1 - Concepts
Is a logical grouping of Workloads defined by the application labels that users apply to an object. In Istio it is defined by the Label App. See Istio Label Requirements.
It’s the name of the Application deployed in your environment. This name is provided by the Label App on the Workload.
A proxy that Istio starts for each pod in the service mesh. For more information see the Istio Envoy Documentation.
A health check performed by Envoy proxies, for inbound and outbound traffic: see membership_healthy and membership_total from Envoy documentation.
Istio object/configuration Type
This is the type specified in the Istio Config. This could be any of the following types: Gateway, Virtual Service, DestinationRule, ServiceEntry, Rule, Quota or QuotaSpecBinding.
For more information see the Istio Sidecar definition in Istio Sidecar Documentation.
It’s a user-created tag to identify a set of objects.
An empty label selector (that is, one with zero requirements) selects every object in the collection.
A null label selector (which is only possible for optional selector fields) selects no objects.
For example, Istio uses the Label App & Label Version on a Workload to specify the version and the application.
This is the ‘app’ label on an object. For more information, see Istio Label Requirements.
This is the ‘version’ label on an object. For more information, see Istio Label Requirements.
Namespaces are intended for use in environments with many users spread across multiple teams, or projects.
Namespaces are a way to divide cluster resources between multiple users.
A limited or fixed number or amount of resources.
Ensures that a specified number of pod replicas are running at any one time.
A Service is an abstraction which defines a logical set of Pods and a policy by which to access them. A Service is determined by a Label.
For more information see the Service Entry definition in Istio Service Entry Documentation.
For more information see the Virtual Service definition in Istio VirtualService Documentation.
For more information see the Istio Workload definition.
2 - Networking
For more information see the Destination definition in the Istio Glossary.
For more information see the Istio Destination Rule Documentation.
A communication endpoint is a type of communication network node. It is an interface exposed by a communicating party or by a communication channel.
It’s the percentage of errors in the traffic to a specific object for a Rate Interval.
For more information see the Gateway definition in the Istio Gateway Documentation.
Metrics on requests received by a given Workload, Service or Application.
Metrics on requests emitted by a given Workload or Application.
For more information see the Istio Port Documentation.
It’s an amount of time. By Default in Kiali last 10 minutes.
It’s an object that manages external access to the services in a cluster, typically HTTP.
For more information see the Source definition in the Istio Glossary.
