Functions

func PodRequestsAndLimits

func PodRequestsAndLimits(pod *v1.Pod) (reqs, limits v1.ResourceList, err error)

PodRequestsAndLimits returns a dictionary of all defined resources summed up for all containers of the pod. If pod overhead is non-nil, the pod overhead is added to the total container resource requests and to the total container limits which have a non-zero quantity.

Types

type ClusterWorkloadReport

type ClusterWorkloadReport struct {
	ServerVersion string
	CreationTime  time.Time
	SourceName    string
	SourceType    string
	Nodes         []NodeSummary
	Namespaces    []corev1.Namespace
	Controllers   []ControllerResult
	Ingresses     []Ingress
}

ClusterWorkloadReport contains k8s workload resources report structure

func CreateResourceProviderFromAPI

func CreateResourceProviderFromAPI(ctx context.Context, dynamicClient dynamic.Interface, restMapper meta.RESTMapper, kube kubernetes.Interface, clusterName string) (*ClusterWorkloadReport, error)

CreateResourceProviderFromAPI creates a new ResourceProvider from an existing k8s interface

type ContainerResult

type ContainerResult struct {
	Name         string
	Image        string
	ImageID      string
	CreationTime time.Time
	Resource     ResourceResult
}

ContainerResult provides a list of validation messages for each container.

type ControllerResult

type ControllerResult struct {
	Kind           string
	Name           string
	Namespace      string
	Annotations    map[string]string
	Labels         map[string]string
	PodLabels      map[string]string
	PodAnnotations map[string]string
	UID            string
	ParentUID      string
	PodCount       float64
	Containers     []ContainerResult
}

ControllerResult provides a wrapper around a PodResult

type Ingress

type Ingress struct {
	Kind        string
	Name        string
	Namespace   string
	Annotations map[string]string
	Labels      map[string]string
	UID         string
	APIVersion  string
}

type NodeAllocatedResources

type NodeAllocatedResources struct {
	// Requests is the total requested resources of all pods in the node
	Requests v1.ResourceList
	// Requests is the total resource limits of all pods in the node
	Limits v1.ResourceList
}

NodeAllocatedResources describes node allocated resources.

type NodeSummary

type NodeSummary struct {
	Name               string
	Labels             map[string]string
	Annotations        map[string]string
	CreationTimestamp  time.Time
	Capacity           corev1.ResourceList
	Allocatable        corev1.ResourceList
	AllocatedLimits    corev1.ResourceList
	AllocatedRequests  corev1.ResourceList
	Utilization        NodeUtilization
	KubeletVersion     string
	KubeProxyVersion   string
	IsControlPlaneNode bool
}

NodeSummary gives highlevel overview of node informations

type NodeUtilization

type NodeUtilization struct {
	// CPURequestsFraction is a fraction of CPU, that is allocated.
	CPURequestsFraction float64 `json:"cpuRequestsFraction"`

	// CPULimitsFraction is a fraction of defined CPU limit, can be over 100%, i.e.
	// overcommitted.
	CPULimitsFraction float64 `json:"cpuLimitsFraction"`

	// MemoryRequestsFraction is a fraction of memory, that is allocated.
	MemoryRequestsFraction float64 `json:"memoryRequestsFraction"`

	// MemoryLimitsFraction is a fraction of defined memory limit, can be over 100%, i.e.
	// overcommitted.
	MemoryLimitsFraction float64 `json:"memoryLimitsFraction"`
}

type ResourceResult

type ResourceResult struct {
	Requests ResourcesInfo
	Limits   ResourcesInfo
}

ResourceResult provides resources information.

type ResourcesInfo

type ResourcesInfo struct {
	Memory string
	CPU    string
}

ResourcesInfo provides a request/limit item information.
