Functions

func ConvertKVStringsToMap

func ConvertKVStringsToMap(values []string) map[string]string

ConvertKVStringsToMap converts ["key=value"] to {"key":"value"}

func ConvertKVStringsToMapWithNil

func ConvertKVStringsToMapWithNil(values []string) map[string]*string

ConvertKVStringsToMapWithNil converts ["key=value"] to {"key":"value"} but set unset keys to nil - meaning the ones with no "=" in them. We use this in cases where we need to distinguish between

FOO=  and FOO

where the latter case just means FOO was mentioned but not given a value

func ConvertPortToPortConfig(
	port nat.Port,
	portBindings map[nat.Port][]nat.PortBinding,
) ([]swarm.PortConfig, error)

func ParseEnvFile

func ParseEnvFile(filename string) ([]string, error)

“Environment variable names used by the utilities in the Shell and Utilities volume of IEEE Std 1003.1-2001 consist solely of uppercase letters, digits, and the '_' (underscore) from the characters defined in Portable Character Set and do not begin with a digit. *But*, other characters may be permitted by an implementation; applications shall tolerate the presence of such names.” -- http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html

As of #16585, it's up to application inside docker to validate or not environment variables, that's why we just strip leading whitespace and nothing more.
