Deploying Haskell yesod docker container on google app engine

I am trying to upload a yesod Docker container on Google App Engine. The source code is here and the Docker image is here.

I followed the documentation in the Custom runtime quickstart, and when invoking gcloud app deploy the app builds fine after increasing the build timeout, but the container either the readiness check when trying to start or shows the following timeout message:

ERROR: (gcloud.app.deploy) Operation [apps/meeshkan-github-webhook-router/operations/xxxx-xxxx-xxxx] timed out. This operation may still be underway.

I have tried experimenting with several things, including a manual readiness check, creating an /_ah/health endpoint, and increasing the timeout of the readiness check all the way to 1799 seconds, but none of these actions seem to work.

One issue may be the size of the container (it is 3.2gb), and I could try to prune it down, but I'd only do that if someone could confirm that container size is a contributing factor to deployment problems. Other than that, I'm not sure what could be causing this failure. The docker image starts fine on our local machines.

Thanks in advance for your help and suggestions!

The issue turned out to be that, because I was building on Windows, images built using Docker Desktop on Windows gave all shell scripts executable permission automatically, whereas Docker on Linux needs shell scripts to be given the executable permission. By adding this line to my Dockerfile:

RUN chmod +x /usr/src/app/run.sh

Everything worked fine!
