Я пытаюсь запустить bash-скрипт внутри функции GCP, но почему-то он не работает.Вот моя функция, которая в основном экспортирует файл (прокси) в Google Apigee:
def test2(request):
cmd = "python ./my-proxy/tools/deploy.py -n myProxy -u userName:!password -o myOrg -e test -d ./my-proxy -p /"
# no block, it start a sub process.
p = subprocess.Popen(cmd , shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
# and you can block util the cmd execute finish
p.wait()
# or stdout, stderr = p.communicate()
return "Proxy deployed to Apigee"
Вот мой deploy.py файл выглядит так:

Это работает, когда я запускаю локально намоя машина, но не на GCP.Не знаю, связано ли это с тем, что я подключаюсь к Google Apigee с помощью этой функции.Странно, что журналы на GCP не показывают ошибок, однако мой прокси не экспортируется в Apigee.
Спасибо за помощь!
ОБНОВЛЕНО: попытался использовать subprocess.check_output(), как поощряется некоторыми здесь:
def test(request):
output = None
try:
output = subprocess.check_output([
"./my-proxy/tools/deploy.py",
'-n', 'myProxy',
'-u', 'myUserName:myPassword',
'-o', 'myOrgName',
'-e', 'test',
'-d', './my-proxy',
'-p', '/'])
except:
print(output)
return output
И все еще не работает на GCP.Как я упоминал ранее, это работает как брелок (оба решения выше) на моей машине, но в GCP - нет.Как видно из изображения ниже, я получаю 200 после выполнения deploy.py из GCP, но мой файл не отправляется в Apigee:
Журналы GCP также не показывают ошибок:
