#Dockerized Tomcat

A simple dockerfile that show how to create a minimal version of Tomcat7 using Java7. It downloads Tomcat7 from Apache website and places it under /opt/tomcat folder

WARNING! Dockerfile.tomcat6 is an alternative, it is provided to install Tomcat6. To show the power of docker this is radically different form Tomcat7 Dockerfile.

Main differences:

• use an existing image having Ubuntu / Java 6
• install Tomcat from Ubuntu repositories
• allow to create a "tomcat6" user, an map to a user on host machine (this may be useful)

##Prerequisites

• Docker⁠
• Docker Compose⁠ (opt.)

Replace configuration files with yours. In particular modify tomcat-users.xml file which contains user/pwd for Tomcat Manager. Default credentials are:

admin/passoword

This project suppose that you create a Tomcat container. You can place your webapp *.war file in three way:

• via Tomcat Manager
• via -v parameter via command line docker run
• via docker-compose by editing docker-compose.yml file

##Examples

Build & Run: [docker-compose] docker-compose up -d

Building:

[docker-compose] docker-compose build
[traditional] docker build -t tomcat .

Running:

[docker-compose] docker-compose run -d tomcat
[traditional] docker run -v <webapp_local_path>:/opt/tomcat/webapps/webapp.war -p 8080:8080 --name tomcat1 tomcat

Running (con bash interattiva):

[docker-compose] docker-compose run tomcat
[traditional] docker run -v <webapp_local_path>:/opt/tomcat/webapps/webapp.war -p 8080:8080 --name tomcat1 -i -t tomcat /bin/bash

Stopping or removing running container:

[docker-compose] docker-compose stop
[docker-compose] docker-compose rm --force        
[traditional] docker rm -f tomcat1
