func (*Operation) InitializeMonitoringClient

func (o *Operation) InitializeMonitoringClient() error

InitializeMonitoringClient will read the Prometheus ingress auth and tls secrets from the Seed cluster, which are containing the cert to secure the connection and the credentials authenticate against the Shoot Prometheus. With those certs and credentials, a Prometheus client API will be created and attached to the existing Operation object.

func (*Operation) InitializeSeedClients

func (o *Operation) InitializeSeedClients() error

InitializeSeedClients will use the Garden Kubernetes client to read the Seed Secret in the Garden cluster which contains a Kubeconfig that can be used to authenticate against the Seed cluster.
