我怎樣才能用一個劇本中的不同變量多次執行一個Ansible角色？

我有一個Ansible手冊，它具有啓動EC2實例的角色，並允許用戶指定有關該實例的變量，例如名稱，節點類型，實例大小等。我希望角色在同一時間執行多次劇本，並且每次執行都使用不同的變量，以便我可以例如使用不同的名稱來設置多個類似的EC2實例。當我多次包含角色並更改變量（請參閱下面的示例）時，只會執行劇本中角色的第一個實例（本例中爲「app-prod-01」），並跳過第二個角色。我怎樣才能用一個劇本中的不同變量多次執行一個Ansible角色？

如何從同一個劇本中多次使用不同的變量來執行角色任務？

的劇本是這樣的：

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

中的作用及應用-AWS-PROD看起來是這樣的：

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看起來是這樣的：

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

當我在ansible-playbook上使用--list-tags標誌時，我看到了我期望的輸出，每個角色有一組相同的任務，他們都顯示：

當第二個角色被跳過時，請添加'ansible-playbook'的輸出。一般來說，這個語法應該可以正常工作。 –

@KonstantinSuvorov「ansible-playbook」的輸出並不表示任何問題;它會在完成第一個角色的最後一項任務後停止。無論如何，我會將它添加到問題中。 – LegendaryDude

有問題，你有'production-site.yml'和輸出'production-site-prod.yml'。這個可以嗎？檢查'ansible-playbook --list-tasks。/ projects/app/production/production-site-prod.yml' –

回答的基礎上，額外的信息來自評論：

有我沒有在這裏所包含的誤差是因爲我沒有認爲它是相關的 - 最後一項任務（不在劇本中的劇本輸出中）是將EC2實例附加到ELB上，因此失敗...

如果任何任務主機失敗（除非您指定ignore_errors: yes），否則可以將此主機標記爲失敗並停止執行其餘任務。

所以，你只有一個主機localhost，當它被標記爲失敗時，停止執行劇本。

我怎樣才能用一個劇本中的不同變量多次執行一個Ansible角色？
