+# Arnor
+
+Arnor 并不是一个具体的 app, 本 Chart 用于一些简单的项目部署, 使用者在填写了镜像及域名配置后, 即可快速拉起一个 HTTP 应用。
+
+## 使用步骤
+
+1. `helm repo add douban https://douban.github.io/charts/`
+2. `helm install my-app douban/arnor -f my-values.yaml`
+
+## 镜像
+
+- `image.repository`: 业务镜像仓库 (如 `registry.example.com/my-app`)
+- `image.tag`: 镜像版本号 (如 `v1.0.0`)
+
+## 主机名/域名路由
+
+Arnor 可分别启用 Ingress 或 Envoy Gateway HTTPRoute, 两者互不依赖。
+
+### Ingress 配置
+
+```yaml
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: app.example.com
+      paths:
+        - path: /
+          pathType: ImplementationSpecific
+  tls:
+    - secretName: app-example-com-tls
+      hosts:
+        - app.example.com
+```
+
+### HTTPRoute 配置
+
+```yaml
+httpRoute:
+  enabled: true
+  parentRefs:
+    - name: envoy-gateway-bundle
+      namespace: envoy-gateway-system
+  hostnames:
+    - app.example.com
+  extraPaths: []
+```
+
+## 挂载 Volume 与 Secret
+
+1. 在 `volumes` 中定义所需卷 (ConfigMap、Secret、PVC 等)。
+2. 在 `volumeMounts` 中将卷挂载到容器路径。
+
+示例:
+
+```yaml
+volumes:
+	- name: app-config
+		configMap:
+			name: my-config
+	- name: extra-secret
+		secret:
+			secretName: my-app-secret
+volumeMounts:
+	- name: app-config
+		mountPath: /etc/app
+	- name: extra-secret
+		mountPath: /var/run/secret
+		readOnly: true
+```
+
+## Vault 静态密钥注入
+
+启用 `vaultStaticSecret.enabled` 后, Chart 会负责拉取 Vault 中的静态密钥并注入到 Kubernetes Secret 中; 需要在 `volumes` 与 `volumeMounts` 手动引用该 Secret 才能在容器内使用。
+
+如果没有设置 `vaultStaticSecret.secretNameOverride`, secret 名字会与 fullname 完全相同, 也就是:
+
+```bash
+# release name 和 chart 同名时, 为 release name
+arnor
+# release name 和 chart 不同时, 为 release name - chart name
+my-app-arnor
+# 填写了 fullnameOverride 的情况下, 以 fullnameOverride 为准
+my-fullname
+# 详细逻辑请参考 _helpers.tpl 内的代码
+```
+
+```yaml
+vaultStaticSecret:
+  enabled: true
+  mount: kv-v2
+  path: secret/data
+  secretNameOverride: my-secret
+
+volumes:
+  - name: vault-secret
+    secret:
+      secretName: my-secret
+volumeMounts:
+  - name: vault-secret
+    mountPath: /vault/secrets
+    readOnly: true
+```
+
+> 最终路径与 `path` 完全一致, 请确认 Vault 中已存在该路径。
+
+## 完整示例
+
+```yaml
+image:
+  repository: registry.example.com/frontend
+  tag: v1.2.3
+
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: frontend.example.com
+      paths:
+        - path: /
+          pathType: ImplementationSpecific
+
+httpRoute:
+  enabled: false
+
+volumes:
+  - name: env-secret
+    secret:
+      secretName: frontend-env
+  - name: vault-secret
+    secret:
+      secretName: frontend
+volumeMounts:
+  - name: env-secret
+    mountPath: /app/.env
+    readOnly: true
+  - name: vault-secret
+    mountPath: /vault/data
+    readOnly: true
+
+vaultStaticSecret:
+  enabled: true
