Example Workflows

Auto-restart crashing pods

KubeRT Trigger (pod.crash_loop) → IF (restart_count > 5) → KubeRT (Pod > Restart)

Slack alert on anomaly detection

KubeRT Trigger (anomaly.detected) → Slack (Send Message)

Nightly rightsizing report

Schedule (daily) → KubeRT (Rightsizing > Get Recommendations) → Email (Send)

Auto-scale on high CPU

KubeRT Trigger (infra.node_pressure) → KubeRT (Cluster > Get Overview) → IF (cpu > 90%) → KubeRT (Workload > Deploy)

Install chart on new cluster

KubeRT Trigger (cluster.provisioned) → KubeRT (Catalog > Install) [monitoring stack]

Requirements

• KubeRT instance running with the API gateway accessible
• n8n v1.0.0 or later
• A KubeRT user account with appropriate permissions
