StorageBackends not working with GoogleCloudStorage

[pimvandenbroek]

The Helm chart version

netbox-5.0.0-beta.132

Environment Versions

Kubernetes 1.29
GKE

Custom chart values

# Use Google Cloud Storage backend
storageBackend: storages.backends.gcloud.GoogleCloudStorage
# Provide the necessary configuration for GCS
storageConfig:
  GS_BUCKET_NAME: 'your-gcs-bucket-name'
  GOOGLE_APPLICATION_CREDENTIALS: '/path/to/your/credentials.json'

Current Behavior & Steps to Reproduce

• Create a storage bucket
• Create a serviceaccount
• Mount the serviceaccount in the deployment to '/path/to/your/credentials.json'
• Add the config above

When uploading a file, you'll get:

Expected Behavior

I expect that files were uploaded to GCS.

Multiple tests were done:

• Local test using export GOOGLE_APPLICATION_CREDENTIALS='/path/to/your/credentials.json', and then using google.cloud python package to upload a file. This worked fine
• Jumped into the netbox-pod, and did the same. This also worked fine
• Created a django app, purely for uploading a file to gcloud storage. I had to add GOOGLE_APPLICATION_CREDENTIALS instead of GS_CREDENTIALS. After that file upload worked perfectly.

When using GS_CREDENTIALS: service_account.Credentials.from_service_account_file('/path/to/credentials.json') I see this error:

This library only supports credentials from google-auth-library-python. See https://google-auth.readthedocs.io/en/latest/ for help on authentication with this library.

Thanks for filing this issue, @pimvandenbroek.

As far as I can understand from here, this is not related to the Helm chart per se, right? If so, I'd recommend opening a case to the related project, NetBox in that case, I guess.

I partially agree. I'm using the provided options given by the Helm-chart, which aren't working as intended. And of course I understand it is still in beta, but that's exactly why we're trying to help by submitting issues.

I'm currently unable to setup a complete working Netbox instance (that's why we chose the helm-chart). For now I will close this issue, until I have some time to properly setup a Netbox instance.
