Ansible 该任务包含一个带有未定义变量的选项

Question

我正在使用 ansible 来部署网站。但我得到这个错误：

fatal: [lxc-server]: FAILED! => {"failed": true, "msg": "The task includes an option with an undefined variable. The error was: [{u'authorized_keys': u'{{ delivery_authorized_keys }}', u'group': u'{{ magento_webserver_group }}', u'name': u'{{ magento_project_user }}'}]: {{ http_group_name }}: 'http_group_name' is undefined\n\nThe error appears to have been in '/home/jredor/projets/webstore/architecture/provisioning/provision.yml': line 32, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n    - name: \"Prepare the delivery_users object\"\n      ^ here\n\nexception type: <class 'ansible.errors.AnsibleUndefinedVariable'>\nexception: [{u'authorized_keys': u'{{ delivery_authorized_keys }}', u'group': u'{{ magento_webserver_group }}', u'name': u'{{ magento_project_user }}'}]: {{ http_group_name }}: 'http_group_name' is undefined"}

我知道有些东西未定义，但问题是，它是由其他人开发的，它应该可以完美运行，而这个其他人已经不存在了。这是provision.yml：

    when: magento_app_etc_env.stat.exists

# Update permissions
  - include: includes/permissions-tasks-full.yml

错误在那里触发：

  - name: "Prepare the delivery_users object"
  set_fact: delivery_users="{{ tmp_delivery_users }}"

所以，就像我说的，我知道 http_group_name 是未定义的，但我该如何定义呢？我该如何调试？

我注意到 http_group_name 是在 distro-vars 中定义的，其中每个 distri 都有一个 yml 文件。有 CentOS-7、Debian-8、Debian-9、RadHat-7 和 Ubuntu-16.04。但我的发行版是 Ubuntu 20.04。会不会是问题？我应该创建一个 Ubuntu-20.04.yml 吗？ 谢谢

编辑： 我的 env.php.j2

我这里没有任何“http_group_name”。这是错误吗？我应该在那里定义它吗？如果是这样，我该怎么做？

问题出在发行版上。由于我在容器上使用了 debian 10，因此我在 debian 9 上创建了一个新容器，并且它工作正常。
