Incident Response·n8n workflow

Kubernetes Pod CrashLoop Alert

Detect K8s pod crashes; fetch last 50 logs; LLM diagnoses (app error, OOMKilled, liveness probe, etc.) and suggests recovery steps — escalate to #k8s-alerts.

Overview

**What it does**: Webhook (Kubernetes event: pod.status.reason=CrashLoopBackOff) → fetch pod logs from K8s API (last 50 lines) → LLM diagnoses: app segfault/exception, memory limit hit (OOMKilled), liveness probe timeout, readiness check fail → suggests recovery (increase CPU/mem, fix bug, adjust probe, check config) → Slack to #k8s-alerts with pod name, namespace, diagnosis. **Setup (5 steps)**: 1. Configure K8s event routing: set up Prometheus AlertManager or custom event webhook → point to n8n 2. Add K8s API credentials: service account token with pod log read permission 3. Configure Slack channel: #k8s-alerts 4. Set pod filters: namespaces/labels to monitor (e.g., exclude dev, test) 5. Test: force a pod crash; verify diagnosis appears in Slack within 30 seconds **Apps/nodes**: Webhook (K8s event), HTTP request (K8s API logs), OpenAI (diagnosis), Slack, IF branching. **Credentials required**: K8s cluster API access (service account token), OpenAI account, Slack workspace. **Difficulty**: Medium | **Setup time**: 10 minutes. **Business outcome**: Pod crashes diagnosed in seconds (not minutes of "why won't it start?") → MTTR ↓ 70%, oncall stress ↓ (diagnosis is instant), application stability ↑.

Frequently Asked Questions

How do I import this workflow into n8n?
Download the JSON file from your Library Pass, go to your n8n workspace, click the import button, select "Import from File", and upload the JSON. The entire workflow graph will load instantly, ready for configuration.
What credentials do I need to provide?
Each workflow lists required credentials in its description (e.g., Slack API key, GitHub token, PagerDuty account). You connect your own credentials—the workflow file contains only placeholder names, no actual API keys or secrets.
Are the credentials included in the JSON file?
No. For security, credential IDs are sanitized before distribution. You connect your own accounts when you first run the workflow. n8n will prompt you to authenticate each service.
Can I edit or customize the workflow after importing?
Yes, absolutely. Once imported, the workflow is yours to modify. You can change node logic, add/remove steps, adjust schedules, or integrate with different services. All changes are saved in your n8n workspace.
What n8n version is required?
These workflows use standard n8n-nodes-base node types (released 2022+). They work on n8n Cloud, self-hosted versions 0.180+, and Docker deployments. Community nodes (if required) are noted in the workflow description.
What if something breaks after I import it?
Check the workflow description for setup steps and credential names. Most issues are credential-related. If you get stuck, email support@autoflowworks.com with a screenshot of the error, and we'll help you troubleshoot.
Can I use this workflow for my customers or business?
Yes. The commercial-use license lets you keep, customize, and deploy the workflow for your business or clients. You can redistribute customized versions (except the original unmodified JSON without a valid Library Pass).
Will the workflow receive updates?
Yes. When we improve a workflow (fix bugs, add features, optimize node types), you'll get the updated JSON for free. Check your Library Pass dashboard for new versions.
Do I need n8n Pro or a paid plan?
Not necessarily. These workflows run on n8n Free if you have enough execution time and storage. For production use (frequent triggers, high data volumes, many webhooks), you may want n8n Cloud Pro or higher. Check n8n's pricing for details.
Can I ask for a custom workflow?
Yes! We offer custom workflow design for specific DevOps/SRE use cases. Visit /custom-solutions or email support@autoflowworks.com with your requirements for a quote.
