- API
  - Ingress resources are now available via `networking.k8s.io/v1beta1`. Ingress resources in `extensions/v1beta1` are deprecated and will no longer be served in v1.18. Existing persisted data is available via the new API group/version  ([#74057](https://github.com/kubernetes/kubernetes/pull/74057), [@liggitt](https://github.com/liggitt))

                expectedChecksum = expectedChecksum.substring(lastSpacePos + 1);
            } else {
                // remove everything after the first space (if available)
                int spacePos = expectedChecksum.indexOf(' ');

                if (spacePos != -1) {
                    expectedChecksum = expectedChecksum.substring(0, spacePos);
                }
            }

/// tip

Having the return model ensure that a value is always available and always `int` (not `None`) is very useful for the API clients, they can write much simpler code having this certainty.

server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip

The IP `0.0.0.0` is commonly used to mean that the program listens on all the IPs available in that machine/server.

///

The docs UI would also need the OpenAPI schema to declare that this API `server` is located at `/api/v1` (behind the proxy). For example:

```JSON hl_lines="4-8"
{

	if err != nil {
		writeErrorResponse(ctx, w, errorCodes.ToAPIErrWithErr(ErrBadRequest, InvalidArgument{
			Bucket: bucket,
			Err:    fmt.Errorf("replication resync status not available for %s (%s)", arn, err.Error()),
		}), r.URL)
		return
	}

	var rinfo ResyncTargetsInfo
	for tarn, st := range brs.TargetsMap {
		if arn != "" && tarn != arn {
			continue
		}
