Standalone app doesn't include vendors?

[bpolaszek]

Hello there,

I just gave a try to the standalone mode from a Symfony application, strictly following the documentation steps.
I properly copied the project to /tmp/my-prepared-app, ran composer install and composer dump-env within it, then created the Dockerfile and built the binary.
However, when running it with ./my-app php-server, it boots, but when I curl -i http://localhost, here's what I get:

HTTP/1.1 200 OK

So far I understood that when running ./my-app php-server, the underlying PHP code gets unpacked in a /tmp/frankenphp_ceeae2d8693f725a855fab941146bcc3 directory; however, when I head to it, it doesn't contain any vendor directory (as opposed to /tmp/my-prepared-app for which I double-checked), hence the error.

What did I miss? 🤔

(Compiled and ran on an Ubuntu 22.04 server)

Follow-up:
After further investigation, by comparing my own code against https://github.com/dunglas/frankenphp-demo

• The docs invites the user to execute the composer install part on the host before creating a Dockerfile, whereas this part is included in the demo's Dockerfile (meaning it will be executed by the container)
• So I tried doing this and built the Docker image again, unfortunately without success, even with --no-cache
• But I noticed that /tmp/frankenphp_ceeae2d8693f725a855fab941146bcc3 was still the unpack target when running the binary, so I assumed Docker didn't give a shit to the --no-cache directive
• What worked was actually to replace my-app by something else when building the binary 🤷 - which indeed resulted in a different unpack target directory.

So, at least it works, except I had to add --no-scripts to the composer line, because some scripts executed PHP code which rely on specific PHP extensions (intl for instance); however PHP extensions are to be installed afterwards 🤔 - how to solve this?
