Question

我正在尝试使用Ansible的ec2_ami模块从EC2实例创建AMI。为此，我正在运行这个角色：

---
- name: Stop instance
  ec2:
    instance_id: "{{ instanceId }}"
    region: "{{ region }}"
    state: stopped
    wait: yes

- name: Create AMI
  ec2_ami:
    region: "{{ region }}"
    instance_id: "{{ instanceId }}"
    name: "{{ asg_name }}-{{ ansible_date_time.iso8601 | regex_replace('[^a-zA-Z0-9]', '-') }}"
    wait: yes
    state: present
  register: ami

我收到此错误：

Traceback (most recent call last):
  File "/tmp/ansible_zO2i0P/ansible_module_ec2_ami.py", line 701, in <module>
    main()

Unknown parameter in input: "WaiterConfig", must be one of: DryRun, ImageIds, Owners, ExecutableUsers, Filters

我在Linux Ubuntu 14.04上运行Ansible 2.5.0版。这些是我安装的boto模块：

boto==2.45.0
boto3==1.7.0
botocore==1.4.50

我猜我有版本问题，但我不确定它是什么。此角色之前已运行，但我从版本2.0升级了Ansible。

Answer 1

问题是botocore需要升级。

sudo pip install awscli botocore boto3 -U

现在我的boto版本是

boto==2.45.0
boto3==1.7.0
botocore==1.10.0

角色运转良好。

Answer 2

我告诉任务不要等待

# CREATE THE AMI IMAGE
- name: Create AMI Image from the instance just created
  local_action:
    module: ec2_ami
    instance_id: "{{ ec2_id }}"
    wait: no

并且“waiterconfig”错误消息消失了。

如果您想检查AMI图像创建的进度，因为您不再等待任务：

- name: Check the created AMI Image exists
  local_action:    
    module: ec2_ami_facts
    owners: self
    region: "{{ region }}"
    aws_access_key: "{{ aws_akey }}"
    aws_secret_key: "{{ aws_skey }}"        
    filters:
        "tag:Name": "NameOfAMI"
        "tag:ami_completeness": "someOtherTag"
  register: ami_find
  until: ami_find.images|length > 0
  retries: 5
  delay: 10

这将检查每10秒，对于5次检查，以查看AMI是否在结果中出现。如果有1，则长度大于0.您需要在过滤器中非常具体，以便在创建ami后只有一个结果。

Answer 3

在Ansible 2.5上，按照有关更新awscli，boto3和botocore的说明进行操作，问题仍然存在。

TASK [Create AMI Image from the instance just created] ***********************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: Unknown parameter in input: "WaiterConfig", must be one of: DryRun, ImageIds, Owners, ExecutableUsers, Filters
fatal: [a_flap_prod_door_21841_a -> localhost]: FAILED!

pip模块

 - awscli==1.15.2
 - boto==2.48.0 
 - boto3==1.7.2 
 - botocore==1.10.2

创建了AMI，但没有创建任何标记。这在Ansible 2.4上不是问题。

这可以通过告诉任务不要等待来解决：

# CREATE THE AMI IMAGE
- name: Create AMI Image from the instance just created
  local_action:
    module: ec2_ami
    instance_id: "{{ ec2_id }}"
    wait: no

并且它已经完成 - 没有错误并且标签已经创建

Answer 4

这确实是Ansible 2.5的问题。这是GitHub上的错误报告：https://github.com/ansible/ansible/issues/40303

您可以应用其他答案中发布的解决方法，也可以仅返回2.4分支，直到问题解决：

pip install ansible==2.4.5

这将删除您当前的Ansible版本并安装版本2.4.5。

请注意，在撰写本文时，2.4.5是2.4分支上的最新版本。您可能要在Ansible 2.4 Changelog中查找最新版本，然后安装该版本。

为什么ec2_ami抱怨未知参数WaiterConfig？
