# Azure Container Instances Management

Analyze Azure Container Instances groups, resource utilization, and container health.

## Phase 1: Discovery

```bash
#!/bin/bash

echo "=== Container Groups Inventory ==="
az container list --output json \
  | jq -r '.[] | "\(.name)\t\(.resourceGroup)\t\(.provisioningState)\t\(.osType)\t\(.location)\t\(.ipAddress.ip // "none")"' \
  | column -t | head -20

echo ""
echo "=== Container Details ==="
for CG in $(az container list --query '[].name' -o tsv); do
  RG=$(az container show --name "$CG" --query 'resourceGroup' -o tsv 2>/dev/null)
  az container show --name "$CG" --resource-group "$RG" --output json \
    | jq '{name, state: .instanceView.state, restartCount: .containers[0].instanceView.restartCount, containers: [.containers[] | {name, image: .image, cpu: .resources.requests.cpu, memoryGB: .resources.requests.memoryInGB, state: .instanceView.currentState.state}]}' 2>/dev/null
done | head -30

echo ""
echo "=== Networking ==="
az container list --output json \
  | jq -r '.[] | "\(.name)\t\(.ipAddress.type // "none")\t\(.ipAddress.ip // "none")\t\(.ipAddress.ports[]? | "\(.port)/\(.protocol)" // "none")"' \
  | column -t | head -20

echo ""
echo "=== Volume Mounts ==="
az container list --output json \
  | jq '.[] | select(.volumes != null) | {name, volumes: [.volumes[] | {name, type: (if .azureFile != null then "azureFile" elif .gitRepo != null then "gitRepo" elif .emptyDir != null then "emptyDir" else "secret" end)}]}' \
  | head -20
```

## Phase 2: Analysis

```bash
#!/bin/bash

echo "=== Container Group Status ==="
for CG in $(az container list --query '[].name' -o tsv); do
  RG=$(az container show --name "$CG" --query 'resourceGroup' -o tsv 2>/dev/null)
  az container show --name "$CG" --resource-group "$RG" --output json \
    | jq '{
        name,
        state: .instanceView.state,
        events: [.instanceView.events[]? | {type, message: .message[0:80], timestamp: .firstTimestamp}] | last(3),
        containers: [.containers[] | {
          name,
          state: .instanceView.currentState.state,
          restarts: .instanceView.restartCount,
          exitCode: .instanceView.currentState.exitCode
        }]
      }' 2>/dev/null
done | head -40

echo ""
echo "=== Resource Utilization ==="
for CG in $(az container list --query '[].name' -o tsv); do
  RG=$(az container show --name "$CG" --query 'resourceGroup' -o tsv 2>/dev/null)
  echo "--- ${CG} ---"
  az monitor metrics list --resource "/subscriptions/$(az account show --query id -o tsv)/resourceGroups/${RG}/providers/Microsoft.ContainerInstance/containerGroups/${CG}" \
    --metric "CpuUsage,MemoryUsage" --interval PT1H \
    --aggregation Average Maximum \
    --query "value[].{metric:name.value, avg:timeseries[0].data[-1].average, max:timeseries[0].data[-1].maximum}" \
    -o table 2>/dev/null
done

echo ""
echo "=== Recent Container Logs ==="
for CG in $(az container list --query '[].name' -o tsv | head -5); do
  RG=$(az container show --name "$CG" --query 'resourceGroup' -o tsv 2>/dev/null)
  CONTAINER=$(az container show --name "$CG" --resource-group "$RG" --query 'containers[0].name' -o tsv 2>/dev/null)
  echo "--- ${CG}/${CONTAINER} ---"
  az container logs --name "$CG" --resource-group "$RG" --container-name "$CONTAINER" --tail 5 2>/dev/null
done

echo ""
echo "=== GPU Allocations ==="
az container list --output json \
  | jq '.[] | select(.containers[].resources.requests.gpu != null) | {name, gpu: .containers[].resources.requests.gpu}' 2>/dev/null
```

## Safety Rules

- **Read-only**: Only use `az container list`, `show`, `logs`, and `az monitor metrics`
- **Never start, stop, or delete** container groups without explicit confirmation
- **Log limits**: Always use `--tail` to prevent unbounded log output
- **Secrets**: Never output secret volume contents

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |
