Functions

func AddCephVersionLabelToDaemonSet added in v1.0.0 

func AddCephVersionLabelToDaemonSet(cephVersion version.CephVersion, d *apps.DaemonSet)

AddCephVersionLabelToDaemonSet adds a label reporting the Ceph version which Rook has detected is running in the DaemonSet's pods.

func AddCephVersionLabelToDeployment added in v1.0.0 

func AddCephVersionLabelToDeployment(cephVersion version.CephVersion, d *apps.Deployment)

AddCephVersionLabelToDeployment adds a label reporting the Ceph version which Rook has detected is running in the Deployment's pods.

func AddCephVersionLabelToJob added in v1.0.0 

func AddCephVersionLabelToJob(cephVersion version.CephVersion, j *batch.Job)

AddCephVersionLabelToJob adds a label reporting the Ceph version which Rook has detected is running in the Job's pods.

func AddCephVersionLabelToObjectMeta added in v1.1.0 

func AddCephVersionLabelToObjectMeta(cephVersion version.CephVersion, meta *metav1.ObjectMeta)

func AddVolumeMountSubPath added in v1.1.0 

func AddVolumeMountSubPath(podSpec *v1.PodSpec, volumeMountName string)

AddVolumeMountSubPath updates each init and regular container of the podspec such that each volume mount attached to a container is mounted under a subpath in the source volume. This is important because some daemons may not start if the volume mount directory is non-empty. When the volume is the root of an ext4 file system, one may find a "lost+found" directory.

func AdminFlags added in v1.0.0 

func AdminFlags(cluster *cephconfig.ClusterInfo) []string

AdminFlags returns the command line flags used for Ceph commands requiring admin authentication.

func AppLabels 

func AppLabels(appName, namespace string) map[string]string

AppLabels returns labels common for all Rook-Ceph applications which may be useful for admins. App name is the name of the application: e.g., 'rook-ceph-mon', 'rook-ceph-mgr', etc.

func CephVolumeMounts 

func CephVolumeMounts(confGeneratedInPod bool) []v1.VolumeMount

CephVolumeMounts returns the common list of Kubernetes volume mounts for Ceph containers. This function is only used for OSDs.

func CheckPodMemory added in v1.0.0 

func CheckPodMemory(resources v1.ResourceRequirements, cephPodMinimumMemory uint64) error

CheckPodMemory verify pod's memory limit is valid

func ContainerEnvVarReference added in v1.0.0 

func ContainerEnvVarReference(envVarName string) string

ContainerEnvVarReference returns a reference to a Kubernetes container env var of the given name which can be used in command or argument fields.

func DaemonEnvVars added in v1.0.0 

func DaemonEnvVars(image string) []v1.EnvVar

DaemonEnvVars returns the container environment variables used by all Ceph daemons.

func DaemonFlags added in v1.0.0 

func DaemonFlags(cluster *cephconfig.ClusterInfo, daemonID string) []string

DaemonFlags returns the command line flags used by all Ceph daemons.

func DaemonVolumeMounts added in v1.0.0 

func DaemonVolumeMounts(dataPaths *config.DataPathMap, keyringResourceName string) []v1.VolumeMount

DaemonVolumeMounts returns volume mounts which correspond to the DaemonVolumes. These volume mounts are shared by most all Ceph daemon containers, both init and standard. If keyring resource name is empty, there will be no keyring mounted in the container.

func DaemonVolumes added in v1.0.0 

func DaemonVolumes(dataPaths *config.DataPathMap, keyringResourceName string) []v1.Volume

DaemonVolumes returns the pod volumes used by all Ceph daemons. If keyring resource name is empty, there will be no keyring volume created from a secret.

func DaemonVolumesBase added in v1.1.0 

func DaemonVolumesBase(dataPaths *config.DataPathMap, keyringResourceName string) []v1.Volume

DaemonVolumesBase returns the common / static set of volumes.

func DaemonVolumesContainsPVC added in v1.1.0 

func DaemonVolumesContainsPVC(volumes []v1.Volume) bool

DaemonVolumesContainsPVC returns true if a volume exists with a volume source configured with a persistent volume claim.

func DaemonVolumesDataHostPath added in v1.1.0 

func DaemonVolumesDataHostPath(dataPaths *config.DataPathMap) []v1.Volume

DaemonVolumesDataHostPath returns HostPath volume source for daemon container data.

func DaemonVolumesDataPVC added in v1.1.0 

func DaemonVolumesDataPVC(pvcName string) v1.Volume

DaemonVolumesDataPVC returns a PVC volume source for daemon container data.

func PodLabels 

func PodLabels(appName, namespace, daemonType, daemonID string) map[string]string

PodLabels returns pod labels common to all Rook-Ceph pods which may be useful for admins. App name is the name of the application: e.g., 'rook-ceph-mon', 'rook-ceph-mgr', etc. Daemon type is the Ceph daemon type: "mon", "mgr", "osd", "mds", "rgw" Daemon ID is the ID portion of the Ceph daemon name: "a" for "mon.a"; "c" for "mds.c"

func PodLifeCycle added in v1.1.0 

func PodLifeCycle(dataDirHostPath string) *v1.Lifecycle

PodLifeCycle returns a pod lifecycle resource to execute actions before a pod starts

func PodVolumes 

func PodVolumes(dataDirHostPath, namespace string, confGeneratedInPod bool) []v1.Volume

PodVolumes fills in the volumes parameter with the common list of Kubernetes volumes for use in Ceph pods. This function is only used for OSDs.

func RookVolumeMounts 

func RookVolumeMounts(confGeneratedInPod bool) []v1.VolumeMount

RookVolumeMounts returns the common list of Kubernetes volume mounts for Rook containers. This function is only used by OSDs.

func StoredLogVolume added in v1.0.0 

func StoredLogVolume(HostLogDir string) v1.Volume

StoredLogVolume returns a pod volume sourced from the stored log files.

func StoredLogVolumeMount added in v1.0.0 

func StoredLogVolumeMount() v1.VolumeMount

StoredLogVolumeMount returns a pod volume sourced from the stored log files.

func ValidateCephVersionsBetweenLocalAndExternalClusters added in v1.1.0 

func ValidateCephVersionsBetweenLocalAndExternalClusters(context *clusterd.Context, namespace string, localVersion cephver.CephVersion) (cephver.CephVersion, error)

ValidateCephVersionsBetweenLocalAndExternalClusters makes sure an external cluster can be connected by checking the external ceph versions available and comparing it with the local image provided
