在--extra-vars中传递数组-Ansible [英] Pass array in --extra-vars - Ansible

问题描述

如何在Ansible剧本中将yaml数组传递给--extra-vars. Ansible文档未声明其语法，我也无法在任何互联网资源上找到它.

我的意思是如果我有一部剧本:

---
  - hosts: {{hostName}}
  - remote_user: admin
  ...

那我应该给我的剧本打电话

ansible-playbook DeployWar.yml --extra-vars="hostName=tomcat-webApp"

但是我想在两个服务器(例如tomcat-webApp和tomcat-all)上运行此剧本，我想从外部进行控制，即使用--extra-vars.我试图做的是:

ansible-playbook DeployWar.yml --extra-vars="hostName=[tomcat-webApp, tomcat-all]"

ansible-playbook DeployWar.yml --extra-vars="hostName={tomcat-webApp, tomcat-all}"

ansible-playbook DeployWar.yml --extra-vars="[{hostName: tomcat-webApp}, {hostName: tomcat-all}]"

但是在所有情况下，剧本都无法在我的通话中声明语法错误. 任何帮助表示赞赏.

解决方案

回答第一个问题如何在Yasible剧本中将yaml数组传递给--extra-vars." 您可以将> json格式的字符串传递给Extra-vars ./p>

这是一个例子剧目:

- hosts: all
  gather_facts: no
  tasks:
    - debug: var=test_list

以及如何将test_list传递给ansible-playbook:

ansible-playbook -c local -i localhost, test.yml --extra-vars='{"test_list": [1,2,3]}'

尽管您可以为主机使用变量，但我还是建议您检查Ansible的主机管理机制，该机制是库存与--limit选项.

How can I pass yaml array to --extra-vars in Ansible playbook. Ansible documentation does not declares its syntax nor I can find that on any internet resource.

I mean if I have a playbook:

---
  - hosts: {{hostName}}
  - remote_user: admin
  ...

Then I should call my playbook like

ansible-playbook DeployWar.yml --extra-vars="hostName=tomcat-webApp"

But I want to run this playbook on two servers say tomcat-webApp and tomcat-all, and I want to control it from out side i.e. using --extra-vars. What I have tried to do is:

ansible-playbook DeployWar.yml --extra-vars="hostName=[tomcat-webApp, tomcat-all]"

ansible-playbook DeployWar.yml --extra-vars="hostName={tomcat-webApp, tomcat-all}"

ansible-playbook DeployWar.yml --extra-vars="[{hostName: tomcat-webApp}, {hostName: tomcat-all}]"

But in all cases playbook fails declaring a syntax error in my call. Any help appreciated.

解决方案

To answer your first question "How can I pass yaml array to --extra-vars in Ansible playbook." you can pass in a json formatted string to extra-vars.

Here is an example play:

- hosts: all
  gather_facts: no
  tasks:
    - debug: var=test_list

And how to pass in test_list to ansible-playbook:

ansible-playbook -c local -i localhost, test.yml --extra-vars='{"test_list": [1,2,3]}'

Though you can use a variable for hosts I recommend checking out Ansible's mechanism for host management which is inventory in conjunction with the --limit option.
