# RobustaDev

Comprehensive guide for Robusta - the SRE agent that transforms Kubernetes alerts into actionable insights using playbooks, AI investigation, and automated remediation.

## Quick Reference

| Component | Purpose |
|-----------|---------|
| **Playbooks** | Rules engine defining alert responses |
| **Triggers** | Events that activate playbook execution |
| **Actions** | Remediation steps and enrichments |
| **Sinks** | Notification destinations (Slack, Teams, PagerDuty, etc.) |

## Workflow Routing

| Workflow | Trigger | File |
|----------|---------|------|
| **Install** | "install robusta", "deploy robusta" | `Workflows/Install.md` |
| **ConfigurePlaybooks** | "create playbook", "configure playbook" | `Workflows/ConfigurePlaybooks.md` |
| **ConfigureSinks** | "setup slack", "configure notifications" | `Workflows/ConfigureSinks.md` |
| **Troubleshoot** | "robusta not working", "alerts not firing" | `Workflows/Troubleshoot.md` |

## Installation Quick Start

### Prerequisites
- Kubernetes cluster
- Helm 3.x installed
- kubectl configured

### All-in-One Installation (Robusta + Prometheus)

```bash
# Generate configuration
pipx run robusta-cli gen-config --enable-prometheus-stack

# Or using Docker
curl -fsSL -o robusta https://docs.robusta.dev/master/_static/robusta
chmod +x robusta
./robusta gen-config --enable-prometheus-stack

# Install via Helm
helm repo add robusta https://robusta-charts.storage.googleapis.com
helm repo update
helm install robusta robusta/robusta \
  -f ./generated_values.yaml \
  --set clusterName=<YOUR_CLUSTER_NAME>

# Verify installation
kubectl get pods -A | grep robusta
```

### Standalone Installation (Existing Prometheus)

```bash
pipx run robusta-cli gen-config
helm install robusta robusta/robusta -f ./generated_values.yaml
```

## Playbook Structure

```yaml
# Example playbook in generated_values.yaml
customPlaybooks:
  - triggers:
      - on_prometheus_alert:
          alert_name: KubePodCrashLooping
    actions:
      - logs_enricher: {}
      - pod_events_enricher: {}
    sinks:
      - slack
```

### Trigger Types

| Trigger | Description |
|---------|-------------|
| `on_prometheus_alert` | Fires on Prometheus/AlertManager alerts |
| `on_pod_create` | When pod is created |
| `on_pod_update` | When pod is updated |
| `on_deployment_update` | When deployment changes |
| `on_schedule` | Cron-based scheduled execution |
| `on_kubernetes_warning_event` | On K8s warning events |

### Common Actions

| Action | Purpose |
|--------|---------|
| `logs_enricher` | Add pod logs to alert |
| `pod_events_enricher` | Add K8s events |
| `node_cpu_enricher` | Add CPU metrics |
| `node_memory_enricher` | Add memory metrics |
| `deployment_status_enricher` | Add deployment info |
| `delete_pod` | Auto-remediate by deleting pod |
| `node_bash_enricher` | Run bash commands on node |

## Sink Configuration

### Slack

```yaml
sinksConfig:
  - slack_sink:
      name: main_slack
      slack_channel: alerts
      api_key: xoxb-your-token
```

### Microsoft Teams

```yaml
sinksConfig:
  - ms_teams_sink:
      name: teams_alerts
      webhook_url: https://outlook.office.com/webhook/...
```

### PagerDuty

```yaml
sinksConfig:
  - pagerduty_sink:
      name: pagerduty
      api_key: your-integration-key
```

### Webhook (Generic)

```yaml
sinksConfig:
  - webhook_sink:
      name: custom_webhook
      url: https://your-endpoint.com/alerts
```

## Examples

**Example 1: Install Robusta with Prometheus**
```
User: "Install Robusta on my AKS cluster"
-> Generate config with gen-config --enable-prometheus-stack
-> Add Helm repo and install with cluster name
-> Verify pods are running
```

**Example 2: Create crash loop enrichment playbook**
```
User: "Add pod logs to CrashLoopBackOff alerts"
-> Create playbook with on_prometheus_alert trigger
-> Add logs_enricher and pod_events_enricher actions
-> Configure Slack sink for notifications
```

**Example 3: Configure Slack notifications**
```
User: "Send Robusta alerts to #k8s-alerts Slack channel"
-> Add slack_sink to sinksConfig
-> Set channel name and API key
-> Optionally filter by severity or namespace
```

**Example 4: Debug missing alerts**
```
User: "Robusta isn't sending alerts to Slack"
-> Check robusta-runner pod logs
-> Verify sink configuration in generated_values.yaml
-> Test with manual trigger: robusta playbooks trigger
```

## Key Concepts

### Alert Flow
```
Prometheus Alert -> AlertManager -> Robusta -> Playbook -> Actions -> Sinks
```

### Playbook Components
1. **Triggers** - What events activate the playbook
2. **Actions** - What to do when triggered (enrich, remediate)
3. **Sinks** - Where to send the result

### Smart Grouping
Robusta groups related alerts using Slack threads to reduce notification spam.

### AI Investigation (HolmesGPT)
Optional AI-powered root cause analysis available with Robusta Pro or self-hosted HolmesGPT.
