Install zip module on php 8.2 amazon linux elastic beanstalk

Question

I'm pretty sure the zip extension was included by default in the amazon managed php elb image.

The usual way to do this was adding a config file like this to .ebextensions

packages:
    yum:
        php-zip70: []

However that doesn't work anymore.

Any ideas?

Answer 1

@asdfasdfsdfga gave some good hints. A more modern approach:

Add the file .platform/hooks/prebuild/install-php-zip.sh

#!/usr/bin/env bash

yum -y install libzip libzip-devel

# Will enable zip extension in /etc/php.ini
pecl upgrade zip 

Note that "pecl install zip" will return an error code if already installed (?!), resulting in your deployment failing the second time you attempt to deploy. Instead, use upgrade, which will install if not already installed, and complete successfully if already installed.

The pecl command will insert 'extension="zip.so"' at the top of /etc/php.ini.

Answer 2

This is the solution I ended up with.

if test returns true then run command

files:
  "/etc/php.d/20-zip.ini":
    mode: "000644"
    owner: root
    group: root
    content: |
      extension=zip.so
commands:
  01_install_libzip:
    command: "dnf -y install libzip libzip-devel"
  02_install_zip:
    test: "php -r \"exit(extension_loaded('zip') ? 1 : 0);\""
    command: "pecl install zip"
