package registry
// Registry abstracts a types registry which holds types that can be
// used in a Deployment Manager configurations. A registry root must have
// a 'types' directory which contains all the available types. Each type
// then contains version directories which in turn contains all the files
// necessary for that version of the type.
// For example a type registry holding two types:
// redis v1 (implemented in jinja)
// replicatedservice v2 (implemented in python)
// would have a directory structure like so:
// /types/redis/v1
// redis.jinja
// redis.jinja.schema
// /types/replicatedservice/v2
// replicatedservice.python
// replicatedservice.python.schema
const TypesDir string = "types"
type Type struct {
Name string
Version string
}
// Registry abstracts type interactions.
type Registry interface {
// List all the types in the given registry
List() ([]Type, error)
// Get the download URL for a given type and version
GetURL(t Type) (string, error)
