使用python3 virtualenv的Ansible无法与python3站点软件包一起使用

时间：2020-04-24 07:31:37

标签： python python-3.x ansible

如何复制问题：

  1. 安装Ansible“外部”虚拟环境/usr/bin/python3 -m pip install ansible
  2. 安装python3虚拟环境python3 -m venv /usr/local/kaas_virtualenv
  3. 在虚拟环境/usr/local/kaas_virtualenv/bin/python3 -m pip install jmespath中安装python模块

可用的剧本和广告资源：

playbook.yaml 

---
- hosts: control_host
  gather_facts: yes
  become: no
  environment:
    PYTHONPATH: "/usr/local/kaas_virtualenv/lib/python3.7/site-packages"

  vars:
    my_users:
      - password: 123
        username: broker
      - password: 321
        username: broker2
      - password: 213
        username: broker3

  tasks:
    - name: print users
      debug:
        msg: "users = {{ my_users|json_query('[*].username') }}"

server_inventory 

[control_host]
localhost

[control_host:vars]
ansible_connection=local
ansible_python_interpreter=/usr/local/kaas_virtualenv/bin/python3

运行剧本：ansible-playbook -i server_inventory playbook.yaml

预期输出：

可安装： 

bash-4.2# ansible --version
ansible 2.9.6
  config file = /ansible-dev/swap/ansible.cfg
  configured module search path = ['/ansible-dev/swap/library']
  ansible python module location = /usr/local/lib/python3.7/site-packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.7.6 (default, Feb 26 2020, 20:54:15) [GCC 7.3.1 20180712 (Red Hat 7.3.1-6)]

即使我激活virtualenv . /usr/local/kaas_virtualenv/bin/activate并运行ansible-playbook ansible-playbook -i server_inventory playbook.yaml -vvvv

，也会出现问题

在激活 virtualenv的情况下运行剧本： 

(kaas_virtualenv) bash-4.2# ansible-playbook -i server_inventory playbook.yaml -vvvv

  config file = /ansible-dev/swap/ansible.cfg

使用virtualenv 已激活来检查pythom模块：

(kaas_virtualenv) bash-4.2# python -c "import jmespath"
(kaas_virtualenv) bash-4.2#

使用virtualenv 停用检查pythom模块：

bash-4.2# python -c "import jmespath"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named jmespath
bash-4.2#

存在python模块的唯一地方：

bash-4.2# find / -name jmespath
/usr/local/kaas_virtualenv/lib/python3.7/site-packages/jmespath
bash-4.2#

可用的过滤器插件 未使用ansible_python_interpreter。过滤器插件必须遵循Ansible安装，并具有安装Ansible的依赖关系。

过滤器始终在控制器上运行，因为模板仅在控制器上发生，否则将需要jinja2 +将所有清单+所有变量传递到远程，出于许多原因我们不这样做。
