DevOps-Orchestra

DevOps Orchestra: A Multi-Agent AI-Powered DevOps Automation System

Project Description

DevOps Orchestra is a modular, event-driven DevOps automation platform powered by AI agents. It automates the entire software delivery lifecycle—from code validation and infrastructure provisioning to testing, deployment, monitoring, and recovery—by orchestrating a team of specialized agents. Each agent is responsible for a distinct DevOps function and communicates with others via a shared Kafka event bus, enabling fully automated, self-healing CI/CD pipelines.

Architecture & Agent Flow

Key Concepts:

• Event-Driven: All agents communicate and trigger actions via Kafka topics, ensuring loose coupling and scalability.
• Stateful: Each agent updates a shared state object, allowing context-aware decisions and handoffs.
• Config-Driven: The pipeline is governed by a devops_orchestra.yaml file in each repo, specifying build, test, deployment, infra, and notification preferences.

Agent Roles and Flow

1. GitOps Agent

   • Role: Entry point. Detects code pushes, clones repos, validates YAML, audits licenses, and updates the shared state.
   • Kafka Topics: Publishes to code_push.

2. Build Agent

   • Role: Builds the application using the specified tool (Docker, Maven, NPM, etc.). Generates Dockerfiles if missing.
   • Kafka Topics: Listens to code_push, publishes to build_ready.

3. Code Analysis Agent

   • Role: Performs static code analysis using LLMs, updates state with results, and publishes analysis events.
   • Kafka Topics: Listens to code_push, publishes to code_analysis.

4. Test Agent

   • Role: Auto-generates and runs tests using LLMs and the specified framework. Publishes results.
   • Kafka Topics: Listens to build_ready, publishes to test_results.

5. Infrastructure Agent (IaC Agent)

   • Role: Provisions cloud infrastructure using Terraform or CloudFormation, based on config. Generates missing IaC files using LLMs.
   • Kafka Topics: Listens to test_results, publishes to iac_ready.

6. Deployment Agent

   • Role: Deploys the application to the cloud using the specified strategy (e.g., blue-green, canary). Updates state with deployment status.
   • Kafka Topics: Listens to iac_ready, publishes to deployment_triggered.

7. Observability Agent

   • Role: Monitors deployed resources for health, latency, and error rates. Collects metrics (CPU, memory, disk, network, latency, error rates) and publishes alerts if thresholds are breached. Configurable thresholds via devops_orchestra.yaml.
   • Kafka Topics: Listens to deployment_triggered, publishes to observability_alert.

8. Rollback Agent

   • Role: Listens for critical failures or alerts. Triggers rollback to a previous version or runs terraform destroy as needed.
   • Kafka Topics: Listens to rollback_event.

9. ChatOps Agent

   • Role: Sends notifications (e.g., deployment success/failure, rollbacks) to users via Slack or other platforms, based on config.
   • Kafka Topics: Listens to various events, sends messages if enabled.

Event Bus (Kafka) Usage

• Kafka is the backbone of agent communication. Each agent listens to and publishes on specific topics, enabling asynchronous, decoupled workflows.
• Topics include: code_push, build_ready, code_analysis, test_results, iac_ready, deployment_triggered, observability_alert, rollback_event.
• Event schemas are defined in shared_modules/kafka_event_bus/event_schema.py for consistency and validation.

Pipeline Flow Example

1. Code push triggers the GitOps Agent.
2. Build Agent builds the app.
3. Code Analysis Agent checks code quality.
4. Test Agent generates and runs tests.
5. IaC Agent provisions cloud infrastructure.
6. Deployment Agent deploys the app.
7. Observability Agent monitors health.
8. Rollback Agent triggers if health checks fail.
9. ChatOps Agent notifies users of key events.

Note:

• All agents are implemented and working. The system provides a complete self-healing, fully automated pipeline.
• All configuration is driven by the devops_orchestra.yaml file in each repository.
