Ansible - 在远程主机模板中使用来自本地主机的事实 [英] Ansible - use fact from local host in remote host template

问题描述

我有一个包含本地主机角色和远程主机角色的剧本.

I have a playbook that contains roles for localhost and roles for remote hosts.

在其中一个 localhost 角色中，我设置了一个名为 git_tag 的事实.

In one of the localhost roles I set a fact called git_tag.

我想在远程主机的模板中使用这个事实.

I want to use this fact in a template for the remote hosts.

我试过了:

- name: Read Version
  set_fact:
    git_tag: "{{ package_json.stdout | from_json | json_query('version')}}"
  delegate_to: "test-server"

但是当 Ansible 到达读取具有 {{ git_tag }} 的模板的角色时，它说 git_tag 未定义.

But when Ansible reaches the role that reads the template that has {{ git_tag }} it says that git_tag is undefined.

我确定我做错了什么.我该怎么做?

I'm sure I'm doing something wrong. How can I do it?

推荐答案

您应该使用 hostvars 魔法变量:

You should use a hostvars magic variable:

{{ hostvars['localhost']['git_tag'] }}
