Question

尝试构建可在virtualenv环境上安装apache-ariflow的剧本。无法在virtualenv文件夹内执行命令。以下是我的剧本和错误。

Playbook内容：-

    - name: Active virtual Environment
      shell: source bin/activate
      args:
        chdir: "{{ directory }}"

    - name: Upgrade pip to latest version
      shell: pip install --upgrade pip

    - name: Execute export GPL
      shell: export AIRFLOW_GPL_UNIDECODE=yes

    - name: Execute export slugify
      shell: SLUGIFY_USES_TEXT_UNIDECODE=yes

    - name: Install airflow
      pip: name=apache-airflow state=present

Answer 1

任务是独立的，因此在以下任务中将无法导出AIRFLOW_GPL_UNIDECODE=yes之类的变量，如果要传递环境变量，请在此任务中使用关键字environment:传递它

 - name: Install airflow
   pip: name=apache-airflow state=present
   environment:
     SLUGIFY_USES_TEXT_UNIDECODE: yes
     AIRFLOW_GPL_UNIDECODE: yes

（请参阅https://docs.ansible.com/ansible/latest/user_guide/playbooks_environment.html）

Answer 2

pip ansible模块也具有virtuanlenv参数。文件：https://docs.ansible.com/ansible/latest/modules/pip_module.html

- name: Install airflow
   pip: name=apache-airflow state=present
   virtualenv: '{{ airflow_virtualenv }}'
   virtualenv_python: '{{ airflow_python_version }}'
   environment:
     SLUGIFY_USES_TEXT_UNIDECODE: yes
     AIRFLOW_GPL_UNIDECODE: yes
