# What is Nginx?
|
|
|
|
Nginx (pronounced "engine-x") is an open source reverse proxy server for HTTP,
|
|
HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer, HTTP cache,
|
|
and a web server (origin server). The nginx project started with a strong focus
|
|
on high concurrency, high performance and low memory usage. It is licensed under
|
|
the 2-clause BSD-like license and it runs on Linux, BSD variants, Mac OS X,
|
|
Solaris, AIX, HP-UX, as well as on other *nix flavors. It also has a proof of
|
|
concept port for Microsoft Window..

# How to use this image
|
|
|
|
## hosting some simple static content
|
|
|
|
docker run --name some-nginx -v /some/content:/usr/share/nginx/html:ro -d nginx
|
|
|
|
Alternatively, a simple `Dockerfile` can be used to generate a new image that
|
|
includes the necessary content (which is a much cleaner solution than the bind
|
|
mount above):
|
|
|
|
FROM nginx
|
|
COPY static-html-directory /usr/share/nginx/html
|
|
|
|
Place this file in the same directory as your directory of content
|
|
("static-html-directory"), run `docker build -t some-content-nginx .`, then
|
|
start your container:
|
|
|
|
docker run --name some-nginx -d some-content-nginx
|
|
|
|
## exposing the port
|
|
|
|
docker run --name some-nginx -d -p 8080:80 some-content-nginx
|
|
|
|
Then you can hit `http://localhost:8080` or `http://host-ip:8080` in your
|
|
browser.
|
|
|
|
## complex configuration
|
|
|
|
docker run --name some-nginx -v /some/nginx.conf:/etc/nginx/nginx.conf:ro -d nginx
|
|
|
|
For information on the syntax of the Nginx configuration files, see [the
|
|
official documentation](http://nginx.org/en/docs/) (specifically the [Beginner's
|
|
Guide](http://nginx.org/en/docs/beginners_guide.html#conf_structure)).
|
|
|
|
Be sure to include `daemon off;` in your custom configuration to ensure that
|
|
Nginx stays in the foreground so that Docker can track the process properly
|
|
(otherwise your container will stop immediately after starting)!
|
|
|
|
If you wish to adapt the default configuration, use something like the following
|
|
to copy it from a running Nginx container:
|
|
|
|
docker cp some-nginx:/etc/nginx/nginx.conf /some/nginx.conf
|
|
|
|
As above, this can also be accomplished more cleanly using a simple
|
|
`Dockerfile`:
|
|
|
|
FROM nginx
|
|
COPY nginx.conf /etc/nginx/nginx.conf
|
|
|
|
Then, build with `docker build -t some-custom-nginx .` and run:
|
|
|
|
docker run --name some-nginx -d some-custom-nginx
