问题：

想要使用ansible-playbook脚本创建一个以远程机器的IP命名的目录

错误的代码：# vim test.yml

---
- hosts: all
remote_user: root
vars:
collect_info: "/data/test/{{ansible_all_ipv4_addresses}}/" tasks:
- name: create IP directory
file:
name: "{{collect_info}}"
state: directory

# ls -l /data/test/
总用量
drwxr-xr-x root root 5月 : [u'192.168.37.135']

原因是：获取的格式不对

# ansible all -m setup -a "filter="ansible_all_ipv4_addresses""
127.0.0.1 | SUCCESS => {
"ansible_facts": {
"ansible_all_ipv4_addresses": [
"192.168.0.1"
]
},
"changed": false
}而 “ansible_default_ipv4”获取的格式则刚好可以使用

# ansible all -m setup -a "filter="ansible_default_ipv4""
127.0.0.1 | SUCCESS => {
"ansible_facts": {
"ansible_default_ipv4": {
"address": "192.168.0.1",
"alias": "ens19",
"broadcast": "192.168.0.255",
"gateway": "192.168.0.254",
"interface": "ens19",
"macaddress": "00:0c:29:39:2c:95",
"mtu": ,
"netmask": "255.255.255.0",
"network": "192.168.0.0",
"type": "ether"
}
},
"changed": false
}

正确的代码是：

---
- hosts: all
remote_user: root
vars:
collect_info: "/data/test/{{ansible_default_ipv4['address']}}/" tasks:
- name: create IP directory
file:
name: "{{collect_info}}"
state: directory

网上有些说方法是：{{ipv4_eth0['address']}}，但是我的机器setup获取到的数值中没有ipv4_eth0，所以在截取数值之前先确认一下ip地址位于哪个部分，然后再截取正确的数值。
