deploy web application using zappa

I was following the steps here: https://github.com/Miserlou/Zappa to try to deploy my web app to AWS.

My app is using flask as server side and it also uses flask to host client-side JavaScript, html and css files. I can successfully host it on my local machine and on a server machine (I used host="0.0.0.0" on the server and I also specified a port number).

All I need to do is to run python my_app.py. The client side sends requests to the server and the server will respond.

I tried to deploy with zappa, but the page loads to an empty one. I'm not sure where I did wrong. One thing is that there are external libraries needed for my python program, how do I install it when I deploy it to my AWS lambda?

You definitely need to install your external libraries locally first, and then Zappa will take care of uploading them as part of the zip file.

In other words:

  • virtualenv my_venv

  • source my_venv/bin/activate

  • pip install zappa flask django etc

  • then run a local webserver to test that your app works, e.g. flask run

  • zappa init

  • zappa deploy dev OR zappa update dev (if you've already run deploy)
