Using Serverless Gateway and Serverless APIs

This example shows how to serve a Serverless API composed of many functions through our serverless gateway.

Requirements

This example uses:

• Python API Framework to deploy the functions.
• Serverless Gateway to deploy a serverless gateway container.

Testing with serverless offline for Python

In order to test your functions locally before deployment in serverless functions, you can install our python offline testing library with:

pip install -r requirements-dev.txt

Launch your functions locally:

python app.py

Test your local functions using curl:

curl localhost:8080/func_a
curl localhost:8080/func_b
curl localhost:8080/func_c

Gateway set-up

Deploy the serverless gateway as a container following the Serverless Gateway project instructions.

Make sure to export your gateway base URL (GATEWAY_HOST) and an authentication token (TOKEN)

Running

Deploy your serverless API

Deploy your functions and add them automatically as endpoints to your serverless gateway using:

pip install -r requirements.txt
scw-serverless deploy app.py --gateway-url https://${GATEWAY_HOST} --gateway-api-key ${TOKEN}

Check your endpoint has been added

You can use:

./scripts/list_gateway_endpoints.sh

Call your function via its route

You can use:

curl https://${GATEWAY_HOST}/<chosen_relative_path>

Delete your endpoint

You can use:

./scripts/delete_function_to_gateway.sh https://<function_domain_name> /<chosen_relative_path>
