Ansible任务的输出

Question

我正在使用命令hcloud在Hetzner中创建云服务器。我得到这样的输出：

changed: [localhost] => (item={'name': 'TEST-VARIABLES', 'server_type': 'cx11', 'os_image': 'ubuntu-20.04', 'server_labels': 'Name=test-server', 'server_location': 'hel1'}) => {
"ansible_loop_var": "item",
"changed": true,
"hcloud_server": {
"backup_window": "None",
"datacenter": "hel1-dc2",
"delete_protection": false,
"id": "19461514",
"image": "ubuntu-20.04",
"ipv4_address": "11.111.111.111",
"ipv6": "1a71:7f9:c011:0b09::/64",
"labels": {
"Name": "test-server"
},
"location": "hel1",
"name": "TEST-VARIABLES",
"placement_group": null,
"rebuild_protection": false,
"rescue_enabled": false,
"server_type": "cx11",
"status": "running"
},
"invocation": {
"module_args": {
"allow_deprecated_image": false,
"api_token": "VALUE_SPECIFIED_IN_NO_LOG_PARAMETER",
"backups": null,
"datacenter": null,
"delete_protection": null,
"endpoint": "https://api.SERVER.cloud/v1",
"firewalls": null,
"force": false,
"force_upgrade": false,
"id": null,
"image": "ubuntu-20.04",
"labels": {
"Name": "test-server"
},
"location": "hel1",
"name": "TEST-VARIABLES",
"placement_group": null,
"rebuild_protection": null,
"rescue_mode": null,
"server_type": "cx11",
"ssh_keys": null,
"state": "present",
"upgrade_disk": false,
"user_data": null,
"volumes": null
}
},
"item": {
"name": "TEST-VARIABLES",
"os_image": "ubuntu-20.04",
"server_labels": "Name=test-server",
"server_location": "hel1",
"server_type": "cx11"
},
"root_password": "DFLDJFLDFDLFKJDLFKJ"
}

我试图与"ipv4_address": "11.111.111.111",和"root_password": "DFLDJFLDFDLFKJDLFKJ"保持一致，但当我使用任务时：

---
- name: Create a basic server
hcloud_server:
api_token: "{{ token }}"
name: "{{ item.name }}"
server_type: "{{ item.server_type }}"
image: "{{ item.os_image }}"
labels: "{{ item.server_labels }}"
location: "{{ item.server_location }}"
state: present
register: server_info
with_items: "{{ server }}"
- name: Here IP
debug:
var: server_info.root_password

我得到错误：

TASK [/etc/ansible/roles/CREATE-server : Here IP.] *********************************************************************************************************
ok: [localhost] => {
"server_info.root_password": "VARIABLE IS NOT DEFINED!"
}

你能帮助我如何获得IP线路和密码线路，以便在下一个任务中使用它们吗(例如通过电子邮件发送(。谢谢

您注册了循环的内容，因此您的结果是一个列表(results(：

- name: display
debug:
msg: "ip: {{ item.hcloud_server.ipv4_address }} has password: {{ item.root_password }}" 
loop: "{{ server_info.results }}" 

结果：这里只声明了一个服务器，所以列表中只有一个项目会导致

"msg": "ip: 11.111.111.111 has password: DFDFDFDFDFDFDFDF"

如果你想限制记录的输出，你可以将loop_control参数添加到带有参数标签的循环中：

loop: "{{ server_info.results }}"
loop_control:
label: "{{ item.hcloud_server.ipv4_address }}"

如果你想加标签甚至空字符串，你可以放另一个注释：

loop: "{{ server_info.results }}"
loop_control:
label: "result"
