Using OpenShift Virtualization as an environment for hosting Virtual Machines that are provisioned, configured and maintained using Ansible and tooling from the Ansible Middleware project.
The middleware_ocpv collection in infrastructure automation leverages Ansible to seamlessly handle the complete lifecycle of Virtual Machines within an OpenShift Virtualization runtime environment. It extends its functionality beyond VM management to include the streamlined installation, configuration, and ongoing management of deployed instances using the JBoss Enterprise Application Server (EAP).
What sets the middleware_ocpv collection apart is its ability to bridge the gap between the intricacies of OpenShift Virtualization and the demands of JBoss EAP deployments. Ansible serves as the linchpin, providing a user-friendly and cohesive platform for administrators to navigate the complexities of managing VMs and ensuring the seamless operation of enterprise-level applications.
This integration highlights the adaptability of Ansible in managing Virtual Machines within the dynamic and scalable OpenShift Virtualization environment, treating them with the same ease as any other hosting environment. Furthermore, by showcasing the deployment and management of an entire fleet of instances running Red Hat Application Services, the power and simplicity of Ansible automation become evident. The middleware_ocpv collection thus serves as a robust solution for efficiently handling diverse workloads in a sophisticated and integrated manner.
For this collection, the following resources must be available:
- OpenShift Container Platform
- Capable of running OpenShift Virtualization (Requirements)
cluster-adminaccess
- Ansible Controller (Part of Ansible Automation Platform) deployed to the same OpenShift environment as OpenShift Virtualization.
- Control Node capable of provisioning the collection environment
- Ansible
Certain requirements must be met prior to realizing the full potential of this collection. This involves not only completing steps within a local machine (control host), but also obtaining assets from external systems.
Tooling is available within this repository to provision the collection. Clone the repository to your local machine:
git clone https://github.com/redhat-cop/middleware_ocpv.git
cd middleware_ocpvAn SSH keypair is needed to communicate with the provisioned virtual machine. Provide the location of an SSH (without password) public key (.pub) and private key within the ssh_public_key_path and ssh_private_key_path variables in the vars/provision.yml file.
A token for the public Automation Hub must be obtained so that it can be configured to access certified content locally as part of the setup and provisioning process as well as being stored in Ansible Controller.
Steps for obtaining the token can be found here
The token must be added to two (2) locations:
- Set the value of
tokenin the ansible.cfg file - Set the value of the
automationhub_tokenvariables in the vars/provision.yml file
A Service Account as the associated Client ID and Client Secret must be provided so that the middleware assets can be generated from the Red Hat Customer Portal.
Obtain a Client ID and Client Secret by generating a Service Account here.
Set the values of the jbossnetwork_client_id and jbossnetwork_client_secret variables in the vars/provision.yml file.
The provisioned Virtual Machine will be subscribed so that it can obtain the required packages. Populate the redhat_csp_username and redhat_csp_password variables in the vars/provision.yml file with these values.
The provisioning process will configure Ansible Controller to manage the collection. The location of Controller as well as credentials must be specified. Set the controller_hostname, controller_username and controller_password variables in the vars/provision.yml file.
Install the required Python dependencies by executing the following command from the root of the cloned repository:
pip install -r requirements.txtInstall the required Ansible dependencies by executing the following command from the root of the cloned repository:
ansible-galaxy collection install -r requirements.ymlProvisioning the collection performs the following actions:
- Configures Ansible Controller
- Custom Credential Types
- Credentials
- Organization
- Project
- Inventory
- Job Templates
- Deploy OCPv
- Deploy collection
Ensure that you are logged into the OpenShift environment with a user with cluster-admin permissions and execute the following command:
ansible-playbook playbooks/provision.ymlOnce the configuration of Ansible Controller has completed successfully, login to Ansible Controller and navigate to the Templates tab underneath Resources.
Deploy OpenShift Virtualization by selecting the rocketship next to the Deploy OCPv Job Template to install and configure OpenShift Virtualization.
Once OpenShift Virtualization has been installed, execute the collection playbook. The collection provisioning process will perform the following actions:
- Create a new OpenShift namespace called
ansible-middleware-ocpv. - Create a RHEL 9 based Virtual Machine
- Perform Dynamic discovery of VirtualMachine instance to populate an inventory group called
eapwithin theocpvinventory. - Configure the Virtual Machine with the following:
- JBoss Enterprise Application Platform 7.4.0 (and associated dependencies [OpenJDK])
- Systemd service for JBoss EAP
- Deploy a sample application and make it available at the
/infocontext
- Create an OpenShift Service and Route exposing the JBoss Server
Once the automation has completed successfully, navigate to the ansible-middleware-ocpv within the OpenShift web console.
Within Administrator perspective, expand the Networking navigation pane on the left-hand side and select Routes.
Select the eap-collection route which will open the exposed VM and present the JBoss EAP welcome page.
Navigate to the /info context to view the deployed application.
Enjoy seeing the power of Ansible Middleware setup, configure and automate the deployment of Red Hat middleware within the OpenShift Container Platform!
