The holiday season gave us a welcome break and an excellent opportunity to recharge our batteries. With this energy boost, we’ve set off into the new year, wishing you the best of luck and offering you the best of Kyma in its latest version, 2.10! Read on to find out what we have prepared for you.

Application Connectivity

From now Application Gateway will use the kyma-system Namespace instead of the kyma-integration Namespace. The Secrets related to the Namespace are not removed automatically in the process of upgrading Kyma to version 2.10. To remove them, you must run the migration script after successfully migrating from Kyma 2.9 to Kyma 2.10.

Eventing

NATS

We introduced a system account user to allow full leverage of the NATS CLI. For more information, read about Acquiring NATS server system account credentials.

Metrics

We exposed new metrics for backend latency.
We also introduced consistent naming for all metrics exposed by Eventing Publisher Proxy (EPP).
Read Kyma Eventing Metrics for more details.

Observability

Kiali

As announced in the blog post on Kiali deprecation, Kiali was deprecated with Kyma 2.8 and will be removed in Kyma 2.11.

Deprecation of Monitoring

We decided to deprecate the monitoring component based on Prometheus/Grafana. Please start the transition to alternative solutions now. The actual removal will happen in half a year or later, with Kyma 2.16 at the earliest. For more information, read this blog post.

Monitoring

Kyma 2.10 brings the update to the latest Prometheus images (version 2.40.7).

Telemetry

Logs

With this version of Kyma, we offer solutions to the following issues:

Traces

The first version of the new configurable tracing feature is available. Under the umbrella of the telemetry module, a new CRD TracePipeline is available as well. That new API will manage an OpenTelemetry Collector which supports you in integrating the trace aspects within a runtime into OTLP-based backends. For now, Basic Authentication is supported, and further ways of authentication will be added soon.
The Serverless and tracing modules were adjusted to the new approach.
Also, Istio got switched to the new approach. Thus, the trace propagation protocol was changed to the W3C Trace Context. Furthermore, the new Istio Telemetry API got activated to configure tracing settings selectively.

Serverless

With Kyma 2.10, we stop supporting the configuration of the previous Jaeger endpoint (at port 14268) as an option for Serverless Functions to send trace data. This endpoint was deprecated with Kyma 2.8 and replaced with one (at port 4318) that is compliant with Open Telemetry Protocol (OTLP). Functions don’t receive the previous endpoint as a configuration variable. Thus, if not rebuilt, they cannot send proper trace data. Functions built before Kyma 2.8 need to be rebuilt so that their trace data can be properly collected at the new OTLP endpoint introduced with the 2.8 release.

Service Mesh

Istio upgraded to 1.16.1

With this release, we upgraded Istio from 1.15.3 to 1.16.1. For more details on the changes, read the official Istio 1.16 Upgrade Notes.

Istio sidecar injection annotation deprecated

As of version 1.16 of Istio, the sidecar.istio.io/inject annotation was deprecated in favor of the sidecar.istio.io/inject label. To learn how to configure your Pods so that the Istio sidecar injection remains fully supported, read this blog post.

Support for XFF header

With this version of Kyma, we introduced Istio custom resource (CR) supporting the configuration of numTrustedProxies. Read about the Support for XFF with Istio to learn how to configure Istio CR and secure your workload on a forwarded client IP.
