Types

type Flag

type Flag uint8

Flag is a type used to represent layer metadata flags.

const (
	// Build indicates that a layer should be used for builds
	Build Flag = iota

	// Cache indicates that a layer should be cached
	Cache

	// Launch indicates that a layer should be used for launch
	Launch
)

type Layer

type Layer struct {
	// Root is the path to the root directory for the layer.
	Root string

	// Metadata is the location of the layer's metadata file.
	Metadata string
	// contains filtered or unexported fields
}

Layer represents a layer for an application.

func (Layer) AppendBuildEnv

func (l Layer) AppendBuildEnv(name string, format string, args ...interface{}) error

AppendBuildEnv appends the value of this environment variable to any previous declarations of the value without any delimitation. If delimitation is important during concatenation, callers are required to add it.

func (Layer) AppendLaunchEnv

func (l Layer) AppendLaunchEnv(name string, format string, args ...interface{}) error

AppendLaunchEnv appends the value of this environment variable to any previous declarations of the value without any delimitation. If delimitation is important during concatenation, callers are required to add it.

func (Layer) AppendPathSharedEnv

func (l Layer) AppendPathSharedEnv(name string, format string, args ...interface{}) error

AppendPathSharedEnv appends the value of this environment variable to any previous declarations of the value using the OS path delimiter.

Deprecated: Use PrependPathSharedEnv

func (Layer) AppendSharedEnv

func (l Layer) AppendSharedEnv(name string, format string, args ...interface{}) error

AppendSharedEnv appends the value of this environment variable to any previous declarations of the value without any delimitation. If delimitation is important during concatenation, callers are required to add it.

func (Layer) PrependBuildEnv

func (l Layer) PrependBuildEnv(name string, format string, args ...interface{}) error

PrependBuildEnv prepends the value of this environment variable to any previous declarations of the value without any delimitation. If delimitation is important during concatenation, callers are required to add it.

func (Layer) PrependLaunchEnv

func (l Layer) PrependLaunchEnv(name string, format string, args ...interface{}) error

PrependLaunchEnv prepends the value of this environment variable to any previous declarations of the value without any delimitation. If delimitation is important during concatenation, callers are required to add it.

func (Layer) PrependPathBuildEnv
