Deployment to Google Cloud App Engine fails.

[OlexBeatable]

I tried to deploy my CMS app to the Google Cloud App Engine. I used custom environment with Dockerfile. I took the Dockerfile from documentation as a base (https://payloadcms.com/docs/production/deployment#docker) and edited it according to App Engine requirements. In the end of deployment, when the script do health check - it fails.
For a database I use MongoDB Atlas.

Here is the Dockerfile

# Use the base App Engine Docker image, based on Ubuntu 16.0.4.
FROM gcr.io/gcp-runtimes/ubuntu_16_0_4:latest as system

# Install updates and dependencies

    apt-get upgrade -y && \
    apt-get clean && \

    apt-get update && apt-get install -y -q yarn && \
    mkdir -p /opt/yarn/bin && \

If you believe this was an error, try adjusting the 'app_start_timeout_sec' setting in the 'readiness_check' section.

In addition I have a question how to properly specify a serverURL in payload.config.ts for production? I assume that health check fails because of it.
