Types

type Storage

type Storage struct {
	driver.Driver
}

Storage represents a storage engine for a Release.

func Init

func Init(d driver.Driver) *Storage

Init initializes a new storage backend with the driver d. If d is nil, the default in-memory driver is used.

func (*Storage) Create

func (s *Storage) Create(rls *rspb.Release) error

Create creates a new storage entry holding the release. An error is returned if the storage driver failed to store the release, or a release with identical an key already exists.

func (*Storage) Delete

func (s *Storage) Delete(name string, version int32) (*rspb.Release, error)

Delete deletes the release from storage. An error is returned if the storage backend fails to delete the release or if the release does not exist.

func (*Storage) Deployed

func (s *Storage) Deployed(name string) (*rspb.Release, error)

Deployed returns the deployed release with the provided release name, or returns ErrReleaseNotFound if not found.

func (*Storage) Get

func (s *Storage) Get(name string, version int32) (*rspb.Release, error)

Get retrieves the release from storage. An error is returned if the storage driver failed to fetch the release, or the release identified by the key, version pair does not exist.

func (*Storage) History

func (s *Storage) History(name string) ([]*rspb.Release, error)

History returns the revision history for the release with the provided name, or returns ErrReleaseNotFound if no such release name exists.

func (*Storage) Last

func (s *Storage) Last(name string) (*rspb.Release, error)

func (*Storage) ListDeleted

func (s *Storage) ListDeleted() ([]*rspb.Release, error)

ListDeleted returns all releases with Status == DELETED. An error is returned if the storage backend fails to retrieve the releases.

func (*Storage) ListDeployed

func (s *Storage) ListDeployed() ([]*rspb.Release, error)

ListDeployed returns all releases with Status == DEPLOYED. An error is returned if the storage backend fails to retrieve the releases.

func (*Storage) ListFilterAll

func (s *Storage) ListFilterAll(fns ...relutil.FilterFunc) ([]*rspb.Release, error)

ListFilterAll returns the set of releases satisfying satisfying the predicate (filter0 && filter1 && ... && filterN), i.e. a Release is included in the results if and only if all filters return true.

func (*Storage) ListFilterAny

func (s *Storage) ListFilterAny(fns ...relutil.FilterFunc) ([]*rspb.Release, error)

ListFilterAny returns the set of releases satisfying satisfying the predicate (filter0 || filter1 || ... || filterN), i.e. a Release is included in the results if at least one of the filters returns true.

func (*Storage) ListReleases

func (s *Storage) ListReleases() ([]*rspb.Release, error)

ListReleases returns all releases from storage. An error is returned if the storage backend fails to retrieve the releases.

func (*Storage) Update

func (s *Storage) Update(rls *rspb.Release) error

Update update the release in storage. An error is returned if the storage backend fails to update the release or if the release does not exist.
