Types

type BindMountSourceCreator

type BindMountSourceCreator interface {
	Create(containerDir string, privileged bool) ([]garden.BindMount, error)
}

type BundleGenerator

type BundleGenerator interface {
	Generate(desiredContainerSpec spec.DesiredContainerSpec, containerDir string) (goci.Bndl, error)
}

type BundleLoader

type BundleLoader interface {
	Load(bundleDir string) (goci.Bndl, error)
}

type BundleSaver

type BundleSaver interface {
	Save(bundle goci.Bndl, path string) error
}

type Chowner

type Chowner interface {
	Chown(path string, uid, gid int) error
}

type DepotBindMountSourceCreator

type DepotBindMountSourceCreator struct {
	BindMountPoints      []string
	Chowner              Chowner
	ContainerRootHostUID int
	ContainerRootHostGID int
}

func (DepotBindMountSourceCreator) Create

func (b DepotBindMountSourceCreator) Create(containerDir string, chown bool) ([]garden.BindMount, error)

Create will create and chown a file in the container's depot to be bind-mounted into the container. The name of this file will be the basename of the mount destination. A consequence of this is that we currently can't create mountpoints with the same basename, e.g. /var/foo and /etc/foo. This restriction doesn't affect user-provided bind mounts.

type DirectoryDepot

type DirectoryDepot struct {
	BindMountSourceCreator BindMountSourceCreator
	// contains filtered or unexported fields
}

a depot which stores containers as subdirs of a depot directory

func New

func New(dir string, bundler BundleGenerator, bundleSaver BundleSaver, bindMountSourceCreator BindMountSourceCreator) *DirectoryDepot

func (*DirectoryDepot) Create

func (d *DirectoryDepot) Create(log lager.Logger, handle string, spec spec.DesiredContainerSpec) error

func (*DirectoryDepot) Destroy

func (d *DirectoryDepot) Destroy(log lager.Logger, handle string) error

func (*DirectoryDepot) GetDir

func (d *DirectoryDepot) GetDir() string

func (*DirectoryDepot) Handles

func (d *DirectoryDepot) Handles() ([]string, error)

func (*DirectoryDepot) Lookup

func (d *DirectoryDepot) Lookup(log lager.Logger, handle string) (string, error)

type OSChowner

type OSChowner struct{}

func (*OSChowner) Chown

func (*OSChowner) Chown(path string, uid, gid int) error
