The Kiali observability console is only supported on the two most recent releases of the Chrome, Edge, Firefox, or Safari browsers.

This release only supports the following Mixer adapter:

Traffic Management - Control the flow of traffic and API calls between services, make calls more reliable, and make the network more robust in the face of adverse conditions.

Service Identity and Security - Provide services in the mesh with a verifiable identity and provide the ability to protect service traffic as it flows over networks of varying degrees of trustworthiness.

Policy Enforcement - Apply organizational policy to the interaction between services, ensure access policies are enforced and resources are fairly distributed among consumers. Policy changes are made by configuring the mesh, not by changing application code.

Telemetry - Gain understanding of the dependencies between services and the nature and flow of traffic between them, providing the ability to quickly identify issues.

The Kubernetes Container Network Interface (CNI) plug-in is always on.

The control plane is configured for multitenancy by default. Single tenant, cluster-wide control plane configurations are deprecated.

The Elasticsearch, Jaeger, Kiali, and Service Mesh Operators are installed from OperatorHub.

You can create and specify control plane templates.

Automatic route creation was removed from this release.

Istio-14743 Due to limitations in the version of Istio that this release of Red Hat OpenShift Service Mesh is based on, there are several applications that are currently incompatible with Service Mesh. See the linked community issue for details.

MAISTRA-858 The following Envoy log messages describing deprecated options and configurations associated with Istio 1.1.x are expected:

MAISTRA-681 and KIALI-2686 When the control plane has many namespaces, it can lead to performance issues.

MAISTRA-622 In Maistra 0.12.0/TP12, permissive mode does not work. The user has the option to use Plain text mode or Mutual TLS mode, but not permissive.

MAISTRA-465 The Maistra operator fails to create a service for operator metrics.

MAISTRA-453 If you create a new project and deploy pods immediately, sidecar injection does not occur. The operator fails to add the maistra.io/member-of before the pods are created, therefore the pods must be deleted and recreated for sidecar injection to occur.

MAISTRA-348 To access a TCP service by using the ingress gateway on a port other than 80 or 443, use the service hostname provided by the AWS load balancer rather than the OpenShift router.

$ oc -n istio-system get service istio-ingressgateway -o jsonpath='{.status.loadBalancer.ingress[0].hostname}'

MAISTRA-193 Unexpected console info messages are visible when health checking is enabled for citadel.

MAISTRA-158 Applying multiple gateways referencing the same hostname will cause all gateways to stop functioning.

MAISTRA-806 Evicted Istio Operator Pod causes mesh and CNI not to deploy.

KIALI-3262 In the Kiali console, when you click on Distributed Tracing in the navigation or on a Traces tab, you are asked to accept the certificate, and then asked to provide your OpenShift login credentials. This happens due to an issue with how the framework displays the Trace pages in the Console. The Workaround is to open the URL for the Jaeger console in another browser window and log in. Then you can view the embedded tracing pages in the Kiali console.

KIALI-3239 If a Kiali Operator pod has failed with a status of “Evicted” it blocks the Kiali operator from deploying. The workaround is to delete the Evicted pod and redeploy the Kiali operator.

KIALI-3118 After changes to the ServiceMeshMemberRoll, for example adding or removing projects, the Kiali pod restarts and then displays errors on the Graph page while the Kiali pod is restarting.

KIALI-3070 This bug only affects custom dashboards, not the default dashboards. When you select labels in metrics settings and refresh the page, your selections are retained in the menu but your selections are not displayed on the charts.

KIALI-2206 When you are accessing the Kiali console for the first time, and there is no cached browser data for Kiali, the “View in Grafana” link on the Metrics tab of the Kiali Service Details page redirects to the wrong location. The only way you would encounter this issue is if you are accessing Kiali for the first time.

KIALI-507 Kiali does not support Internet Explorer 11. This is because the underlying frameworks do not support Internet Explorer. To access the Kiali console, use one of the two most recent versions of the Chrome, Edge, Firefox or Safari browser.

MAISTRA-684 The default Jaeger version in the istio-operator is 1.12.0, which does not match Jaeger version 1.13.1 that shipped in Red Hat OpenShift Service Mesh 0.12.TechPreview.

MAISTRA-572 Jaeger cannot be used with Kiali. In this release Jaeger is configured to use the OAuth proxy, but is also only configured to work through a browser and does not allow service access. Kiali cannot properly communicate with the Jaeger endpoint and it considers Jaeger to be disabled. See also TRACING-591.

MAISTRA-357 In OpenShift 4 Beta on AWS, it is not possible, by default, to access a TCP or HTTPS service through the ingress gateway on a port other than port 80. The AWS load balancer has a health check that verifies if port 80 on the service endpoint is active.

KIALI-3096 Runtime metrics fail in Service Mesh. There is an oauth filter between the Service Mesh and Prometheus, requiring a bearer token to be passed to Prometheus before access will be granted. Kiali has been updated to use this token when communicating to the Prometheus server, but the application metrics are currently failing with 403 errors.

OSSM-90 Traces not available on the service details page.

OSSM-92 Cancelling unsaved changes on the VS/DR YAML edit page does not cancel the changes.

OSSM-93 IstioConfigList can’t filter by two or more names.

OSSM-99 Workloads generated from direct Pod without labels may crash Kiali.
