Alpine nginx image with LUA support
Full Description

#NGINX with LUA support

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. It compiles nginx with lua from their sources.

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:/nginx/html:ro -d mzollneritsch/nginx_lua-alpine

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 /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 mzollneritsch/nginx_lua-alpine

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 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

Here is an example using docker-compose.yml:

  image: mzollneritsch/nginx_lua-alpine
  volumes:
   - ./mysite.template:/etc/nginx/conf.d/mysite.template
  ports:
   - "8080:80"
