Functions

func GetMigrationLogs

func GetMigrationLogs() string

func GetMigrationStatus

func GetMigrationStatus(ctx context.Context, controllers types.ControllerConfig) (string, error)

func ObjectStorageAndPVCs

func ObjectStorageAndPVCs(config ekcoops.Config, controllers types.ControllerConfig)

ObjectStorageAndPVCs migrates the object storage from MinIO to Rook, and migrates PVCs from 'scaling' to the Rook storageclass

Types

type ClusterReadyResult

type ClusterReadyResult struct {
	MigrationReadyResult
	NrNodes         int `json:"nrNodes"`
	RequiredNrNodes int `json:"requiredNrNodes"`
}

ClusterReadyResult represents the status of the cluster readiness check, namely whether the total number of nodes in the cluster exceed or meet the minimum required number of nodes for the migration to start.

func IsClusterReady

func IsClusterReady(ctx context.Context, config ekcoops.Config, controllers types.ControllerConfig) (*ClusterReadyResult, error)

type MigrationReadyResult

type MigrationReadyResult struct {
	Ready  bool   `json:"ready"`
	Reason string `json:"reason"`
}

MigrationReadyResult represents the status of the migration readiness check, includes a reason, the total number of nodes in the cluster and the required number of nodes needed to start the migration.

func IsMigrationReady

func IsMigrationReady(ctx context.Context, config ekcoops.Config, controllers types.ControllerConfig) (*MigrationReadyResult, error)

IsMigrationReady returns if the cluster is ready to migrate storage. This is true if Ceph is setup/healthy, the ceph storageclass is present in the cluster, and the ceph object store user exists. This function also returns the current of number of nodes in the cluster.
