Is there a way to make a folder in /tmp while using google cloud functions?

Question

I needed to create two folders within /tmp folder in Google Cloud functions. I am using a library which requires the files to be in that format (they can't just all be in /tmp ).

I tried this - os.makedirs('tmp/test') but that gave the following error:

Function failed on loading user code. Error message: [Errno 30] Read-only file system: 'tmp'
Detailed stack trace:
Traceback (most recent call last):

File "/env/lib/python3.7/os.py", line 223, in makedirs
mkdir(name, mode)
OSError: [Errno 30] Read-only file system: 'tmp'

Any way I can solve this?

Using os.makedirs('tmp/test') will attempt to create a directory at /user_code/tmp/test , which is not writeable.

You'll want to use a leading slash to ensure that you're creating the directory at /tmp/test instead, which is the only writeable part of the filesystem.
