Constants ¶

const RestrictedNameChars = `[a-zA-Z0-9][a-zA-Z0-9_.-]`

RestrictedNameChars collects the characters allowed to represent a name, normally used to validate container and volume names.

Variables ¶

var RestrictedNamePattern = regexp.MustCompile(`^/?` + RestrictedNameChars + `+$`)

RestrictedNamePattern is a regular expression to validate names against the collection of restricted characters.

var RestrictedVolumeNamePattern = regexp.MustCompile(`^` + RestrictedNameChars + `+$`)

RestrictedVolumeNamePattern is a regular expression to validate volume names against the collection of restricted characters.

func DisableDebug()

DisableDebug sets the DEBUG env var to false and makes the logger to log at info level.

func EnableDebug ¶

func ExperimentalBuild ¶

func ExperimentalBuild() bool

func GetCallerName ¶

func GetCallerName(depth int) string

GetCallerName introspects the call stack and returns the name of the function `depth` levels down in the stack.

func IsDebugEnabled ¶

func IsDebugEnabled() bool

IsDebugEnabled checks whether the debug flag is set or not.

func IsProcessAlive ¶

func IsProcessAlive(pid int) bool

IsProcessAlive returns true if process with a given pid is running.

func KillProcess ¶

func KillProcess(pid int)

KillProcess force-stops a process.

func ReplaceOrAppendEnvValues ¶

func ReplaceOrAppendEnvValues(defaults, overrides []string) []string

ReplaceOrAppendEnvValues returns the defaults with the overrides either replaced by env key or appended to the list

func TestDirectory ¶

func TestDirectory(templateDir string) (dir string, err error)
