Ansible该任务包括带有未定义变量的选项

问题描述

我正在使用ansible部署网站。但是我得到这个错误：

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'name': u'{{ magento_project_user }}'}]: {{ http_group_name }}: 'http_group_name' is undefined"}

我知道有一些未定义的东西，但是事实是，它是由其他人开发的，应该可以正常工作，而这个其他人已经不在了。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，就像我说的那样，我知道http_group_name是未定义的，但是我该如何定义呢？我该如何调试？

我注意到在distro-vars中定义了http_group_name，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。但是我的发行版是Ubuntu 20.04。可能是问题吗？我应该创建一个Ubuntu-20.04.yml吗？ 谢谢

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

解决方法

问题是发行版。自从我在容器上使用debian 10以来，我在debian 9上做了一个新的容器，它起作用了。
