How to build darkhttpd

Simply run make:

make

Serve /var/www/htdocs on the default port (80 if running as root, else 8080):

./darkhttpd /var/www/htdocs

Serve ~/public_html on port 8081:

./darkhttpd ~/public_html --port 8081

Only bind to one IP address (useful on multi-homed systems):

./darkhttpd ~/public_html --addr 192.168.0.1

Serve at most 4 simultaneous connections:

./darkhttpd ~/public_html --maxconn 4

Log accesses to a file:

./darkhttpd ~/public_html --log access.log

Chroot for extra security (you need root privs for chroot):

./darkhttpd /var/www/htdocs --chroot

Use default.htm instead of index.html:

./darkhttpd /var/www/htdocs --index default.htm

Add mimetypes - in this case, serve .dat files as text/plain:

$ cat extramime
text/plain  dat
$ ./darkhttpd /var/www/htdocs --mimetypes extramime

Drop privileges:

./darkhttpd /var/www/htdocs --uid www --gid www

Use acceptfilter (FreeBSD only):

kldload accf_http
./darkhttpd /var/www/htdocs --accf

Run in the background and create a pidfile:

./darkhttpd /var/www/htdocs --pidfile /var/run/httpd.pid --daemon

Web forward (301) requests for some hosts:

./darkhttpd /var/www/htdocs --forward example.com http://www.example.com \
  --forward secure.example.com https://www.example.com/secure

Web forward (301) requests for all hosts:

./darkhttpd /var/www/htdocs --forward example.com http://www.example.com \
  --forward-all http://catchall.example.com

Commandline options can be combined:

./darkhttpd ~/public_html --port 8080 --addr 127.0.0.1

To see a full list of commandline options, run darkhttpd without any arguments:

./darkhttpd

First, build the image.

docker build -t darkhttpd .

Then run using volumes for the served files and port mapping for access.

For example, the following would serve files from the current user's dev/mywebsite directory on http://localhost:8080/

docker run -p 8080:80 -v ~/dev/mywebsite:/var/www/htdocs:ro darkhttpd

Enjoy.
