The goal is to always make these guides very simple - but to build from there, and to always try to include debugging information.
Prerequisites: If you need a quick startup script for installing docker / docker-ce:

- apache images are for serving static content.
- php images are for serving php code which can generate pages and also poll from databases for dataset presentations
Step 1: Apache Container Basics Calling a basic apache docker image and running it to see how it works.
docker run -it --name my-apache-app -p 8080:80 httpd:latest
![](https://www.hotconfig.com/content/images/2024/06/image-74.png)
- -it Interactive terminal mode
- --name name of running container
- -p 8080:80 port 8080 on host will map to port 80 on container
- httpd:latest the image to pull and run

- Naturally we have not mapped any data. Adding data and going into 'daemon' mode only requires changing your command line to the following
docker run -dit --name htttp -p 8080:80 -v /data:/usr/local/apache2/htdocs/ httpd:latest
- The pages root dir in a apache2 are served from /usr/local/apache2/htdocs/
- The pages root dir in otherapache server are served from /var/www/html
A docker-compose.yaml example:
version: '3'
services:
apache2:
image: httpd:latest
volumes:
- /data:/usr/local/apache2/htdocs/
ports:
- 8080:80
Which is then stood up with (diagnostic mode)
docker-compose up
Or in full continuance mode:
docker-compose up -d
Step 2: PHP Container Basics
- The process of standing up a php html server is identical, and will enable you to run and process php code along with serving content.
- The internal root is /var/www/html
Running in diagnostic mode:
docker run -it -p 8080:80 --name php_app -v /data:/var/www/html php:7.2-apache
- Running in permanent daemon mode one adds -d to above
Checking the capabilities of the php running container:
- Make a file in the /data named index.php:
<?php
phpinfo();
phpinfo(INFO_MODULES);
?>
And then call it with:
http://<local ip>/index.php
It will show up as (if it is working)

Docker-compose.yaml example:
version: '3.1'
services:
php:
image: php:7.2-apache
ports:
- 8080:80
volumes:
- /data:/var/www/html/
