Types

type Resources

type Resources struct {
	// Root is the first level in the cluster resource hierarchy.
	// Each level in the hierarchy is a map[string]interface{} to the next level.
	// The levels are: namespaces/deployments/pods/containers.
	Root map[string]any
	// Labels maps a pod name to a map of labels key-values.
	Labels map[string]map[string]string
	// Annotations maps a pod name to a map of annotation key-values.
	Annotations map[string]map[string]string
	// Pod maps a pod name to its Pod info. The key is namespace/pod-name.
	Pod map[string]*corev1.Pod
	// CniPod
	CniPod map[string]*corev1.Pod
}

Resources defines a tree of cluster resource names.

func GetClusterResources

func (*Resources) ContainerRestarts

func (r *Resources) ContainerRestarts(namespace, pod, container string, isCniPod bool) int

ContainerRestarts returns the number of container restarts for the given container.

func (*Resources) IsDiscoveryContainer

func (r *Resources) IsDiscoveryContainer(clusterVersion, namespace, pod, container string) bool

IsDiscoveryContainer reports whether the given container is the Istio discovery container.

func (*Resources) PodIstioVersion

func (r *Resources) PodIstioVersion(namespace, pod string) string
