Quick Example for a Python Function (4 minutes)
This example will show you how to test and deploy Go (Golang) code to IronFunctions.
1. Prepare the functions.yaml file:
At functions.yaml you will find:
app: pythonapp
route: /hello
image: USERNAME/hello:0.0.1
build:
- docker run --rm -v "$PWD":/worker -w /worker iron/python:2-dev pip install -t packages -r requirements.txt
The important step here is to ensure you replace USERNAME with your Docker Hub account name. Some points of note:
the application name is pythonapp and the route for incoming requests is /hello. These informations are relevant for
the moment you try to test this function.
2. Build:
fnctl publish
-v is optional, but it allows you to see how this function is being built.
3. Queue jobs for your function
Now you can start jobs on your function. Let's quickly queue up a job to try it out.
cat hello.payload.json | fnctl run pythonapp /hello
Here's a curl example to show how easy it is to do in any language:
curl -H "Content-Type: application/json" -X POST -d @hello.payload.json http://localhost:8080/r/pythonapp/hello
