If you need to create a custom container image, adding your own packages, create a Dockerfile as follows: 

FROM debian:jessie
MAINTAINER Paul Smith <[email protected]>
LABEL Custom container
WORKDIR /home
WORKDIR project
RUN echo "deb http://ftp.de.debian.org/debian stretch main" >> /etc/apt/sources.list
RUN apt-get update && \
   apt-get -yq install \
       apache2 \
       php5 \
       libapache2-mod-php5 \
       curl \
       ca-certificates \
       php5-curl \
       php5-json \
       php5-odbc \
       php5-sqlite \
       php5-mysql \
       php5-mcrypt \
       python bash && \
   apt-get clean -y && \
   rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /var/cache/apt/archive/*.deb
RUN /usr/sbin/php5enmod mcrypt && a2enmod rewrite && mkdir /bootstrap
ADD site.conf /etc/apache2/sites-available/000-default.conf
ADD start.sh /bootstrap/start.sh
RUN chmod 755 /bootstrap/start.sh && chown -R www-data:www-data /var/www/html
EXPOSE 80
VOLUME /etc/apache2/sites-available
ENTRYPOINT ["/bootstrap/start.sh","param1"]

start.sh 

#!/bin/bash
source /etc/apache2/envvars
exec apache2 -D FOREGROUND

site.conf 

<VirtualHost *:80>
   ServerAdmin webmaster@localhost
   DocumentRoot /var/www/html
   <Directory /var/www/html>
       Options FollowSymLinks
       AllowOverride All
       Order allow,deny
       Allow from All
           Require all granted
   </Directory>
</VirtualHost>
 ServerName localhost
 ServerSignature Off
 ServerTokens Prod

The image based on Dockerfile file above can be generated by the command below 

docker image build -t container1 .

You can also run this container using the compose.yaml file below (which will build the image anyway): 

version: '2'
services:
  myproject:
    build: ./
    container_name: webserver
    restart: always
    networks:
      - docker-localhost
    ports:
      - 80:80
    volumes:
      - /data/site:/var/www/html
networks:
  docker-localhost:

If using the compose.yaml file above, the container can be executed using: 

docker-compose up -d
