Deploying Ghost blog container to Azure Linux app service - siteContainer x didn't respond to HTTP pings on port: 2368, failing site start

Question

I have a Ghost blog app running on Azure app service for linux via Azure Devops CI/CD, however i am getting and error "Container x didn't respond to HTTP pings on port: 2368". The ghost docker image uses port 2368 internally. I've looked at multiple other answers for example, setting the WEBSITE_PORT in the app service configuration to 2368 to no avail. I've turned my app to use always on. Stack trace below:

FROM ghost:4.11.0-alpine

# copy config.production.json, contains storage config.
COPY config.production.json config.production.json

# Add necessary packages for Sharp to work. The library installed below uses sharp to resize images.
RUN apk add --update --no-cache gcc g++ make libc6-compat python3

# Install Azure Storage adapter
RUN npm install ghost-storage-azure
RUN cp -vR node_modules/ghost-storage-azure current/core/server/adapters/storage/ghost-storage-azure

I've tried everything but i think it has to be something to do with the ports but not sure.
