app.yaml

# Comments are created with "#" like python
runtime: python310
env: standard
instance_class: F1
runtime_config:  # The runtime_config setting is for App Engine flex only and isn't needed for App Engine Standard. You can safely remove it.
  python_version: 3


# If `entrypoint` is not defined in app.yaml, App Engine will look for an app called `app` in `main.py`.
# That entrypoint is like:
# entrypoint: gunicorn -b :$PORT main:app
# Not having a number before port means "-b 0.0.0.0:$PORT". This is different from "-b 127.0.0.1:$PORT" or "-b localhost:$PORT", which only works on the running computer
# In my projects, I put all the code in the src/ folder.
# The --chdir argument allows you to change the current working directory so the code works out of src/
# If you didn't use --chdir and did src.YerrabelliFlask:app then all subsequent internal imports would require "src."
# first as well
# entrypoint: gunicorn -b :$PORT --chdir src/ YerrabelliFlask:app  # One option, but cannot access folders (like 'data') in top level
# An alternative strategy is to just add src/ to the pythonpath. This allows access to src folder automatically plus any topic level folders.
entrypoint: gunicorn -t 30 -b :$PORT --log-level debug --pythonpath 'src/' TonometrySimulation:app  # Currently used entrypoint

# Note, you can also run it using PyCharm -> run, but there might be slight differences between running on terminal and running via PyCharm

# You can test the server locally by inputting the entrypoint code line into terminal (assuming 'pip install gunicorn' is already done)
# To run locally, the port variable needs to be defined: i.e. by
# export PORT=5000  # only needs to be done locally
# Then you can access the page by using "curl $URL" or via a web browser using the URLs:
# -Only on the same computer:
# http://localhost:5000/
# http://127.0.0.1:5000/
# -Only on any computer in the same LAN/wifi:
# http://10.0.0.191:5000/    # assuming 10.0.0.191 is the internal ip address of the running computer (it is of my macbook pro in Urbana, IL on 2021_07_03)
# -Works anywhere (except maybe inside the same LAN/wifi)
# http://73.168.79.211:5000/  # Note, wasn't successfully working when testing? # assuming 73.168.79.211 is the external ip address of my Urbana, IL apt, and port forwarding has been setup with the router
