Docker image is too old

[Dhruvi-UrbanFP]

The docker image uses stretch which is really old and causing issues when trying to update + it fails to integrate other services such as gcloud integration. Here is a suggested dockerfile that I build and successfully ran the tests on, is it possible to update the image?

Thank you for your suggestion, I will address this on the next deploy that I'm preparing.
