The goal is to have a puppet module that is able to install tomcat in its basic form. So to remove the dependency from runit. Additionally we want to support multiple versions on 1 server, for this each tomcat instance will have its own full blown home directory. Also it would be nice to have the possibility to configure the ports so that multiple instance can run simultaneously. I'd like to build on this project of erwbgy because I like the idea of using the tarballs to create a setup.
Puppet module to install Apache Tomcat
The recommended usage is to place the configuration in hiera and just:
Example hiera config is included in the root of the repository.
If you use the puppet filestore, don't forget to stage your tarballs. The default tomcat naming scheme is used for the filenames.
basedir: The base installation directory. Default: '/opt/tomcat' this directory will hold the extracted tarball.
bind_address: The IP or hostname to bind listen ports to. Default: $fqdn
check_port: The port that the instance must be listening on (bound to bind_address) for it to be considered up. Default: '8080'
config: A hash of additional configuration variables that will be set when templates are processed.
dependencies: A list of Runit service directories whose services must be up before the Tomcat service is started.
cpu_affinity: Enable CPU affinity to be set to only run processes on specific CPU cores - for example '0,1' to only run processes on the first two cores.
files: A hash of configuration files to install - see below
filestore: The Puppet filestore location where the Tomcat tarball and Jolokia war file are downloaded from. Default: 'puppet:///files/tomcat'
gclog_enabled: Whether or not Garbage Collector logging is enabled. Default: 'false'
gclog_numfiles: The number of garbage collector log files to keep. Default: '5'
gclog_filesize: The maximum size of a garbage collector log file before it is rotated. Default: '100M'
group: The user''s primary group. Default: 'tomcat',
java_home: The base directory of the JDK installation to be used. Default: '/usr/java/latest'
java_opts: Additional java command-line options to pass to the startup script
jolokia: Whether or not to install the jolokia war file and configure a separate service to run it. Default: false
jolokia_address: The address that the jolokia HTTP service listens on. Default: 'localhost'
jolokia_cron: Whether or not to install cron jobs to run the Jolokia JMX monitoring scripts every minute writing to local log files. Default: 'true'
jolokia_port: The port that the jolokia HTTP service listens on. Default: '8190'
jolokia_version: The version of the jolokia war file to download and install. Default: '1.1.1'
localhost: The localhost address to bind listen ports to. Default: 'localhost'
logdir: The base log directory. Default: '/var/logs/tomcat'
min_mem: The minimum heap size allocated by the JVM. Default: 1024m
max_mem: The maximum heap size allocated by the JVM. Default: 2048m
mode: The permissions to create files with (eg. 0444).
remove_docs: Whether or not to remove the Tomcat docs under webapps. Default: true
remove_examples: Whether or not to remove the Tomcat examples under webapps. Default: true
templates: A hash of templates. if an entry is placed for one of the templates, the passed template is used instead of the template supplied in modules. Each template in the templates directory can be replaced by creating an entry for the name.
ulimit_nofile: The maximum number of open file descriptors the java process is allowed. Default is '$(ulimit -H -n)' which sets the value to the hard limit in /etc/security/limits.conf (or equivalent) for the user.
version: The version of the product to install (eg. 7.0.37). Required.
workspace: A temporary directory to unpack install tarballs into. Default: '/root/tomcat'
title: The user the Tomcat instance runs as service_ensure: Can be either present (default) or "running". If it is present a service script is provisioned. If it is "running" then on each puppet run the service will be checked and if it is not running it will be started.
Plus all of the parameters specified in 'tomcat parameters' above
Files or templates for each of the Tomcat instances can be delivered via Puppet. The former are delivered as-is while the latter are processed as ERB templates before being delivered.
For example configuration could be delivered using for instances running as the tomcat1 and tomcat2 users with:
tomcat::config: admin_user: 'admin' admin_pass: 'admin' tomcat::files: conf/tomcat-users.xml: source: 'puppet:///files/tomcat/dev/context.xml' tomcat: tomcat1: config: admin_pass: 'tinstaafl' templates: conf/tomcat-users.xml: template: '/etc/puppet/templates/tomcat/dev1/tomcat-users.xml.erb' tomcat2: config: admin_pass: 'timtowtdi' templates: conf/tomcat-users.xml: template: '/etc/puppet/templates/tomcat/dev2/tomcat-users.xml.erb'
Values set at the tomcat level as set for all instances so both the tomcat1 and tomcat2 instance would get the same context.xml file. Each instance would get their own tomcat-users.xml file based on the template specified with instance variables (like basedir and logdir) and config variables (like admin_user and admin_pass above) substituted.
<user username="<%= @admin_user %>" password="<%= @admin_pass %>" roles="tomcat,manager-gui"/>
All files and templates are relative to the product installation. For example if the product installation is '/opt/tomcat/apache-tomcat-7.0.37' then the full path to the 'tomcat-users.xml' file would be '/opt/tomcat/apache-tomcat-7.0.37/conf/tomcat-users.xml'.
Note that the path specified by the 'template' parameter is on the Puppet master.
There are default templates for conf/server.xml to listen on the specified bind_address and for conf/logging.properties to use the specified logdir. These defaults are only used if the template is not specified using the templates configuration.
By default the product tar file (eg. 'apache-tomcat-7.0.55.tar.gz') is expected to be found under a 'tomcat' directory of the 'files' file store. For example if /etc/puppet/fileserver.conf has:
[files] path /var/lib/puppet/files
then put the tar file in /var/lib/puppet/files/tomcat. Any files specified with the 'files' parameter can also be placed in this directory.
This location can be changed by setting the 'filestore' parameter.
This module will create a fact called tomcat_instances that will report on the provided instances.

- Add engine attribute for tomcat class and tomcat instance. Adapt template so that if a jvmRoute is set in this engine hash that a jvmRoute is configured on the engine in server.xml
- Test version without dependency on basedir
- Basedir should not be managed by the module as this might be part of the OS
- Store access logs in log directory.
- Introduce parameter service_ensure for an instance.
- Make sure that server.xml.erb puts hash elements alphabetically so that the configuration files doesn't change on subsequent puppet runs (cause explained at https://projects.puppetlabs.com/issues/16266)
- Make sure that instance_dir parameter is correctly passed
- Test if /etc/facts is already defined before defining it
- Change log dir to not put tomcat behind it but to really take the given logdir.
- Change service script in order to use instance_dir to get process ID (otherwise it the status is not reported correctly when the tomcat is started from the symlinked location).
- Make sure that service script is created and removed depending on the ensure parameter
- Also manage this service
- Stop notifying the instance dir on each puppet run.
Provide facts tomcat_instances and tomcat status, for instances a template can be provided.
Provide tomcat instance parameter ensure
All templates can be overriden by a site module using the templates array
Removed the template class from the module
Cleaned up templates that were not validated and migrated from previous module
Fix staging of files
Make sure users and groups that are used in the hiera configuration get created by Puppet
Multiple instances of tomcat can be declared
