Package and deploy code to a runtime and make it run as expected - Function Compute

This topic uses a third-party dependency Nette\Utils as an example to describe how to install dependencies for your PHP code, package and deploy code to Function Compute.

Preparations

Create a code directory for tests and specify a name for the directory. In this example, mycode is used.
- Linux and macOS
  Run the mkdir -p /tmp/mycode command to create the directory.
- Windows
  Create a folder and name it mycode.

In the mycode directory, create the index.php file.

The following code describes the content of the file:

<?php

require_once __DIR__ . '/vendor/autoload.php';

use Nette\Utils\Arrays;

function handler($event, $context) {
    return Arrays::contains([1, 2, 3], 1);
}

Use Composer to install dependencies and deploy the code package

Prerequisites

PHP and Composer are installed on your machine. You have the permissions to execute Composer commands. For more information about Composer, see Composer.
(Optional) A PHP function is created in the Function Compute console. For more information, see Create a function.

Procedure

Create the composer.json file in the mycode directory.
The following code shows the content of the file:
```
{
  "require": {
    "nette/utils": "v3.2.5"
  }
}
```
Run the composer install command in the mycode directory to install dependencies.
After the execution is complete, the composer.lock file and the vendor directory are generated in this directory. The downloaded dependencies are stored in the vendor directory.
Package all files in the mycode directory.
- Linux and macOS
  Go to the mycode directory and run zip code.zip -r ./*.
  Note
  Make sure that you have the read and write permissions on the directory.
- Windows
  Go to the mycode directory, select all files, right-click the files, and then compress the files into a ZIP package.
Note
Make sure that the index.php file that you created is in the root directory of the package.
In the Function Compute console, find the function that you want to manage. In the upper-right corner of the function details page, click Upload Code and upload the .zip file that you prepared.
You can also upload a ZIP package when you create a function in the Function Compute console. For more information, see Create a function.
On the Code tab of the function details page, click Test Function.

Use Serverless Devs to install dependencies and deploy code

Before you start

Procedure

Edit the s.yaml file in the mycode directory.

The following sample code provides an example of the file:

edition: 3.0.0
name: fcDeployApp
access: "default"

vars: # Global variables
  region: "cn-hangzhou"

resources:
  hello_world:
    component: fc3 # The component name
    props:
      region: ${vars.region}              # For information about how to use variables, visit: https://docs.serverless-devs.com/serverless-devs/yaml#%E5%8F%98%E9%87%8F%E8%B5%8B%E5%80%BC.
      functionName: "testphp"
      description: 'this is a test'
      runtime: "php7.2"
      code: ./
      handler: index.handler
      memorySize: 128
      timeout: 30

In the mycode directory, add the composer.json file.
The following sample code provides an example of the file:
```
{
    "require": {
        "nette/utils": "^3.0"
    }
}
```
Run sudo s build --use-docker to install dependencies.
After the execution is complete, the dependencies and code are deployed to the ./vendor directory.
Run sudo s deploy to deploy the project.
After the execution, you can deploy your function to Function Compute.

More information

You can also use layers of Function Compute to install dependencies. For more information, see Create a custom layer.
