Case Template Generation Workflow

# 1. Get Azure context
call_az: {cli_command: "az account show -o json"}
  → subscription_id, subscription_name, tenant_id

# 2. Get cluster details
call_az: {cli_command: "az aks show -n <cluster> -g <rg> -o json"}
  → resource_uri, fqdn, k8s_version, region, node_rg

# 3. Run diagnosis
/k8s diagnose <cluster>
  → issues, severity, root_cause, affected_resources

# 4. Get timeline
call_kubectl: {args: "get events -A --sort-by=.lastTimestamp"}
  → problem_start_time, evidence

# 5. Generate case template markdown file
  → ~/Desktop/AKS-Support-Case-<cluster>-<timestamp>.md

## Problem Description

Pod `store-front` in namespace `pets` is in CrashLoopBackOff state with 16+ restarts. 
Container exits immediately with code 1 after startup.

## Affected Resources

| Type | Name | Namespace | Status |
|------|------|-----------|--------|
| Pod | store-front-6f467b6cdf-dcsfn | pets | CrashLoopBackOff |
| Deployment | store-front | pets | 1/2 available |
| Service | store-front | pets | Degraded |

## Initial Triage Outcomes

| Check | Result |
|-------|--------|
| Cluster Power State | ✅ Running |
| Node Health | ✅ 3/3 Ready |
| Control Plane | ✅ No errors |
| Pod Status | ❌ 1 CrashLoopBackOff |
| Resource Pressure | ✅ CPU 7%, Memory 17% |

## Suggested Root Cause

**Deployment modification injected crash command**

The deployment spec was modified to override the container entrypoint:
```yaml
command: ["/bin/sh", "-c"]
args: ["echo forcing crash; exit 1"]

This causes the container to exit immediately instead of running the application.

Evidence Summary

Timestamp	Source	Entry
21:14:40	Event	Scheduled: Assigned to aks-userpool-vmss00003l
21:14:51	Event	Started: Started container store-front
21:14:52	Log	"forcing crash"
21:14:52	Event	BackOff: Back-off restarting failed container

Remediation Attempted

• None yet

Recommended Fix

kubectl patch deployment store-front -n pets --type=json \
  -p='[{"op":"remove","path":"/spec/template/spec/containers/0/command"},
       {"op":"remove","path":"/spec/template/spec/containers/0/args"}]'

## Log Export Feature

The `/k8s logs --export` command creates a comprehensive ZIP archive containing all diagnostic data.

### Export Contents

| File | Description |
|------|-------------|
| `SUMMARY.md` | Issue summary with root cause and remediation |
| `events.txt` | All Kubernetes events |
| `pods.txt` | All pods status |
| `nodes.txt` | Node status |
| `nodes-describe.txt` | Detailed node descriptions |
| `node-metrics.txt` | Node CPU/Memory usage |

| `<problem-pod>-logs.txt` | Problem pod logs (for each failing pod) |
| `container-logs.json` | Container logs from Log Analytics |
| `cluster-info.json` | Full AKS cluster configuration |

### Export Workflow

```yaml
# 1. Create timestamped directory
mkdir ~/Desktop/aks-logs-YYYY-MM-DD-HHMMSS/

# 2. Export K8s resources via call_kubectl
call_kubectl: {args: "get events -A --sort-by=.lastTimestamp -o wide"} → events.txt
call_kubectl: {args: "get pods -A -o wide"} → pods.txt
call_kubectl: {args: "get nodes -o wide"} → nodes.txt
call_kubectl: {args: "describe nodes"} → nodes-describe.txt
call_kubectl: {args: "top nodes"} → node-metrics.txt
call_kubectl: {args: "top pods -A"} → pod-metrics.txt

# 3. Export problem pod details (for each failing pod)
call_kubectl: {args: "describe pod <pod> -n <ns>"} → <pod>-describe.txt
call_kubectl: {args: "logs <pod> -n <ns> --timestamps"} → <pod>-logs.txt

# 4. Export cluster config via call_az

Log Aggregation

The /k8s logs --aggregate command pulls logs from multiple sources and correlates them by timestamp.

Log Sources

Source	MCP Tool	What it captures
App Logs	call_kubectl → logs	Container stdout/stderr
Control Plane	az_monitoring → control_plane_logs	apiserver, controller-manager, scheduler
Node Logs	az_monitoring → KQL on ContainerLog	kubelet, containerd, OS events
Events	call_kubectl → get events	K8s warning/error events
App Insights	az_monitoring → app_insights	Application telemetry

Aggregated Output Format

📊 LOG AGGREGATION: <cluster> (last 1h)

TIMELINE:
─────────────────────────────────────────────────────
16:45:02 [CONTROL-PLANE] kube-scheduler: Failed to bind pod
16:45:03 [EVENT] FailedScheduling: 0/3 nodes available
16:45:15 [APP] store-front: Connection refused to mongodb

Issue Detection

Automatic checks when running /k8s status or /k8s diagnose:

1. Cluster power state (Running/Stopped)
2. Node conditions (NotReady, Pressure conditions)
3. Pod failures (CrashLoopBackOff, ImagePullBackOff, Pending, OOMKilled)
4. Warning events (last 1 hour)
5. Resource pressure (CPU > 80%, Memory > 85%)
