Functions

func FindSource

func FindSource() (root string, err error)

FindSource attempts to locate a kubernetes checkout using go's build package

Types

type Bits

type Bits interface {
	// BinaryPaths returns a list of paths to binaries on the host machine that
	// should be added to PATH in the Node image
	BinaryPaths() []string
	// ImagePaths returns a list of paths to image archives to be loaded into
	// the Node
	ImagePaths() []string
	// Version
	Version() string
}

Bits provides the locations of Kubernetes Binaries / Images needed on the cluster nodes Implementations should be registered with RegisterNamedBits

type Builder

type Builder interface {
	// Build returns a Bits and any errors encountered while building Kubernetes.
	// Some implementations (upstream binaries) may use this step to obtain
	// an existing build instead
	Build() (Bits, error)
}

Builder represents and implementation of building Kubernetes building may constitute downloading a release

func NewDockerBuilder

func NewDockerBuilder(logger log.Logger, kubeRoot, arch string) (Builder, error)

NewDockerBuilder returns a new Bits backed by the docker-ized build, given kubeRoot, the path to the kubernetes source directory

func NewReleaseBuilder

func NewReleaseBuilder(logger log.Logger, version, arch string) (Builder, error)

NewReleaseBuilder used to specify a release semver and constructs a url to release artifacts

func NewTarballBuilder

func NewTarballBuilder(logger log.Logger, tarballPath string) (Builder, error)

NewTarballBuilder returns a new Bits backed by the docker-ized build, given kubeRoot, the path to the kubernetes source directory

func NewURLBuilder

func NewURLBuilder(logger log.Logger, url string) (Builder, error)

NewURLBuilder used to specify a complete url to a gzipped tarball
