OPENFAAS PHP8 Template

This is a PHP 8.0 template for OpenFaaS, the serverless functions project.

Comes with PHP 8.0.5 and Composer 2. Templates are built using the latest minor version of the major release.

Modules (by default)
Core, date, libxml, openssl, pcre, sqlite3, zlib, ctype, curl, dom, fileinfo, filter, ftp, hash, iconv, json, mbstring, SPL, PDO, pdo_sqlite, session, posix, readline, Reflection, standard, SimpleXML, Phar, tokenizer, xml, xmlreader, xmlwriter, mysqlnd, sodium

Install:

cd <project-dir>
faas-cli template pull https://github.com/mattwithoos/openfaas-php8
faas-cli new <function-name> --lang php8

Note that faas-cli doesn't appear to keep a registry or cache of third-party templates, so running template pull will store the template in the immediate ./template dir. Move it, or, update your .yml if this doesn't suit.

In the near future I'll submit the template to the official repo, making the process easier.

Usage

You will find in the newly created directory my-function:

• src/Handler.php : entrypoint
• php-extension.sh : is for installing PHP extensions if needed
• composer.json : is for dependency management

Extra Extensions

If you need to install an extension, check out the src/php-extension.sh file;

You can also refer to the PHP Docker image documentation for additional instructions on the installation and configuration of extensions

Private Composer Auth

In some cases, you may need to use private composer repositories - using the faas-cli you can pass in a build argument during build, for example;

faas-cli build -f ./functions.yml \
  --build-arg COMPOSER_AUTH='{"bitbucket-oauth": {"bitbucket.org": {"consumer-key": "xxxxxxxx","consumer-secret": "xxxxxxx"}}}'

See more information here.

That way you can pass in tokens for Composer, if necessary, GitHub tokens to get around rate-limit issues.
