Symfony Panther && Docker (Alpine) chrome keeps crashing

  chromium, docker, php, symfony, symfony-panther

Recently I’ve decided to check out the Symfony Panther HTTP Client. I thought it would be nice to integrate that for testing and things.

I did follow the documentation very carefully. I have registered its extension for PHP unit. I can create a Panther client after extending the Panther Test Case – no problem there.

Problem shows when I try to make an actual call. Let’s say:

$client = static::createPantherClient([ "--no-sandbox", "--headless", "window-size=1024,768"]);
$client->request('GET', '/mypage');

These options in the array – I was just trying things out, I thought it might help. The error I am getting is as follows:

1) AppTestsIntegrationContainerControllersContainerControllerTest::test_read_container_by_slug
FacebookWebDriverExceptionUnknownErrorException: unknown error: Chrome failed to start: exited abnormally.
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/lib/chromium/chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

I did look at the docs and SO for a solution but I can’t really find anything that would help me.

Does anyone know why this is happening?

This is my Dockerfile for PHP

FROM php:7.4.3-fpm-alpine

WORKDIR /srv/app/

RUN apk update
RUN echo "extension=pdo_mysql" >> /usr/local/etc/php/php.ini-development
RUN docker-php-ext-install -j$(nproc) pdo_mysql

# php-redis

RUN docker-php-source extract 
    && curl -L -o /tmp/redis.tar.gz$PHPREDIS_VERSION.tar.gz 
    && tar xfz /tmp/redis.tar.gz 
    && rm -r /tmp/redis.tar.gz 
    && mv phpredis-$PHPREDIS_VERSION /usr/src/php/ext/redis 
    && docker-php-ext-install redis 
    && docker-php-source delete

RUN apk add --no-cache 

ENV PANTHER_CHROME_DRIVER_BINARY /usr/lib/chromium/chromedriver

RUN docker-php-ext-install opcache
RUN curl -sS | php -- --install-dir=/usr/local/bin --filename=composer

COPY conf/opcache.ini /usr/local/etc/php/conf.d/opcache.ini
