Functions

func ChartNameByFile

func ChartNameByFile(name string) string

func ContainsIntInSlice

func ContainsIntInSlice(numbers []int, number int) bool

func ContainsStringInSlice

func ContainsStringInSlice(ss []string, str string) bool

func CreateOrUpdate

func CreateOrUpdate(ctx context.Context, r client.Client, o client.Object) (bool, error)

func GetCaFromSecret

func GetCaFromSecret(ctx context.Context, c client.Client, secretName, dataField, ns string) (crt []byte, err error)

func GetFromConfigMap

func GetFromConfigMap(ctx context.Context, c client.Client, name, ns, dataField string, o interface{}) (interface{}, error)

func IsMgmtCluster

func IsMgmtCluster(clusterName string) bool

func LastCondition

func LastCondition(conditons []metav1.Condition) metav1.Condition

func MergeMaps

func MergeMaps(a, b map[string]interface{}) map[string]interface{}

MergeMaps merges map b into given map a and returns the result. It allows overwrites of map values with flat values, and vice versa. This is copied from https://github.com/helm/helm/blob/v3.3.0/pkg/cli/values/options.go#L88, as the public chartutil.CoalesceTables function does not allow overwriting maps with flat values.

func ObjectKeyFromString

func ObjectKeyFromString(str string) client.ObjectKey

func Ordinalize

func Ordinalize(n int) string

Ordinalize takes an int and returns the ordinalized version of it. Eg. 1 --> 1st, 103 --> 103rd

func RandomString

func RandomString(length int) string

func ReleaseRevision

func ReleaseRevision(rel *release.Release) int

ReleaseRevision returns the revision of the given release.Release.

func RemoveDuplicateTaints

func RemoveDuplicateTaints(taints []corev1.Taint) []corev1.Taint

func Slugify

func Slugify(text string) string

Slugify a string. The result will only contain lowercase letters, digits and dashes. It will not begin or end with a dash, and it will not contain runs of multiple dashes.

It is NOT forced into being ASCII, but may contain any Unicode characters, with the above restrictions.

func Slugifyf

func Slugifyf(format string, a ...interface{}) string

Slugifyf slugfy a formated string

func ToUnstructured

func ToUnstructured(rawyaml []byte) ([]unstructured.Unstructured, error)

ToUnstructured takes a YAML and converts it to a list of Unstructured objects

func ValuesChecksum

func ValuesChecksum(values chartutil.Values) string

ValuesChecksum calculates and returns the SHA1 checksum for the given chartutil.Values.

Types

type LocalClusterType

type LocalClusterType int8

const (
	NonLocal LocalClusterType = iota
	NodeRetrieveError
	Kind
	Minikube
)

func IsLocalCluster

func IsLocalCluster(ctx context.Context, c client.Client) (LocalClusterType, error)

// Asserts whether the current cluster is local, and the kind of local cluster. Each type is mapped to the enum <LocalClusterType>.
