Docker Storage Driver Benchmarks and Tests 
dsdbench runs benchmarks and tests for storage driver configurations to help
figure out how the configuration will perform and which known issues the
daemon may be affected by in this configuration.
Usage
dsdbench makes use of the golang testing package. The tests may need to be
run as root in order to successfully mount. Use DOCKER_GRAPHDRIVER and
DOCKER_GRAPHDRIVER_OPTIONS environment variables to configure.
Run tests
$ DOCKER_GRAPHDRIVER=overlay2 go test -v .
Run benchmarks
$ DOCKER_GRAPHDRIVER=overlay2 go test -run=NONE -v -bench .

Functions ¶
func CheckDirectoryEqual ¶
CheckDirectoryEqual compares two directory paths to make sure that the content of the directories is the same.
func CheckLayer ¶
CheckLayer checks that the provider layer directory content exactly matches a directory created using the provided layer initializers.
func CheckLayerDiff ¶
CheckLayerDiff checks that the diff stream for the provided layer exactly matches the provided byte array.
func CheckMetadata ¶
CheckMetadata checks that 2 metadata arrays are equal
func CheckSameLayer ¶
CheckSameLayer checks whether the 2 provides layers are same. The layers must have the exact same digests, size, and parents.
func CreateLayer ¶
func CreateLayer(ls layer.Store, parent layer.ChainID, layerFunc LayerInit) (l layer.Layer, err error)
CreateLayer creates a new layer in the layer store using the given layer initialize function on top of the given parent.
func CreateLayerChain ¶
CreateLayerChain creates a new chain of layers in the given layer store using the provided layer initializers and returns the topmost layer.
func CreateMetadata ¶
CreateMetadata creates a metadata array from the provided layers in a manner that would be returned from the layer store on removal.
func TarFromFiles ¶
TarFromFiles returns an uncompressed tar byte array created from using the provided file appliers.
Types ¶
type ApplyFile ¶
ApplyFile applies single file changes
func CreateDirectory ¶
CreateDirectory returns a file applier to create the directory with the provided name and permission
func NewTestFile ¶
NewTestFile returns a file applier which creates a file as the provided name with the given content and permission.
func RemoveFile ¶
RemoveFile returns a file applier which removes the provided file name
