bref.sh php container for AWS Lambda with Neos CMS

Question

I'm struggling to get Neos (a php based cms) to run in a docker container for AWS Lambda. I guess I have somewhere a misunderstanding and hope anyone can help.

What I did so far:

1. I adjusted Neos so that all cache files will be written to the tmp folder
2. I added the bref and extra-php-extensions package to composer.json
3. I created a docker file, quite simple as shown by Mattheu Naploli's blog article: https://mnapoli.fr/aws-lambda-php-docker-containers/
4. I have created a cloudformation template to use sam local start-api

Dockerfile:

FROM bref/php-74-fpm

COPY . /var/task

# Start Bref's runtime client
CMD _HANDLER=Web/index.php /opt/bootstrap

template.yml

Response of sam local start-api:

entrypoint requires the handler name to be the first argument
time="2021-04-14T22:11:48.093" level=error msg="Init failed" InvokeID= error="Runtime exited with error: exit status 142"
time="2021-04-14T22:11:48.093" level=error msg="INIT DONE failed: Runtime.ExitError"
Invalid lambda response received: Lambda response must be valid json

What I don't understand, I'd expect that there is always a valid json returned, even though the php delivers a 5xx error. I'm lost ... even though this wouldn't be the case, how can I debug the issue?

In the end, I have to create my own docker image as Neos is too big to use the bref layers and I need quite some php extensions. If I could understand the current issue, I can work through this and provide a working container for everyone.

I have a few more questions, in this scenario, were I have a web application and use a container, do I have to install the bref packages with composer? That wasn't clear in the blog post. Also do I have to set the Handler in serverless/sam and if so, which would be the correct string, given that Web/index.php is the path in Neos?

In general, Neos would work awesome in AWS. My setup would be:

1. CloudFront with behaviors for static files from S3 and everything else to lambda
2. Redis to store cache files from Neos
3. ElasticSearch for website search and improved performance on huge sites

As soon as this is working, I'll publish all information for free for the Neos community to get this working.

Hope someone can help...

Thank you!

Answer 1

Could you try this:

FROM bref/php-74-fpm

# Include any extension you want, for example:
#COPY --from=bref/extra-gd-php-74:0.9.5 /opt /opt

ADD . $LAMBDA_TASK_ROOT

CMD [ "index.php" ]

The format has been simplified since the article (see https://gist.github.com/mnapoli/f911a50c7aab77690e6cdde157812265).
