AnsibleでDocker containerをプロビジョニングする

テスト環境

• pythonとSSH入りの被provision Dockerコンテナ(AnsibleがSSHで接続し、python経由で命令解釈させる為必要)
  • https://hub.docker.com/r/eugenes1/python-sshd を使ってテストする
• docker containerを動かせる環境

  $ docker -v
  Docker version 20.10.23, build %{shortcommit_cli}
  

• ansibleが叩ける環境

  $ ansible --version
  ansible [core 2.14.4]
  ...
  python version = 3.11.2 (main, Feb  8 2023, 00:00:00) [GCC 12.2.1 20221121 (Red Hat 12.2.1-4)] (/usr/bin/python3)
  

動かしてみる

• 被provision docker container run && IP取得 ```console $ docker run -d -p 2222:22 eugenes1/python-sshd c75c3b9bddb9b1fdbe846fc48f528866c1c071c6a7936c72dab05a5efbb665f8

$ docker inspect c75c3b9bddb9b1fdbe846fc48f528866c1c071c6a7936c72dab05a5efbb665f8 | grep IPAddress “SecondaryIPAddresses”: null, “IPAddress”: “172.17.0.2”, “IPAddress”: “172.17.0.2”,

- ansible inventoryファイル作成
```console
$ vim hosts.yml
docker:
  hosts:
    172.17.0.2:

• コンソールからansible通ること確認 ```console $ ansible -i hosts.yml docker -m file -a “path=/var/tmp/test state=touch” -u root -k -e ansible_python_interpreter=/usr/local/bin/python -e ‘ansible_ssh_args=”-o ControlMaster=no”’ SSH password: 172.17.0.2 | CHANGED => { “changed”: true, “dest”: “/var/tmp/test”, “gid”: 0, “group”: “root”, “mode”: “0644”, “owner”: “root”, “size”: 0, “state”: “file”, “uid”: 0 }
