Deploying Bottle App with AWS

Question

I wanted to know how to deploy a app developed using bottle framework in AWS.

I created a EC2 instance, deployed the app in an environment - Linux Python 2.7 64 bit. I have the main file as application.py and run the framework using bottle.run(host='0.0.0.0")

I get following exception (error.log)

Can let me know where I'm going wrong.

Answer 1

As far as I now, you need to root access to bind to port 80. Try running it with

sudo ./application.py

Or you can change your port number to 8080 or similar.

If you are deploying this for production, I would suggest reading more on the bottlepy docs:

http://bottlepy.org/docs/dev/deployment.html#server-options

Hope it helps. Cheers.
