Test Kitichen を試す

2017.07.12

cookbook をつくる

chef コマンドで cookbook をつくります。

$ chef generate cookbook cheftest
Generating cookbook cheftest
- Ensuring correct cookbook file content
- Ensuring delivery configuration
- Ensuring correct delivery build cookbook content

Your cookbook is ready. Type `cd cheftest` to enter it.

There are several commands you can run to get started locally developing and testing your cookbook.
Type `delivery local --help` to see a full list.

Why not start by writing a test? Tests for the default recipe are stored at:

test/smoke/default/default_test.rb

If you'd prefer to dive right in, the default recipe can be found at:

recipes/default.rb

$ tree cheftest/
cheftest/
├── Berksfile
├── README.md
├── chefignore
├── metadata.rb
├── recipes
│   └── default.rb
├── spec
│   ├── spec_helper.rb

└── test
    └── smoke
        └── default
            └── default_test.rb

7 directories, 8 files

こんな感じになります。以下、この cheftest の中で作業。

Test Kitchen の設定

Test Kitchen の設定は .kitchen.yml に書かれているらしい。内容は、

---
driver:
  name: vagrant

provisioner:
  name: chef_zero
  # You may wish to disable always updating cookbooks in CI or other testing environments.
  # For example:
  #   always_update_cookbooks: <%= !ENV['CI'] %>
  always_update_cookbooks: true

verifier:
  name: inspec

platforms:
  - name: ubuntu-16.04
  - name: centos-7.3

suites:
  - name: default
    run_list:
      - recipe[cheftest::default]
    verifier:
      inspec_tests:
        - test/smoke/default
    attributes:

という感じ。

driver
テスト環境のドライバ。vagrant の他に、EC2 とか docker とかあるよう。
provisioner
プロビジョナーとしては、chef-solo や ansible も使えるみたい。
verifier
Test Kitchen のベリファイステップに使うツールを指定する。Serverspec とかも使えるみたい。
platforms
テストをおこなうプラットホーム。複数定義できるけど今回は ubuntu-16.04 だけにする。
suites
テストスイート。とりあえずこのまま。

最終的に .kitchen.yml はこんな感じに。

とりあえず、ここまでの動作

動かしてみる。

長いけどこんな感じ。Chef 側から Vagrant をコントロールするという感じなんだろうか（まだ理解していない）。vagrant ssh のように ssh で入ることもできる。

$ kitchen login default-ubuntu-1604

Chef: 13.2.20

/opt/chef に Chef 関連のものが入っているようです。起動しているインスタンスのリストは以下のように確認できた（ホスト側からです）。

$ kitchen list

次は実際にレシピをつくってみる。
