[🐛 BUG]: Basic example does not work

[suityou01]

No duplicates 🥲.

• I have searched for a similar issue in our bug tracker and didn't find any solutions.

What happened?

I followed the example

Version (rr --version)

2023.3.8

How to reproduce the issue?

Create a dockerfile like so

FROM ghcr.io/roadrunner-server/roadrunner:2023.3.8 AS roadrunner
FROM php:8.2-cli as phpbuild

RUN apt-get update && apt-get install -y \
    zip \
    iputils-ping

COPY --from=roadrunner /usr/bin/rr /usr/local/bin/rr

# Install composer
RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" \
    && php composer-setup.php \
    && php -r "unlink('composer-setup.php');" \
    && mv composer.phar /usr/local/bin/composer

# Install php dependencies
RUN docker-php-ext-install sockets

FROM phpbuild

WORKDIR "/app"

# USE THE RR
COPY .rr.yaml .
COPY worker.php .
COPY composer.json .

RUN composer install

EXPOSE 80

CMD rr serve -c .rr.yaml

Create an .rr.yaml file

version: '3'

rpc:
  listen: tcp://127.0.0.1:6001

server:
  command: "php worker.php"

http:
  address: "0.0.0.0:8080"

logs:
  level: error

Create a composer file

{
    "require": {
        "spiral/roadrunner-cli": "^2.6"
    }
}

Create a php file

<?php

use Spiral\RoadRunner;
use Nyholm\Psr7;

include "vendor/autoload.php";

$worker = RoadRunner\Worker::create();
$psrFactory = new Psr7\Factory\Psr17Factory();

$worker = new RoadRunner\Http\PSR7Worker($worker, $psrFactory, $psrFactory, $psrFactory);

while ($req = $worker->waitRequest()) {
    try {
        $rsp = new Psr7\Response();
        $rsp->getBody()->write('Hello world!');

        $worker->respond($rsp);
    } catch (\Throwable $e) {
        $worker->getWorker()->error((string)$e);
    }
}

Run it.

Relevant log output

handle_serve_command: Function call error:
	serve error from the plugin *http.Plugin stopping execution, error: static_pool_allocate_workers: WorkerAllocate: EOF

Hey @suityou01 👋
I think that you also need spiral/roadrunner-worker and spiral/roadrunner-http packages. You may try to execute a regular php command, like php worker.php and you'll see the reason of EOF error. Unfortunately, when starting child process and it exists on some initial error, there are no errors except just EOF.

Hi @rustatian thank you I will try this. The bug is in the documentation then?

[rustatian]

Probably. Please point me where did you find this example, and I'll double-check and fix it.

This fixed my issue. Thanks.

This fixed my issue. Thanks.

Cool 👍 I'll add missing packages to the README and enjoy RR ❤️
