      src: "{{ item }}"
      dest: /app/
    with_items:
      - "{{ playbook_dir }}/Prototype/app/package.json"
      - "{{ playbook_dir }}/Prototype/app/yarn.lock"

  - name: Yarn install
    command: "yarn install"

  - name: Archive app directory
    delegate_to: localhost
    archive:
      path: "{{ playbook_dir }}/Prototype/app"
      dest: "{{ playbook_dir }}/Prototype/app.tar.gz"
      format: gz

  - name: Unpacks app.tar.gz
    unarchive:
      src: "{{ playbook_dir }}/Prototype/app.tar.gz"
      dest: /

archiveモジュールですが、リモート先のソースファイルをアーカイブするモジュールのため、ローカルマシン上にあるソースファイルをアーカイブするには、delegate_toでlocalhostを指定することでローカルマシンにあるappディレクトリをアーカイブできます。
アーカイブできましたら、unarchiveモジュールでコンテナ先にコピーして展開します。（copyもやってくれるので便利なモジュールですね）
このPlaybookを実行した結果がこちらです。

反省点

DockerfileからPlaybookへ変更してコンテナイメージ作成を行ないましたが、いくつかやり方が分からず、残タスクとして残っているものがあります。

telemetryによるデータ収集問い合わせの無効化設定について

Dockerfileでは以下の環境変数を設定しました。
NUXT_TELEMETRY_DISABLED=1
こちらですが、Nuxt機能の統計情報の収集問い合わせを無視する設定です。デフォルトでは有効化されており、最初にコンテナを起動すると以下のメッセージが出てきます。

yarn run v1.22.5
$ nuxt

ℹ NuxtJS collects completely anonymous data about usage.                                                                                                      11:21:11
  This will help us improving Nuxt developer experience over the time.

起動のたびに聞かれるのが煩わしいので設定で無効化しようと、変数をPlaybookに組み込みましたが、以下のエラーが出て失敗しました。

$ ansible-bender build simple-test/build_nuxtimage.yml 
There was an error during execution: variable /target_image/environment/NUXT_TELEMETRY_DISABLED is set to 1, which is not of type string

環境変数がstring型でないと怒られました。NUXT_TELEMETRY_DISABLEDはboolean型ですが、ansible-benderの環境変数はstring型のものしかセットできないのでしょうか？
対処方法としましては、app/nuxt.config.js内に以下の設定を追加しました。

nuxt.config.js
export default {
~~~~~末尾追加~~~~~
  telemetry: false
}

noneイメージが溜まり続ける

Playbook実行直後にイメージリストを調べると以下のように途中過程で作られたnoneイメージがたくさん溜まってきます。

作成後にpodman image pruneで消していますが、この辺なんとかならないのでしょうか？

所感

ansible-benderを使った感想としては思ったよりも使いにくいと感じました。
ansible-containerはコンテナイメージの作成からコンテナ起動、イメージのプッシュができたのですが、ansible-benderはコンテナイメージの作成だけに留まっており、機能としては減ったように感じます。
また、ansible-benderの開発はあまり活発ではなく、最新リリースが昨年の12月、プルリクも今年の5/18が最後になっております。(2020/9現在)
正直なところAnsibleでコンテナ管理するメリットがあまり感じられず、docker-composeやKubernetesでコンテナ管理をしたほうがいいじゃんと言われたら何も言えません。
Ansibleでコンテナ管理するメリットやansible-benderが上記2つよりも優れている点がありましたらぜひともコメントにてアドバイスお願いいたします。
