Ansible:将评估变量传递给包含

Question

我有一个Ansible Playbook,可以调用另一个传递参数的playbook.这很好,但是当我尝试传入变量时,Ansible会爆炸.这是我的剧本:

---
- name: This is the toplevel play for orchestration
  hosts: nogroup
  vars:
    customer: myCustomer
  sudo: yes
- include: amazon.yml application=FooServer instance_type=t2.micro instance_count=1 customer={{ customer }}
- include: amazon.yml application=BarServer instance_type=t2.micro instance_count=1 customer={{ customer }}

我试着跑:

ansible-playbook orchestration.yml -e "customer=otherCustomer"

我收到此错误:

Traceback (most recent call last):
  File "/usr/local/Cellar/ansible/1.7.2/libexec/bin/ansible-playbook", line 5, in <module>
    pkg_resources.run_script('ansible==1.7.2', 'ansible-playbook')

关于如何允许我将命令行中设置的变量传递到我的剧本中的多个级别包含的任何想法？

Answer 1

如果没有更多的上下文很难重现您的问题,但我的猜测是您的问题来自于您尝试将变量分配customer给自身的事实.

在游戏中定义的变量由后续include语句继承.因此,由于您已经在游戏级别通过以下方式对其进行了定义,因此无需customer={{customer}}在include语句末尾添加:

  vars:
    customer: myCustomer

注意:此变量将被任何通过命令行-e选项设置的新值覆盖.

试试这样的剧本:

---
- name:  This is the toplevel play for orchestration
  hosts: nogroup
  vars:
    customer: myCustomer
  sudo: yes
- include: amazon.yml application=FooServer instance_type=t2.micro instance_count=1
- include: amazon.yml application=BarServer instance_type=t2.micro instance_count=1

并使用对{{customer}}文件内任务的评估amazon.yml.

Answer 2

到那里有同样的问题。解决如下：

---
- include: common.yml
- include: redis.yml
    redis_port="{{ airflow_redis_port }}"
    redis_bind="{{ airflow_redis_host }}"
