Docker-compose.yaml issue

Docker Hub General
1

I have created my Dockerfile and docker-compose.yaml.
When I run the command:

docker-compose up -d

Everything is fine, This builds the image of laravel application and runs the container. The problem is that when I try to access the application through browser. I get nothing but blank white page.

But again if i run the command:

docker run -d -p 8000:40 myImage

My application runs smoothly, after accessing http://localhost:8000

My docker-compose.yaml file is like this:

version: ‘3.3’
services:
app:
build:
context: .
dockerfile: .docker/Dockerfile
image: ‘myImage’
ports:
- 8888:80
volumes:
- ./laravel-app:/var/www/html
db:
image: mysql:5.7
restart: always
ports:
- “3333:3306”
environment:
MYSQL_DATABASE: ‘laravel-app’
MYSQL_ALLOW_EMPTY_PASSWORD: 1
MYSQL_ROOT_PASSWORD: “”
volumes:
- ./laravel-app/db:/var/lib/mysql

My Dockerfile is like this:

FROM link-to-my-image

USER root

WORKDIR /var/www/html

RUN apt-get update && apt-get install -y
libpng-dev
zlib1g-dev
libxml2-dev
libzip-dev
libonig-dev
zip
curl
unzip
&& docker-php-ext-configure gd
&& docker-php-ext-install -j$(nproc) gd
&& docker-php-ext-install pdo_mysql
&& docker-php-ext-install mysqli
&& docker-php-ext-install zip
&& docker-php-source delete

COPY .docker/vhost.conf /etc/apache2/sites-available/000-default.conf

RUN curl -sS https://getcomposer.org/installer | php – --install-dir=/usr/local/bin --filename=composer

RUN chown -R www-data:www-data /var/www/html
&& a2enmod rewrite

docker-compose up -d (white page when I access: localhost:8888)
docker run -d -p 8000:40 myImage (works fine when I access: localhost:8000)

Next time you share commands, compose file content or dockerfile content, please wrap them in a code block (</> icon). This time I corrected it for you.

Anyway, the shared information does not add up. You publish a different container port in your docker run command than you do in your compose file and then use an unrelated port to say it is working smoothly… Please straighten out the inconsitencies in your post:

Also your Dockerfile has neither ENTRYPOINT, nor CMD declared, so I assume it inherits them from the your customized apache base image.
