Wildfly Cookbook

Cookbook to deploy the WildFly Java Application Server

Provides resources for installing/configuring WildFly and managing WildFly service instances for use in wrapper cookbooks. Installs WildFly from tarball and installs the appropriate configuration for your platform's init system.

Requirements

Platforms

• RHEL and derivatives
• Ubuntu

Chef

• Chef 12.11+

Usage

This cookbook has recently been rewritten to be resource-driven. It was a large undertaking and breaks old behavior, hence the major version bump. The API-driven configuration and deployment resources are much faster to converge.

The old recipes were kept around for similar, legacy behavior, but using the resources directly in your wrapper cookbook will yield more flexibility.

Example wrapper cookbook scenarios are available in the test cookbook, under test/fixtures/cookbooks/test

Attributes

• node['wildfly']['install_java'] - Install Java using Java Cookbook. Default true

Resource Providers

WildFly

• Installs and configures WildFly.

wildfly_wildfly 'wildfly' do
  mode 'standalone' # => WildFly Mode
  config 'standalone-full.xml' # => The WildFly Configuration File
  base_dir '/opt/wildfly' # => Directory to install WildFly to
  service_user 'wildfly'
  service_group 'wildfly'
  provision_user true # => Whether to create the WildFly service user/group
  create_mgmt_user true # => Provision a random, secure user for API interactions
  url 'http://.../wildfly.tar.gz' # URL to WildFly tarball to download
  checksum 'SHA256_CHECKSUM' # WildFly Tarball Checksum
  version '1.2.3' # Version of WildFly (Should correspond to URL)
end

Accessor Properties

• bind_management_http - the HTTP port for the Management Interface & API

Resource

• Flexible resource which allows provisioning of attributes and their parameters via the WildFly Management API. This should be used over other resources as it affords more flexibility.

wildfly_resource 'Syslog Handler' do
  path ['subsystem', 'logging', 'syslog-handler', 'SYSLOG']
  parameters 'app-name' => 'TEST',
             'enabled'  => true,
             'hostname' => 'localhost',
             'level'    => 'ALL',
             'port'     => 514,
             'server-address' => 'test.syslog.local',
             'syslog-format'  => 'RFC5424'
  action :create
end

Deploy API

• Resource to deploy applications via the API

# => URL-Based Deployment
wildfly_deploy_api 'Sample' do
  deploy_name 'sample-v1'
  runtime_name 'sample.war'
  parameters 'url' => 'https://github.com/apcera/sample-apps/raw/master/example-java-war/sample.war'
end

# => File-Based Deployment
myapp = remote_file 'helloworld' do
  source 'https://github.com/efsavage/hello-world-war/raw/master/dist/hello-world.war'
  path ::File.join(Chef::Config[:file_cache_path], 'hello-world.war')
  mode '0644'
  action :create
end

wildfly_deploy_api 'HelloWorld File Deployment' do
  deploy_name "HelloWorld-file-V1"
  runtime_name 'helloworld-file.war'
  parameters 'url' => 'file://' + myapp.path
end

Legacy Resources

• These will be deprecated in the future. The wildfly_resource resource can do everything these can, and via the much faster Management API. The deploy_api resource will replace the deploy resource as well.

Datasource

wildfly_datasource 'example' do
  jndiname 'java:jboss/datasource/example'
  drivername 'some-jdbc-driver'
  connectionurl 'jdbc:some://127.0.0.1/example'
  username 'db_username'
  password 'db_password'
  sensitive false
end

Deploy

Allows you to deploy JARs and WARs via chef

Example 1 (from a url)

wildfly_deploy 'jboss.jdbc-driver.sqljdbc4_jar' do
      url 'http://artifacts.company.com/artifacts/mssql-java-driver/sqljdbc4.jar'
end

Example 2 (from disk)

wildfly_deploy 'jboss.jdbc-driver.sqljdbc4_jar' do
      path '/opt/resources/sqljdb4.jar'
end

Example 3 with automated update (requires a common runtime_name and version specific name)

wildfly_deploy 'my-app-1.0.war' do
      url 'http://artifacts.company.com/artifacts/my-app.1.0.war'
      runtime_name 'my-app.war'
end

Example 4 undeploy (use :disable to keep the contents, and :enable to re-deploy previously kept contents)

wildfly_deploy 'jboss.jdbc-driver.sqljdbc4_jar' do
      action :remove
end

Attribute LWRP

Allows you to set an attribute in the server config

To change the max-post-size parameter

            <server name="default-server">
             <http-listener name="default" socket-binding="http" max-post-size="20971520"/>
           <host name="default-host" alias="localhost">

wildfly_attribute 'max-post-size' do
   path '/subsystem=undertow/server=default-server/http-listener=default'
   parameter 'max-post-size'
   value '20971520L'
   notifies :restart, 'service[wildfly]'
end

If the attribute restart is set to false, the wildfly will never restart

wildfly_attribute 'max-post-size' do
   path '/subsystem=undertow/server=default-server/http-listener=default'
   parameter 'max-post-size'
   value '20971520L'
   restart false
end

You can also add a new attribute

wildfly_attribute 'max-post-size' do
   path '/subsystem=mail/mail-session="postbox"'
   parameter 'jndi-name="java:/mail/postbox",debug=true'
   action :add
end

Property LWRP

Allows you to set or delete system properties in the server config. (Supported Actions: :set, :delete)

wildfly_property 'Database URL' do
   property 'JdbcUrl'
   value 'jdbc:mysql://1.2.3.4:3306/testdb'
   action :set
   notifies :restart, 'service[wildfly]', :delayed
end
