+# Kubernetes development mTLS overlay
+
+该 Overlay 在 base 资源之上启用 Controller 控制面 mTLS，并启动一个固定身份的 Gateway
+和 Checker。它只用于开发或预发布的单副本控制面验证，不是生产弹性身份方案。
+
+## Prepare certificates
+
+先生成未提交的开发证书。输出目录必须为空；生成器的 `controller` 证书包含
+`DNS:controller`，Overlay 中的客户端也只拨号 `controller:8443`。
+
+```powershell
+./scripts/generate-local-controlplane-certs.ps1
+kubectl apply -f deploy/kubernetes/base/namespace.yaml
+```
+
+将生成的三组证书写入 Kubernetes Secret。下面的命令可重复执行，只更新对应 Secret：
+
+```powershell
+kubectl -n proxy-pool create secret generic proxy-pool-controlplane-server-tls `
+  --from-file=tls.crt=deploy/.control-plane-tls/controller/tls.crt `
+  --from-file=tls.key=deploy/.control-plane-tls/controller/tls.key `
+  --from-file=ca.crt=deploy/.control-plane-tls/controller/ca.crt `
+  --dry-run=client -o yaml | kubectl apply -f -
+
+kubectl -n proxy-pool create secret generic proxy-pool-controlplane-gateway-tls `
+  --from-file=tls.crt=deploy/.control-plane-tls/gateway-a/tls.crt `
+  --from-file=tls.key=deploy/.control-plane-tls/gateway-a/tls.key `
+  --from-file=ca.crt=deploy/.control-plane-tls/gateway-a/ca.crt `
+  --dry-run=client -o yaml | kubectl apply -f -
+
+kubectl -n proxy-pool create secret generic proxy-pool-controlplane-checker-tls `
+  --from-file=tls.crt=deploy/.control-plane-tls/checker-a/tls.crt `
+  --from-file=tls.key=deploy/.control-plane-tls/checker-a/tls.key `
+  --from-file=ca.crt=deploy/.control-plane-tls/checker-a/ca.crt `
+  --dry-run=client -o yaml | kubectl apply -f -
+```
+
+另行从私密配置系统创建 `proxy-pool-secrets`。可参考 base 目录的
+`secret.example.yaml`，但不要把实际数据库、Redis、Provider 或 API 凭据写入 Git。
+
+## Deploy
+
+```powershell
+kubectl apply -k deploy/kubernetes/overlays/development-mtls
+kubectl -n proxy-pool rollout status deployment/proxy-controller --timeout=5m
+kubectl -n proxy-pool rollout status deployment/proxy-gateway --timeout=5m
+kubectl -n proxy-pool rollout status deployment/proxy-checker --timeout=5m
+```
+
+Overlay 的 Gateway 固定为 `worker_id=gateway-a`，Checker 固定为
+`checker_id=checker-a`，并把 Gateway HPA 限制为 `minReplicas=maxReplicas=1`。
+因此不得在此 Overlay 上增加副本数或放宽 HPA；重复使用同一 Worker 身份会破坏
+session、ownership 和证书角色边界。
+
+生产环境需要由工作负载身份系统为每个副本签发独立、可轮换的证书，并将该副本的
+身份注入 `worker_id`、`instance_id`、Gateway Client TLS 或 Checker Client TLS。
