# What is httpd?

The Apache HTTP Server, colloquially called Apache, is a Web server application
notable for playing a key role in the initial growth of the World Wide Web.
Originally based on the NCSA HTTPd server, development of Apache began in early
1995 after work on the NCSA code stalled. Apache quickly overtook NCSA HTTPd as
the dominant HTTP server, and has remained the most popular HTTP server in use
since April 1996.

# How to use this image.

This image only contains Apache httpd with the defaults from upstream.  There is
no PHP installed, but it should not be hard to extend. On the other hand, of you
just want PHP with Apache httpd see the [PHP
image](https://registry.hub.docker.com/_/php/) and look at the `-apache` tags.
If you want to run a simple HTML server, add a simple Dockerfile to your project
where `public-html/` is the directory containing all your HTML.

### Create a `Dockerfile` in your project

    FROM httpd:2.4
    COPY ./public-html/ /usr/local/apache2/htdocs/

Then, run the commands to build and run the Docker image:

    docker build -t my-apache2 .
    docker run -it --rm --name my-running-app my-apache2

### Without a `Dockerfile`

If you don't want to include a `Dockerfile` in your project, it is sufficient to
do the following:

    docker run -it --rm --name my-apache-app -v "$(pwd)":/usr/local/apache2/htdocs/ httpd:2.4

### Configuration

To customize the configuration of the httpd server, just `COPY` your custom
configuration in as `/usr/local/apache2/conf/httpd.conf`.

    FROM httpd:2.4
    COPY ./my-httpd.conf /usr/local/apache2/conf/httpd.conf
