Nginx & Lua

Latest Nginx with LUA support based on AlmaLinux, Alpine Linux, Amazon Linux, Debian, Fedora, and Ubuntu.

💗 Support the Project 💗

This project is only maintained by one person, Fabio Cicerchia.
It started as a simple docker image, now it updates automatically periodically and provides support for multiple distro 😎
Maintaining a project is a very time consuming activity, especially when done alone 💪
I really want to make this project better and become super cool 🚀

If you'd like to support this open-source project I'll appreciate any kind of contribution.

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 Windows.

What is Lua?

Lua is a lightweight, high-level, multi-paradigm programming language designed primarily for embedded use in applications. Lua is cross-platform, since the interpreter of compiled bytecode is written in ANSI C, and Lua has a relatively simple C API to embed it into applications.

Why this repo and not OpenResty?

With this project you'll get a fresh nginx + lua version the day after (or even less than a day) of the release of a new nginx version!

	nginx-lua	OpenResty
nginx latest version	`1.25.4`	`1.25.x` (last tested: `1.25.3.1`)¹
AlmaLinux supported	✅	❌

¹ Note:

Between official nginx 1.25.3 (24 Oct 2023) and OpenResty compatibility for 1.25.3.1 (9 Jan 2024) have passed ~3 months, instead fabiocicerchia/nginx-lua took 2 days.
On previous OpenResty version 1.21.x: the whole mainline 1.23.x has been skipped, while fabiocicerchia/nginx-lua was providing the version.
On latest version 1.25.x: between the first nginx release (23 May 2023) and the first OpenResty one (9 Jan 2024) have passed ~8 months.

Typical Uses

Just to name a few:

Mashup'ing and processing outputs of various Nginx upstream outputs (proxy, drizzle, postgres, redis, memcached, and etc) in Lua,

doing arbitrarily complex access control and security checks in Lua before requests actually reach the upstream backends,

manipulating response headers in an arbitrary way (by Lua)

fetching backend information from external storage backends (like redis, memcached, mysql, postgresql) and use that information to choose which upstream backend to access on-the-fly,

coding up arbitrarily complex web applications in a content handler using synchronous but still non-blocking access to the database backends and other storage,

doing very complex URL dispatch in Lua at rewrite phase,

using Lua to implement advanced caching mechanism for Nginx's subrequests and arbitrary locations.

The possibilities are unlimited as the module allows bringing together various elements within Nginx as well as exposing the power of the Lua language to the user. The module provides the full flexibility of scripting while offering performance levels comparable with native C language programs both in terms of CPU time as well as memory footprint thanks to LuaJIT 2.x.

Other scripting language implementations typically struggle to match this performance level.

How to use this image

Hosting some simple static content

$ docker run --name some-nginx -v /some/content:/usr/share/nginx/html:ro -d fabiocicerchia/nginx-lua
[...OMITTED...]

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 fabiocicerchia/nginx-lua
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
[...OMITTED...]

Exposing external port

$ docker run --name some-nginx -d -p 8080:80 some-content-nginx
[...OMITTED...]

Then you can hit http://localhost:8080 or http://host-ip:8080 in your browser.

Complex configuration

$ docker run --name my-custom-nginx-container -v /host/path/nginx.conf:/etc/nginx/nginx.conf:ro -d fabiocicerchia/nginx-lua
[...OMITTED...]

For information on the syntax of the nginx configuration files, see the official documentation (specifically the Beginner's Guide). If you wish to adapt the default configuration, use something like the following to copy it from a running nginx container:

$ docker run --name tmp-nginx-container -d fabiocicerchia/nginx-lua
[...OMITTED...]
$ docker cp tmp-nginx-container:/etc/nginx/nginx.conf /host/path/nginx.conf
[...OMITTED...]
$ docker rm -f tmp-nginx-container
[...OMITTED...]

This can also be accomplished more cleanly using a simple Dockerfile (in /host/path/):

FROM fabiocicerchia/nginx-lua
COPY nginx.conf /etc/nginx/nginx.conf

If you add a custom CMD in the Dockerfile, be sure to include -g daemon off; in the CMD in order for nginx to stay in the foreground, so that Docker can track the process properly (otherwise your container will stop immediately after starting)! Then build the image with docker build -t custom-nginx . and run it as follows:

$ docker run --name my-custom-nginx-container -d custom-nginx
[...OMITTED...]

Using environment variables in nginx configuration (new in 1.19)

Out-of-the-box, nginx doesn't support environment variables inside most configuration blocks. But this image has a function, which will extract environment variables before nginx starts. Here is an example using docker-compose.yml:

web:
  image: fabiocicerchia/nginx-lua
  volumes:
    - ./templates:/etc/nginx/templates
  ports:
    - "8080:80"
  environment:
    - NGINX_HOST=foobar.com
    - NGINX_PORT=80

By default, this function reads template files in /etc/nginx/templates/*.template and outputs the result of executing envsubst to /etc/nginx/conf.d. So if you place templates/default.conf.template file, which contains variable references like this:

listen       ${NGINX_PORT};

outputs to /etc/nginx/conf.d/default.conf like this:

listen       80;

This behavior can be changed via the following environment variables:

NGINX_ENVSUBST_TEMPLATE_DIR
- A directory which contains template files (default: /etc/nginx/templates)
- When this directory doesn't exist, this function will do nothing about template processing.
NGINX_ENVSUBST_TEMPLATE_SUFFIX
- A suffix of template files (default: .template)
- This function only processes the files whose name ends with this suffix.
NGINX_ENVSUBST_OUTPUT_DIR
- A directory where the result of executing envsubst is output (default: /etc/nginx/conf.d)
- The output filename is the template filename with the suffix removed.
  - ex.) /etc/nginx/templates/default.conf.template will be output with the filename /etc/nginx/conf.d/default.conf.
- This directory must be writable by the user running a container.

Running nginx in read-only mode

To run nginx in read-only mode, you will need to mount a Docker volume to every location where nginx writes information. The default nginx configuration requires write access to /var/cache and /var/run. This can be easily accomplished by running nginx as follows:

$ docker run -d -p 80:80 --read-only -v $(pwd)/nginx-cache:/var/cache/nginx -v $(pwd)/nginx-pid:/var/run fabiocicerchia/nginx-lua
[...OMITTED...]

If you have a more advanced configuration that requires nginx to write to other locations, simply add more volume mounts to those locations.

Running nginx in debug mode

Images since version 1.19.3 come with nginx-debug binary that produces verbose output when using higher log levels. It can be used with simple CMD substitution:

$ docker run --name my-nginx -v /host/path/nginx.conf:/etc/nginx/nginx.conf:ro -d fabiocicerchia/nginx-lua nginx-debug -g 'daemon off;'
[...OMITTED...]

Similar configuration in docker-compose.yml may look like this:

web:
  image: fabiocicerchia/nginx-lua
  volumes:
    - ./nginx.conf:/etc/nginx/nginx.conf:ro
  command: [nginx-debug, '-g', 'daemon off;']

Entrypoint quiet logs

Since version 1.19.0, a verbose entrypoint was added. It provides information on what's happening during container startup. You can silence this output by setting environment variable NGINX_ENTRYPOINT_QUIET_LOGS:

$ docker run -d -e NGINX_ENTRYPOINT_QUIET_LOGS=1 fabiocicerchia/nginx-lua
[...OMITTED...]

User and group id

Since 1.17.0, both alpine- and debian-based images variants use the same user and group ids to drop the privileges for worker processes:

$ id
uid=101(nginx) gid=101(nginx) groups=101(nginx)

Running nginx as a non-root user

It is possible to run the image as a less privileged arbitrary UID/GID. This, however, requires modification of nginx configuration to use directories writeable by that specific UID/GID pair:

$ docker run -d -v $PWD/nginx.conf:/etc/nginx/nginx.conf fabiocicerchia/nginx-lua
[...OMITTED...]

where nginx.conf in the current directory should have the following directives re-defined:

pid        /tmp/nginx.pid;

And in the http context:

http {
    client_body_temp_path /tmp/client_temp;
    proxy_temp_path       /tmp/proxy_temp_path;
    fastcgi_temp_path     /tmp/fastcgi_temp;
    uwsgi_temp_path       /tmp/uwsgi_temp;
    scgi_temp_path        /tmp/scgi_temp;
...
}

Notes

The SIGQUIT signal will be sent to nginx to stop this container, to give it an opportunity to stop gracefully (i.e, finish processing active connections). The Docker default is SIGTERM, which immediately terminates active connections. Note that if your configuration listens on UNIX domain sockets, this means that you'll need to manually remove the socket file upon shutdown, due to nginx bug #753.

Run Container

$ docker run -it --rm -p 80:80 \
  --health-cmd='curl --fail http://example.com || exit 1' \
  --health-interval=30s \
  --health-timeout=3s \
  fabiocicerchia/nginx-lua:latest

Image Variants

`fabiocicerchia/nginx-lua:<version>`

The default Nginx + Lua + extra lua modules image. Uses Alpine Linux for base image.

`fabiocicerchia/nginx-lua:<version>-<distro>`

Provides Nginx + Lua + extra lua modules. Uses AlmaLinux, Alpine Linux, Amazon Linux, Debian, Fedora, Ubuntu for base image.

`fabiocicerchia/nginx-lua:<version>-<distro><version>`

Provides Nginx + Lua + extra lua modules. Uses pinned version for AlmaLinux, Alpine Linux, Amazon Linux, Debian, Fedora, Ubuntu for base image.

Custom Builds

If you need to extend the functionality of the existing image, you could build your own version using the following command. For the list of values do refer to the relative section.

$ docker build \
  --build-arg NGINX_BUILD_CONFIG=... \ # nginx build flags
  --build-arg BUILD_DEPS=... \ # packages needed for building phase
  --build-arg NGINX_BUILD_DEPS=... \ # packages needed for building phase by nginx
  --build-arg PKG_DEPS=... \ # packages available in final image
  -f $DOCKERFILE .
