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, if you just want PHP with Apache httpd see the PHP image 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 arm32v5/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 -dit --name my-running-app -p 8080:80 my-apache2

Visit http://localhost:8080 and you will see It works!

Without a Dockerfile

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

$ docker run -dit --name my-apache-app -p 8080:80 -v "$PWD":/usr/local/apache2/htdocs/ arm32v5/httpd:2.4

Configuration

To customize the configuration of the httpd server, first obtain the upstream default configuration from the container:

$ docker run --rm arm32v5/httpd:2.4 cat /usr/local/apache2/conf/httpd.conf > my-httpd.conf

You can then COPY your custom configuration in as /usr/local/apache2/conf/httpd.conf:

FROM arm32v5/httpd:2.4
COPY ./my-httpd.conf /usr/local/apache2/conf/httpd.conf

SSL/HTTPS

If you want to run your web traffic over SSL, the simplest setup is to COPY or mount (-v) your server.crt and server.key into /usr/local/apache2/conf/ and then customize the /usr/local/apache2/conf/httpd.conf by removing the comment symbol from the following lines:

...
#LoadModule socache_shmcb_module modules/mod_socache_shmcb.so
...
#LoadModule ssl_module modules/mod_ssl.so
...
#Include conf/extra/httpd-ssl.conf
...

The conf/extra/httpd-ssl.conf configuration file will use the certificate files previously added and tell the daemon to also listen on port 443. Be sure to also add something like -p 443:443 to your docker run to forward the https port.

This could be accomplished with a sed line similar to the following:

RUN sed -i \
		-e 's/^#\(Include .*httpd-ssl.conf\)/\1/' \
		-e 's/^#\(LoadModule .*mod_ssl.so\)/\1/' \
		-e 's/^#\(LoadModule .*mod_socache_shmcb.so\)/\1/' \
		conf/httpd.conf

The previous steps should work well for development, but we recommend customizing your conf files for production, see httpd.apache.org for more information about SSL setup.
