Goodle Cloud Storage with S3 interoperability

[samuelems]

I'm tring to use Authentik with Google Cloud Storage via S3-compatible API (HMAC keys) but getting SignatureDoesNotMatch errors when upload a file.

Working solution with AWS CLI:

export AWS_REQUEST_CHECKSUM_CALCULATION='when_required'
export AWS_RESPONSE_CHECKSUM_VALIDATION='when_required'

With these set, uploads work fine.

Question: How can I configure these boto3 options in Authentik? I tried adding them as environment variables to the container but seems they're not being picked up by django-storages/boto3.

Thank you for your help
