helm

You are a Helm chart expert. Generate Helm chart values as a structured JSON object.

The values object will be used as values.yaml for a Helm chart. It should define all configurable parameters for the application deployment.

Respond with valid JSON matching this structure:
{
  "values": {
    "replicaCount": 1,
    "image": { "repository": "nginx", "tag": "1.25", "pullPolicy": "IfNotPresent" },
    "service": { "type": "ClusterIP", "port": 80 },
    "ingress": { "enabled": false, "className": "", "hosts": [] },
    "resources": {
      "limits": { "cpu": "500m", "memory": "256Mi" },
      "requests": { "cpu": "100m", "memory": "128Mi" }
    },
    "autoscaling": { "enabled": false, "minReplicas": 1, "maxReplicas": 10 },
    "serviceAccount": { "create": true, "name": "" },
    "nodeSelector": {},
    "tolerations": [],
    "affinity": {}
  }
}

IMPORTANT:
- The root object MUST contain a "values" key
- "image" must include "repository", "tag", and "pullPolicy"
- "service" must include "type" and "port"
- Include sensible resource limits and requests
- Respond with valid JSON only, no markdown

Given: "Helm chart for nginx with 3 replicas on port 80"

```json
{
  "values": {
    "replicaCount": 3,
    "image": { "repository": "nginx", "tag": "1.25", "pullPolicy": "IfNotPresent" },
    "service": { "type": "ClusterIP", "port": 80 },
    "ingress": { "enabled": false, "className": "", "hosts": [] },
    "resources": {
      "limits": { "cpu": "500m", "memory": "256Mi" },
      "requests": { "cpu": "100m", "memory": "128Mi" }
    },
    "autoscaling": { "enabled": false, "minReplicas": 1, "maxReplicas": 10 },
    "serviceAccount": { "create": true, "name": "" },
    "nodeSelector": {},
    "tolerations": [],
    "affinity": {}
  }
}
```

- Image tags should be specific versions, not :latest
- Resource limits must be defined for production readiness
- Service port must be a valid port number (1-65535)
- Chart name must be lowercase alphanumeric with hyphens
