Teardown llm-d Stack

Purpose

Cleanly remove a deployed llm-d stack from a Kubernetes namespace. Works with both Helm-based deployments (using helmfile or helm) and Kustomize-based deployments (using kubectl apply -k). No local repo is needed for Helm-only teardown, but Kustomize-based resources require access to the kustomization directory. Always confirms with the user before deleting anything.

---

Step 1: Locate the Stack and Set NAMESPACE

Use the same detection logic as the deploy and benchmark skills:

1. If the NAMESPACE environment variable is set, use it.
2. Otherwise check for an active oc project:

   oc project -q 2>/dev/null
   

3. If neither, ask the user for the namespace.

Verify the stack is present:

kubectl get pods -n $NAMESPACE
helm list -n $NAMESPACE

If no llm-d resources are found, tell the user and stop.

Step 2: Inspect What Is Deployed

Gather a full picture before proposing any changes:

# All Helm releases in the namespace
helm list -n $NAMESPACE

# HTTPRoutes and Gateways
kubectl get httproute,gateway -n $NAMESPACE 2>/dev/null

# All deployments (including those created by Kustomize)
kubectl get deployments -n $NAMESPACE

# All services
kubectl get services -n $NAMESPACE

# All pods
kubectl get pods -n $NAMESPACE

# Check for llm-d labels to identify Kustomize-deployed resources
kubectl get deployments,services,serviceaccounts,podmonitors -n $NAMESPACE -l llm-d.ai/guide 2>/dev/null

Identify deployment method:

• If Helm releases exist: Helm-based deployment
• If resources with llm-d.ai/guide labels exist but no Helm releases: Kustomize-based deployment
• If both exist: Hybrid deployment (common pattern)

---

Step 3: Present Teardown Plan and Confirm

Before touching anything, show the user exactly what will be removed and ask for confirmation:

Teardown plan for namespace: <NAMESPACE>

Deployment Method: <Helm-based | Kustomize-based | Hybrid>

Helm releases to uninstall:
  - <release-1>
  - <release-2>
  - <release-3>

Kustomize-deployed resources (if applicable):
  - Deployments: <list>
  - Services: <list>
  - ServiceAccounts: <list>
  - PodMonitors: <list>

Not removed unless you choose below:
  HTTPRoutes: <list or "none found">
  Gateways: <list or "none found">

Shall I proceed with the teardown?
