Functions

func FilterOldUnusedImages

func FilterOldUnusedImages(keepMax int, repoImages []*ecr.ImageDetail, tagsInUse []string) []*ecr.ImageDetail

FilterOldUnusedImages goes through the given list of ECR images and returns another list of images (giving priority to older images) that are not in use. This list will contain at most 100 images, which is the maximum number of images we are allowed to delete in a single API call to AWS.

func SortImagesByPushDate

func SortImagesByPushDate(images []*ecr.ImageDetail)

SortImagesByPushDate uses the `ImagesByPushDate` type to sort the given slice of ECR image objects.

Types

type ECRClient

type ECRClient interface {
	ListRepositories(repositoryNames []*string, registryID *string) ([]*ecr.Repository, error)
	ListImages(repositoryName *string, registryID *string) ([]*ecr.ImageDetail, error)
	BatchRemoveImages(images []*ecr.ImageDetail) error
}

ECRClient defines the expected interface of any object capable of listing and removing images from a ECR repository.

type ECRClientImpl

type ECRClientImpl struct {
	ECRClient ecriface.ECRAPI
}

ECRClientImpl provides an interface for mocking.

func NewECRClient

func NewECRClient(region string) *ECRClientImpl

NewECRClient returns a new client for interacting with the ECR API. The credentials are retrieved from environment variables or from the `~/.aws/credentials` file.

func (*ECRClientImpl) BatchRemoveImages

func (c *ECRClientImpl) BatchRemoveImages(images []*ecr.ImageDetail) error

BatchRemoveImages deletes all the given images in one go. All images must be stored in the same repository for this to work.

func (*ECRClientImpl) ListImages

func (c *ECRClientImpl) ListImages(repositoryName *string, registryID *string) ([]*ecr.ImageDetail, error)

ListImages returns data from all images stored in the repository identified by the given repository name.

func (*ECRClientImpl) ListRepositories

func (c *ECRClientImpl) ListRepositories(repositoryNames []*string, registryID *string) ([]*ecr.Repository, error)

ListRepositories returns the data belonging to the given repository names.

type ImagesByPushDate

type ImagesByPushDate []*ecr.ImageDetail

ImagesByPushDate lets us sort ECR images by push date so that we can delete old images.

func (ImagesByPushDate) Len

func (slice ImagesByPushDate) Len() int

func (ImagesByPushDate) Less

func (slice ImagesByPushDate) Less(i, j int) bool

func (ImagesByPushDate) Swap

func (slice ImagesByPushDate) Swap(i, j int)
