Functions

func ComponentPod

func ComponentPod(container v1.Container, volumes map[string]v1.Volume, annotations map[string]string) v1.Pod

ComponentPod returns a Pod object from the container, volume and annotations specifications

func ComponentResources

func ComponentResources(cpu string) v1.ResourceRequirements

ComponentResources returns the v1.ResourceRequirements object needed for allocating a specified amount of the CPU

func DeepHashObject

func DeepHashObject(hasher hash.Hash, objectToWrite interface{})

DeepHashObject writes specified object to hash using the spew library which follows pointers and prints actual values of the nested objects ensuring the hash does not change when a pointer changes. Copied from k8s.io/kubernetes/pkg/util/hash/hash.go#DeepHashObject

func GetAPIServerProbeAddress

func GetAPIServerProbeAddress(endpoint *kubeadmapi.APIEndpoint) string

GetAPIServerProbeAddress returns the probe address for the API server

func GetControllerManagerProbeAddress

func GetControllerManagerProbeAddress(cfg *kubeadmapi.ClusterConfiguration) string

GetControllerManagerProbeAddress returns the kubernetes controller manager probe address

func GetEtcdProbeEndpoint

func GetEtcdProbeEndpoint(cfg *kubeadmapi.Etcd, isIPv6 bool) (string, int32, v1.URIScheme)

GetEtcdProbeEndpoint takes a kubeadm Etcd configuration object and attempts to parse the first URL in the listen-metrics-urls argument, returning an etcd probe hostname, port and scheme

func GetSchedulerProbeAddress

func GetSchedulerProbeAddress(cfg *kubeadmapi.ClusterConfiguration) string

GetSchedulerProbeAddress returns the kubernetes scheduler probe address

func GetUsersAndGroups

func GetUsersAndGroups() (*users.UsersAndGroups, error)

GetUsersAndGroups returns the local usersAndGroups, but first creates it in a thread safe way once.

func LivenessProbe

func LivenessProbe(host, path string, port int32, scheme v1.URIScheme) *v1.Probe

LivenessProbe creates a Probe object with a HTTPGet handler

func ManifestFilesAreEqual

func ManifestFilesAreEqual(path1, path2 string) (bool, string, error)

ManifestFilesAreEqual compares 2 files. It returns true if their contents are equal, false otherwise

func NewVolume

func NewVolume(name, path string, pathType *v1.HostPathType) v1.Volume

NewVolume creates a v1.Volume with a hostPath mount to the specified location

func NewVolumeMount

func NewVolumeMount(name, path string, readOnly bool) v1.VolumeMount

NewVolumeMount creates a v1.VolumeMount to the specified location

func PatchStaticPod

func PatchStaticPod(pod *v1.Pod, patchesDir string, output io.Writer) (*v1.Pod, error)

PatchStaticPod applies patches stored in patchesDir to a static Pod.

func ReadStaticPodFromDisk

func ReadStaticPodFromDisk(manifestPath string) (*v1.Pod, error)

ReadStaticPodFromDisk reads a static pod file from disk

func ReadinessProbe

func ReadinessProbe(host, path string, port int32, scheme v1.URIScheme) *v1.Probe

ReadinessProbe creates a Probe object with a HTTPGet handler

func RunComponentAsNonRoot

func RunComponentAsNonRoot(componentName string, pod *v1.Pod, usersAndGroups *users.UsersAndGroups, cfg *kubeadmapi.ClusterConfiguration) error

RunComponentAsNonRoot updates the pod manifest and the hostVolume permissions to run as non root.

func StartupProbe

func StartupProbe(host, path string, port int32, scheme v1.URIScheme, timeoutForControlPlane *metav1.Duration) *v1.Probe

StartupProbe creates a Probe object with a HTTPGet handler

func VolumeMapToSlice

func VolumeMapToSlice(volumes map[string]v1.Volume) []v1.Volume

VolumeMapToSlice returns a slice of volumes from a map's values

func VolumeMountMapToSlice

func VolumeMountMapToSlice(volumeMounts map[string]v1.VolumeMount) []v1.VolumeMount

VolumeMountMapToSlice returns a slice of volumes from a map's values

func WriteStaticPodToDisk

func WriteStaticPodToDisk(componentName, manifestDir string, pod v1.Pod) error

WriteStaticPodToDisk writes a static pod file to disk
