Webserver gives 500 Internal Server Error in Docker #21

netdjw · 2023-01-01T19:15:50Z

I try to use nlpserver in Docker, with this docker-compose.yml:

  nlp:
    build:
      context: ./.docker-config/dockerfiles
      dockerfile: nlpserver.dockerfile
    ports:
      - '6400:6400'
      - '9000:9000'
    volumes:
      - ./.docker-config/nlpserver/nlpserver.conf:/etc/supervisor/conf.d/nlpserver.conf
      - ./.docker-config/nlpserver/entrypoint.sh:/usr/local/bin/entrypoint.sh
    networks:
      - custom

This is the content of ./.docker-config/dockerfiles/nlpserver.dockerfile (I just made some small changes, because the original Dockerfile doesn't run)

# Use the official image as a parent image.
FROM python:3.8.5-slim-buster

RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y git && \
    apt-get install -y supervisor

# Set the working directory.

ENTRYPOINT ["/usr/local/bin/entrypoint.sh"]
 
EXPOSE 6400

This is the nlpserver.conf (not changed):

[program:nlpserver]
command=python3 /usr/src/nlpserver/nlpserver.py
directory=/usr/src/nlpserver/
autostart=true
autorestart=unexpected
stdout_logfile=/var/log/nlpserver.log
stderr_logfile=/var/log/nlpserver-error.log

This is the entrypoint.sh (not changed):

#!/bin/bash
/usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf
supervisorctl reread
supervisorctl update
supervisorctl start nlpserver

I made my custom NlpClient class in my Laravel app:

<?php

namespace Domain\AI\Clients;

use GuzzleHttp\Client;

class NlpClient
{
    private string $serverUrl = 'http://nlp:6400';

    public function post($uri = '', array $data = []): array
    {
        $client = new Client();

        $url = $this->serverUrl . $uri;

        $response = $client->request('POST', $url, [
            'json' => $data
        ]);

        $body = $response->getBody();

        $content = $body->getContents();

        $data = json_decode($content, true);

        return $data;
    }
}

...and add a service class with this function:

    public function summarize(string $text, int $word_count = 100)
    {
        $summary = $this->client->post(
            '/gensim/summarize',
            [
                'text' => $text,
                'word_count' => $word_count
            ]
        );

        return $summary ?? '';
    }

Finally I try to use this service like this:

    private function getSummary(): string
    {
        $nlpService = new NlpService();

        return $nlpService->summarize($this->post->content, 30);
    }

And the server said:

Server error: `POST http://nlp:6400/gensim/summarize` resulted in a `500 INTERNAL SERVER ERROR` response: <!doctype html>
 <html lang=en> <title>500 Internal Server Error</title> <h1>Internal Server Error</h1> <p>The server enc (truncated...)

After I logged into the container I found a log file where I see this:

[2023-01-01 19:03:27,758] ERROR in app: Exception on /gensim/summarize [POST]

172.19.0.7 - - [01/Jan/2023 19:03:27] "POST /gensim/summarize HTTP/1.1" 500 -

I don't know how to fix python code, so please help me to start the server!

Thank you!
