mule

Installs Mule Community or Enterprise Edition runtimes on a server.

Supported Platforms

• Ubuntu 14.04 LTS
• Centos 7.2

Usage

Mule should be run under a separate user with restricted permissions.

group 'mule' do
end

user 'mule' do
    supports manage_home: true
    shell '/bin/bash'
    home '/home/mule'
    comment 'Mule user'
    group 'mule'
end

Mule requires a Java Development Kit to run, and it is highly recommended you use Oracle JDK 8 to run Mule ESB.

include_recipe 'java'

Take note of the required node attributes required to download and install Oracle JDK

It is very easy to get started with the Mule LWRP:

mule_instance "mule-esb" do
    version '3.8.0'
    user 'mule'
    group 'mule'
end

The full syntax for all of the attributes in the Mule provider is:

mule_instance "name" do
    amc_setup           String
    archive_name        String
    enterprise_edition  TrueClass, FalseClass
    env                 String
    group               String
    home                String
    init_heap_size      String
    license             String
    max_heap_size       String
    name                String # defaults to 'name' if not specified
    source              String
    user                String
    version             String
    wrapper_additional  Array
    wrapper_defaults    TrueClass, FalseClass
    action              Symbol # defaults to :create if not specified
end

Anypoint Platform Integration

To register a server with the anypoint platform, the Chef recipe must get a token from Anypoint:

Chef::Recipe.send(:include, Mule::Helper)
regToken = amc_setup('Username','Password','Organization Name','Environment Name')

And use it to register the newly created runtime with the Anypoint Runtime Manager:

mule_instance 'mule-esb' do
    enterprise_edition true
    home '/usr/local/mule-esb'
    env 'test'
    user 'mule'
    group 'mule'
    action :create
    license 'muleLicense.lic'
    amc_setup regToken
end

Actions

This resource has the following actions:

:create

Default. Creates a Mule Runtime and installs it as a service.

Attributes

amc_setup

Ruby Types: String

The token used to register with Anypoint resource manager. Should be provided through the amc_setup helper method. See Usage. amc_setup does not run if enterprise_edition is false.

archive_name

Ruby Types: String

The name of the archive containing the Mule runtime. Defaults to "mule-ee-distribution-standalone-" + version if enterprise_edition is true and "mule-standalone-" + version if enterprise_edition is false.

enterprise_edition

Ruby Types: TrueClass, FalseClass

Flag determining if this is an Enterprise runtime. Defaults to false.

env

Ruby Types: String

The MULE_ENV variable, as used by the Mule Runtime. Defaults to 'test'.

group

Ruby Types: String

The group that owns the mule runtime. Defaults to 'mule'.

home

Ruby Types: String

Path to the MULE_HOME directory. Defaults to '/usr/local/mule-esb'.

init_heap_size

Ruby Types: String

The wrapper.java.initmemory parameters in the Tanuki Java Service Wrapper. Defaults to '1024' (m). If set to '0', the Wrapper will expect you to set the -Xms argument in wrapper_additional. Otherwise, the JVM will use its own built in defaults.

license

Ruby Types: String

The name of the mule license file. Will not install a license if enterprise_edition is set to false. Defaults to empty string, which skips the license install.

max_heap_size

Ruby Types: String

The wrapper.java.maxmemory parameters in the Tanuki Java Service Wrapper. Defaults to '1024' (m). If set to '0', the Wrapper will expect you to set the -Xmx argument in wrapper_additional. Otherwise, the JVM will use its own built in defaults.

name

Ruby Types: String

The name of the Mule ESB service to be installed. Defaults to the name of the resource block if not set.

source

Ruby Types: String

The path to the folder containing the mule archive and license. Defaults to '/tmp/mule'.

user

Ruby Types: String

The user that owns the mule runtime. Defaults to 'mule'.

version

Ruby Types: String

The version of Mule ESB to be installed. This is a required attribute.

wrapper_additional

Ruby Types: Array

An array of strings containing the arguments sent to the JVM through the wrapper.java.additional.n settings in the Tanuki Java Service Wrapper. Recommended arguments to the JVM will have sane defaults for mule if not included:

• -Dorg.glassfish.grizzly.nio.transport.TCPNIOTransport.max-receive-buffer-size=1048576
• -Dorg.glassfish.grizzly.nio.transport.TCPNIOTransport.max-send-buffer-size=1048576
• -XX:PermSize=256m
• -XX:MaxPermSize=256m
• -XX:NewSize=512m
• -XX:MaxNewSize=512m
• -XX:MaxTenuringThreshold=8

Arguments for the JVM that are set by default and do not need to be included:

• -Dmule.home="%MULE_HOME%"
• -Dmule.base="%MULE_HOME%"
• -Djava.net.preferIPv4Stack=TRUE
• -Dmvel2.disable.jit=TRUE
• -XX:+HeapDumpOnOutOfMemoryError
• -XX:+AlwaysPreTouch
• -XX:+UseParNewGC

wrapper_defaults

Ruby Types: TrueClass, FalseClass

Set this attributes to false if you don't want defaults and will set everything yourself, but -Dmule.home="%MULE_HOME%" and -Dmule.base="%MULE_HOME%" will always be set by the cookbook. Defaults to true.
