What is Nginx?

logo

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..

Usage

Hosting some simple static content

docker run --name some-nginx -v /some/content:/usr/share/nginx/html:ro -d bandsintown/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 bandsintown/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 bandsintown/nginx

For information on the syntax of the Nginx configuration files, see the official documentation (specifically the Beginner's Guide).

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 bandsintown/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

Dynamic configuration with Consul

Sometimes, it might be necessary to change the Nginx configuration dynamically for example to add hosts to achieve load balancing.

The Alpine Base image bundle a DNS Resolver and Consul Template in order to achieve this goal. With Consul template it is easy to create a dynamic load balancer based on Nginx dynamic upstreams.

To enable Consul template you just have to set the Consul address:

docker run -e CONSUL_HTTP_ADDR=demo.consul.io bandsintown/nginx

Build

This project is configured as an automated build in Dockerhub.

Each branch give the related image tag.
