Automating OpenShift VMs Compliance with Knative and Tekton the cloud-native way
Introduction
Background
In the rapidly evolving landscape of cloud computing, virtual machine (VM) provisioning in OpenShift environments has become increasingly streamlined. However, compliance tasks often remain a bottleneck, characterized by manual interventions, time-consuming configurations, and a high potential for human error. These challenges undermine the efficiency gains achieved through modern provisioning processes.
Objective
This project aims to revolutionize the VM compliance automation phase by automating these tasks using Knative and Tekton. Our goal is to enhance operational efficiency and reliability in managing OpenShift VIrtualization environments.
Problem Statement
Current compliance processes often involve cumbersome manual steps, leading to significant delays and high error rates. These include configuring network settings, installing software, and applying security patches.
Impact
These inefficiencies adversely affect resource utilization and operational costs, while increasing the likelihood of human error, thereby compromising system integrity and performance.
Proposed Solution
Overview
We propose a solution that leverages Knative to trigger Tekton pipelines, automating the compliance tasks in OpenShift environments.
How It Works
Upon VM creation, a Knative trigger will send the VM payload to a Tekton EventListener. This event triggers a Tekton pipeline, which is pre-configured to execute a series of compliance tasks automatically via Ansible.
Technologies Used
- OpenShift: A Kubernetes distribution that simplifies the management of Kubernetes clusters, providing a robust foundation for this solution.
- Knative: An event-driven framework that facilitates serverless workloads in Kubernetes, crucial for triggering automated workflows.
- Tekton: A powerful Kubernetes-native CI/CD framework, used here to create and manage the pipelines executing post-provisioning tasks.
- Ansible: Ansible is a suite of software tools that enables configuration as code. It is open-source and the suite includes software provisioning, configuration management, and application deployment functionality.
Implementation

A diagram will be provided to visually represent the workflow from VM creation to task completion.
Step-by-Step Process
The concept involves the creation of a Tekton pipeline whenever a VM is created/deleted. This pipeline accesses a configmap and subsequently executes automation tasks on the VM.
It is essential for the VM to have an annotation indicating the configmap's name.
Benefits
- Efficiency: Significantly reduces the time required for post-provisioning tasks.
- Reliability: Minimizes human error through automation.
- Scalability: Easily adapts to increasing infrastructure demands.
- Cost-Effectiveness: Reduces manpower requirements and operational costs.
Conclusion
This proposal outlines a transformative approach to managing compliance tasks in OpenShift VM environments. By leveraging Knative and Tekton, we can significantly enhance efficiency, reliability, scalability, and cost-effectiveness.
