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 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.
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 -dit --name my-running-app my-apache2
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 -v "$PWD":/usr/local/apache2/htdocs/ httpd:2.4
To customize the configuration of the httpd server, just
COPY your custom configuration in as
FROM httpd:2.4 COPY ./my-httpd.conf /usr/local/apache2/conf/httpd.conf
If you want to run your web traffic over SSL, the simplest setup is to
COPY or mount (
/usr/local/apache2/conf/ and then customize the
/usr/local/apache2/conf/httpd.conf by removing the comment from the line with
#Include conf/extra/httpd-ssl.conf. This config 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.
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.
httpd images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
This image is based on the popular Alpine Linux project, available in the
alpine official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
To minimize image size, it's uncommon for additional related tools (such as
bash) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the
alpine image description for examples of how to install packages if you are unfamiliar).

Do you guys have any idea how I will be able to active http/2 on this image?
Similar to arjanpetersen, I'm getting "/usr/local/bin/httpd-foreground: 7: exec: httpd: not found" when attempting to run the httpd image. Has anyone else run into this issue?
Using docker-compose and I get
Sun Nov 13 23:43:50.304823 2016] [core:error] [pid 8:tid 140191667947264] (13)Permission denied: [client 192.168.99.1:61459] AH00132: file permissions deny server access: /usr/local/apache2/htdocs/img/decibel.png, referer: http://192.168.99.100/?
Why would I get that?
I set the port to 5000, however now the person has to come to port 5000?
Of course no one would ever type that, so how can the site be hit without the 5000 port being typed in at the end of the URL?
Thanks for your help!
Hi, I used the dockerfile in the 2.4 directory on the github repository. After building the image - I get
arjan@osboxes:~/mydockerbuild$ docker run -it --rm --name my-running-app my-apache2
docker: Error response from daemon: Container command 'httpd-foreground' not found or does not exist..
When tryring to run the image. Any thoughts. Or should I just stick to commands above?
I am trying to use ProxyHTMLURLMap and I found out that this image does not have mod_proxy_html.so installed. I found references on how to install it but it seem to require libxml2.so which is also not included on this image.
Does anyone have an idea on how to install this module properly? Thanks.
I tried to install php on this image, but the debian image seems to use a different installation path for apache, so the apache PHP module was installed under:
LoadModule php5_module /usr/lib/apache2/modules/libphp5.so
There were also separate apache configs installed under /etc/httpd whereas apache was installed under
after the following error I gave up trying to get this apache docker image to work:
root@piwik2-v1:/usr/local/apache2/conf# apachectl -M

You need to recompile PHP.

Maybe it would be better to create the apache docker image by installing the apache distributed with the offical debian OS image?
I'm off to try out the official PHP docker image now, to see if that works OK!
i am trying to set AEM dispatcher using the HTTP docker image.
I am facing issues when loading shared object files (.so) and getting the below error. Please can anyone help?
httpd: Syntax error on line 153 of /usr/local/apache2/conf/httpd.conf: Cannot load modules/mod_dispatcher.so into server: /usr/local/apache2/modules/mod_dispatcher.so: invalid ELF header
No issues with the SO file as it is directly downloaded from AEM site.
I had issues in placing the .so file on the image and container. I managed to download all the modules from container and placed it in local along with the dispatcher.so. On the run command, i have mounted the local volume to the modules dir. All modules are loading fine but the dispatcher module is giving this error.
Any thoughts in placing and loading ".so" file in the container?
i can copy the customised http.conf file successfully.
Thanks & Regards,
my docker file -
