Multiple apps on same server and https

[back-2-95]

I was just wondering this scenario:

• I have one virtual server for my hobby projects < so more than one
• If I would have 1 FrankenPHP container running per project, I cannot expose 80+443 for all
• I need a proxy like Traefik for handling 80+443 and redirecting to project containers

So I would reckon that in this scenatio I cannot use FrankenPHP's automatic HTTPS certificates generation and renewal, right?

FrankenPHP is built on top of Caddy, which natively supports running multiple sites out of the box.

You don't have to use Docker to achieve this—FrankenPHP can be installed directly either by compiling it from source or via the provided .deb or .rpm packages.

Once installed, you can define multiple sites in the Caddyfile like so:

https://my-project1.com {
    root * /app/myproject1

    # Other directives...
}

https://my-project2.com {
    root * /app/myproject2

    # Other directives...
}

You can also configure the global frankenphp worker block at the top of the Caddyfile to reference workers used by the different sites if needed.

If you're using Docker, it should be possible to adapt the setup similarly—by extending the Docker image and mounting a custom Caddyfile that includes multiple site blocks.

Finally, if you'd rather use a reverse proxy in front of FrankenPHP, Caddy itself can act as a very capable reverse proxy as well!

Note: Caddy is responsible for handling HTTPS certificates (including automatic renewal) and this is the reason FrankenPHP benefits from built-in HTTPS support.

It is worth pointing out the only downside with a threaded model like FrankenPHP; just to be 100% transparent. Because it is all running in a single processs and not multiple processes like fpm, you cannot run different operating system users per app -- they all must share the same operating system user. @back-2-95 doesn't mention this as a requirement, but it inevitably will in these kinds of threads.

I'm not sure about that (run different operating system users) - I think I will have multiple FrankenPHP containers which are build with basically the original Dockerfile but just some difference on what PHP extensions are installed.
