Pythonic Microservices on AWS Lambda

Project Description

Psychic Disco

  • Are you a poor dope with a program to deploy?
  • Need to produce a demo, but haven’t yet hit pay dirt?
  • Love python development, but not product delivery?

Then let Psychic Disco be your principal delegate for publicly displaying your work!

By leveraging the pioneering domains of AWS Lambda and the Serverless Web, Psychic Disco allows even plebian dummies like you and I to scale the platforms of our dreams on the cheap.

Stinking Badges


Install like so:

pip install psychic_disco


  • All your microservices live in python modules
  • All your entrypoints are decorated with @lambda_entry_point

Declaring Entrypoints and API methods

Make a new entrypoint:

def handler(event, context):
  # important code here

Making a new api method automatically registers the entrypoint:

@api_method("POST", "/cereal"):
def create_cereal(event, context):
  # cereal creation logic here

Definitions for your API methods are available in psychic_disco.Api.

Discovering Entrypoints

Do this thing:

psychic_disco discover_entrypoints

Or, if your code lives elsewhere:

psychic_disco --repo path/to/st/elsewhere discover_entrypoints

Creating a Deployment Package

Do this thing:

psychic_disco bundle

That will make a virtualenv, install your dependencies, and zip it all up for you. This assumes that you have psychic_disco.config.default_s3_bucket defined in your

Deploying Lambda Functions

Once a deployment package has been uploaded to Amazon S3, you can install the lambda functions you defined like so:

psychic_disco deploy_lambdas

This assumes that you have psychic_disco.config.default_iam_role defined in your

Querying AWS

You can see what has already been configured on AWS by running:

psychic_disoc show_installed_routes <api-name>

Which will output something like:

verb path lambda-function
GET /users users-list_all
POST /users users-create_new
PATCH /user/7 users-update
