Functions ¶

func InitializeImageCache ¶

func InitializeImageCache(client *client.PortLayer) error

InitializeImageCache will create a new image cache or rehydrate an existing image cache from the portlayer k/v store

func NewRepositoryCache ¶

func NewRepositoryCache(client *client.PortLayer) error

NewRespositoryCache will create a new repoCache or rehydrate an existing repoCache from the portlayer k/v store

Types ¶

type Association ¶

type Association struct {
	Ref     reference.Named
	ImageID string
}

An Association is a tuple associating a reference with an image ID.

type CCache ¶

type CCache struct {
	// contains filtered or unexported fields
}

Tracks our container info from calls

func ContainerCache ¶

func ContainerCache() *CCache

ContainerCache returns a reference to the container cache

func (*CCache) AddContainer ¶

func (cc *CCache) AddContainer(container *container.VicContainer)

func (*CCache) AddExecToContainer ¶

func (cc *CCache) AddExecToContainer(container *container.VicContainer, eid string)

func (*CCache) DeleteContainer ¶

func (cc *CCache) DeleteContainer(nameOrID string)

func (*CCache) GetContainer ¶

func (cc *CCache) GetContainer(nameOrID string) *container.VicContainer

func (*CCache) GetContainerByName ¶

func (cc *CCache) GetContainerByName(nameOnly string) *container.VicContainer

GetContainerByName returns a container whose name "exactly" matches nameOnly

func (*CCache) GetContainerFromExec ¶

func (cc *CCache) GetContainerFromExec(eid string) *container.VicContainer

func (*CCache) ReleaseName ¶

func (cc *CCache) ReleaseName(name string)

ReleaseName is used during a container rename operation to allow concurrent container create/rename operations to use the name. It is also used during a failed create operation to allow subsequent create operations to use that name.

func (*CCache) ReserveName ¶

func (cc *CCache) ReserveName(container *container.VicContainer, name string) error

ReserveName is used during a container create/rename operation to prevent concurrent container create/rename operations from grabbing the new name.

func (*CCache) UpdateContainerName ¶

func (cc *CCache) UpdateContainerName(oldName, newName string) error

UpdateContainerName assumes that the newName is already reserved by ReserveName so no need to check the existence of a container with the new name.

type ICache ¶

type ICache struct {
	// contains filtered or unexported fields
}

ICache is an in-memory cache of image metadata. It is refreshed at startup by a call to the portlayer. It is updated when new images are pulled or images are deleted.

func ImageCache ¶

func ImageCache() *ICache

ImageCache returns a reference to the image cache

func (*ICache) Add ¶

func (ic *ICache) Add(imageConfig *metadata.ImageConfig) error

Add adds an image to the image cache

func (*ICache) Get ¶

func (ic *ICache) Get(idOrRef string) (*metadata.ImageConfig, error)

Get parses input to retrieve a cached image

func (*ICache) GetImages ¶

func (ic *ICache) GetImages() []*metadata.ImageConfig

GetImages returns a slice containing metadata for all cached images

func (*ICache) IsImageID ¶

func (ic *ICache) IsImageID(id string) bool

IsImageID will check that a full or partial imageID exists in the cache

func (*ICache) RemoveImageByConfig ¶

func (ic *ICache) RemoveImageByConfig(imageConfig *metadata.ImageConfig)

RemoveImageByConfig removes image from the cache.

func (*ICache) Save ¶

func (ic *ICache) Save() error

Save will persist the image cache to the portlayer k/v store

type Repo ¶

type Repo interface {
	References(imageID string) []reference.Named
	ReferencesByName(ref reference.Named) []Association
	Delete(ref reference.Named, save bool) (bool, error)
	Get(ref reference.Named) (string, error)

	Save() error
	GetImageID(layerID string) string
	Tags(imageID string) []string
	Digests(imageID string) []string
	AddReference(ref reference.Named, imageID string, force bool, layerID string, save bool) error

	// Remove will remove from the cache and returns the
	// stringified Named if successful -- save bool instructs
	// func to persist to portlayer k/v or not
	Remove(ref string, save bool) (string, error)
}

Repo provides the set of methods which can operate on a tag store.

func RepositoryCache ¶

func RepositoryCache() Repo

RepositoryCache returns a ref to the repoCache interface
