Docker build success but page cannot open in browser?-CodePudding

I am trying to run symfony using docker. This is my dockerfile

# Dockerfile
FROM php:7.2-cli

RUN apt-get update -y && apt-get install -y libmcrypt-dev

ENV COMPOSER_ALLOW_SUPERUSER=1

# install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer \
    && composer --ansi --version --no-interaction

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer \
    && composer --ansi --version --no-interaction
RUN docker-php-ext-install pdo mbstring


WORKDIR /app
COPY . /app

# RUN composer install --no-scripts --no-autoloader --ansi --no-interaction

EXPOSE 8000
CMD php -S localhost:8000 -t public 0.0.0.0:8000

After I build and run $ docker run -it -p 8000:8000 symfony-tutorial I get following response

D:\docker_test\symfony-4-tutorial>docker run -it -p 8000:8000 symfony-tutorial
PHP 7.2.34 Development Server started at Wed Jan 11 16:40:32 2023

Press Ctrl-C to quit.

But on browser, its empty. This page isn’t workinglocalhost didn’t send any data. ERR_EMPTY_RESPONSE. There is nothing in source and network tab

CodePudding user response：

Your web server binds to localhost, which means that it'll only accept connections from inside the container.

You need to change

CMD php -S localhost:8000 -t public 0.0.0.0:8000

CMD php -S 0.0.0.0:8000 -t public 0.0.0.0:8000
