Question

我想在清单查询中使用清单主机名来配置使用相同模板但变量不同的服务器

/ etc / ansible / hosts

[nodes]
node1 ansible_host=192.168.0.2

角色/角色/默认值/main.yml

node1:
  if1: eth1
  ip1: 1.1.1.1/11

node2:
  if1: eth4
  ip1: 4.4.4.4/44

roles / role / tasks / main.yml

- name: test
  debug:
    msg: "{{ [inventory_hostname].[if1] }} end test  "

期望它在控制台上显示eth1，但显示错误

fatal: [node1]: FAILED! => {
    "msg": "The task includes an option with an undefined variable. The error was: 'if1' is undefined\n\nThe error appears to have been in '/root/ansible/roles/role/tasks/main.yml': line 6, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: test\n  ^ here\n"
}

Answer 1

您要寻找的是vars：

- name: test
  debug:
    msg: "{{ vars[ansible_hostname]['if1'] }} end test"

在库存查询中使用inventory_hostname
