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
