Functions

func Contains

func Contains(collection []string, key string) bool

Contains checks if the specified string (key) is present in the specified collection.

func Convert

func Convert(src, target interface{}) error

Convert converts a struct (src) to another one (target) using yaml marshalling/unmarshalling. If the structure are not compatible, this will throw an error as the unmarshalling will fail.

func ConvertByJSON

func ConvertByJSON(src, target interface{}) error

ConvertByJSON converts a struct (src) to another one (target) using json marshalling/unmarshalling. If the structure are not compatible, this will throw an error as the unmarshalling will fail.

func CopyMap

func CopyMap(m map[string]string) map[string]string

CopyMap creates an exact copy of the provided string-to-string map

func CopySlice

func CopySlice(s []string) []string

CopySlice creates an exact copy of the provided string slice

func FilterString

func FilterString(data map[string][]string) string

FilterString returns a json representation of the specified map that is used as filter for docker.

func FilterStringSet

func FilterStringSet(s map[string]bool, f func(x string) bool) map[string]bool

FilterStringSet accepts a string set `s` (in the form of `map[string]bool`) and a filtering function `f` and returns a string set containing only the strings `x` for which `f(x) == true`

func LabelFilter

func LabelFilter(key, value string) map[string][]string

LabelFilter returns a label map representation of the specifed couple (key,value) that is used as filter for docker.

func LabelFilterString

func LabelFilterString(key, value string) string

LabelFilterString returns a label json string representation of the specifed couple (key,value) that is used as filter for docker.

func Merge

func Merge(coll1, coll2 []string) []string

Merge performs a union of two string slices: the result is an unordered slice that includes every item from either argument exactly once

Types

type InParallel

type InParallel struct {
	// contains filtered or unexported fields
}

InParallel holds a pool and a waitgroup to execute tasks in parallel and to be able to wait for completion of all tasks.

func (*InParallel) Add

func (i *InParallel) Add(task func() error)

Add runs the specified task in parallel and adds it to the waitGroup.

func (*InParallel) Wait

func (i *InParallel) Wait() error

Wait waits for all tasks to complete and returns the latest error encountered if any.
