DevOps Automation Agent

Secure a DevOps agent that deploys infrastructure, manages secrets, and executes privileged operations with short-lived credentials and delegation.

What This Example Shows

• Narrow Delegation: Sub-agents for different infrastructure tasks
• Short-Lived Credentials: Ephemeral credentials for privileged operations
• Resource-Specific Capability Grants: Fine-grained permissions
• Behavioral Scoring: Trust score adapts to behavior

Use Case

A DevOps automation agent that:

• Deploys applications to production
• Manages infrastructure secrets
• Executes database migrations
• Never allows unrestricted access to production
• Requires approval for destructive operations

Key Features

1. Short-Lived Credentials

# Request temporary credentials for deployment
cred = credential_manager.issue_credential(
    agent_id=deploy_agent.did,
    scope=["deploy:production"],
    ttl_minutes=15  # Expires in 15 minutes
)

2. Narrow Delegation

# Deploy agent can only deploy, not manage secrets
deploy_agent = supervisor.delegate(
    name="deploy-agent",
    capabilities=["deploy:staging", "deploy:production"]
)

# Secret manager can only read/write secrets
secret_agent = supervisor.delegate(
    name="secret-manager",
    capabilities=["read:secrets", "write:secrets"]
)

3. Require Approval for Destructive Operations

policies:
  - name: "approve-production-deployments"
    rules:
      - condition: "action == 'deploy' and environment == 'production'"
        action: "require_approval"
        approvers: ["sre-team@company.com"]

4. Behavioral Scoring

Agent trust score decreases on:

• Failed deployments
• Policy violations
• Unusual access patterns
• Credential misuse

Quick Start

# Install dependencies
pip install -r requirements.txt

# Run the DevOps agent
python main.py

Security Features

Feature	Implementation
Short-Lived Credentials	15-minute TTL, auto-rotation
Narrow Delegation	Each sub-agent has minimal capabilities
Approval Workflows	Destructive operations require human approval
Audit Trail	All operations logged
Risk Scoring	Trust score adapts to behavior
Secret Management	Integration with HashiCorp Vault

Example Output

🚀 DevOps Automation Agent

Supervisor: did:agentmesh:devops-supervisor
Trust Score: 920/1000

Sub-Agents:
  • deploy-agent (capabilities: deploy:staging, deploy:production)
  • secret-manager (capabilities: read:secrets, write:secrets)
  • database-agent (capabilities: migrate:database)

📋 Deployment Task: Deploy app-v2.0 to production

  1. ✓ Credentials issued (TTL: 15min)
  2. ✓ Approval requested from SRE team
  3. ⏳ Waiting for approval...
  4. ✓ Approval granted by john@company.com
  5. ✓ Deployment successful
  6. ✓ Trust score updated: 925/1000

Best Practices

1. Always use short-lived credentials for production access
2. Require approval for destructive operations
3. Monitor trust scores and set alerts
4. Rotate secrets automatically
5. Test in staging before production
