Functions

func CSIEnabled

func CSIEnabled() bool

func CreateCsiConfigMap

func CreateCsiConfigMap(namespace string, clientset kubernetes.Interface) error

CreateCsiConfigMap creates an empty config map that will be later used to provide cluster configuration to ceph-csi.

func FormatCsiClusterConfig

func FormatCsiClusterConfig(
	clusterKey string, mons map[string]*cephconfig.MonInfo) (string, error)

FormatCsiClusterConfig returns a json-formatted string containing the cluster-to-mon mapping required to configure ceph csi.

func SaveClusterConfig

func SaveClusterConfig(
	clientset kubernetes.Interface, clusterNamespace string,
	clusterInfo *cephconfig.ClusterInfo, l sync.Locker) error

SaveClusterConfig updates the config map used to provide ceph-csi with basic cluster configuration. The clusterNamespace and clusterInfo are used to determine what "cluster" in the config map will be updated and and the clusterNamespace value is epxected to match the clusterID value that is provided to ceph-csi uses in the storage class. The locker l is typically a mutex and is used to prevent the config map from being updated for multiple clusters simultaneously.

func StartCSIDrivers

func StartCSIDrivers(namespace string, clientset kubernetes.Interface, ver *version.Info) error

func UpdateCsiClusterConfig

func UpdateCsiClusterConfig(
	curr, clusterKey string, mons map[string]*cephconfig.MonInfo) (string, error)

UpdateCsiClusterConfig returns a json-formatted string containing the cluster-to-mon mapping required to configure ceph csi.

func ValidateCSIParam

func ValidateCSIParam() error

Types
