Functions

func GetContainerImages

func GetContainerImages(podTemplate *api.PodSpec) []string

GetContainerImages returns container image strings from the given pod spec.

Types

type Container

type Container struct {
	// Name of the container.
	Name string `json:"name"`

	// Image URI of the container.
	Image string `json:"image"`

	// List of environment variables.
	Env []EnvVar `json:"env"`
}

Container represents a docker/rkt/etc. container that lives in a pod.

type EnvVar

type EnvVar struct {
	// Name of the variable.
	Name string `json:"name"`

	// Value of the variable. May be empty if value from is defined.
	Value string `json:"value"`

	// Defined for derived variables. If non-null, the value is get from the reference.
	// Note that this is an API struct. This is intentional, as EnvVarSources are plain struct
	// references.
	ValueFrom *api.EnvVarSource `json:"valueFrom"`
}

EnvVar represents an environment variable of a container.

type Pod

type Pod struct {
	ObjectMeta common.ObjectMeta `json:"objectMeta"`
	TypeMeta   common.TypeMeta   `json:"typeMeta"`

	// Status of the Pod. See Kubernetes API for reference.
	PodPhase api.PodPhase `json:"podPhase"`

	// IP address of the Pod.
	PodIP string `json:"podIP"`

	// Count of containers restarts.
	RestartCount int32 `json:"restartCount"`

	// Pod metrics.
	Metrics *common.PodMetrics `json:"metrics"`
}

Pod is a presentation layer view of Kubernetes Pod resource. This means it is Pod plus additional augumented data we can get from other sources (like services that target it).

func ToPod

func ToPod(pod *api.Pod, metrics *common.MetricsByPod) Pod

ToPod transforms Kubernetes pod object into object returned by API.

type PodDetail

type PodDetail struct {
	ObjectMeta common.ObjectMeta `json:"objectMeta"`
	TypeMeta   common.TypeMeta   `json:"typeMeta"`

	// Status of the Pod. See Kubernetes API for reference.
	PodPhase api.PodPhase `json:"podPhase"`

	// IP address of the Pod.
	PodIP string `json:"podIP"`

	// Name of the Node this Pod runs on.
	NodeName string `json:"nodeName"`

	// Count of containers restarts.
	RestartCount int32 `json:"restartCount"`

	// List of container of this pod.
	Containers []Container `json:"containers"`

	// Pod metrics.
	Metrics *common.PodMetrics `json:"metrics"`
}

PodDetail is a presentation layer view of Kubernetes PodDetail resource. This means it is PodDetail plus additional augumented data we can get from other sources (like services that target it).

func GetPodDetail

func GetPodDetail(client k8sClient.Interface, heapsterClient client.HeapsterClient,
	namespace, name string) (*PodDetail, error)

GetPodDetail returns the details (PodDetail) of a named Pod from a particular namespace.

func ToPodDetail

func ToPodDetail(pod *api.Pod, metrics *common.MetricsByPod, configMaps *api.ConfigMapList) PodDetail

type PodList

type PodList struct {
	ListMeta common.ListMeta `json:"listMeta"`

	// Unordered list of Pods.
	Pods []Pod `json:"pods"`
}

ReplicationSetList contains a list of Pods in the cluster.

func CreatePodList

func CreatePodList(pods []api.Pod, pQuery *common.PaginationQuery,
	heapsterClient client.HeapsterClient) PodList

func GetPodList

func GetPodList(client k8sClient.Interface, heapsterClient client.HeapsterClient,
	nsQuery *common.NamespaceQuery, pQuery *common.PaginationQuery) (*PodList, error)

GetPodList returns a list of all Pods in the cluster.

func GetPodListFromChannels

func GetPodListFromChannels(channels *common.ResourceChannels, pQuery *common.PaginationQuery,
	heapsterClient client.HeapsterClient) (*PodList, error)

GetPodList returns a list of all Pods in the cluster reading required resource list once from the channels.
