Tutorial 1: PHP Function w/ Input (3 minutes)

This example will show you how to test and deploy PHP code to Oracle Functions. It will also demonstrate passing data in through stdin.

First, run the following commands:

# Initialize your function creating a func.yaml file
fn init <DOCKERHUB_USERNAME>/hello

# Test your function. 
# This will run inside a container exactly how it will on the server. It will also install and vendor dependencies from Gemfile
fn run

# Now try with an input
cat hello.payload.json | fn run

# Deploy your functions to the Oracle Functions server (default localhost:8080)
# This will create a route to your function as well
fn deploy myapp

Now call your function:

curl http://localhost:8080/r/myapp/hello

Or call from a browser: http://localhost:8080/r/myapp/hello

And now with the JSON input:

curl -H "Content-Type: application/json" -X POST -d @hello.payload.json http://localhost:8080/r/myapp/hello

That's it!

Note on Dependencies

name: USERNAME/hello
version: 0.0.1
path: /hello
build:
- docker run --rm -v "$PWD":/worker -w /worker funcy/php:dev composer install

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 | fn call phpapp /hello

In Review

  1. We piped JSON data into the function at the command line

    cat hello.payload.json | fn run
    
  2. We received our function input through stdin

    obj = JSON.parse(fs.readFileSync('/dev/stdin').toString())
    
  3. We wrote our output to stdout

    console.log
    
  4. We sent stderr to the server logs

    console.error
