node['mule']['runtimes']

Attributes for Mule ESB runtimes are set as a list in the node['mule']['runtimes'] attribute:

{
    "mule": {
        "runtimes": [
            {
                "name": "mule-esb",
                "version": "3.8.0",
                "enterprise_edition": false,
                "license_name": "",
                "mule_source": "/tmp/mule",
                "mule_home": "/usr/local/mule-esb",
                "mule_env": ""
            }
        ]
    }
}

• name - The name of the Mule ESB service to be installed.
• version - The version of Mule ESB to be installed.
• enterprise_edition - Optional. Flag determining if this is an Enterprise runtime.
• license_name - Optional. The name of the mule license file. A missing attribute will skip license install.
• mule_source - The path containing the mule archive and license.
• mule_home - Path to the MULE_HOME directory.
• mule_env - The MULE_ENV variable, as used by the Mule Runtime.
• init_heap_size - Optional. The wrapper.java.initmemory parameters in the Tanuki Java Service Wrapper. Defaults to 1024 (m) when not set. If set to 0, the Wrapper will expect you to set the -Xms argument in wrapper_additional.
• max_heap_size - Optional. The wrapper.java.maxmemory parameters in the Tanuki Java Service Wrapper. Defaults to 1024 (m) when not set. If set to 0, the Wrapper will expect you to set the -Xmx argument in wrapper_additional.
• wrapper_additional - Optional. 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 should not be included:

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

Set the node['mule']['wrapper_defaults'] argument 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.

Usage

Mule requires a Java Development Kit to run, and it is highly recommended you use Oracle JDK 8 to run Mule ESB. To select Oracle JDK 8 and agree to the license, include the following in your role:

{
    "java": {
        "install_flavor": "oracle",
        "jdk_version": "8",
        "oracle": {
            "accept_oracle_download_terms": true
        }
    }
}

Otherwise, the default will be the OpenJDK as selected by the java cookbook.

If you wish to install java yourself, set the node['mule']['install_java'] attribute to false.

Include mule in your node's run_list:

{
  "run_list": [
    "recipe[mule::default]"
  ]
}

or in a recipe:

include_recipe 'mule::default'
