如何建立一个ansible库存

Question

我需要 ansible inventory 中的一些结构来做这样的事情：

我有多个地址（有不同的项目），每个地址都有多个队列（有不同的项目）我如何为此建立清单文件。

像这样：

addresses:
  - name: "a-address"
    type: "anycast"
    read_username: "read"
    read_password: "xxxxx"
    write_username: "write"
    write_password: "xxxx"
    - queue_name: "a-queue1"
      queue_type: xxxx
    - queue_name: "a_queue2"
      queue_type: xvx
  - name: "b-address"
    type: "multicast"
    read_username: "readb"
    read_password: "xxxxx"
    write_username: "writeb"
    write_password: "xxxx"
    - queue_name: "b-queue1"
      queue_type: xvx
    - queue_name: "b_que

我该怎么做以及我应该如何在 ansible 中完成这个过程？

Answer 1

问："如何构建库存文件？"

A：这是库存的YAML version。我添加了变量 queues 使其成为有效的 YAML

shell> cat hosts.yml
all:
  hosts:
    a-address:
      type: anycast
      read_username: read
      read_password: xxxxx
      write_username: write
      write_password: xxxx
      queues:
        - queue_name: a-queue1
          queue_type: xxxx
        - queue_name: a_queue2
          queue_type: xvx
    b-address:
      type: multicast
      read_username: readb
      read_password: xxxxx
      write_username: writeb
      write_password: xxxx
      queues:
        - queue_name: b-queue1
          queue_type: xxxx
        - queue_name: b_queue2
          queue_type: xvx

例如剧本

- hosts: all
  tasks:
    - debug:
        var: type

给出（删节）

ok: [a-address] => 
  type: anycast
ok: [b-address] => 
  type: multicast

问："在地址上循环，并在该循环内在队列上循环。"

A：下面的剧本

- hosts: localhost
  tasks:
    - include_vars: hosts.yml
    - debug:
        msg: "{{ item.0.key }} {{ item.1 }}"
      with_subelements:
        - "{{ all.hosts|dict2items }}"
        - value.queues

给出（删节）

msg: 'a-address {''queue_name'': ''a-queue1'', ''queue_type'': ''xxxx''}'
msg: 'a-address {''queue_name'': ''a_queue2'', ''queue_type'': ''xvx''}'
msg: 'b-address {''queue_name'': ''b-queue1'', ''queue_type'': ''xxxx''}'
msg: 'b-address {''queue_name'': ''b_queue2'', ''queue_type'': ''xvx''}'
