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 ParseEnvFile

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

ParseEnvFile reads a file with environment variables enumerated by lines

“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.

func ParseRestartPolicy

func ParseRestartPolicy(policy string) (container.RestartPolicy, error)

ParseRestartPolicy returns the parsed policy or an error indicating what is incorrect

func ReadKVStrings

func ReadKVStrings(files []string, override []string) ([]string, error)

ReadKVStrings reads a file of line terminated key=value pairs, and overrides any keys present in the file with additional pairs specified in the override parameter

Types

type ErrBadEnvVariable

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