Overview

The tomcat module lets you use Puppet to install, deploy, and configure Tomcat web services.

Module Description

Tomcat is a Java web service provider. The tomcat module lets you use Puppet to install Tomcat, manage its configuration file, and deploy web apps to it. It supports multiple instances of Tomcat spanning multiple versions.

Setup

Requirements

The tomcat module requires puppetlabs-stdlib version 4.0 or newer. On Puppet Enterprise you must meet this requirement before installing the module. To update stdlib, run:

puppet module upgrade puppetlabs-stdlib

Beginning with tomcat

The simplest way to get Tomcat up and running with the tomcat module is to install the Tomcat source and start the service:

tomcat::install { '/opt/tomcat':
  source_url => 'https://www-us.apache.org/dist/tomcat/tomcat-8/v8.0.x/bin/apache-tomcat-8.0.x.tar.gz',
}
tomcat::instance { 'default':
  catalina_home => '/opt/tomcat',
}

Note: look up the correct version you want to install on the version list.

Usage

I want to run multiple instances of multiple versions of Tomcat

class { 'java': }

tomcat::install { '/opt/tomcat9':
  source_url => 'https://www.apache.org/dist/tomcat/tomcat-9/v9.0.x/bin/apache-tomcat-9.0.x.tar.gz'
}
tomcat::instance { 'tomcat9-first':
  catalina_home => '/opt/tomcat9',
  catalina_base => '/opt/tomcat9/first',
}
tomcat::instance { 'tomcat9-second':
  catalina_home => '/opt/tomcat9',
  catalina_base => '/opt/tomcat9/second',
}
# Change the default port of the second instance server and HTTP connector
tomcat::config::server { 'tomcat9-second':
  catalina_base => '/opt/tomcat9/second',
  port          => '8006',
}
tomcat::config::server::connector { 'tomcat9-second-http':
  catalina_base         => '/opt/tomcat9/second',
  port                  => '8081',
  protocol              => 'HTTP/1.1',
  additional_attributes => {
    'redirectPort' => '8443'
  },
}

Note: look up the correct version you want to install on the version list.

I want to upgrade the version of Tomcat to use

See information about running multiple versions above. Instead of upgrading in-place, install a second version to a new directory and then point the catalina_home of your instance to it. This gives you the ability to validate and rollback if needed. After validation, you may remove the older instance if you'd like. The links can be updated in order to match programmer preferences:

class { 'java': }

tomcat::install { '/opt/tomcat/9.0.24':
  source_url => 'https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.24/bin/apache-tomcat-9.0.24.tar.gz'
}
tomcat::install { '/opt/tomcat/9.0.44':
  source_url => 'https://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.46/bin/apache-tomcat-9.0.46.tar.gz'
}
tomcat::instance { 'my_tomcat_app':
# catalina_home => '/opt/tomcat/9.0.24',
  catalina_home => '/opt/tomcat/9.0.46',
  catalina_base => '/opt/my_tomcat_app',
}

I want to configure SSL and specify which protocols and ciphers to use

  file { $keystore_path:
    ensure => present,
    source => $keystore_source,
    owner => $keystore_user,
    mode => '0400',
    checksum => 'md5',
    checksum_value => $keystore_checksum,
  } ->

  tomcat::config::server::connector { "${tomcat_instance}-https":
    catalina_base         => $catalina_base,
    port                  => $https_port,
    protocol              => $http_version,
    purge_connectors      => true,
    additional_attributes => {
      'SSLEnabled'          => bool2str($https_enabled),
      'maxThreads'          => $https_connector_max_threads,
      'scheme'              => $https_connector_scheme,
      'secure'              => bool2str($https_connector_secure),
      'clientAuth'          => bool2str($https_connector_client_auth),
      'sslProtocol'         => $https_connector_ssl_protocol,
      'sslEnabledProtocols' => join($https_connector_ssl_protocols_enabled, ","),
      'ciphers'             => join($ciphers_enabled, ","),

      'keystorePass'        => $keystore_pass.unwrap,
      'keystoreFile'        => $keystore_path,
    },
  }

I want to deploy WAR files

Add the following to any existing installation with your own war source:

tomcat::war { 'sample.war':
  catalina_base => '/opt/tomcat9/first',
  war_source    => '/opt/tomcat9/webapps/docs/appdev/sample/sample.war',
}

The name of the WAR file must end with .war.

The war_source can be a local path or a puppet:///, http://, or ftp:// URL.

I want to remove some configuration

Different configuration defined types will allow an ensure parameter to be passed, though the name may vary based on the defined type.

To remove a connector, for instance, the following configuration ensure that it is absent:

tomcat::config::server::connector { 'tomcat9-jsvc':
  connector_ensure => 'absent',
  catalina_base    => '/opt/tomcat9/first',
  port             => '8080',
  protocol         => 'HTTP/1.1',
}

I want to manage a Connector or Realm that already exists

Describe the Realm or HTTP Connector element using tomcat::config::server::realm or tomcat::config::server::connector, and set purge_realms or purge_connectors to true.

tomcat::config::server::realm { 'org.apache.catalina.realm.LockOutRealm':
  realm_ensure => 'present',
  purge_realms => true,
}

Puppet removes any existing Connectors or Realms and leaves only the ones you've specified.

Reference

See REFERENCE.md

Limitations

For an extensive list of supported operating systems, see metadata.json

The tomcat::config::server* defined types require Augeas version 1.0.0 or newer.

Multiple Instances

Some Tomcat packages do not let you install more than one instance. You can avoid this limitation by installing Tomcat from source.

Development

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can't access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.

We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

For more information, see our module contribution guide.
