Franken crash

[XTalandier]

Hello,

I'm not sure if this is the right place to report this issue.

We have an automated build that runs every night. This morning, the builds and deployments completed successfully, but our app is crashing. There have been no code changes, just a simple build & deploy.

When I connect to the container, everything works correctly and I can execute PHP commands.

However, when we call our API, the server crashes completely https://pastebin.com/WNfQyTGY.

It seems that the frankenphp Docker image was updated this morning.

Help...

Can you copy your Dockerfile please?

Ok, we had the same issue on an internal project. This looks to affect only Alpine builds. Could you try to switch to Debian, please?
Alpine isn't supported officially by Symfony Docker anymore (but a fix would be appreciated if someone finds the underlying issue).

[XTalandier]

With this ?

FROM dunglas/frankenphp:1-php8.3 AS frankenphp_upstream

[dunglas]

Yes, and you also need to replace the RUN instruction using apk by this: https://github.com/dunglas/symfony-docker/blob/main/Dockerfile#L20-L25

[XTalandier]

ok it looks like all is good with that. Thank you !
