Jboss Admin Puppet Module

This module manages the resources within a running Jboss Wildfly (>= 7) or EAP (>= 6) container. For now it does not install the container, please refer to example42/puppet-jboss for a puppet module which handles initial Jboss installation.

This module can be used to configure any resource which can be managed from the Jboss CLI, including but not limited to:

• subsystems
• data-sources
• security-domains
• system-properties
• thread-pools
• etcetera

Status

This module is currently in beta. This module has been used in a large scale implementation, and in general is functional.

Please reference the issues for this project to understand the current defects and functionality under implementation.

Founding Concepts

This module is divided into three different sets of types: plumbing, porcelain and pattern. The intent is that the plumbing types will provide full coverage of container configuration with a generic interface. The porcelain types provide easy to use interfaces for specific container resources. Porcelain types have enhanced documentation, validation, and error handling that is specific to a single resource. Pattern types have enhanced documenation, validation, and error handling that is specific to a common pattern that combines multiple related plumbing and porcelain types.

Currently there are three plumbing types on which all porcelain types are built:

• jboss_resource: Ensures that a specific resource path is present or absent, and that all attributes have the specified values. Non-specified attributes are ignored.
• jboss_exec: Executes the specified command within the Jboss CLI. Executing the command can be made conditional based on the result of another command. This support is not dependent on a specific version if EAP/Wildfly.
• jboss_batch: Allows an ordered list of JBoss resources and JBoss CLI commands to be specified that will be ensured and executed in the specified ordered. The specifics of the specified JBoss resources and CLI commands work the same as they would in an individual jboss_resource or jboss_exec. That is if an address is specified for a resource with an ensure value and optional options then the jboss_batch operation will ensure that state of the resource. If any CLI commands are specified they they will be run. The jboss_batch will only execute if there are specified resources that are out of sync, or there are any CLI commands listed. But these cases will be ignored if an unless or onlyif statement fails its given test.

There are currently over 100 porcelain types. For example, here are a few porcelain types:

• access-log
• acl
• admin-objects
• archive-validation
• async-handler
• audit
• authentication_classic
• authentication_jaas
• authentication_jaspi
• authentication_ldap
• authentication_properties
• authentication_truststore
• authorization_classic
• authorization_properties

There is currently one pattern type:

• security_domain_with_authentication_classic

###Dependency Ordering###

This module attempts to decrease the amount of explicit dependency management needed by automatically requiring ancestor resources for any type. For example, /subsystem=datasources will always be configured before /subsystem=datasources/data-source=ExampleDS.

Similarly, any jboss_exec is only executed after the resource it is being executed against has been configured. This can be seen in the plumbing example below, where Jboss_exec[Enable Data Source] will always run after the data source has been created.

An explicit dependency must be declared when two resources that are not an ancestor and child are dependent.

How to Use

Following are some brief examples of using this modules types. Refer to each types documentation for more details.

The two provided examples both accomplish the same general task of ensuring a data source exists and is enabled. The main difference is that the porcelain type can validate parameter values when the puppet catalogue is compiled instead of causing an error while applying to the container. I would suggest using the porcelain types when possible.

###Porcelain Types###

jboss_admin::server {'main':
  base_path => '/opt/jboss'
}

jboss_admin::resource::data_source{'/subsystem=datasources/data-source=ExampleDS':
  ensure         => present,
  connection_url => 'jdbc:h2:mem:test;DB_CLOSE_DELAY=-1',
  driver_name    => h2,
  jndi_name      => 'java:jboss/datasources/ExampleDS2',
  jta            => true,
  user_name      => sa,
  password       => sa,
  server         => main
}

jboss_exec {'Enable Data Source':
  command => '/subsystem=datasources/data-source=ExampleDS:enable',
  unless  => '(result == true) of /subsystem=datasources/data-source=ExampleDS:read-attribute(name=enabled)',
  server  => main
}

###Plumbing Types###

jboss_admin::server {'main':
  base_path => '/opt/jboss'
}

jboss_resource {'/subsystem=datasources/data-source=ExampleDS':
  ensure => present,
  options => {
    'connection-url' => 'jdbc:h2:mem:test;DB_CLOSE_DELAY=-1',
    'driver-name'    => 'h2',
    'jndi-name'      => 'java:jboss/datasources/ExampleDS2',
    'jta'            => true,
    'user-name'      => 'sa',
    'password'       => 'sa'
  },
  server => main
}

jboss_exec {'Enable Data Source':
  command => '/subsystem=datasources/data-source=ExampleDS:enable',
  unless  => '(result == true) of /subsystem=datasources/data-source=ExampleDS:read-attribute(name=enabled)',
  server  => main
}

jboss_batch { "Datasource Batch":
  batch  => [
    { address => '/subsystem=datasources/data-source=ExampleDS',
      options => {
        'connection-url' => 'jdbc:h2:mem:test;DB_CLOSE_DELAY=-1',
        'driver-name'    => 'h2',
        'jndi-name'      => 'java:jboss/datasources/ExampleDS2',
        'jta'            => true,
        'user-name'      => 'sa',
        'password'       => 'sa'
      },  
      ensure  => present
    }   
  ],  
  server => main,
}

jboss_batch { "Datasource Batch":
  batch  => [
    { command => '/subsystem=datasources/data-source=ExampleDS:add',
      options => {
        'connection-url' => 'jdbc:h2:mem:test;DB_CLOSE_DELAY=-1',
        'driver-name'    => 'h2',
        'jndi-name'      => 'java:jboss/datasources/ExampleDS2',
        'jta'            => true,
        'user-name'      => 'sa',
        'password'       => 'sa'
      },  
      ensure  => present
    }   
  ],  
  server => main,
}

Generating Resources

Most of the resources inside the manifests/resource directory are generated based on the schema exported by jboss instead of hand made. The hope is that as new resources are added this will simplify the process of adding manifests for them. The code backing generation is in lib/tasks/schema_generate.rb, and the template is lib/tasks/manifest.erb.

Some types do not produce a great result when autogenerate, mostly when the jboss schema departs from its normal conventions. Any hand writeen resource manifests should go in manifests/internal/custom_resource. The generation task will overlay these files over the autogenerated version.

To regenerate resources, execute rake resource:generate within the project folder.

Developer Setup

This project is provided with a Vagrant setup for development of the module. The created VM has a running Jboss AS 7 instance at /opt/jboss for testing purposes.

To execute a test manifest, first execute bundle within the vagrant directory, then use the following pattern:

sudo puppet apply tests/enable_ExampleDS2.pp --modulepath=/modules

The server is setup for local authentication, and can be accessed with:

sudo -u jboss /opt/jboss/bin/jboss-cli.sh --connect
