func Logr(l logr.Logger) lapi.Option

func MakePropertiesModification

func MakePropertiesModification(current, expected map[string]string) *lclient.GenericPropsModify

MakePropertiesModification returns the modification that need to be applied to update the current properties.

func PerClusterNodeCache

func PerClusterNodeCache(timeout time.Duration) lapi.Option

Client(s) pointing to the same URL will share a cache.

func PerClusterRateLimiter

func PerClusterRateLimiter(r rate.Limit, b int) lapi.Option

PerClusterRateLimiter creates a rate limiter for each distinct cluster.

Client(s) pointing to the same URL will share a rate limiter.

func UpdateLastApplyProperty

func UpdateLastApplyProperty(props map[string]string) map[string]string

UpdateLastApplyProperty ensures the LastApplyProperty is up-to-date.

Types

type Client

type Client struct {
	lapi.Client
}

Client is a LINSTOR client with convenience functions.

func NewClientForCluster

func NewClientForCluster(ctx context.Context, cl client.Client, namespace, clusterName, clientSecretName string, caRef *piraeusv1.CAReference, externalCluster *piraeusv1.LinstorExternalControllerRef, options ...lapi.Option) (*Client, error)

NewClientForCluster returns a LINSTOR client for a LINSTOR Controller managed by the operator.

func (*Client) CreateOrUpdateNode

func (c *Client) CreateOrUpdateNode(ctx context.Context, node lapi.Node) (*lapi.Node, error)

CreateOrUpdateNode ensures a node in LINSTOR matches the given node object.
