shouldnt this be available in Runner Config ?

[cnvergence]

Runner config calls the NewInfra, I'm adding this field to be able to differentiate the namespace used for Infra and Controller

[arkodg]

referring to

gateway/internal/infrastructure/runner/runner.go

Line 27 in ef50718

Config

[cnvergence]

controller namespace will be fetched from the Config

[arkodg]

so, we dont have access to the runner context anymore ? is that the issue ?

[zhaohuabing]

@arkodg runner context is not in the Infra, only the needed fields are passed down to the Infra structure.

func NewInfra(cli client.Client, cfg *config.Server) *Infra {
	var infraNamespace string
	if !cfg.EnvoyGateway.GatewayNamespaceMode() {
		infraNamespace = cfg.ControllerNamespace
	}
	return &Infra{
		Namespace:           infraNamespace,
		ControllerNamespace: cfg.ControllerNamespace,    # cfg is runner config
		DNSDomain:           cfg.DNSDomain,
		EnvoyGateway:        cfg.EnvoyGateway,
		Client:              New(cli),
		logger:              cfg.Logger.WithName(string(egv1a1.LogComponentInfrastructureRunner)),
	}
}

[zhaohuabing]

Can we also rename the Namespace field in the Infra structure to ControllerNamesapce to avoid confusion?

type Infra struct {
	// Namespace is the Namespace used for managed infra.
	Namespace string

	// DNSDomain is the dns domain used by k8s services. Defaults to "cluster.local".
	DNSDomain string

	// EnvoyGateway is the configuration used to startup Envoy Gateway.
	EnvoyGateway *egv1a1.EnvoyGateway

	// Client wrap k8s client.
	Client *InfraClient

	logger logging.Logger
}

LGTM thanks!
