Types

type IngressGatewayValues

type IngressGatewayValues struct {
	Annotations              map[string]string
	Labels                   map[string]string
	NetworkPolicyLabels      map[string]string
	ExternalTrafficPolicy    *corev1.ServiceExternalTrafficPolicyType
	Image                    string
	IstiodNamespace          string
	LoadBalancerIP           *string
	MaxReplicas              *int
	MinReplicas              *int
	Namespace                string
	PriorityClassName        string
	TrustDomain              string
	ProxyProtocolEnabled     bool
	VPNEnabled               bool

	// Ports is a list of all Ports the istio-ingress gateways is listening on.
	// Port 15021 and 15000 cannot be used.
	Ports []corev1.ServicePort
}

IngressGatewayValues holds values for the istio-ingress chart. The only opened port is 15021.

type Interface

type Interface interface {
	component.DeployWaiter
	// AddIngressGateway adds another ingress gateway to the existing Istio deployer.
	AddIngressGateway(values IngressGatewayValues)
	// GetValues returns the configured values of the Istio deployer.
	GetValues() Values
}

Interface contains functions for an Istio deployer.

func NewIstio

func NewIstio(
	client client.Client,
	chartRenderer chartrenderer.Interface,
	values Values,
) Interface

NewIstio can be used to deploy istio's istiod in a namespace. Destroy does nothing.

type IstiodValues

type IstiodValues struct {
	// Enabled controls if `istiod` is deployed.
	Enabled bool
	// Namespace (a.k.a. Istio-System namespace) is the namespace `istiod` is deployed to.
	Namespace string
	// Image is the image used for the `istiod` deployment.
	Image string
	// PriorityClassName is the name of the priority class used for the Istiod deployment.
	PriorityClassName string
	// TrustDomain is the domain used for service discovery, e.g. `cluster.local`.
	TrustDomain string
	// Zones are the availability zones used for this `istiod` deployment.
	Zones []string
	// DualStack
	DualStack bool
}

IstiodValues contains configuration values for the Istiod component.

type Values

type Values struct {
	// Istiod are configuration values for the istiod chart.
	Istiod IstiodValues
	// IngressGateway are configuration values for ingress gateway deployments and objects.
	IngressGateway []IngressGatewayValues
	// NamePrefix can be used to prepend arbitrary identifiers to resources which are deployed to common namespaces.
	NamePrefix string
}

Values contains configuration values for the Istio component.
