[英]How to run python script from Ansible and pass variable from the python script to Ansible to use later?
[英]How to pass large json result from ansible play into python script
從Ansible劇本中將非常大的json結果傳遞到python腳本時,出現“參數列表過長”錯誤。
基本手冊是:
- name: "The Playbook"
hosts: "localhost"
tasks:
- name: "Get JSON from API"
uri:
url: "https://my.real.api.url.goes.here.com"
method: GET
return_content: yes
headers:
Content-Type: "application/json"
Authorization: "my api token goes here and works."
register: result
- name: Run Py script
command: python get_tenants.py {{ result }}
become: yes
become_user: root
register: pyout
我也嘗試將結果傳遞為:
{{ result | map(attribute='content') }}
它會將指針傳遞給地圖,但不會將地圖本身作為單個項目傳遞。
我也嘗試將結果傳遞為:
{{ result | map(attribute='content') | list }}
無論如何,我得到:
"failed": true, "msg": "[Errno 7] Argument list too long", "rc": 7
我如何將ansible中的大型JSON結果傳遞到python腳本中?
我的第一個想法是將結果保存到文件,然后在python腳本中使用該文件。 但是在我看來,必須有更好的方法...
如果您的腳本能夠讀取STDIN的輸入,請嘗試使用here文檔 :
- name: "The Playbook"
hosts: "localhost"
tasks:
- name: "Get JSON from API"
uri:
url: "https://my.real.api.url.goes.here.com"
method: GET
return_content: yes
headers:
Content-Type: "application/json"
Authorization: "my api token goes here and works."
register: result
- name: Run Py script
shell: |
python get_tenants.py <<EOF
"{{ result.content }}"
EOF
become: yes
become_user: root
register: pyout
