WindowsのWSL LinuxにてPodmanを使用するAnsible Molecule環境を構築する

Last updated at Posted at 2024-04-21

備忘

Podmanコンテナ環境をターゲットとするAnsible MoleculeによるAnsible検証環境を構成する

環境

  • Windows WSL2上Linux環境
    • Fedora Linux 39 (Container Image)
  • Podman v5.0.2

Ansible, Moleculeなどの導入

Fedora Linux 39 [hiro@DESKTOP-72JFO1B ~]$ sudo dnf install python3-pip
...

Fedora Linux 39 [hiro@DESKTOP-72JFO1B ~]$ python3 -m pip install molecule ansible-core
...

Fedora Linux 39 [hiro@DESKTOP-72JFO1B ~]$ pip3 install ansible-dev-tools
...

molecule処理におけるRole name check失敗を回避する設定

生成されたファイルのままでは、以降のmolecule処理においてRole name checkで失敗するため、以下のいずれかの対応が必要。

  • a) meta/main.ymlにおけるgalaxy_info:にnamespace: xxxxを追記
  • b) meta/main.ymlファイルを削除
  • c) molecule.ymlにてrole_name_check: 1という設定を追加 (後述)

a) meta/main.ymlにおけるgalaxy_info:にnamespace: xxxxを追記 することによるRole name check失敗回避

xxxxは任意の文字列。Ansible Galaxyでのネームスペースであり、通常はユーザー名や組織名。

meta/main.yml
galaxy_info:
  author: your name
  description: your role description
  company: your company (optional)
...

↓

Fedora Linux 39 [hiro@DESKTOP-72JFO1B myrole]$ grep -q "^  namespace:" meta/main.yml || sed -i '/^galaxy_info:/a \ \ namespace: my_galaxy_namespace' meta/main.yml

↓

meta/main.yml
galaxy_info:
  namespace: my_galaxy_namespace  # 追加。Ansible Galaxyでのネームスペース、通常はユーザー名や組織名
  author: your name
  description: your role description
  company: your company (optional)
...

b) meta/main.ymlファイルを削除 することによるRole name check失敗回避

Fedora Linux 39 [hiro@DESKTOP-72JFO1B myrole]$ rm -fr meta

molecule init scenario -d podman

moleculeの設定ファイルをpodmanドライバーを指定して生成する。
scenario名を指定していないのでdefaultというscenario名が使用される。

moleculeの設定ファイル
ここでは、1つのcentos stream8コンテナをinstanceという名前で利用することを意味している
テンプレートであり、必要に応じて書き換えを行う

c) molecule.ymlに、role_name_check: 1という設定を追加することによるRole name check失敗回避

前述のmeta/main.ymlによる対応を行っていない場合、以下の様にrole_name_check: 1という設定を追加してチェックを回避する対応が可能
