}

Deletor is the interface that wraps the Delete method.

Delete deletes the release named by key or returns ErrReleaseNotFound if the release does not exist.

type Driver

type Driver interface {
	Creator
	Updator
	Deletor
	Queryor
	Name() string
}

Driver is the interface composed of Creator, Updator, Deletor, and Queryor interfaces. It defines the behavior for storing, updating, deleted, and retrieving Tiller releases from some underlying storage mechanism, e.g. memory, configmaps.

func (mem *Memory) Create(key string, rls *rspb.Release) error

Create creates a new release or returns ErrReleaseExists.

func (*Memory) Delete

func (mem *Memory) Delete(key string) (*rspb.Release, error)

Delete deletes a release or returns ErrReleaseNotFound.

func (*Memory) Get

func (mem *Memory) Get(key string) (*rspb.Release, error)

Get returns the release named by key or returns ErrReleaseNotFound.

func (*Memory) List

func (mem *Memory) List(filter func(*rspb.Release) bool) ([]*rspb.Release, error)

List returns the list of all releases such that filter(release) == true

func (*Memory) Name

func (mem *Memory) Name() string

Name returns the name of the driver.

func (*Memory) Query

func (mem *Memory) Query(keyvals map[string]string) ([]*rspb.Release, error)

Query returns the set of releases that match the provided set of labels

func (*Memory) Update

func (mem *Memory) Update(key string, rls *rspb.Release) error

Update updates a release or returns ErrReleaseNotFound.

type Queryor

type Queryor interface {
	Get(key string) (*rspb.Release, error)
	List(filter func(*rspb.Release) bool) ([]*rspb.Release, error)
	Query(labels map[string]string) ([]*rspb.Release, error)
}

Queryor is the interface that wraps the Get and List methods.

Get returns the release named by key or returns ErrReleaseNotFound if the release does not exist.

List returns the set of all releases that satisfy the filter predicate.

Query returns the set of all releases that match the provided label set.

type SQL

type SQL struct {
	Log func(string, ...interface{})
	// contains filtered or unexported fields
}

SQL is the sql storage driver implementation.

func NewSQL

func NewSQL(dialect, connectionString string, logger func(string, ...interface{})) (*SQL, error)

NewSQL initializes a new memory driver.

func (*SQL) Create

func (s *SQL) Create(key string, rls *rspb.Release) error

	// The rspb.Release body, as a base64-encoded string
	Body string `db:"body"`

	// Release "labels" that can be used as filters in the storage.Query(labels map[string]string)
	// we implemented. Note that allowing Helm users to filter against new dimensions will require a
	// new migration to be added, and the Create and/or update functions to be updated accordingly.
	Name       string `db:"name"`
	Version    int    `db:"version"`
	Status     string `db:"status"`
