This docker image based on Debian Stretch linux distribution. Project goal is an easy to build docker image of latest Nginx web server with Google PageSpeed and Geo IP modules.

The PageSpeed tools analyze and optimize your site following web best practices. If turned ON it exposes a PageSpeed admin status page at:

• http://localhost:8080/pagespeed_admin/

The VTS Nginx virtual host traffic status module. It exposes a status page at:

• http://localhost:8080/status/

The GeoIP databases to help decode remote IP address into geographical location.

The [more_set_headers] (https://github.com/openresty/headers-more-nginx-module)allows to set more HTTP response headers - useful in multi cluster environments.

The subs_filter allows nginx to filter which can do both regular expression and fixed string substitutions on response bodies.

Container will produce web server access log through docker /stdout in json format for easy parsing via 3rd party containers like Fluentd.

Include environment variables to turn ON | OFF Page Speed optimization features for:

• images
• javascripts
• style sheets
• cache engine for cluster environments: files, memcached or redis

as well as:

• vhosts stats page
• default host with health check

Nginx is configured by default for high performance, multi cluster production environment, but can be easily adjusted with environment variables.

Example docker-compose.yml uses default environment variables:

MAKE_J=4
NGINX_VERSION=1.13.3
PAGESPEED_VERSION=1.12.34.2
LIBPNG_VERSION=1.6.29

NGINX_DEFAULT_SERVER=on
