The intersection of Application Delivery Controllers (ADCs) and infrastructure-as-code (IaC) represents a fundamental shift in how modern enterprises manage traffic, security, and application availability. The integration of F5 technology with Red Hat Ansible provides a robust framework for automating the application lifecycle, moving away from manual, error-prone CLI or GUI configurations toward a programmatic, version-controlled environment. By leveraging Ansible's agentless architecture, organizations can treat their networking hardware and virtual appliances as software, ensuring that the deployment of security policies, load-balancing rules, and system configurations is consistent across disparate cloud and on-premises environments. This synergy allows for the rapid transition to modern application platforms, where the speed of the network must match the speed of the CI/CD pipeline to avoid becoming a bottleneck in the software delivery process.
The Strategic Value of F5 and Ansible Integration
The collaboration between F5 and Red Hat Ansible is designed to address the complexities of modern digital experiences. When organizations automate their security and networking processes, they shift their operational focus from repetitive maintenance to high-level architectural optimization.
The primary drivers for this integration include:
- Optimize Deployments: By integrating automation directly into CI/CD pipelines, applications can be deployed in minutes rather than hours. This capability extends to the creation and teardown of test environments, which increases overall reliability and significantly lowers the time to market for new features.
- Risk and Downtime Management: Automation reduces the probability of human error during the validation of infrastructure and application changes. Furthermore, the use of proactive, event-driven security automation allows the system to mitigate risks in real-time, rather than relying on manual intervention after a breach or failure has occurred.
- Acceleration of Time to Value: The availability of certified, pre-built F5 modules in Ansible Galaxy and certified Ansible Collections ensures that engineers do not have to write complex API calls from scratch. This standardization prevents misconfigurations across various clouds, networks, and devices, maintaining a uniform policy posture.
- Event-Driven Security Response: Through the use of Red Hat Event-Driven Ansible combined with F5's monitoring capabilities, the infrastructure can respond automatically to security events. This means a security threat detected by F5 can trigger an immediate Ansible playbook to block the threat, reducing the window of vulnerability.
Technical Ecosystem and Collection Architecture
F5 maintains a sophisticated ecosystem of Ansible Collections to cater to different operational needs, ranging from imperative task execution to declarative state management.
The current landscape consists of four primary collections:
| Collection Name | Primary Use Case | Connection Plugin | Repository |
|---|---|---|---|
| f5_modules | BIG-IP Imperative APIs and Tasks | LOCAL | Imperative collection |
| f5_bigip | BIG-IP Declarative APIs and Tasks | HTTPAPI | Declarative collection |
| f5os | F5OS based devices APIs and Tasks | HTTPAPI | F5OS collection |
| next | BIG-IP Next and Central Manager APIs and Tasks | HTTPAPI | BIG-IP Next collection |
The distinction between these collections is critical for the automation engineer. The f5_modules collection is imperative, meaning it focuses on "how" to achieve a state by executing a series of tasks. In contrast, the f5_bigip and f5os collections lean toward declarative patterns, where the user defines the "desired state" and the collection ensures the device reaches that state.
Deep Dive into f5_modules and Imperative Automation
The f5networks.f5_modules collection is specifically engineered for managing F5 BIG-IP and BIG-IQ devices. It allows network engineers to integrate F5 solutions into a broader infrastructure-as-code workflow, ensuring that configuration, deployment, and management tasks are streamlined.
Installation and Environment Requirements
To successfully implement this collection, the environment must meet specific technical prerequisites:
- Ansible Version: >= 2.16
- Python Version: >= 3.9
- Required Python Library: packaging
The installation is performed via the Ansible Galaxy command-line tool. The standard installation command is:
bash
ansible-galaxy collection install f5networks.f5_modules
For advanced users who need to specify a custom installation location, the -p option is utilized:
bash
ansible-galaxy collection install f5networks.f5_modules -p ./collections
When a custom folder is specified, the ansible.cfg file must be updated to include this path, ensuring that the Ansible engine can locate the installed modules during playbook execution.
Execution Environment (EE) Configuration
For enterprise-grade deployments using Ansible Automation Platform, the collection should be included in the Execution Environment (EE) container. This is handled via a requirements file:
yaml
collections:
- name: ansible.netcommon
version: ">=2.0.0"
- name: f5networks.f5_modules
The use of EEs ensures that the Python dependencies and collection versions are locked, providing a consistent runtime environment across different automation controllers.
F5OS and the Next-Generation Hardware Platform
F5OS serves as the foundational operating system for the F5 VELOS and F5 rSeries platforms. This architecture represents a departure from traditional monolithic OS designs, utilizing a Kubernetes-based platform layer that integrates tightly with the Traffic Management Operating System (TMOS).
F5 VELOS and rSeries Characteristics
- F5 VELOS: This is a chassis-based system designed for unprecedented performance and scalability within a single Application Delivery Controller (ADC).
- F5 rSeries: An API-first platform designed to bridge the gap between traditional hardware and modern cloud-native infrastructures.
The f5os Ansible collection is dedicated to automating the configuration and interaction with the services provided by these platforms. This allows for the creation, editing, updating, and deletion of configuration objects on F5OS-based systems.
Version Compatibility Matrix
The following table outlines the supported versions of the F5 Ansible Declarative Collection relative to the F5OS version:
| Platform | F5OS Version | F5 Ansible Declarative Collection |
|---|---|---|
| VELOS | 1.3.1 | >= 1.0.0 |
| rSeries | 1.2.0 | >= 1.0.0 |
Implementation Strategies and Operational Workflows
The practical application of F5 automation often involves a transition from standalone playbooks to centralized management via tools like Ansible Tower.
Agentless Architecture and API Integration
One of the most significant advantages of using Ansible with F5 is its agentless nature. There is no requirement to install software or agents on the F5 device itself. Instead, Ansible leverages the native REST API provided by the F5 technology. This allows engineers to "plunge in" and begin automating immediately upon gaining network access to the device's management IP.
Scaling with Ansible Tower and SCM
For organizations scaling their automation, moving to Ansible Tower (or the Ansible Automation Platform) provides several critical benefits:
- GUI-Based Management: Tower provides a graphical interface that makes Playbooks more accessible to administrators who may not be comfortable with the command line.
- Version Control Integration: By integrating with Source Code Management (SCM) tools like GitHub, organizations can implement version control for their network configurations. This means every change to an F5 device is tracked, audited, and can be reverted if necessary.
- Role-Based Access Control (RBAC): Through the use of projects and organizations within Tower, companies can segment different teams (e.g., security teams vs. network teams) using RBAC, ensuring that only authorized personnel can execute specific playbooks against production environments.
An example workflow involves creating a project in GitHub containing the playbooks required to set up and configure an instance of F5 BIG-IP Virtual Edition (VE). Ansible Tower pulls the latest code from the SCM and executes it against the target VE, ensuring a repeatable and compliant deployment.
Support and Contribution Framework
The f5networks.f5_modules collection is categorized as Red Hat Ansible Certified Content. This certification provides a structured support path:
- Primary Support: Users of the Ansible Automation Platform (AAP) can obtain official support by using the "Create issue" button on the collection's page.
- Community Support: For those who obtained the collection via Galaxy or GitHub and cannot open a case with Red Hat, issues can be reported through the GitHub issue tracker.
The project is published under the GPL V3 license. Furthermore, any individual or entity wishing to contribute code to the project must first complete and submit the F5 Contributor License Agreement to [email protected].
Conclusion
The integration of F5 and Ansible transforms the network from a static utility into a dynamic, programmable asset. By utilizing the specialized collections—f5_modules for imperative tasks, f5_bigip for declarative states, and f5os for next-generation hardware—organizations can achieve a level of operational maturity where infrastructure changes are treated with the same rigor as software releases. The shift toward an API-first approach, supported by the Kubernetes-based F5OS and the agentless nature of Ansible, eliminates the friction typically associated with network configuration. When combined with the orchestration capabilities of Ansible Tower and the versioning of GitHub, this ecosystem provides a complete framework for achieving compliance, enhanced security, and extreme efficiency in the delivery of digital experiences. The movement toward event-driven automation and the use of Execution Environments further ensures that F5 deployments are not only fast but are resilient and scalable across the entire enterprise landscape.
