type VFS

type VFS interface {
}

type VFSContext

type VFSContext struct {

func (*VFSContext) ReadFile

func (c *VFSContext) ReadFile(location string) ([]byte, error)

ReadLocation reads a file from a vfs URL It supports additional schemes which don't (yet) have full VFS implementations:

metadata: reads from instance metadata on GCE/AWS
http / https: reads from HTTP
