# Gemma 4 E2B — Kubernetes Security Expert

A QLoRA fine-tuned version of [Gemma 4 E2B Instruct](https://huggingface.co/google/gemma-4-e2b-it) specialized in **kubernetes security**.
Specialized in **Kubernetes security**: RBAC design, Pod Security Standards, network policies, admission controllers, etcd encryption, and multi-tenant cluster hardening.

Part of the [rezaduty cybersecurity model family](https://huggingface.co/rezaduty).

## Expertise

- RBAC least-privilege design and audit logging
- Pod Security Standards (Restricted, Baseline, Privileged)
- Network policies and service mesh security (Istio/Linkerd)
- Admission controllers: OPA Gatekeeper, Kyverno, Falco
- Secrets encryption at rest and external secrets management
- Supply-chain security: image signing, SBOM, admission control

## Usage

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel
import torch

base_model = "google/gemma-4-e2b-it"
adapter    = "rezaduty/gemma4-e2b-kubernetes-security"

tokenizer = AutoTokenizer.from_pretrained(adapter)
model = AutoModelForCausalLM.from_pretrained(
    base_model, torch_dtype=torch.bfloat16, device_map="auto"
)
model = PeftModel.from_pretrained(model, adapter)

messages = [
    {"role": "system", "content": [{"type": "text", "text": "You are an expert in Kubernetes security. You provide deep answers on RBAC, Pod Security, network policies, admission controllers, secrets management, and cluster hardening."}]},
    {"role": "user",   "content": [{"type": "text", "text": "Your question here"}]},
]
inputs = tokenizer.apply_chat_template(
    messages, tokenize=True, add_generation_prompt=True, return_tensors="pt"
).to(model.device)
output = model.generate(inputs, max_new_tokens=512, temperature=0.7, top_p=0.9)
print(tokenizer.decode(output[0][inputs.shape[-1]:], skip_special_tokens=True))
```
