Lucee on Tomcat with nginx

Lucee application engine running on Apache Tomcat J2EE application server and nginx HTTP server.

Features

NGINX web server

• NGINX web server running with supervisord (to run both NGINX and Tomcat processes)

Java optisation tweaks

• Lucee 4's Java Agent for the JVM is enabled for better memory management of compiled CFML code.

• JVM is set to use /dev/urandom as an entropy source for secure random numbers to avoid blocking Tomcat on startup.

• Tomcat is configured to skip the default scanning of Jar files on startup, significantly improving startup time.

Optimised for single-site application

The default configuration serves a single application for any hostname on the listening port. Multiple applications can be supported by editing the server.xml in the Tomcat config.

Session management

The default session type in Lucee is "cfml". This often causes issues for Lucee servers running in Docker containers. If you use CFML sessions you should set the session type to "j2ee" in a Lucee configuration file or Application.cfc.

Using this image

Accessing the service

The default configuration has nginx listening on port 80 and Tomcat listening on port 8080 in the container.

This image exposes ports 80, 443 (in case you enable SSL in nginx), and 8080 to linked containers, however you must publish the ports if you wish to access them from the Docker host.

Accessing the Web admin

The Lucee admin URL is /lucee/admin/ from the exposed port. No admin passwords are set.

THIS IS NOT A SECURE CONFIGURATION FOR PRODUCTION ENVIRONMENTS! It is strongly recommended that you secure the container by:

• Changing the server password
• Using IP or URL filtering to restrict access to the Web admin
• Following recommended security practices such as the Lucee Lockdown Guide

Sample CFML page

The default webroot contains a simple "Hello world" index.cfm file which dumps the CFML server scope. This can be replaced with your own CFML code and assets in derived images.

Folder locations

Web root for default site: /var/www

Configuration folders:
