Functions ¶

func ExtractContainerResourceValue ¶

func ExtractContainerResourceValue(fs *v1.ResourceFieldSelector, container *v1.Container) (string, error)

ExtractContainerResourceValue extracts the value of a resource in an already known container

func ExtractFieldPathAsString ¶

func ExtractFieldPathAsString(obj interface{}, fieldPath string) (string, error)

ExtractFieldPathAsString extracts the field from the given object and returns it as a string. The object must be a pointer to an API type.

Currently, this API is limited to supporting the fieldpaths:

1. metadata.name - The name of an API object 2. metadata.namespace - The namespace of an API object

func ExtractResourceValueByContainerName ¶

func ExtractResourceValueByContainerName(fs *v1.ResourceFieldSelector, pod *v1.Pod, containerName string) (string, error)

TODO: move the functions below to pkg/api/util/resources ExtractResourceValueByContainerName extracts the value of a resource by providing container name

func ExtractResourceValueByContainerNameAndNodeAllocatable ¶

func ExtractResourceValueByContainerNameAndNodeAllocatable(fs *v1.ResourceFieldSelector, pod *v1.Pod, containerName string, nodeAllocatable v1.ResourceList) (string, error)

ExtractResourceValueByContainerNameAndNodeAllocatable extracts the value of a resource by providing container name and node allocatable

func FormatMap ¶

func FormatMap(m map[string]string) (fmtStr string)

FormatMap formats map[string]string to a string.

func InternalExtractContainerResourceValue ¶

func InternalExtractContainerResourceValue(fs *api.ResourceFieldSelector, container *api.Container) (string, error)

TODO: remove this duplicate InternalExtractContainerResourceValue extracts the value of a resource in an already known container

func MergeContainerResourceLimits ¶

func MergeContainerResourceLimits(container *v1.Container,
	allocatable v1.ResourceList)

MergeContainerResourceLimits checks if a limit is applied for the container, and if not, it sets the limit to the passed resource list.
