all:

基本上，我有一个接入交换机，并且有许多组交换机已经连接到it...Tried“孩子”，但这不起作用。典型的ini文件可以工作...此外，我有一些variables...which确实适用于所有区域，又名。访问交换机和组开关...未来将有超过1台..multiple接入交换机。……有些文档使用ansible-host：...令人困惑..

和yes..checked的uml结构...

cat@catwomen:~/workspace/ansible-simulator/inventories/simulator/host_vars$ sudo ansible -i testdata.yaml  all -m  ping 
 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match
'all'

cat@catwomen:~/workspace/ansible-simulator/inventories/simulator/host_vars$ sudo ansible -i testdata.yaml all -m  ping 
 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match
'all'

Answer 1

您有yaml缩进问题，这是一个错误( yaml中的缩进很重要)。此外，您必须遵循the specific format described in the documentation。

基本上，该文件是父/子关系中的组的叠加，从顶级元素特殊组all开始。组定义如下所示：

---
my_group1: # group name, use `all` at top level
  vars:
    # definition of vars for this group. Apply to all hosts if defined for `all`
  hosts:
    # hosts in that group (host is ungrouped if it appears only in `all`)
  children:
    # mapping of children group definitions (repeat the current format)

主机定义如下所示：

my_host1:
  # definition of vars specific to that host if any

var定义(针对组中的vars或针对特定主机)如下所示：

my_variable1: some value

如果我从您的示例中正确理解，以下是您的yaml清单应该是什么样子的(inventories/so_example.yml)

---
all:

  children:

    accessswitch:
      hosts:
        accessswitch-x0:
          ansible_host: 192.168.4.xx

    groupswitch:
      hosts:
        groupswitch-x1:
          ansible_host: 192.168.4.xx
        groupswitch-x2:
          ansible_host: 192.168.4.xx
        groupswitch-x3:
          ansible_host: 192.168.4.xx

然后，您可以很容易地看到上面的内容是如何用ansible-inventory command解释的

$ ansible-inventory -i inventories/so_example.yml --graph 
@all:
  |--@accessswitch:
  |  |--accessswitch-x0
  |--@groupswitch:
  |  |--groupswitch-x1
  |  |--groupswitch-x2
  |  |--groupswitch-x3
  |--@ungrouped:

$ ansible-inventory -i inventories/so_example.yml --list
{
    "_meta": {
        "hostvars": {
            "accessswitch-x0": {
                "ansible_host": "192.168.4.xx"
            },
            "groupswitch-x1": {
                "ansible_host": "192.168.4.xx"
            },
            "groupswitch-x2": {
                "ansible_host": "192.168.4.xx"
            },
            "groupswitch-x3": {
                "ansible_host": "192.168.4.xx"
            }
        }
    },
    "accessswitch": {
        "hosts": [
            "accessswitch-x0"
        ]
    },
    "all": {
        "children": [
            "accessswitch",
            "groupswitch",
            "ungrouped"
        ]
    },
    "groupswitch": {
        "hosts": [
            "groupswitch-x1",
            "groupswitch-x2",
            "groupswitch-x3"
        ]
    }
}

第6行的事件不正确。请在下面尝试。

all: 
zones:
  - name: accessswitch
    hosts:
    - name: accessswitch-x0
      ip: 192.168.4.xx

  - name: groupswitch
    hosts:
    - name: groupswitch-x1
      ip: 192.168.4.xx
    - name: groupswitch-x2
      ip: 192.168.4.xx
    - name: groupswitch-x3
