Functions

func CreateInjectedFilesRemovalScript

func CreateInjectedFilesRemovalScript(files []string, scriptName string) (string, error)

CreateInjectedFilesRemovalScript creates a shell script that contains truncation of all files we injected into the container. The path to the script is returned. When the scriptName is provided, it is also truncated together with all secrets.

func ExpandInjectedFiles

func ExpandInjectedFiles(injections api.InjectionList) ([]string, error)

ExpandInjectedFiles returns a flat list of all files that are injected into a container. All files from nested directories are returned in the list.

func FixInjectionsWithRelativePath

func FixInjectionsWithRelativePath(workdir string, injections *api.InjectionList)

FixInjectionsWithRelativePath fixes the injections that does not specify the destination directory or the directory is relative to use the provided working directory.

func GenerateLabelsFromConfig

func GenerateLabelsFromConfig(labels map[string]string, config *api.Config, namespace string) map[string]string

GenerateLabelsFromConfig generate the labels based on build s2i Config

func GenerateLabelsFromSourceInfo

func GenerateLabelsFromSourceInfo(labels map[string]string, info *api.SourceInfo, namespace string) map[string]string

GenerateLabelsFromSourceInfo generate the labels based on the source repository informations.

func GenerateOutputImageLabels

func GenerateOutputImageLabels(info *api.SourceInfo, config *api.Config) map[string]string

GenerateOutputImageLabels generate the labels based on the s2i Config and source repository informations.

func HandleInjectionError

func HandleInjectionError(p api.InjectPath, err error) error

HandleInjectionError handles the error caused by injection and provide reasonable suggestion to users.

func IsTimeoutError

func IsTimeoutError(e error) bool

IsTimeoutError checks if the provided error is timeout.

func ReadEnvironmentFile

func ReadEnvironmentFile(path string) (map[string]string, error)

ReadEnvironmentFile reads the content for a file that contains a list of environment variables and values. The key-pairs are separated by a new line character. The file can also have comments (both '#' and '//' are supported).

func TimeoutAfter

func TimeoutAfter(t time.Duration, errorMsg string, fn func() error) error

TimeoutAfter executes the provide function and return the TimeoutError in case when the execution time of the provided function is bigger than provided time duration.

Types

type CallbackInvoker

type CallbackInvoker interface {
	ExecuteCallback(callbackURL string, success bool, labels map[string]string, messages []string) []string
}

CallbackInvoker posts results to a callback URL when a STI build is done.

func NewCallbackInvoker

func NewCallbackInvoker() CallbackInvoker

NewCallbackInvoker creates an instance of the default CallbackInvoker implementation

type CommandOpts

type CommandOpts struct {
	Stdout io.Writer
	Stderr io.Writer
	Dir    string
}

CommandOpts contains options to attach Stdout/err to a command to run or set its initial directory

type CommandRunner

type CommandRunner interface {
	RunWithOptions(opts CommandOpts, name string, arg ...string) error
	Run(name string, arg ...string) error
}

CommandRunner executes OS commands with the given parameters and options

func NewCommandRunner

func NewCommandRunner() CommandRunner

NewCommandRunner creates a new instance of the default implementation of CommandRunner

type FileSystem

type FileSystem interface {
	Chmod(file string, mode os.FileMode) error
	Rename(from, to string) error
	MkdirAll(dirname string) error
	Mkdir(dirname string) error
	Exists(file string) bool
	Copy(sourcePath, targetPath string) error
	CopyContents(sourcePath, targetPath string) error
	RemoveDirectory(dir string) error
	CreateWorkingDirectory() (string, error)
	Open(file string) (io.ReadCloser, error)
	WriteFile(file string, data []byte) error
	ReadDir(string) ([]os.FileInfo, error)
	Stat(string) (os.FileInfo, error)
}

FileSystem allows STI to work with the file system and perform tasks such as creating and deleting directories

func NewFileSystem

func NewFileSystem() FileSystem

NewFileSystem creates a new instance of the default FileSystem implementation

type TimeoutError

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

TimeoutError is error returned after timeout occured.

func (*TimeoutError) Error

func (t *TimeoutError) Error() string

Error implements the Go error interface.
