Bug fixes

  • Before this update, connection was refused due to a missing gRPC port on the jaeger-query deployment. This issue resulted in transport: Error while dialing: dial tcp :16685: connect: connection refused error message. With this update, the Jaeger Query gRPC port (16685) is successfully exposed on the Jaeger Query service. (TRACING-3322)

  • Before this update, the wrong port was exposed for jaeger-production-query, resulting in refused connection. With this update, the issue is fixed by exposing the Jaeger Query gRPC port (16685) on the Jaeger Query deployment. (TRACING-2968)

  • Before this update, when deploying Service Mesh on single-node OpenShift clusters in disconnected environments, the Jaeger pod frequently went into the Pending state. With this update, the issue is fixed. (TRACING-3312)

  • Before this update, the Jaeger Operator pod restarted with the default memory value due to the reason: OOMKilled error message. With this update, this issue is fixed by removing the resource limits. (TRACING-3173)

Known issues

There are currently known issues:

  • Apache Spark is not supported.

  • The streaming deployment via AMQ/Kafka is unsupported on the IBM Z and IBM Power architectures.

Red Hat OpenShift distributed tracing platform (Tempo)

The Red Hat OpenShift distributed tracing platform (Tempo) is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

New features and enhancements

This release introduces the following enhancements for the distributed tracing platform (Tempo):

  • Support the operator maturity Level IV, Deep Insights, which enables upgrading, monitoring, and alerting of the TempoStack instances and the Tempo Operator.

  • Add Ingress and Route configuration for the Gateway.

  • Support the managed and unmanaged states in the TempoStack custom resource.

  • Expose the following additional ingestion protocols in the Distributor service: Jaeger Thrift binary, Jaeger Thrift compact, Jaeger gRPC, and Zipkin. When the Gateway is enabled, only the OpenTelemetry protocol (OTLP) gRPC is enabled.

  • Expose the Jaeger Query gRPC endpoint on the Query Frontend service.

  • Support multitenancy without Gateway authentication and authorization.

Bug fixes

  • Before this update, the Tempo Operator was not compatible with disconnected environments. With this update, the Tempo Operator supports disconnected environments. (TRACING-3145)

  • Before this update, the Tempo Operator with TLS failed to start on OpenShift Container Platform. With this update, the mTLS communication is enabled between Tempo components, the Operand starts successfully, and the Jaeger UI is accessible. (TRACING-3091)

  • Before this update, the resource limits from the Tempo Operator caused error messages such as reason: OOMKilled. With this update, the resource limits for the Tempo Operator are removed to avoid such errors. (TRACING-3204)

Known issues

There are currently known issues:

  • Currently, the custom TLS CA option is not implemented for connecting to object storage. (TRACING-3462)

  • Currently, when used with the Tempo Operator, the Jaeger UI only displays services that have sent traces in the last 15 minutes. For services that did not send traces in the last 15 minutes, traces are still stored but not displayed in the Jaeger UI. (TRACING-3139)

  • Currently, the distributed tracing platform (Tempo) fails on the IBM Z (s390x) architecture. (TRACING-3545)

  • Currently, the Tempo query frontend service must not use internal mTLS when Gateway is not deployed. This issue does not affect the Jaeger Query API. The workaround is to disable mTLS. (TRACING-3510)

    Workaround

    Disable mTLS as follows:

    1. Open the Tempo Operator configmap for editing by running the following command:

      $ oc edit configmap tempo-operator-manager-config -n openshift-tempo-operator (1)
      1 The project where the Tempo Operator is installed.

    2. Disable the mTLS in the Operator configuration by updating the YAML file:

      data:
  controller_manager_config.yaml: |
    featureGates:
      httpEncryption: false
      grpcEncryption: false
      builtInCertManagement:
        enabled: false

    3. Restart the Tempo Operator pod by running the following command:

      $ oc rollout restart deployment.apps/tempo-operator-controller -n openshift-tempo-operator

  • Missing images for running the Tempo Operator in restricted environments. The Red Hat OpenShift distributed tracing platform (Tempo) CSV is missing references to the operand images. (TRACING-3523)

    Workaround

    Add the Tempo Operator related images in the mirroring tool to mirror the images to the registry:

    kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
archiveSize: 20
storageConfig:
  local:

Technology Preview features

This release introduces support for the Red Hat OpenShift distributed tracing platform (Tempo) as a Technology Preview feature for Red Hat OpenShift distributed tracing platform.

The Red Hat OpenShift distributed tracing platform (Tempo) is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

The feature uses version 0.1.0 of the Red Hat OpenShift distributed tracing platform (Tempo) and version 2.0.1 of the upstream distributed tracing platform (Tempo) components.

You can use the distributed tracing platform (Tempo) to replace Jaeger so that you can use S3-compatible storage instead of ElasticSearch. Most users who use the distributed tracing platform (Tempo) instead of Jaeger will not notice any difference in functionality because the distributed tracing platform (Tempo) supports the same ingestion and query protocols as Jaeger and uses the same user interface.

If you enable this Technology Preview feature, note the following limitations of the current implementation:

  • The distributed tracing platform (Tempo) currently does not support disconnected installations. (TRACING-3145)

  • When you use the Jaeger user interface (UI) with the distributed tracing platform (Tempo), the Jaeger UI lists only services that have sent traces within the last 15 minutes. For services that have not sent traces within the last 15 minutes, those traces are still stored even though they are not visible in the Jaeger UI. (TRACING-3139)

Expanded support for the Tempo Operator is planned for future releases of the Red Hat OpenShift distributed tracing platform. Possible additional features might include support for TLS authentication, multitenancy, and multiple clusters. For more information about the Tempo Operator, see the Tempo community documentation.
