Cloud Functions: How to upload a folder that contains images?

Question

I want to deploy a bot using Cloud Functions from Google Cloud Platform. My code is write in python, but I want to add a folder with a lot of images that my bot will tweet on twitter. I want to do that to make sure my bot will run 24/7, and add to Cloud Scheduler to schedule my tweets.

Is possible to upload the image folder there somehow?

I tried to upload all of my file in a .zip file and upload there, but it will fail to build. Alone just code is working fine. I use Google Developer Platform for some time but I never tried this.

Here are the errors from google cloud platform:

Answer 1

When you deploy your code on Cloud Functions, the code is taken, compiled and packaged in a container (with Buildpack) and deployed on Cloud Functions.

In your case, the code is not compiled, only packaged.

Your source code is kept in the container, but in a specific directory. I wrote an article with a sample in Golang but you can find where the statics files are stored: /workspace/src/

That will fix your issue, but I think you have a design issue. The static and unstructured data should be in your Cloud Functions. Cloud Storage is the perfect place for that, and it's a better and more scalable solution.
