func CopyFile ¶ added in v1.1.0

func CopyFile(src, dest string) error

func CopyFileToDir ¶ added in v1.1.0

func CopyFileToDir(src, destDir string) (string, error)

CopyFileToDir copies file src to directory destDir. File src must exist. Directory destDir doesn't need exist nor its parent directories, they will be created if required. The destination file will have the same name as src. If that file already exists, it will be overwritten.

func DeepHashObject ¶ added in v1.3.0

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 DeepHashString ¶

func DeepHashString(obj interface{}) string

func FindEnvVar ¶ added in v1.2.0

func FindEnvVar(envVars []corev1.EnvVar, name string) *corev1.EnvVar

func FindEnvVarInContainer ¶ added in v1.2.0

func FindEnvVarInContainer(container *corev1.Container, name string) *corev1.EnvVar

func GetKey ¶

func GetKey(obj metav1.Object) client.ObjectKey

func GetMapNested ¶ added in v1.1.0

func GetMapNested(m map[string]interface{}, key string, keys ...string) (interface{}, bool)

GetMapNested gets the value at the given keys in the given map. It returns nil and false if the map does not contain all the keys.

func ListFiles ¶ added in v1.1.0

func ListFiles(root, pattern string) ([]string, error)

ListFiles lists all files whose names match pattern in root directory and its subdirectories.

func MergeMap ¶

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

MergeMap will take two or more maps, merging the entries of the sources map into a 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 MergeMapNested ¶ added in v1.1.0

func MergeMapNested(allowOverwrite bool, sources ...map[string]interface{}) (map[string]interface{}, error)

MergeMapNested will take two or more maps, merging the entries of the sources map into a destination map. If both maps share the same key then destination's value for that key will be merged with what's in source. The source maps are not modified. If allowOverwrite is false, an error is returned if the key already exists and its value is not nil.

func PutMapNested ¶ added in v1.1.0

func PutMapNested(allowOverwrite bool, m map[string]interface{}, val interface{}, key string, keys ...string) error

PutMapNested puts the given value in the given map at the given keys. When a key is not present, the entry is created on the fly; nested entries are always of type map[string]interface{} to allow for nested entries to be further inserted. If allowOverwrite is false, an error is returned if the key already exists and its value is not nil.

func ReadLines ¶ added in v1.1.0

func ReadLines(file string) ([]string, error)

ReadLines reads all lines in the given file.

func RemoveValue ¶

func RemoveValue(slice []string, value string) []string

func SliceContains ¶

func SliceContains(slice []string, s string) bool

func UnmarshalToMap ¶

func UnmarshalToMap(data []byte) (map[string]interface{}, error)
