CopyThing copies either a dir or file to the target.

func DirCopy

func DirCopy(dest string, source string) error

DirCopy copies a whole directory recursively

func FileCopy

Types

type GenerateBOMOpts

type GenerateBOMOpts struct {
	Path string
	Dest string
}

type Graph

type Graph interface {
	// AddVertex creates a new vertex in the graph with the specified key and stores
	// value provided in the vertex. It returns an error if the vertex specified by
	// the key already exists.
	AddVertex(Key, Value) error

	// RemoveVertex removes the vertex specified by the key. It returns an error
	// if the vertex corresponding to the key is not present in the graph.
	RemoveVertex(Key) error

	// AddDependencies creates a dependency between a given vertex and the provided
	// list of dependency vertices. This returns an error if either the vertex or the
	// dependency is not present in the graph or a make a node depends on itself.
	// Adding an dependency that creates a cycle in the graph is not allowed.
	AddDependencies(Key, ...Key) error

	// GetValue returns the value of the vertex specified by the key. It returns nil if the
	// vertex is not present in the graph.
	GetValue(Key) Value

	// SetValue sets the value of the vertex specified by the key. It returns an error if
	// the vertex is not present in the graph
	SetValue(Key, Value) error

	// Sort returns all the vertex entries in the dependency order. Vertices are ordered in
	// such a way that a vertex's dependencies will always preseed itself.
	Sort() []Vertex
}

Graph is collection of vertices and edges between them. In dag, sort implement a topological sort for the graph.

func NewDAG

func NewDAG() Graph

NewDAG creates a new DAG.

type ImageCopyOpts

type ImageCopyOpts struct {
	Src               string
	SrcUsername       string
	SrcPassword       string
	Dest              string
	DestUsername      string
	DestPassword      string
	ForceManifestType string
	SrcSkipTLS        bool
	DestSkipTLS       bool
	Progress          io.Writer
	Context           context.Context
}

type Key

type Key interface{}

Key for a component

type Value

type Value interface{}

Value is the actual component object

type Vertex

type Vertex struct {
	Key   Key
	Value Value
}

Vertex in the graph has the entry of <key, value> for a component
