问题描述
我是Ansible的新手，在这里我创建了一个将CSV作为参数的模块，如下所示：但是它不断抛出错误，即找不到CSV_TEST.csv文件。我是否可以在ansible模块中以正确的方式创建它作为变量？
module.py
def main():
field = dict(
csv=dict(type='str',required=True)
)
result = dict(
changed=False,response='')
module = AnsibleModule(argument_spec=field)
csvFile = module.params['csv']
listFinal = list()
final = list()
if csvFile:
with open(csvFile,"r",newline='',encoding='utf-8-sig') as csvImport:
reader = csv.DictReader(csvImport)
for row in reader:
newDict = dict({
'name': row.get("Name"),'address': row.get("Address")
'val': row.get("Val")
})
listFinal.append(newDict)
if listFinal:
for entry in listFinal:
if entry.get("val") == "Incorrect":
name = entry.get('name')
add = entry.get('address')
update = f'set add {add} of {name}'
final.append(update)
result['final'] = final
module.exit_json(changed=False,Meta=result)
if __name__ == '__main__':
main()
Playbook.yml
---
- name: Test Variables with Ansible
hosts: localhost
vars:
x: 30
xName: "Sai"
gather_facts: false
become: false
tasks:
- name: Test Device Validation
portDescription:
csv: CSV_TEST.csv
register: result
- debug: var=result
错误是：
***
FileNotFoundError: [Errno 2] No such file or directory: 'CSV_TEST.csv'
fatal: [localhost]: Failed! => {
"changed": false,"module_stderr": "Shared connection to localhost closed.\r\n",***
有人可以建议我在这里做错什么吗？ CSV_TEST.csv与Playbook.yml位于同一树形结构（父文件夹）下
解决方法
我认为，如果您在Ansible中有一个相对的文件路径，则Ansible首先会在本地目录中查找（如果您从ansible运行则输出该目录），然后它将在其他位置查找（请查看{ {3}}，以获取更多信息。
所以在我看来，您的目录结构就像
WorkingDir
|- playbook.yml
|- Ansible
|- CSV_TEST.csv
我认为您在ansible-playbook playbook.yml内部像WorkingDir一样运行ansible。它找不到CSV_TEST.csv，因为它在WorkingDir中寻找。
如果在python内部，您必须放置Ansible/CSV_TEST.csv到您的剧本中。所以
Ansible/CSV_TEST.csv如果这无济于事，那么您能以文本格式写出目录结构并显示所有内容从何处执行以及python在何处运行（---
- name: Test Variables with Ansible
hosts: localhost
vars:
x: 30
xName: "Sai"
gather_facts: false
become: false
tasks:
- name: Test Device Validation
portDescription:
csv: Ansible/CSV_TEST.csv
register: result
- debug: var=result
输出什么）？
一旦我修正了以上评论中报告的问题，您的代码就不会再出现其他问题。可能存在逻辑问题（但我不知道确切的期望是什么）。目前，这是一个证明运行，它可以按照我在您的模块代码中可以读取的预期运行。下面的路径都与我从中启动剧本的当前工作目录有关。
存储在./library/port_description.py
#!/usr/bin/python
from ansible.module_utils.basic import *
import csv
def main():
field = dict(
csv=dict(type='str',required=True)
)
result = dict(
changed=False,response='')
module = AnsibleModule(argument_spec=field)
csvFile = module.params['csv']
listFinal = list()
final = list()
if csvFile:
with open(csvFile,"r",newline='',encoding='utf-8-sig') as csvImport:
module.debug("csv openned")
reader = csv.DictReader(csvImport)
for row in reader:
newDict = dict({
'name': row.get("Name"),'address': row.get("Address"),'val': row.get("Val")
})
listFinal.append(newDict)
if listFinal:
for entry in listFinal:
if entry.get("val") == "Incorrect":
name = entry.get('name')
add = entry.get('address')
update = f'set add {add} of {name}'
final.append(update)
result['final'] = final
module.exit_json(changed=False,meta=result)
if __name__ == '__main__':
main()
存储在./CSV_TEST.csv中的csv文件（试图创建与预期名称和python代码对齐的文件...）
Name,Address,Val
toto,127.0.0.1,3
titi,192.168.0.1,Incorrect
该剧本存储在./test.yml
