我有一个Ansible playbook，它具有启动EC2实例的角色，并允许用户指定有关该实例的变量，例如名称，节点类型，实例大小等。我希望角色在该实例中多次执行相同的剧本，并且每次执行使用不同的变量，以便我可以，例如，设置具有不同名称的多个EC2实例，否则它们是相似的。当我多次包含角色并更改变量时（参见下面的示例），只执行剧本中的第一个角色实例（在本例中为＆＃34; app-prod-01＆＃34;），第二个实例一个被跳过。
如何在同一个剧本中为每个角色任务使用不同的变量多次执行角色任务？
剧本如下：
production-site-prod.yml:
- hosts: localhost
connection: local
gather_facts: false
vars_files:
- vars/prod.yml
- vars/vpc-cfn.yml
roles:
- role: app-aws-prod
name: "app-prod-01"
node_type: application
instance_type: m4.xlarge
subnet: "{{ subnetapp1 }}"
elbs:
- app-public
- app-private
- role: app-aws-prod
name: "app-prod-02"
node_type: application
instance_type: m4.xlarge
subnet: "{{ subnetapp2 }}"
elbs:
- app-public
- app-private
角色app-aws-prod看起来像这样：
main.yml
- name: validate arguments 1/2
assert:
that:
- prefix == ""
- suffixes == [""]
when: name != ""
- name: validate arguments 2/2
assert:
that:
- prefix != ""
- suffixes != [""]
when: name == ""
- include: sg.yml
- include: iam.yml
- include: ec2-instance.yml
我的ec2-instance.yml看起来像这样：
ec2-instance.yml
- name: launch instances
ec2:
key_name: "{{ key_name }}"
group_id: "{{ sgcommon }},{{ project_sg.group_id }},{{ app_sg.group_id }}"
instance_type: "{{ instance_type }}"
image: "{{ image_ami }}"
region: "{{ region }}"
vpc_subnet_id: "{{ subnet }}"
assign_public_ip: no
exact_count: 1
ebs_optimized: yes
instance_profile_name: "{{ iam.stack_outputs.iamprofile }}"
count_tag:
Name: "{{ name }}{{ prefix }}{{ item }}"
Environment: "{{ environment_name }}"
Project: "{{ project_name }}"
node_type: "{{ node_type }}"
instance_tags:
Name: "{{ name }}{{ prefix }}{{ item }}"
Environment: "{{ environment_name }}"
Project: "{{ project_name }}"
node_type: "{{ node_type }}"
wait: yes
wait_timeout: 300
with_items: "{{ suffixes }}"
register: ec2_instance
- include: volume.yml
vars:
volume_type: 'temp'
volume_size: "{{ temp_volume_size }}"
device_name: '/dev/xvdf'
volume_retention: 10
- include: route53.yml
- include: elb.yml
当我在--list-tags上使用ansible-playbook标志时，我看到了我期望的输出，每个角色都有相同的任务集并显示它们：

根据评论中的其他信息回答：
我有一个错误，我没有在这里包括因为我认为它不相关 - 最后一个任务（不在ansible-playbook输出中）是将EC2实例附加到ELB，它失败了。 ..
如果主机上的任何任务失败（除非您指定ignore_errors: yes），请将此主机标记为失败并停止执行剩余任务。
所以，你只有一个主持人localhost，当它被标记为失败时，剧本的执行就会停止。
