Automate message queue deployment on JBoss EAP
For decades now, software projects have relied on messaging APIs to exchange data. In the Java/Java EE ecosystem, this method of asynchronous communication has been standardized by the JMS specification. In many cases, individuals and organizations leverage Red Hat JBoss Enterprise Application Platform (JBoss EAP) to act as message-oriented middleware (MOM), which facilitates the management of message queues and topics.
Messaging ensures that no messages are lost as they are transmitted from the client and delivered to interested parties. On top of that, JBoss EAP provides authentication and other security-focused capabilities on top of the management functions.
In this article, we'll show how to fully automate the setup of JBoss EAP and a JMS queue using Ansible so that we can easily make this service available.
Prerequisites and installation
Install Ansible
First, we’ll set up our Ansible control machine, which is where the automation will be executed. On this system, we need to install Ansible as the first step:
$ sudo dnf install -y ansible-core
Note that the package name has changed recently from ansible to ansible-core.
Configure Ansible to use Red Hat Automation Hub
An extension to Ansible, an Ansible collection, dedicated to Red Hat JBoss EAP is available from Automation Hub. Red Hat customers need to add credentials and the location for Red Hat Automation Hub to their Ansible configuration file (ansible.cfg) to be able to install the content using the ansible-galaxy command-line tool.
Be sure to replace the with the API token you retrieved from Automation Hub. For more information about using Red Hat Automation Hub, please refer to the associated documentation.
#ansible.cfg:
[defaults]
host_key_checking = False
retry_files_enabled = False
nocows = 1
[inventory]
# fail more helpfully when the inventory file does not parse (Ansible 2.4+)
unparsed_is_failed=true
[galaxy]
server_list = automation_hub, galaxy
[galaxy_server.galaxy]
url=https://galaxy.ansible.com/
[galaxy_server.automation_hub]
url=https://cloud.redhat.com/api/automation-hub/
auth_url=https://sso.redhat.com/auth/realms/redhat-external/protocol/openid-connect/token
token=<paste-your-token-here>
Install the Ansible collection for JBoss EAP
With this configuration, we can now install the Ansible collection for JBoss EAP (redhat.eap) available on Red Hat Ansible Automation Hub:
$ ansible-galaxy collection install redhat.eap
Starting galaxy collection install process
Process install dependency map
Starting collection install process

redhat.runtimes_common:1.1.0 was installed successfully
Installing 'ansible.posix:1.5.4' to '/root/.ansible/collections/ansible_collections/ansible/posix'
ansible.posix:1.5.4 was installed successfully
As we will describe a little later on, this extension for Ansible will manage the entire installation and configuration of the Java application server on the target systems.
Inventory file
Before we can start using our collection, we need to provide the inventory of targets to Ansible. There are several ways to provide this information to the automation tool, but for the purposes of this article, we elected to use a simple ini-formatted inventory file.
To easily reproduce this article's demonstration, you can use the same control node as the target. This also removes the need to deploy the required SSH key on all the systems involved. To do so, simply use the following inventory file by creating a file called inventory:
[all]
localhost ansible_connection=local
[messaging_servers]
localhost ansible_connection=local
Deploying JBoss EAP
JBoss EAP installation
Before we configure the JMS queues that will be configured by Ansible, we'll first deploy JBoss EAP. Once the server is successfully running on the target system, we'll adjust the automation to add the required configuration to set up the messaging layer. This is purely for didactic purposes.
Since we can leverage the content of the redhat.eap collection, the playbook to install EAP and set it up as systemd service on the target system is minimal. Create a file called eap_jms.yml with the following content:
---
- name: "Deploy a JBoss EAP"
hosts: messaging_servers
vars:
eap_apply_cp: true
eap_version: 7.4.0
eap_offline_install: false
eap_config_base: 'standalone-full.xml'
collections:
- redhat.eap
roles:
- eap_install
- eap_systemd
Note that the Ansible collection for JBoss EAP will also take care of downloading the required assets from the Red Hat Customer Portal (the archive containing the Java app server files). However, one does need to provide the credentials associated with a service account. A Red Hat customer can manage service accounts using the hybrid cloud console. Within this portal, on the service accounts tab, you can create a new service account if one does not already exist.
Note: The values obtained from the hybrid cloud console are sensitive and should be managed accordingly. For the purpose of this article, the value is passed to the ansible-playbook command line. Alternatively, ansible-vault could be used to enforce additional defense mechanisms:
$ ansible-playbook -i inventory -e rhn_username=<client_id> -e rhn_password=<client_secret> eap_jms.yml

Validating the installation
Before going any further with our automation, we will be thorough and add a validation step to double-check that the application server is not only running but also functional. This will ensure, down the road, that any JMS-related issue only affects this subsystem.
The Ansible collection for JBoss EAP comes with a handy role, called eap_validation, for this purpose, so it's fairly easy to add this step to our playbook:
---
- name: "Deploy a JBoss EAP"
hosts: messaging_servers
vars:
eap_apply_cp: true
eap_version: 7.4.0
eap_offline_install: false
eap_config_base: 'standalone-full.xml'
collections:
- redhat.eap
roles:
- eap_install
- eap_systemd
- eap_validation
Let's execute our playbook once again and observe the execution of this validation step:
$ ansible-playbook -i inventory -e rhn_username=<client_id> -e rhn_password=<client_secret> eap_jms.yml

Deploying JMS queues on JBoss EAP using Ansible
Changing EAP configuration
Because the JMS subsystem is not used in the default JBoss EAP server configuration (standalone.xml), we also need to use a different profile (standalone-alone.xml). This is why, in the playbook above, we are specifying the required configuration profile:
---
- name: "Deploy a JBoss EAP"
hosts: messaging_servers
vars:
eap_apply_cp: true
eap_version: 7.4.0
eap_offline_install: false
eap_config_base: 'standalone-full.xml'
collections:
- redhat.eap
roles:
- eap_install
- eap_systemd
- eap_validation
Leveraging the YAML config feature of EAP using Ansible
In the previous section, JBoss EAP was installed and configured as a systemd service on the target systems. Now, we will update this automation to change the configuration of the app server to ensure a JMS queue is deployed and made available.
In order to accomplish this goal, we just need to provide a YAML definition with the appropriate configuration for the JMS subsystem of JBoss EAP. This configuration file is used by the app server, on boot, to update its configuration.
To achieve this, we need to add another file to our project that we named jms_configuration.yml.j2. While the content of the file itself is YAML, the extension is .j2 because it's a jinja2 template, which allows us to take advantage of the advanced, dynamic capabilities provided by Ansible.
jms_configuration.yml.j2:
wildfly-configuration:
subsystem:
messaging-activemq:
server:
default:
jms-queue:
{{ queue.name }}:
entries:
- '{{ queue.entry }}'
Below, you'll see the playbook updated with all the required parameters to deploy the JMQ queue on JBoss EAP:
---
- name: "Deploy a Red Hat JBoss EAP server and set up a JMS Queue"
hosts: messaging_servers
vars:
eap_apply_cp: true
eap_version: 7.4.0
eap_offline_install: false
eap_config_base: 'standalone-full.xml'
eap_enable_yml_config: True
queue:
name: MyQueue
entry: 'java:/jms/queue/MyQueue'
eap_yml_configs:
- jms_configuration.yml.j2
collections:
- redhat.eap
roles:
- eap_install
- eap_systemd
- eap_validation
Let's execute this playbook again:
$ ansible-playbook -i inventory -e rhn_username=<client_id> -e rhn_password=<client_secret> eap_jms.yml

As illustrated in the output above, the YAML definition is now enabled and the configuration of the JBoss EAP running on the target host has been updated.
Validate the JMS queue deployment
As always, we are going to be thorough and verify that the playbook execution has, indeed, properly set up a JMS queue. To do so, we can simply use the JBoss CLI provided with JBoss EAP to confirm:
$ /opt/jboss_eap/jboss-eap-7.4/bin/jboss-cli.sh --connect --command="/subsystem=messaging-activemq/server=default/jms-queue=MyQueue:read-resource"
{
"outcome" => "success",
"result" => {
"durable" => true,
"entries" => ["queues/MyQueue"],
"legacy-entries" => undefined,
"selector" => undefined
}
}
The output, as shown above, confirms that the server configuration has indeed been updated and that a brand new JMS queue is now available. Since this verification is fairly easy to automate, we will also add it to our playbook.
The Ansible collection for JBoss EAP comes with a handy wrapper allowing for the execution of the JBoss CLI within a playbook. So, all that is needed is the inclusion of the task and the desired command, as shown below:
post_tasks:
- name: "Check that Queue {{ queue.name }} is available."
ansible.builtin.include_role:
name: eap_utils
tasks_from: jboss_cli.yml
vars:
jboss_home: "{{ eap_home }}"
jboss_cli_query: "/subsystem=messaging-activemq/server=default/jms-queue={{ queue.name }}:read-resource"
Conclusion
Thanks to the Ansible collection for JBoss EAP, we have a minimalistic playbook, spared of all the heavy lifting of managing the Java application server, fulfilling the role of MOM. All the configuration required by the automation concerns only the use case we tried to implement, not the inner working of the solution (JBoss EAP).
All the configuration required by the automation concerns only the use case we tried to implement, not the inner working of the solution (JBoss EAP). The resulting playbook is safely repeatable and can be used to install the software on any number of target systems. Using the collection for JBoss EAP also makes it easy to keep the deployment up to date.
