Functions

func ContainerForStatus

func ContainerForStatus(pod *v1.Pod, cStatus v1.ContainerStatus) (v1alpha1.Container, error)

Convert a Kubernetes Pod and ContainerStatus into a simpler Container model to store in the engine state.

func ContainerStatusToRuntimeState

func ContainerStatusToRuntimeState(status v1alpha1.Container) v1alpha1.RuntimeStatus

func Pod

func Pod(ctx context.Context, pod *v1.Pod, ancestorUID types.UID, baselineRestarts int32) *v1alpha1.Pod

func PodConditions

func PodConditions(conditions []v1.PodCondition) []v1alpha1.PodCondition

func PodContainers

func PodContainers(ctx context.Context, pod *v1.Pod, containerStatuses []v1.ContainerStatus) []v1alpha1.Container

Convert a Kubernetes Pod into a list of simpler Container models to store in the engine state.

func PodStatusErrorMessages

func PodStatusErrorMessages(pod v1.Pod) []string

Pull out interesting error messages from the pod status

func PodStatusToString

func PodStatusToString(pod v1.Pod) string

copied from https://github.com/kubernetes/kubernetes/blob/aedeccda9562b9effe026bb02c8d3c539fc7bb77/pkg/kubectl/resource_printer.go#L692-L764 to match the status column of `kubectl get pods`

func SpanIDForPod

func SpanIDForPod(mn model.ManifestName, podID k8s.PodID) logstore.SpanID

SpanIDForPod creates a span ID for a given pod associated with a manifest.

Generally, a given Pod is only referenced by a single manifest, but there are rare occasions where it can be referenced by multiple. If the span ID is not unique between them, things will behave erratically.
