Minikube Deploy (Zero-Shot) Skill

Minikube Deploy (Zero-Shot)

Deploy ANY project to Minikube in a single iteration with automatic service detection and Helm chart generation.

Zero-Shot Workflow

PREREQ → DETECT (services + Dapr) → GENERATE → BUILD → DEPLOY → VERIFY

Execute ALL steps without stopping. Only ask user if:

Critical info is missing
Dapr detection score is 2-4 (ambiguous - ask "Enable Dapr?")

Step 0: PREREQUISITES

Run prerequisite check first to catch issues early:

# Check all requirements
.claude/skills/minikube-deploy/assets/scripts/check-prerequisites.sh

Or manually verify:

Docker installed and running
Minikube installed
kubectl installed
Helm installed
At least one Dockerfile exists

Cross-Platform Docker Setup:

# Linux/macOS/Git Bash
eval $(minikube docker-env)

# Windows PowerShell
& minikube docker-env --shell powershell | Invoke-Expression

# Windows CMD
@FOR /f "tokens=*" %i IN ('minikube docker-env --shell cmd') DO @%i

Step 1: DETECT

1.1 Find Services

# Find all Dockerfiles
find . -name "Dockerfile" -o -name "Dockerfile.*" 2>/dev/null | grep -v node_modules | grep -v .git

# Check for docker-compose
ls docker-compose*.yml docker-compose*.yaml compose*.yml 2>/dev/null

# Find env files
find . -name ".env" -o -name ".env.example" 2>/dev/null | grep -v node_modules | head -5

1.2 Parse Each Dockerfile

For each Dockerfile, extract:

# Port
grep -i "^EXPOSE" <path> | awk '{print $2}' | head -1

# Service name = parent folder name
dirname <path> | xargs basename

1.3 Detect Health Probe Paths

Use the health probe detector or scan code:

# Auto-detect health endpoints
.claude/skills/minikube-deploy/assets/scripts/detect-health-probes.sh

Framework defaults if not detected:

| Framework | Default Health Path | |-----------|-------------------| | FastAPI | /health | | Next.js | /api/health | | Express | /health | | Spring | /actuator/health | | Django | /health/ | | Unknown | / |

1.4 Build Service Map

PROJECT_NAME = <root-folder-name>
SERVICES = [
  {name: "api", path: "apps/api", port: 8000, type: "backend", healthPath: "/health"},
  {name: "frontend", path: "apps/frontend", port: 3000, type: "frontend", healthPath: "/"},
  ...
]

Type detection:

Port 3000/3001/5173 + (next|react|vue|vite) → frontend
Port 8000/8080/5000 + (fastapi|flask|express) → backend/api
No EXPOSE or worker/job in name → worker

1.5 Detect Dapr Requirement

Run the Dapr detector to determine if Dapr should be enabled:

.claude/skills/minikube-deploy/assets/scripts/detect-dapr-need.sh

Auto-detection triggers (score-based):

| Indicator | Score | Meaning | |-----------|-------|---------| | Existing Dapr config | +10 | Dapr required | | Kafka/Redpanda in compose | +3 | Event streaming | | Redis in compose | +2 | Pub/sub or state | | DaprClient in code | +5 | Already using Dapr | | Pub/sub patterns | +2 | Event-driven code | | 3+ services | +2 | Microservices |

Decision logic:

Score >= 5 → Enable Dapr automatically
Score 2-4 → Ask user: "Enable Dapr for event-driven features?"
Score < 2 → Skip Dapr (simple deployment)

Set DAPR_ENABLED=true/false for subsequent steps.

Step 2: GENERATE

2.1 Create Helm Structure

PROJECT="<detected-name>"
mkdir -p helm/$PROJECT/templates

2.2 Chart.yaml

# helm/$PROJECT/Chart.yaml
apiVersion: v2
name: $PROJECT
description: Auto-generated chart for $PROJECT
type: application
version: 1.0.0
appVersion: "1.0.0"

2.3 values.yaml

Generate dynamically based on detected services:

# helm/$PROJECT/values.yaml
namespace: $PROJECT
imagePullPolicy: IfNotPresent

configMap:
  NODE_ENV: "production"

# Dapr configuration (if DAPR_ENABLED=true)
dapr:
  enabled: $DAPR_ENABLED  # true or false based on Step 1.5
  logLevel: "info"
  pubsub:
    type: "pubsub.redis"  # or pubsub.kafka
  statestore:
    type: "state.redis"

# Repeat for EACH detected service:
$SERVICE_NAME:
  enabled: true
  replicaCount: 1
  image:
    repository: $SERVICE_NAME
    tag: latest
  service:
    type: ClusterIP  # NodePort for external
    port: $DETECTED_PORT
  resources:
    requests: {cpu: 100m, memory: 128Mi}
    limits: {cpu: 200m, memory: 256Mi}
  probes:
    enabled: true
    path: /health  # or / for frontends

2.4 Templates

_helpers.tpl:

{{- define "$PROJECT.fullname" -}}
{{- .Release.Name | trunc 63 | trimSuffix "-" }}
{{- end }}

configmap.yaml:

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ include "$PROJECT.fullname" . }}-config
  namespace: {{ .Values.namespace }}
data:
  {{- range $key, $value := .Values.configMap }}
  {{ $key }}: {{ $value | quote }}
  {{- end }}

For EACH service, create templates/$SERVICE/deployment.yaml:

{{- if .Values.$SERVICE.enabled }}
apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ include "$PROJECT.fullname" . }}-$SERVICE
  namespace: {{ .Values.namespace }}
  labels:
    app.kubernetes.io/name: $SERVICE
    app.kubernetes.io/instance: {{ .Release.Name }}
spec:
  replicas: {{ .Values.$SERVICE.replicaCount }}
  selector:
    matchLabels:
      app: $SERVICE
  template:
    metadata:
      labels:
        app: $SERVICE
        app.kubernetes.io/name: $SERVICE
      {{- if .Values.dapr.enabled }}
      annotations:
        dapr.io/enabled: "true"
        dapr.io/app-id: "{{ include "$PROJECT.fullname" . }}-$SERVICE"
        dapr.io/app-port: "{{ .Values.$SERVICE.service.port }}"
        dapr.io/log-level: "{{ .Values.dapr.logLevel }}"
      {{- end }}
    spec:
      containers:
        - name: $SERVICE
          image: "{{ .Values.$SERVICE.image.repository }}:{{ .Values.$SERVICE.image.tag }}"
          imagePullPolicy: {{ .Values.imagePullPolicy }}
          ports:
            - containerPort: {{ .Values.$SERVICE.service.port }}
          envFrom:
            - configMapRef:
                name: {{ include "$PROJECT.fullname" . }}-config
          resources:
            {{- toYaml .Values.$SERVICE.resources | nindent 12 }}
{{- end }}

For EACH service, create templates/$SERVICE/service.yaml:

{{- if .Values.$SERVICE.enabled }}
apiVersion: v1
kind: Service
metadata:
  name: $SERVICE
  namespace: {{ .Values.namespace }}
spec:
  type: {{ .Values.$SERVICE.service.type }}
  ports:
    - port: {{ .Values.$SERVICE.service.port }}
      targetPort: {{ .Values.$SERVICE.service.port }}
  selector:
    app: $SERVICE
{{- end }}

Step 3: BUILD

3.1 Setup Minikube Docker

# Start minikube if needed
minikube status || minikube start --driver=docker --cpus=2 --memory=4096

# Use minikube's Docker daemon
eval $(minikube docker-env)

3.2 Build Each Image

For EACH detected service:

docker build -t $SERVICE_NAME:latest -f $DOCKERFILE_PATH $CONTEXT_PATH

Context rules:

apps/api/Dockerfile → context = apps/api
./Dockerfile → context = .
services/worker/Dockerfile → context = services/worker

3.3 Verify

docker images | grep -E "service1|service2|..."

Step 4: DEPLOY

4.1 Create Namespace

kubectl create namespace $PROJECT --dry-run=client -o yaml | kubectl apply -f -

4.2 Install Dapr (if DAPR_ENABLED=true)

Only if Dapr was detected/requested in Step 1.5:

# Add Dapr Helm repo
helm repo add dapr https://dapr.github.io/helm-charts/
helm repo update

# Install Dapr control plane
helm upgrade --install dapr dapr/dapr \
  --namespace dapr-system \
  --create-namespace \
  --wait

# Verify Dapr is running
kubectl get pods -n dapr-system
# Expected: dapr-operator, dapr-sentry, dapr-sidecar-injector, dapr-placement

Install Redis for Dapr (if using Redis backend):

helm repo add bitnami https://charts.bitnami.com/bitnami
helm upgrade --install redis bitnami/redis \
  --namespace $PROJECT \
  --set auth.enabled=false \
  --set architecture=standalone \
  --wait

4.3 Create Secrets (if .env exists)

kubectl create secret generic $PROJECT-secrets \
  --namespace=$PROJECT \
  --from-env-file=.env \
  --dry-run=client -o yaml | kubectl apply -f -

4.4 Deploy Dapr Components (if DAPR_ENABLED=true)

Create Dapr components for pub/sub and state store. See references/dapr-integration.md for templates.

4.5 Helm Deploy

helm upgrade --install $PROJECT ./helm/$PROJECT \
  --namespace $PROJECT \
  --wait --timeout 5m

Step 5: VERIFY

# Pods
kubectl get pods -n $PROJECT

# Services
kubectl get svc -n $PROJECT

# Quick log check
kubectl logs -l app.kubernetes.io/instance=$PROJECT -n $PROJECT --tail=10

Access Instructions

Provide port-forward commands:

# For each service that needs external access:
kubectl port-forward svc/$SERVICE $LOCAL_PORT:$SERVICE_PORT -n $PROJECT

Dapr Integration Summary

Dapr is automatically detected in Step 1.5 and enabled if:

Existing Dapr configuration found
Kafka/Redpanda/Redis detected in docker-compose
DaprClient or pub/sub patterns in code
User explicitly requests it

When Dapr is enabled:

Dapr control plane installed in dapr-system namespace
Redis installed for pub/sub and state store
Dapr annotations added to deployments
Dapr components created for pub/sub and state

For detailed Dapr setup: See references/dapr-integration.md

Common Patterns

| Project Type | Detection | Services | |-------------|-----------|----------| | Monorepo apps/* | Multiple Dockerfiles in apps/ | One per app | | Single app | One Dockerfile in root | Single service | | docker-compose | Parse compose file | Match compose services | | Microservices | services/ or packages/ | One per directory |

Port Defaults

| Type | Port | NodePort | |------|------|----------| | Frontend | 3000 | 30000 | | API | 8000 | 30010 | | Worker | N/A | N/A |

Troubleshooting

| Issue | Fix | |-------|-----| | ImagePullBackOff | eval $(minikube docker-env) before build | | CrashLoopBackOff | kubectl logs <pod> -n <ns> | | Connection refused | kubectl port-forward svc/<name> <port> | | IPv6/ETIMEDOUT | See common-issues.md | | Windows issues | See common-issues.md |

For detailed troubleshooting: See references/common-issues.md

Error Recovery

If deployment fails:

Check logs: kubectl logs <pod> -n <namespace> --previous
Check events: kubectl get events -n <namespace> --sort-by='.lastTimestamp'

Cleanup and retry:

helm uninstall <project> -n <namespace>
kubectl delete namespace <namespace>
# Fix issue, then re-run deployment
