Recent Changes - Probe Integration (v2.0.0)

🎉 Major Update: YAML Workflows

The platform now uses YAML-based workflows powered by the probe task execution framework, replacing the previous JSON system.

Key Benefits:

• More readable workflow definitions
• 6 task types (was 3): HTTP, Database, SSH, Command, PowerShell, DownloadExec
• Better error handling and timeout support
• Extensible architecture for custom tasks
• Comprehensive documentation and examples

Migration Required

If you have existing JSON workflows, see automation-agent/MIGRATION-GUIDE.md for conversion instructions.

Quick Start

1. Probe Framework (Task Execution)

cd probe
go mod download
go test ./...

See probe/QUICKSTART.md for a 5-minute introduction.

2. Control Plane (Orchestration)

cd automation-control-plane

# Start with Docker Compose
docker-compose up -d

# Or deploy to Kubernetes
kubectl apply -f deploy/helm/

3. Automation Agent

cd automation-agent

# Build
go build -o automation-agent ./cmd/agent

# Configure (environment variables)
export CONTROL_PLANE_URL="http://localhost:8080"
export CENTRIFUGO_URL="ws://localhost:8000/connection/websocket"
export TENANT_ID="your-tenant-id"
export PROJECT_ID="your-project-id"
export JWT_TOKEN="your-jwt-token"

# Run
./automation-agent

# Or install as service
# Windows:
.\deploy\windows\install.ps1

# Linux:
sudo ./deploy/linux/install.sh

Building

# Probe module
cd probe
go build

# Agent
cd automation-agent
go build -o automation-agent ./cmd/agent

# Control Plane
cd automation-control-plane
go build -o control-plane ./cmd/server

Testing

# Probe
cd probe
go test ./... -v

# Agent
cd automation-agent
go test ./... -v

# Control Plane
cd automation-control-plane
go test ./... -v

Deployment

Development Environment

# Start control plane stack
cd automation-control-plane
docker-compose up -d

# Start agent
cd automation-agent
export CONTROL_PLANE_URL="http://localhost:8080"
export CENTRIFUGO_URL="ws://localhost:8000/connection/websocket"
export TENANT_ID="test"
export PROJECT_ID="test"
export JWT_TOKEN="your-token"
./automation-agent

Production Deployment

See deployment guides:

• Windows Agent
• Linux Agent
• Control Plane - Kubernetes
• Control Plane - Docker

Contributing

When adding new task types to probe:

1. Create task implementation in probe/task_yourtype.go
2. Implement the Task interface (Configure, Execute)
3. Add tests in probe/task_yourtype_test.go
4. Register in probe/probe.go New() function
5. Update documentation
6. Add example workflow

Troubleshooting

Agent won't connect

• Check CONTROL_PLANE_URL and CENTRIFUGO_URL
• Verify JWT token is valid
• Check firewall rules

Workflow fails to parse

• Validate YAML syntax
• Check task type names
• Verify all required config fields

SSH task fails

• Check SSH key permissions (0600 on Linux)
• Verify SSH server is accessible
• Test connection manually

PowerShell task fails on Linux

• PowerShell tasks only work on Windows
• Use command or ssh tasks instead

Version History

• v2.0.0 (2026-01-10) - Probe integration, YAML workflows
• v1.x - Initial release with JSON workflows

See CHANGELOG.md for detailed changes.
