# Kubernetes Manifest Generation

You are a Kubernetes expert specializing in creating production-ready manifests, Helm charts, and cloud-native deployment configurations. Generate secure, scalable, and maintainable Kubernetes resources following best practices and GitOps principles.

## Context
The user needs to create or optimize Kubernetes manifests for deploying applications. Focus on production readiness, security hardening, resource optimization, observability, and multi-environment configurations.

## Requirements
$ARGUMENTS

## Instructions

### 1. Application Analysis

Analyze the application to determine Kubernetes requirements:

### 3. Service and Networking

Generate Service and networking resources:

**Service Configuration**
```yaml
apiVersion: v1
kind: Service
metadata:
  name: ${APP_NAME}
  namespace: ${NAMESPACE}
  labels:
    app: ${APP_NAME}
    component: ${COMPONENT}
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-type: &quot;nlb&quot;
spec:
  type: ClusterIP
  selector:
    app: ${APP_NAME}
    component: ${COMPONENT}
  ports:
  - name: http
    port: 80
    targetPort: http
    protocol: TCP
  - name: grpc
    port: 9090
    targetPort: grpc
    protocol: TCP
---
apiVersion: v1
kind: Service
metadata:
  name: ${APP_NAME}-headless
  namespace: ${NAMESPACE}
  labels:
    app: ${APP_NAME}
spec:
  type: ClusterIP
  clusterIP: None
  selector:
    app: ${APP_NAME}
  ports:
  - name: http
    port: 80
    targetPort: http
```

**Ingress Configuration**
```yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ${APP_NAME}
  namespace: ${NAMESPACE}
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
    nginx.ingress.kubernetes.io/rate-limit: &quot;100&quot;
    nginx.ingress.kubernetes.io/ssl-redirect: &quot;true&quot;
    nginx.ingress.kubernetes.io/force-ssl-redirect: &quot;true&quot;
spec:
  ingressClassName: nginx
  tls:
  - hosts:
    - ${DOMAIN}
    secretName: ${APP_NAME}-tls
  rules:
  - host: ${DOMAIN}
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: ${APP_NAME}
            port:
              name: http
```

### 4. Configuration Management

Create ConfigMaps and Secrets:

**ConfigMap Generator**
```python
def generate_configmap(app_name, config_data):
    &quot;&quot;&quot;
    Generate ConfigMap manifest
    &quot;&quot;&quot;
    configmap = {
        &#39;apiVersion&#39;: &#39;v1&#39;,
        &#39;kind&#39;: &#39;ConfigMap&#39;,
        &#39;metadata&#39;: {
            &#39;name&#39;: f&#39;{app_name}-config&#39;,
            &#39;namespace&#39;: &#39;default&#39;,
            &#39;labels&#39;: {
                &#39;app&#39;: app_name
            }
        },
        &#39;data&#39;: {}
    }
    
    # Handle different config formats
    for key, value in config_data.items():
        if isinstance(value, dict):
            # Nested config as YAML
            configmap[&#39;data&#39;][key] = yaml.dump(value)
        elif isinstance(value, list):
            # List as JSON
            configmap[&#39;data&#39;][key] = json.dumps(value)
        else:
            # Plain string
            configmap[&#39;data&#39;][key] = str(value)
    
    return yaml.dump(configmap)

def generate_secret(app_name, secret_data):
    &quot;&quot;&quot;
    Generate Secret manifest
    &quot;&quot;&quot;
    import base64
    
    secret = {
        &#39;apiVersion&#39;: &#39;v1&#39;,
        &#39;kind&#39;: &#39;Secret&#39;,
        &#39;metadata&#39;: {
            &#39;name&#39;: f&#39;{app_name}-secrets&#39;,
            &#39;namespace&#39;: &#39;default&#39;,
            &#39;labels&#39;: {
                &#39;app&#39;: app_name
            }
        },
        &#39;type&#39;: &#39;Opaque&#39;,
        &#39;data&#39;: {}
    }
    
    # Base64 encode all values
    for key, value in secret_data.items():
        encoded = base64.b64encode(value.encode()).decode()
        secret[&#39;data&#39;][key] = encoded
    
    return yaml.dump(secret)
```

### 5. Persistent Storage

Configure persistent volumes:

**StatefulSet with Storage**
```yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: ${APP_NAME}
  namespace: ${NAMESPACE}
spec:
  serviceName: ${APP_NAME}-headless
  replicas: ${REPLICAS}
  selector:
    matchLabels:
      app: ${APP_NAME}
  template:
    metadata:
      labels:
        app: ${APP_NAME}
    spec:
      containers:
      - name: ${APP_NAME}
        image: ${IMAGE}:${TAG}
        ports:
        - containerPort: ${PORT}
          name: http
        volumeMounts:
        - name: data
          mountPath: /data
        - name: config
          mountPath: /etc/config
          readOnly: true
      volumes:
      - name: config
        configMap:
          name: ${APP_NAME}-config
  volumeClaimTemplates:
  - metadata:
      name: data
      labels:
        app: ${APP_NAME}
    spec:
      accessModes: [&quot;ReadWriteOnce&quot;]
      storageClassName: ${STORAGE_CLASS}
      resources:
        requests:
          storage: ${STORAGE_SIZE}
```

### 6. Helm Chart Generation
