func Detect ¶

func Detect(config backend.BuildConfig) (remote builder.Source, dockerfile *parser.Result, err error)

Detect returns a context and dockerfile from remote location or local archive.

func FromArchive ¶

func FromArchive(tarStream io.Reader) (builder.Source, error)

FromArchive returns a build source from a tar stream.

It extracts the tar stream to a temporary folder that is deleted as soon as the Context is closed. As the extraction happens, a tarsum is calculated for every file, and the set of all those sums then becomes the source of truth for all operations on this Context.

Closing tarStream has to be done by the caller.

func FullPath ¶

func FullPath(remote builder.Source, path string) (string, error)

FullPath is a helper for getting a full path for a path from a source

func GetWithStatusError ¶

func GetWithStatusError(address string) (resp *http.Response, err error)

GetWithStatusError does an http.Get() and returns an error if the status code is 4xx or 5xx.

func MakeGitContext ¶

func MakeGitContext(gitURL string) (builder.Source, error)

MakeGitContext returns a Context from gitURL that is cloned in a temporary directory.

func NewFileHash ¶

func NewFileHash(path, name string, fi os.FileInfo) (hash.Hash, error)

NewFileHash returns new hash that is used for the builder cache keys

func NewLazySource ¶

func NewLazySource(root string) (builder.Source, error)

NewLazySource creates a new LazyContext. LazyContext defines a hashed build context based on a root directory. Individual files are hashed first time they are asked. It is not safe to call methods of LazyContext concurrently.

func Rel ¶

func Rel(basepath string, targpath string) (string, error)

Rel makes a path relative to base path. Same as `filepath.Rel` but can also handle UUID paths in windows.

func StatAt ¶

func StatAt(remote builder.Source, path string) (os.FileInfo, error)

StatAt is a helper for calling Stat on a path from a source
