Prerequisites

Hardware and Software compatibility and requirements.

Istio

Before you install Kiali you must have already installed Istio along with its telemetry storage addon (i.e. Prometheus). You might also consider installing Istio’s optional tracing addon (i.e. Jaeger) and optional Grafana addon but those are not required by Kiali. Refer to the Istio documentation for details.

Service Mesh Compatibility

Each Kiali release is tested against the most recent Istio release. In general, Kiali tries to maintain compatibility with older Istio releases and Kiali versions later than those posted in the below table may work, but such combinations are not tested and will not be supported. Known incompatibilities are noted in the compatibility table below.

Istio Version Compatibility

Istio
Kiali
Notes
1.12 1.42.0 or later
1.11 1.38.1 to 1.41.x
1.10 1.34.1 to 1.37.x
1.9 1.29.1 to 1.33.x Istio 1.9 is out of support.
1.8 1.26.0 to 1.28.x Istio 1.8 removes all support for mixer/telemetry V1, as does Kiali 1.26.0. Use earlier versions of Kiali for mixer support.
1.7 1.22.1 to 1.25.x Istio 1.7 istioctl will no longer install Kiali. Use the Istio samples/addons all-in-one yaml or the Kiali Helm Chart for quick demo installs. Istio 1.7 is out of support.
1.6 1.18.1 to 1.21.x Istio 1.6 introduces CRD and Config changes, Kiali 1.17 is recommended for Istio < 1.6.

Browser Version Requirements

Kiali requires a modern web browser and supports the last two versions of Chrome, Firefox, Safari or Edge.

Hardware Requirements

Any machine capable of running a Kubernetes based cluster should also be able to run Kiali.

However, Kiali tends to grow in resource usage as your cluster grows. Usually the more namespaces and workloads you have in your cluster, the more memory you will need to allocate to Kiali.

Platform-specific requirements

OpenShift

If you are installing on OpenShift, you must grant the cluster-admin role to the user that is installing Kiali. If OpenShift is installed locally on the machine you are using, the following command should log you in as user system:admin which has this cluster-admin role:

$ oc login -u system:admin

Google Cloud Private Cluster

Private clusters on Google Cloud have network restrictions. Kiali needs your cluster’s firewall to allow access from the Kubernetes API to the Istio Control Plane namespace, for both the 8080 and 15000 ports.

To review the master access firewall rule:

gcloud compute firewall-rules list --filter="name~gke-${CLUSTER_NAME}-[0-9a-z]*-master"

To replace the existing rule and allow master access:

gcloud compute firewall-rules update <firewall-rule-name> --allow <previous-ports>,tcp:8080,tcp:15000
