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.

Functions ¶

func DisableDebug ¶

func DisableDebug()

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

func DockerInitPath ¶

func DockerInitPath(localCopy string) string

DockerInitPath figures out the path of our dockerinit (which may be SelfPath())

func EnableDebug ¶

func EnableDebug()

EnableDebug sets the DEBUG env var to true and makes the logger to log at debug level.

func ExperimentalBuild ¶

func ExperimentalBuild() bool

ExperimentalBuild is a stub which always returns false for builds that do not include the "experimental" build tag

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 GetErrorMessage ¶

func GetErrorMessage(err error) string

GetErrorMessage returns the human readable message associated with the passed-in error. In some cases the default Error() func returns something that is less than useful so based on its types this func will go and get a better piece of text.

func IsDebugEnabled ¶

func IsDebugEnabled() bool

IsDebugEnabled checks whether the debug flag is set or not.

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 SelfPath ¶

func SelfPath() string

SelfPath figures out the absolute path of our own binary (if it's still around).

func TestDirectory ¶

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

TestDirectory creates a new temporary directory and returns its path. The contents of directory at path `templateDir` is copied into the new directory.
