Functions

func ConvertLabelToResourceType 

func ConvertLabelToResourceType(labelValue string) string

ConvertLabelToResourceType converts from kubernetes label value to Radius resource type i.e. it replaces the first occurrence of "-" with "/" in the given string and returns the result. Example: Applications.Core-containers becomes Applications.Core/Containers

func ConvertResourceTypeToLabelValue 

func ConvertResourceTypeToLabelValue(resourceType string) string

ConvertResourceTypeToLabelValue converts the given string to a value that Kubernetes allows i.e. it replaces the first occurrence of "/" with "-" and returns the modified string. Example: Applications.Core/containers becomes Applications.Core-Containers

func FindContourHTTPProxy 

func FindContourHTTPProxy(resources []rpv1.OutputResource) (*contourv1.HTTPProxy, rpv1.OutputResource)

FindContourHTTPProxyByLocalID searches through a slice of OutputResources to find a HTTPProxy resource.

func FindContourHTTPProxyByLocalID 

func FindContourHTTPProxyByLocalID(resources []rpv1.OutputResource, localID string) (*contourv1.HTTPProxy, rpv1.OutputResource)

FindContourHTTPProxyByLocalID searches through a slice of OutputResources to find a HTTPProxy resource with the given localID.

func FindDeployment 

func FindDeployment(resources []rpv1.OutputResource) (*appsv1.Deployment, rpv1.OutputResource)

FindDeployment searches through a slice of OutputResource objects and returns the first Deployment object and its associated OutputResource object.

func FindSecret 

func FindSecret(resources []rpv1.OutputResource) (*corev1.Secret, rpv1.OutputResource)

FindSecret iterates through a slice of OutputResource objects and returns the first Secret object found and its corresponding OutputResource object.

func FindService 

func FindService(resources []rpv1.OutputResource) (*corev1.Service, rpv1.OutputResource)

FindService searches through a slice of OutputResource objects and returns the first Service object found and the OutputResource object it was found in.

func GetShortenedTargetPortName 

func GetShortenedTargetPortName(name string) string

GetShortenedTargetPortName takes in a string and returns a shortened version of it by using a hashing algorithm. This generates a unique port name based on a resource id and can be used to link up a Service and Deployment.

func HashSecretData added in v0.26.4 

func HashSecretData(secretData map[string][]byte) string

HashSecretData hashes the data in a secret to produce a deterministic hash.

This can be used as a Kubernetes annotation to force a Deployment to redeploy pods when the secret changes.

func IsValidDaprObjectName 

func IsValidDaprObjectName(name string) bool

IsValidDaprObjectName checks if the given string is a valid Dapr object name and returns a boolean value.

func IsValidObjectName 

func IsValidObjectName(name string) bool

IsValidObjectName checks if the given string is a valid Kubernetes object name.

func MakeDescriptiveDaprLabels 

func MakeDescriptiveDaprLabels(application string, resource string, resourceType string) map[string]any

MakeDescriptiveLabels returns a map of the descriptive labels for a Kubernetes Dapr resource associated with a Radius resource. The descriptive labels are a superset of the selector labels.

func MakeDescriptiveLabels 

func MakeDescriptiveLabels(application string, resource string, resourceType string) map[string]string

MakeDescriptiveLabels returns a map of the descriptive labels for a Kubernetes resource associated with a Radius resource. The descriptive labels are a superset of the selector labels.

func MakeSelectorLabels 

func MakeSelectorLabels(application string, resource string) map[string]string

MakeSelectorLabels returns a map of labels suitable for a Kubernetes selector to identify a labeled Radius-managed Kubernetes object.

This function is used to generate the labels used by a Deployment to select its Pods. eg: the Deployment and Pods are the same resource.

func NormalizeDaprResourceName 

func NormalizeDaprResourceName(name string) string

NormalizeDaprResourceName normalizes resource name used for kubernetes Dapr resource name scoped in namespace. All name will be validated by swagger validation so that it does not get non-RFC1035 compliant characters. Therefore, this function will lowercase the name without allowed character validation. This function panics if the name is invalid. https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#rfc-1035-label-names

func NormalizeResourceName 

func NormalizeResourceName(name string) string

NormalizeResourceName normalizes resource name used for kubernetes resource name scoped in namespace. All name will be validated by swagger validation so that it does not get non-RFC1035 compliant characters. Therefore, this function will lowercase the name without allowed character validation. https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#rfc-1035-label-names
