Constants

const ResourceHashAnnotationKey = "cassandra.datastax.com/resource-hash"

const (
	// WatchNamespaceEnvVar is the constant for env variable WATCH_NAMESPACE
	// which is the namespace where the watch activity happens.
	// this value is empty if the operator is running with clusterScope.
	WatchNamespaceEnvVar = "WATCH_NAMESPACE"
)

Variables

var ErrNoNamespace = fmt.Errorf("namespace not found for current environment")

ErrNoNamespace indicates that a namespace could not be found for the current environment

var ErrRunLocal = fmt.Errorf("operator run mode forced to local")

ErrRunLocal indicates that the operator is set to run in local mode (this error is returned by functions that only work on operators running in cluster mode)

var ForceRunModeEnv = "OSDK_FORCE_RUN_MODE"

ForceRunModeEnv indicates if the operator should be forced to run in either local or cluster mode (currently only used for local mode)

Functions

func AddHashAnnotation

func AddHashAnnotation(r Annotated)

func AppendValuesToStringArrayIfNotPresent

func AppendValuesToStringArrayIfNotPresent(a []string, values ...string) []string

func DeepHashObject

func DeepHashObject(hasher hash.Hash, objectToWrite interface{})

DeepHashObject writes specified object to hash using the spew library which follows pointers and prints actual values of the nested objects ensuring the hash does not change when a pointer changes.

func ElementsMatch

func ElementsMatch(a interface{}, b interface{}) bool

func GenerateJKS

func GenerateJKS(ca *corev1.Secret, podname, dcname string) (jksblob []byte, err error)

func GetNewCAandKey

func GetNewCAandKey(leafdomain, namespace string) (keypem, certpem string, err error)

func GetOperatorNamespace

func GetOperatorNamespace() (string, error)

GetOperatorNamespace returns the namespace the operator should be running in.

func GetWatchNamespace

func GetWatchNamespace() (string, error)

GetWatchNamespace returns the namespace the operator should be watching for changes

func IndexOfString

func IndexOfString(a []string, v string) int

func MergeMap

func MergeMap(destination map[string]string, sources ...map[string]string) map[string]string

MergeMap will take two maps, merging the entries of the source map into destination map. If both maps share the same key then destination's value for that key will be overwritten with what's in source.

func RangeInt

func RangeInt(min, max, step int) []int

func RemoveValueFromStringArray

func RemoveValueFromStringArray(a []string, v string) []string

func ResourcesHaveSameHash

func ResourcesHaveSameHash(r1, r2 Annotated) bool

func SearchMap

func SearchMap(mapToSearch map[string]interface{}, key string) map[string]interface{}

SearchMap will recursively search a map looking for a key with a value of another map
