Data Plane

A minimal resource should have an empty spec.

apiVersion: install.tetrate.io/v1alpha1
kind: IngressGateway
metadata:
  name: bookinfo
  namespace: bookinfo
spec: {}

To configure infrastructure specific settings such as the service type, set the relevant field in kubeSpec. Remember that the installation API is an override API so if these fields are unset the operator will use sensible defaults. Only a subset of Kubernetes configuration is available.

EgressGateway and Tier1Gateway are configured in the same manner.

EgressGatewaySpec

EgressGatewaySpec defines the desired installed state of a single egress gateway for a given namespace in Service Bridge. Specifying a minimal EgressGatewaySpec with a hub will create a default gateway with sensible values.

Field	Description	Validation Rule
connectionDrainDuration	google.protobuf.Duration The amount of time the gateway will wait on shutdown for connections to complete before terminating the gateway. During this drain period, no new connections can be created but existing ones are allowed complete.	–
kubeSpec	tetrateio.api.install.kubernetes.KubernetesComponentSpec Configure Kubernetes specific settings.	–
revision	string Specifies the istio revision to reconcile with. If specified, TSB control plane operator will reconcile this gateway only if operator's revision matches with it. TSB data plane operator, which would be running only when TSB control plane operator is not configured a revision, will ignore revision field and will reconcile gateway as usual. Internally, this revision will guide to pick matching istio control plane for the gateway deployment https://istio.io/latest/blog/2020/multiple-control-planes/#configuring	–

IngressGatewaySpec

IngressGatewaySpec defines the desired installed state of a single ingress gateway for a given namespace in Service Bridge. Specifying a minimal IngressGatewaySpec with a hub will create a default gateway with sensible values.

Field	Description	Validation Rule
connectionDrainDuration	google.protobuf.Duration The amount of time the gateway will wait on shutdown for connections to complete before terminating the gateway. During this drain period, no new connections can be created but existing ones are allowed complete.	–
kubeSpec	tetrateio.api.install.kubernetes.KubernetesComponentSpec Configure Kubernetes specific settings.	–
revision	string Specifies the istio revision to reconcile with. If specified, TSB control plane operator will reconcile this gateway only if operator's revision matches with it. TSB data plane operator, which would be running only when TSB control plane operator is not configured a revision, will ignore revision field and will reconcile gateway as usual.

Tier1GatewaySpec

Tier1GatewaySpec defines the desired installed state of a single tier 1 gateway for a given namespace in Service Bridge. Specifying a minimal Tier1GatewaySpec with a hub will create a default gateway with sensible values.

Field	Description	Validation Rule
connectionDrainDuration	google.protobuf.Duration The amount of time the gateway will wait on shutdown for connections to complete before terminating the gateway. During this drain period, no new connections can be created but existing ones are allowed complete.	–
kubeSpec	tetrateio.api.install.kubernetes.KubernetesComponentSpec Configure Kubernetes specific settings.	–
revision	string Specifies the istio revision to reconcile with. If specified, TSB control plane operator will reconcile this gateway only if operator's revision matches with it. TSB data plane operator, which would be running only when TSB control plane operator is not configured a revision, will ignore revision field and will reconcile gateway as usual.
