Types

type Cluster

type Cluster interface {
	// GetName gets the name weave-gitops has given this cluster.
	GetName() string
	// GetHost gets the host of the cluster - this should match what's set in the `rest.Config`s below
	GetHost() string
	// GetServerClient gets a un-impersonated client for this cluster
	GetServerClient() (client.Client, error)
	// GetUserClient gets an appropriately impersonated client for the user on this cluster
	GetUserClient(*auth.UserPrincipal) (client.Client, error)
	// GetServerClientset gets an un-impersonated clientset for this cluster
	GetServerClientset() (kubernetes.Interface, error)
	// GetUserClientset gets an appropriately impersonated clientset for the user on this cluster
	GetUserClientset(*auth.UserPrincipal) (kubernetes.Interface, error)
	// GetServerConig gets an un-impersonated rest config for this cluster.
	// Note that using this might bypass e.g. caches.
	GetServerConfig() (*rest.Config, error)
}

Cluster is an abstraction around a connection to a specific k8s cluster It's effectively a pair of (name, rest.Config), with some helpers
