I want to enable intl extension on lambda layer with CDK

[asato-imanishi]

I'm using bref to build Laravel + AWS Lambda app with AWS CDK instead of serverless framework.

Bref Layer Version: arn:aws:lambda:ap-northeast-1:209497400698:layer:php-81-fpm:22

And I want to enable intl extension on lambda layer with CDK.

With serverless framework environment, we should enable it according to below procedure. ( put php/conf.d/php.ini on project root.)
https://bref.sh/docs/environment/php.html#extensions-installed-but-disabled-by-default

But with CDK, I don't know how to enable it.

Note: I'm aware that other extra PHP extensions can be enabled according to below procedure.

You need to create a file in {PROJECT_ROOT}/php/conf.d/php.ini where you place extension=intl as documented here https://bref.sh/docs/environment/php.html#extensions-installed-but-disabled-by-default

Thank you!

I incorrectly put php/conf.d/php.ini on cdk/ directory.
It worked by putting it on laravel project's root directory ( codebase/ ) instead of cdk/ directory.

${cdk_project_root}
├── cdk
   ├── cdk.json
   ├── php/conf.d/php.ini // wrong
├── codebase (laravel's project)
   ├── php/conf.d/php.ini // correct

@deleugpn already answered your question but I wanted to let you know about https://github.com/brefphp/constructs

It's still in beta, but it might be useful eventually.

Thank you for let me know about it!
That's useful for knowing how to setup project with cdk and bref.

@mnapoli I have a similar issue where I'm getting the following warning:
Warning: PHP Startup: Unable to load dynamic library 'intl' (tried: /opt/lib/php/extensions/no-debug-non-zts-20210902/intl (/opt/lib/php/extensions/no-debug-non-zts-20210902/intl: cannot open shared object file: No such file or directory), /opt/lib/php/extensions/no-debug-non-zts-20210902/intl.so (/opt/lib/php/extensions/no-debug-non-zts-20210902/intl.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Any idea where I'm going wrong? I'm using docker images with the following Dockerfile:

@nicodemuz could you please open a separate discussion?

FYI it seems that you are using incompatible versions of bref images (no version = v2) and bref-extra (0.x is for bref v1). But let's discuss that in a new thread because this is not related to AWS CDK.

@mnapoli Thank you. I created a new thread: #1525
