ansible - 如何根据远程主机在本地主机上执行命令

Question

在我的剧本中我有这个:

- name: compile 
  hosts: localhost
  gather_facts: false
  tasks:
  - name: compile binary
    local_action: command make build FOO=foo1

如果主机是 bar-1 或 bar-2，我想在本地主机上执行 make build FOO=bar1 一次 (它们都在 bars 组中，因此按组区分也可以)。我尝试使用 when:

  - name: compile binary
    local_action: command make build FOO=foo1
    when: (inventory_hostname != "bar-1") and (inventory_hostname != "bar-2")
  - name: compile binary
    local_action: command make build FOO=bar1
    when: (inventory_hostname == "bar-1") or (inventory_hostname == "bar-2")

但是inventory_hostname始终是localhost。

在我的主机中我有

[foos]
foo-1 ...
foo-2 ...

[bars]
bar-1 ...
bar-2 ...

我将其运行为

ansible-playbook -i provision/hosts -l localhost,bars provision/deploy.yml

这对我来说效果很好:

---
- hosts: localhost,test-server
  gather_facts: no
  tasks:
    - shell: echo {{ inventory_hostname }}
      delegate_to: localhost

命令在本地主机上执行，但打印localhost和test-server。
