如果我在剧本中使用 set_fact 和 if-else 语句,我会收到以下错误。
FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'hostname'. 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'hostname'\n\nThe error appears to be in '/runner/project/playbooks/Stack_Status.yml': line 148, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Write report data\n ^ here\n"}
有问题的代码在这里:
- name: Set final stack version fact
set_fact:
stack_version: >
{% if composer_stack is defined and composer_stack != 'Stack not deployed' %}
{{ composer_stack }}
{% elif fleet_agent_stack is defined and fleet_agent_stack != 'Stack not deployed' %}
{{ fleet_agent_stack }}
{% else %}
V3 Stack not deployed
{% endif %}
- name: Gather server report
set_fact:
server_report: >
{
"hostname": "{{ inventory_hostname }}",
"stack_version": "{{ stack_version | default('N/A') }}"
}
name: Write report data
shell: |
echo "\"{{ server_report.hostname }}\",\"{{ server_report.stack_version }}\"" >> "{{ report_file }}"
我希望显示 Composer 的版本(如果正在运行),或者打印 Fleet-Manager 的版本,但两者都没有运行显示,Stack 未部署。

错误消息已经说明了
AnsibleUnsafeText object' has no attribute 'hostname'
字符串对象不是字典,因为使用
set_fact: server_report
任务创建了包含 YAML 内容的字符串。最小的示例手册
---
- hosts: localhost
become: false
gather_facts: false
tasks:
- set_fact:
stack_version: >
{% if composer_stack is defined and composer_stack != 'Stack not deployed' %}
{{ composer_stack }}
{% elif fleet_agent_stack is defined and fleet_agent_stack != 'Stack not deployed' %}
{{ fleet_agent_stack }}
{% else %}
V3 Stack not deployed
{% endif %}
- set_fact:
server_report: >
{
"hostname": "{{ inventory_hostname }}",
"stack_version": "{{ stack_version | default('N/A') }}"
}
- name: Content of variable is
debug:
var: server_report | type_debug
- name: Whereby it should be
debug:
var: server_report | from_yaml | type_debug
- name: Now it is working
debug:
msg: "{{ ( server_report | from_yaml ).hostname | trim }}"
将产生
的输出PLAY [localhost] *****************************
