Chapter 4. Adding Feature Packs to existing JBoss EAP Servers using the jboss-eap-installation-manager.

Procedure

1. Open your terminal emulator and navigate to the directory containing the downloaded jboss-eap-installation-manager.

2. Define the channels, that provide the feature packs, you want your JBoss EAP server subscribed to:

   ./jboss-eap-installation-manager.sh channel add \
     --channel-name feature-pack-channel \
     --repositories https://fp.repo.org/maven \
     --manifest com.example:feature-pack

3. Create and subscribe your JBoss EAP installation to a channel providing additional artifacts. For more information see Creating and subscribing your JBoss EAP installation to a channel providing additional artifacts.

1. Provide the necessary layers for the installation.

   $ ./jboss-eap-installation-manager.sh feature-pack add \
     --fpl com.example:feature-pack \
     --layers layer-one,layer-two \
     --dir jboss-eap8

2. Provide the necessary layers for the installation and choose the configuration file you want to modify.

   $ ./jboss-eap-installation-manager.sh feature-pack add \
     --fpl com.example:feature-pack \
     --layers layer-one,layer-two \
     --target-config standalone-ha.xml
     --dir jboss-eap8

   Note

   • You can modify the default feature pack configuration file by using the --target-config parameter. This parameter selects the configuration file in the standalone/configuration folder that will receive the changes.
   • If you have changed the chosen configuration file before, the updates won’t overwrite it. Instead, the changes will be saved in a new file named with a .glnew ending. You’ll need to handle and merge any conflicts yourself.
   • The feature pack can only modify standalone configuration files and not files in a managed domain.
   • The supported values for the --target-config parameter are the names of the configuration files provided by the base EAP8/XP5 servers. Additional feature packs should not provide additional configurations.

Procedure

1. Open the terminal emulator and navigate to the directory containing jboss-eap-installation-manager.

2. Create a provisioning.xml file and define the feature packs you want to install:

   <?xml version="1.0" ?>
   
   <installation xmlns="urn:jboss:galleon:provisioning:3.0">
       <feature-pack location="org.jboss.eap:wildfly-ee-galleon-pack:zip">
           <packages>
               <include name="docs.examples.configs"/>
           </packages>
       </feature-pack>
       <feature-pack location="<FEATURE_PACK_GROUP_ID>:<FEATURE_ARTIFACT_ID>:zip">
           <default-configs inherit="false"/>
           <packages inherit="false"/>
       </feature-pack>
       <config model="standalone" name="standalone.xml">
           <layers>
               <include name="<FEATURE_PACK_LAYER>"/>
           </layers>
       </config>
   </installation>

3. Create a channels.yaml file, and define the channels you want JBoss EAP subscribed to.

     schemaVersion: "2.0.0"
     name: "eap-8.0"
     repositories:
       - id: "mrrc"
         url: "file:/Users/spyrkob/workspaces/set/prospero/prod-prospero/jboss-eap-8.0.0.GA-maven-repository/maven-repository"
     manifest:
       maven:
         groupId: "org.jboss.eap.channels"
         artifactId: "eap-8.0"
     ---
     schemaVersion: "2.0.0"
     name: "feature-pack-channel"
     repositories:
       - id: "feature-pack-repository"
         url: "https://repository.example.com/feature-pack"
     manifest:
       maven:
         groupId: "com.example.channels"
         artifactId: "feature-pack"

4. Install feature packs using the --definition and --channel parameters:

   ./jboss-eap-installation-manager.sh install \
     --definition provisioning.xml \
       --channel channels.yaml \
       --dir jboss-eap8
   Installing galleon provisioning definition: provisioning.xml
   Using channels:
   # eap-8.0
     manifest: org.jboss.eap.channels:eap-8.0
     repositories:
       id: mrrc
       url: file:/tmp/jboss/jboss-eap-8.0.0.GA-maven-repository/maven-repository
   #feature-pack-channel
     manifest: com.example.channels:feature-pack
     repositories:
       id: feature-pack-repository
       url: https://repository.example.com/feature-pack

   Operation completed in 16.30 seconds

Procedure

1. Open the terminal emulator and navigate to the directory containing jboss-eap-installation-manager.

2. Install the required feature pack into JBoss EAP and specify the offline repositories by using --repositories parameter:

   $ ./jboss-eap-installation-manager.sh feature-pack add \
     --fpl com.example:feature-pack \
     --layers layer-one,layer-two \
     --repositories file:/path/to/eap8/offline_repo,file:/path/to/feature_pack/offline_repo
     --dir jboss-eap8

Procedure

1. Open the terminal emulator and navigate to the directory containing the downloaded jboss-eap-installation-manager.

2. Investigate the history of all feature packs added to your JBoss EAP server:

   $ ./jboss-eap-installation-manager.sh history --dir jboss-eap-8.0
   [79a553e7] 2023-08-23T13:39:10Z - feature_pack [org.jboss.eap.channels:eap-8.0::1.0.1.GA][com.example.channels:myfaces::1.0.0]
   [744013d2] 2023-08-23T13:38:16Z - config_change
   [928fe586] 2023-08-23T13:22:11Z - install [org.jboss.eap.channels:eap-8.0::1.0.1.GA]

3. Stop JBoss EAP server.

4. Revert your to a previous version.

   $ ./jboss-eap-installation-manager.sh revert perform --revision 744013d2 --dir jboss-eap-8.0

   Operation completed in 51.17 seconds.

Procedure

1. Open the terminal emulator and navigate to the directory containing jboss-eap-installation-manager.

2. Create a manifest.yaml file:

   schemaVersion: 1.0.0
   name: MyFaces manifest file
   streams:
     - groupId: org.apache.myfaces.core
       artifactId: myfaces-impl
       version: 4.0.0
     - groupId: org.apache.myfaces.core
       artifactId: myfaces-api
       version: 4.0.0

3. Deploy the manifest to a local repository:

   mvn deploy:deploy-file -Dfile=manifest.yaml \
     -DgroupId=com.example.channels -DartifactId=myfaces \
     -Dclassifier=manifest -Dpackaging=yaml -Dversion=1.0.0 \
     -Durl=file:/path/to/local/repository

4. Subscribe your JBoss EAP server to the new channel:

   $ ./jboss-eap-installation-manager.sh channel add \
     --channel-name myfaces-channel \
     --repositories https://repo1.maven.org/maven2,file:/path/to/local/repository \
       --manifest com.example.channels:myfaces \
     --dir jboss-eap8
