F5 iRule Management

Goal

Provide a declarative interface for designing and deploying common programmable logic to a virtual service.

Overview

Python code will ingest a simplified (abstracted) YAML definition outlining desired programmability rules, and then leverage Terraform to deploy iRule to TM-OS appliance.

Unit Testing

We want to construct and automatically test any non-factory (e.g. not provided by Jinja) capabilities to ensure quality is up to snuff. The approach here MUST be eminently testable.

Since F5 programmability rules have validation performed on import, the best way to perform testing would be to test deployment to an actual TM-OS appliance via a pipeline. We'll use Terraform to do that.

HOWTO

Automated method

• Clone this repository.

• Configure deployment rules under CI tool (examples will be provided)

CLI method

python3 build-irule.py -i rule.yml -o rule.tcl
