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.
Functions ¶
func DockerInitPath ¶
DockerInitPath figures out the path of our dockerinit (which may be SelfPath())
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 ¶
GetCallerName introspects the call stack and returns the name of the function `depth` levels down in the stack.
func GetErrorMessage ¶
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 GitClone ¶
GitClone clones a repository into a newly created directory which will be under "docker-build-git"
func IsTimeout ¶
IsTimeout takes an error returned from (generally) the http package and determines if it is a timeout error.
func ReadDockerIgnore ¶
func ReadDockerIgnore(reader io.ReadCloser) ([]string, error)
ReadDockerIgnore reads a .dockerignore file and returns the list of file patterns to ignore. Note this will trim whitespace from each line as well as use GO's "clean" func to get the shortest/cleanest path for each.
func ReplaceOrAppendEnvValues ¶
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 ¶
TestDirectory creates a new temporary directory and returns its path. The contents of directory at path `templateDir` is copied into the new directory.
func ValidateContextDirectory ¶
ValidateContextDirectory checks if all the contents of the directory can be read and returns an error if some files can't be read symlinks which point to non-existing files don't trigger an error
