View source for Manual container creation

[[Category:Linux]]

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

 FROM debian:jessie
 MAINTAINER Paul Smith <p@ulsmith.net>
 LABEL Custom container
 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
 ENTRYPOINT ["/bootstrap/start.sh"]

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
