It provides a powerful web-based interface for defining, managing, and executing workflows that can span multiple servers, require human interaction, and perform complex automation tasks at scale. + +### Key Features + +- **Interactive Workflow Management**: Define and execute multi-step workflows with conditional logic, user prompts, and decision points +- **Distributed Execution**: Run commands and scripts across multiple worker nodes simultaneously +- **High Availability Architecture**: Deploy redundant worker nodes in LXC containers with Ceph storage for fault tolerance +- **Web-Based Control Center**: Intuitive interface for workflow selection, monitoring, and interactive input +- **Flexible Worker Pool**: Scale horizontally by adding worker nodes as needed +- **Real-Time Monitoring**: Track workflow progress, view logs, and receive notifications + +## Architecture + +PULSE consists of two core components: + +### PULSE Server +The central orchestration hub that: +- Hosts the web interface for workflow management +- Manages workflow definitions and execution state +- Coordinates task distribution to worker nodes +- Handles user interactions and input collection +- Provides real-time status updates and logging + +### PULSE Worker +Lightweight execution agents that: +- Connect to the PULSE server and await task assignments +- Execute commands, scripts, and code on target infrastructure +- Report execution status and results back to the server +- Support multiple concurrent workflow executions +- Automatically reconnect and resume on failure +``` +┌─────────────────────┐ +│ PULSE Server │ +│ (Web Interface) │ +└──────────┬──────────┘ + │ + ┌──────┴───────┬──────────────┬──────────────┐ + │ │ │ │ +┌───▼────┐ ┌───▼────┐ ┌───▼────┐ ┌───▼────┐ +│ Worker │ │ Worker │ │ Worker │ │ Worker │ +│ Node 1 │ │ Node 2 │ │ Node 3 │ │ Node N │ +└────────┘ └────────┘ └────────┘ └────────┘ + LXC Containers in Proxmox with Ceph +``` + +## Deployment + +### Prerequisites + +- **Proxmox VE Cluster**: Hypervisor environment for container deployment +- **Ceph Storage**: Distributed storage backend for high availability +- **LXC Support**: Container runtime for worker node deployment +- **Network Connectivity**: Communication between server and workers + +### Installation + +#### PULSE Server +```bash +# Clone the repository +git clone https://github.com/yourusername/pulse.git +cd pulse + +# Install dependencies +npm install # or pip install -r requirements.txt + +# Configure server settings +cp config.example.yml config.yml +nano config.yml + +# Start the PULSE server +npm start # or python server.py +``` + +#### PULSE Worker +```bash +# On each worker node (LXC container) +cd pulse-worker + +# Install dependencies +npm install # or pip install -r requirements.txt + +# Configure worker connection +cp worker-config.example.yml worker-config.yml +nano worker-config.yml + +# Start the worker daemon +npm start # or python worker.py +``` + +### High Availability Setup + +Deploy multiple worker nodes across Proxmox hosts: +```bash +# Create LXC template +pct create 1000 local:vztmpl/ubuntu-22.04-standard_amd64.tar.zst \ + --rootfs ceph-pool:8 \ + --memory 2048 \ + --cores 2 \ + --net0 name=eth0,bridge=vmbr0,ip=dhcp + +# Clone for additional workers +pct clone 1000 1001 --full --storage ceph-pool +pct clone 1000 1002 --full --storage ceph-pool +pct clone 1000 1003 --full --storage ceph-pool + +# Start all workers +for i in {1000..1003}; do pct start $i; done +``` + +## Usage + +### Creating a Workflow + +1. Access the PULSE web interface at `http://your-server:8080` +2. Navigate to **Workflows** → **Create New** +3. Define workflow steps using the visual editor or YAML syntax +4. Specify execution targets (specific nodes, groups, or all workers) +5. Add interactive prompts where user input is required +6. Save and activate the workflow + +### Example Workflow +```yaml +name: "System Update and Reboot" +description: "Update all servers in the cluster with user confirmation" +steps: + - name: "Check Current Versions" + type: "execute" + targets: ["all"] + command: "apt list --upgradable" + + - name: "User Approval" + type: "prompt" + message: "Review available updates.

Reboot all servers?" + options: ["Yes", "No"] + + - name: "Rolling Reboot" + type: "execute" + targets: ["all"] + command: "reboot" + strategy: "rolling" + condition: "prompt_response == 'Yes'" +``` + +### Running a Workflow + +1.
