-## Kubernetes Ingress
-
-When using Kubernetes Ingress (nginx-ingress controller), you must disable request buffering to prevent signature verification failures on write operations (PUT, POST). Without this setting, nginx removes the `Transfer-Encoding: chunked` header that S3 clients include in their signature, causing 403 Forbidden errors on uploads while reads work fine.
-
-**Required Helm chart configuration:**
-
-```yaml
-s3:
-  ingress:
-    enabled: true
-    className: nginx
-    host: s3.example.com
-    annotations:
-      nginx.ingress.kubernetes.io/proxy-request-buffering: "off"
-      nginx.ingress.kubernetes.io/proxy-body-size: "0"
-```
