Types ¶
type FileStorage ¶
type FileStorage interface {
Delete(ctx context.Context, objectId string) error
Exists(ctx context.Context, objectId string) (bool, error)
LastModified(ctx context.Context, objectId string) (time.Time, error)
PutRequest(ctx context.Context, objectId string,
duration time.Duration) (*images.Link, error)
GetRequest(ctx context.Context, objectId string,
duration time.Duration, responseContentType string) (*images.Link, error)
UploadArtifact(ctx context.Context, objectId string,
artifactSize int64, artifact io.Reader, contentType string) error
}
FileStorage allows to store and manage large files
type ImageUsedIn ¶
type ImageUsedIn interface {
ImageUsedInActiveDeployment(ctx context.Context, imageId string) (bool, error)
ImageUsedInDeployment(ctx context.Context, imageId string) (bool, error)
}
Allows to check of image is used in different deployment status groups
type ImagesModel ¶
type ImagesModel struct {
// contains filtered or unexported fields
}
func NewImagesModel ¶
func NewImagesModel( fileStorage FileStorage, checker ImageUsedIn, imagesStorage SoftwareImagesStorage, ) *ImagesModel
func (*ImagesModel) CreateImage ¶
func (i *ImagesModel) CreateImage(ctx context.Context, multipartUploadMsg *controller.MultipartUploadMsg) (string, error)
CreateImage parses artifact and uploads artifact file to the file storage - in parallel, and creates image structure in the system. Returns image ID and nil on success.
func (*ImagesModel) DeleteImage ¶
func (i *ImagesModel) DeleteImage(ctx context.Context, imageID string) error
DeleteImage removes metadata and image file Noop for not exisitng images Allowed to remove image only if image is not scheduled or in progress for an updates - then image file is needed In case of already finished updates only image file is not needed, metadata is attached directly to device deployment therefore we still have some information about image that have been used (but not the file)
func (*ImagesModel) DownloadLink ¶
func (i *ImagesModel) DownloadLink(ctx context.Context, imageID string, expire time.Duration) (*images.Link, error)
DownloadLink presigned GET link to download image file. Returns error if image have not been uploaded.
func (*ImagesModel) EditImage ¶
func (i *ImagesModel) EditImage(ctx context.Context, imageID string, constructor *images.SoftwareImageMetaConstructor) (bool, error)
EditObject allows editing only if image have not been used yet in any deployment.
func (*ImagesModel) GetImage ¶
func (i *ImagesModel) GetImage(ctx context.Context, id string) (*images.SoftwareImage, error)
GetImage allows to fetch image obeject with specified id Nil if not found
func (*ImagesModel) ListImages ¶
func (i *ImagesModel) ListImages(ctx context.Context, filters map[string]string) ([]*images.SoftwareImage, error)
ListImages according to specified filers.
type SoftwareImagesStorage ¶
type SoftwareImagesStorage interface {
Exists(ctx context.Context, id string) (bool, error)
Update(ctx context.Context, image *images.SoftwareImage) (bool, error)
Insert(ctx context.Context, image *images.SoftwareImage) error
FindByID(ctx context.Context, id string) (*images.SoftwareImage, error)
IsArtifactUnique(ctx context.Context, artifactName string,
deviceTypesCompatible []string) (bool, error)
Delete(ctx context.Context, id string) error
FindAll(ctx context.Context) ([]*images.SoftwareImage, error)
}
SoftwareImagesStorage allow to store and manage image.SoftwareImages
