Galleon Provisioning Guide

1. Provisioning WildFly with Galleon

As opposed to a using traditional WildFly zip installation that installs it all (all default server configurations and all JBoss modules), using Galleon tooling you can choose to install a complete or customized WildFly server.

More information on Galleon features and tooling can be found in the Galleon docs.

1.1. Download and Installation of the Galleon Command Line Tool

Releases of the Galleon command line tool are available on the Galleon releases page.

Download and unzip the release zip and add the bin dir to your system path. Use galleon.sh or galleon.bat to launch the tool.

1.2. WildFly Galleon feature-packs

WildFly provides a Galleon feature-pack maven artifact (a zipped file that contains everything needed to dynamically provision a server). This feature-pack, as well as the feature-packs on which its depends, are deployed in public maven repositories.

When Galleon is used to install WildFly, WildFly feature-packs are retrieved and their content is assembled to create an installation.

1.3. Installing WildFly using Galleon

The Galleon maven plugin or Galleon CLI are used to install WildFly. The latest CLI and documentation can be downloaded from the Galleon releases page.

To install the latest final version of WildFly into the directory my-wildfly-server call:

galleon.sh install wildfly:current --dir=my-wildfly-server

Once installed, the directory my-wildfly-server contains all that is expected to run a complete WildFly server. By default, all standalone and domain configurations are installed.

Append the release version to install an identified release, for example:

galleon.sh install wildfly:current#21.0.0.Final --dir=my-wildfly-server

1.4. Selecting the configurations to install

Galleon allows you to specify only a subset of the default configurations to be installed.

To only install the standalone.xml configuration call:

galleon.sh install wildfly:current --dir=my-wildfly-server --default-configs=standalone/standalone.xml

To install multiple configurations, a comma separated list of default configurations can be provided, for example:

galleon.sh install wildfly:current --dir=my-wildfly-server --default-configs=standalone/standalone.xml,domain/domain.xml

A default configuration is identified by <configuration model>/<configuration name>. WildFly defines standalone and domain models. The configuration name is the XML configuration file name (e.g.: standalone.xml, domain.xml, standalone-ha.xml).

1.5. WildFly Galleon layers

WildFly Galleon feature-packs expose some Galleon layers. A layer identifies one or more server capabilities that can be installed on its own or in combination with other layers. For example, if your application (e.g. a microservice) is only making use of JAX-RS, Eclipse MicroProfile Config and CDI server capabilities, you can choose to only install the jaxrs, microprofile-config and cdi layers. The standalone.xml configuration would then only contain the required subsystems and their dependencies.

The benefit to installing WildFly using Galleon layers, in addition to configuration trim down, is that Galleon only installs the needed content (JBoss Modules modules, scripts, etc.)

To install a server only configured with the JAX-RS and CDI capabilities call:

galleon.sh install wildfly:current --dir=my-wildfly-server --layers=cdi,jaxrs

Once installed, the directory my-wildfly-server contains all that is expected to deploy an application that depends on JAX-RS and CDI.

Some layers optionally depend on other layers; i.e. the features provided by layer can and by default do make use of those from another layer, but if those are not present things will still work fine. In such a case if you do not want the optional capabilities you can exclude the optional layer by prefixing its name with a '-'. For example to exclude the optional CDI dependency on Bean Validation:

galleon.sh install wildfly:current --dir=my-wildfly-server --layers=cdi,jaxrs,-bean-validation

Tools (jboss-cli, add-user, …) are not always installed when installing WildFly using layers. In some cases, depending on what layers you use, only server launcher scripts are installed into the bin directory. To include these tools include the core-tools layer.

1.5.1. WildFly Layers

A Galleon layer is a name that identifies a server capability (e.g.: jaxrs, ejb, microprofile-config, jpa) or an aggregation of such capabilities. A layer captures a server capability in the form of:

A piece of server XML configuration (e.g.: extension, configured subsystem, interfaces) that describes the capability.
A set of modules and other filesystem content that implements the capability.

When you are using a layer, it delivers these pieces of information in order for Galleon to assemble a server containing only the required configuration and modules.

In the tables below we provide basic information about all of the layers WildFly provides.

Besides the layer names and a brief description of each, the tables below detail the various dependency relationships between layers. If the capabilities provided by a layer A require capabilities provided by another layer B, then layer A will depend on layer B. If you ask for layer A, then Galleon will automatically provide B as well. In some cases A’s dependency on B can be optional; that is A typically comes with B, but can function without it. In this case if you ask for A by default Galleon will provide B as well, but you can tell Galleon to exclude B.

Some layers are logical alternatives to other layers. If two layers are alternatives to each other they both provide the same general capabilities, but with different implementation characteristics. For example a number of layers provide the capability to cache different types of objects. These layers typically come in pairs of alternatives, where one alternative provides local caching, while the other provides distributed caching. If a layer you want has an optional dependency on a layer that has an alternative, you can exclude that dependency and instead specify the alternative. If a layer has an alternative the Description column in the tables below will identify it.

If the elytron layer is present, security will be handled by the elytron subsystem. The undertow and ejb subsystems are configured with an other application-security-domain that references the Elytron ApplicationDomain security domain.

Foundational Galleon layers

A single Galleon layer can provide a relatively small set of capabilities, but most users will want to start with a broader set of capabilities without having to spell out all the details. To help with this WildFly provides a few foundational layers all of which provide typical core WildFly capabilities like the logging subsystem and a secure remote management interface.

You don’t have to base your WildFly installation on one of these foundational layers, but doing so may be more convenient.
