Dockerfile PHP, NGINX and Composer - dockerfile

Question

I'm having a difficult time finding resources for creating a Dockerfile to install a proper PHP, Composer and NGINX environment.
I can create a docker-compose container set, but I cannot get composer installed doing that. If anyone has any good resources to point me to, in order to write a full PHP, Composer and NGINX Dockerfile.

Answer 1

this is my docker file example for a similar scenario, I hope it helps. Feedback and ideas are welcomed !
FROM php:7.4-fpm
# Install system dependencies
RUN apt-get update && apt-get install -y \
git \
curl \
libpng-dev \
libonig-dev \
libxml2-dev \
libzip-dev \
zip \
unzip \
software-properties-common \
lsb-release \
apt-transport-https \
ca-certificates \
wget \
gnupg2
# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*
# Install PHP extensions (some are already compiled in the PHP base image)
RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd json zip xml
# Get latest Composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer
# Create myuser
RUN useradd -G www-data,root -u 1000 -d /home/myuser myuser
RUN mkdir -p /home/myuser/.composer && \
chown -R myuser:myuser /home/myuser
# Set working directory
WORKDIR /var/www/mypage
USER $user
You can add nginx to this container but then, I recommend to use supervisord to control multiple processes.
