Specify default images as var instead of const so that they can be overridden with the Go linker's -X flag. This allows users to easily build images with a different opinionated set of images without having to specify them manually in charts/manifests which can make upgrades more manually challenging.

Functions

func CSIEnabled

func CSIEnabled() bool

func CreateCSISecrets added in v1.1.3

func CreateCSISecrets(context *clusterd.Context, clusterName string, ownerRef *metav1.OwnerReference) error

CreateCSISecrets creates all the Kubernetes CSI Secrets

func CreateCsiConfigMap added in v1.1.0

func CreateCsiConfigMap(namespace string, clientset kubernetes.Interface) (*v1.ConfigMap, error)

CreateCsiConfigMap creates an empty config map that will be later used to provide cluster configuration to ceph-csi. If a config map already exists, it will return it.

func DeleteCsiConfigMap added in v1.2.0

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

func FormatCsiClusterConfig added in v1.1.0

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 added in v1.1.0

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 expected 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 StopCSIDrivers added in v1.2.0

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

func UpdateCsiClusterConfig added in v1.1.0

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
