Overview

The dcm4chee module lets you use Puppet to install, deploy & configure dcm4chee and weasis.

Module Description

dcm4chee is an Open Source Clinical Image and Object Management system. http://www.dcm4che.org/

weasis is an Open Source DICOM web viewer. https://github.com/nroduit/Weasis

This module helps you in getting both set up and running using Puppet.

Following describes the basic building blocks executed by the module:

• staging
  • downloads and extracts all necessary archives for dcm4chee (dcm4chee, jboss, java image io library for 64bit machines, weasis) into a staging directory
  • executes install_jboss.sh to copy jboss components over to dcm4chee
  • exchanges a JAI Image IO library (libclib_jiio.so) for Linux-amd64 see dcm4chee install-guide
  • copies weasis, weasis-pacs-connector, weasis-i18n war files into dcm4chee's deployment directory
• installation
  • copies the dcm4chee home path prepared during staging to dcm4chee users home directory
  • installs a database server, creates a database for dcm4chee and executes the dcm4chee database creation script
• configuration
  • configures dcm4chee's database connection
  • configures jboss http and ajp ports and its java command line arguments
  • configures weasis using weasis pacs-connector
• service
  • sets up dcm4chee as a service via a template init.d script
  • ensures dcm4chee is running

Setup

Setup requirements

Please refer to the dependency section in metadata.json for the pre-requisite modules.

Important note: this module expects

• you to have java already installed
• you to have packages needed by nanliu-staging (such as unzip, curl) already installed

Beginning with dcm4chee

The simplest way to get dcm4chee up and running with the dcm4chee module is to install dcm4chee database and server on the same node as follows:

class { 'dcm4chee':
    server_java_path => '/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java',
}

Usage

Following describes basic use cases. Please check out the examples manifests as well.

I only want a default setup

To setup dcm4chee with its default settings do:

class { 'dcm4chee':
    server_java_path => '/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java',
}

I want to specify jboss java options

To specify jboss java options do:

class { 'dcm4chee':
    server_java_path => '/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java',
    server_java_opts => [ '-Xms128m',
                          '-Xmx740m',
                          '-XX:MaxPermSize=256m',
                          '-Dsun.rmi.dgc.client.gcInterval=3600000',
                          '-Dsun.rmi.dgc.server.gcInterval=3600000',
    ],
}

I want to specify jboss ports

To specify jboss ports other than the defaults do:

class { 'dcm4chee':
    server_java_path          => '/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java',
    server_http_port          => 8081,
    server_ajp_connector_port => 8089,
}

I want to install dcm4chee database and server on different nodes

To install dcm4chee database and server on separate nodes using roles and profiles pattern

node 'db.example.com' {
   include role::db
}

class role::db { 

   class { 'dcm4chee':
      server      => false,
      server_host => 'pacs.example.com', 
   }
}

node 'pacs.example.com' {
   include role::pacs
}

class role::pacs { 

   class { 'dcm4chee':
      server_java_path => '/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java',
      database         => false,
      database_host    => 'db.example.com',
   }
}

Note: you need to add necessary puppet code to above example code to ensure database connectivity between dcm4chee database and server.
