Types ¶
type Handler ¶
type Handler interface {
Handle(ctx context.Context, ImageUploaded *ImageUploaded) error
}
Handler represents a handler for processing a single event.
type ImageAPIClient ¶
type ImageAPIClient interface {
Checker(ctx context.Context, state *healthcheck.CheckState) error
GetImage(ctx context.Context, userAuthToken, serviceAuthToken, collectionID, imageID string) (image.Image, error)
PutImage(ctx context.Context, userAuthToken, serviceAuthToken, collectionID, imageID string, data image.Image) (image.Image, error)
PostDownloadVariant(ctx context.Context, userAuthToken, serviceAuthToken, collectionID, imageID string, data image.NewImageDownload) (image.ImageDownload, error)
PutDownloadVariant(ctx context.Context, userAuthToken, serviceAuthToken, collectionID, imageID, variant string, data image.ImageDownload) (image.ImageDownload, error)
}
ImageAPIClient defines the required methods from image API client
type ImageUploaded ¶
type ImageUploaded struct {
Path string `avro:"path"`
ImageID string `avro:"image_id"`
Filename string `avro:"filename"`
}
ImageUploaded provides an avro structure for an image uploaded event
type ImageUploadedHandler ¶
type ImageUploadedHandler struct {
AuthToken string
S3Upload S3Reader
S3Private S3Writer
VaultCli VaultClient
VaultPath string
ImageCli ImageAPIClient
DownloadServiceURL string
}
ImageUploadedHandler ...
func (*ImageUploadedHandler) Handle ¶
func (h *ImageUploadedHandler) Handle(ctx context.Context, event *ImageUploaded) (err error)
Handle takes a single event. It reads the PSK from Vault, uses it to decrypt the encrypted file from the uploaded S3 bucket, and writes it to the private bucket with a new vault psk for encryption. It also calls the API to create a new download variant and to update it after the variant has been imported.
type S3Reader ¶
type S3Reader interface {
Checker(ctx context.Context, state *healthcheck.CheckState) error
Session() *session.Session
BucketName() string
Get(key string) (io.ReadCloser, *int64, error)
GetWithPSK(key string, psk []byte) (io.ReadCloser, *int64, error)
}
S3Reader defines the required methods from dp-s3 to read data to an AWS S3 Bucket
type S3Writer ¶
type S3Writer interface {
Checker(ctx context.Context, state *healthcheck.CheckState) error
Session() *session.Session
BucketName() string
Upload(input *s3manager.UploadInput, options ...func(*s3manager.Uploader)) (*s3manager.UploadOutput, error)
UploadWithPSK(input *s3manager.UploadInput, psk []byte) (*s3manager.UploadOutput, error)
}
S3Writer defines the required methods from dp-s3 to interact with a particular bucket of AWS S3
type VaultClient ¶
type VaultClient interface {
ReadKey(path, key string) (string, error)
WriteKey(path, key, value string) error
Checker(ctx context.Context, state *healthcheck.CheckState) error
}
VaultClient defines the required methods from dp-vault client
