LocalFile Image ImageResize | Write an image file to the path in the first argument., possible resizing it, |

EmptyImage String FileSystem ImageType ImageSize | Create an empty image file having a file system label
(first parameter), a file system type (e.g. |

Instances
A data type for image file or file system size; instead of passing Int
s
around this also captures a size unit so that the Int
can be kept small
Instances
sizeUnitKiB :: SizeUnit -> Int Source #
Convert a SizeUnit
to the number of kibi bytes one element represents.
normalizeSize :: ImageSize -> ImageSize Source #
Choose the greatest unit possible to exactly represent an ImageSize
.
Enumeration of size multipliers. The exact semantics may vary depending on
what external tools look at these. E.g. the size unit is convert to a size
parameter of the qemu-img
command line tool.

a file system contained in the image file might be
corrupted by this operation. To not only resize the image
file but also the fil system contained in it, use

type Mounted a = (a, MountPoint) Source #
A type alias that indicates that something of type a

MountPoint
Shared Images
data SharedImage Source #
SharedImage
holds all data necessary to describe an instance of a shared
image identified by a SharedImageName
. Shared images are stored in
Repository
s.
newtype SharedImageName Source #
The name of the image is the de-facto identifier for push, pull, From
and
Share
. B9 always selects the newest version the shared image identified
by that name when using a shared image as an ImageSource
. This is a
wrapper around a string that identifies a SharedImage
fromSharedImageName :: SharedImageName -> String Source #
Get the String representation of a SharedImageName
.
newtype SharedImageDate Source #
The exact time that build job started.
This is a wrapper around a string contains the build date of a
SharedImage
; this is purely additional convenience and typesafety
newtype SharedImageBuildId Source #
Every B9 build running in a B9Monad
contains a random unique id that is generated once per build (no matter how
many artifacts are created in that build) This field contains the build id
of the build that created the shared image instance. This is A wrapper
around a string contains the build id of a SharedImage
; this is purely
additional convenience and typesafety
fromSharedImageBuildId :: SharedImageBuildId -> String Source #
Get the String representation of a SharedImageBuildId
.
sharedImagesToMap :: [SharedImage] -> Map SharedImageName (Set SharedImage) Source #
Transform a list of SharedImage
values into a Map
that associates
each SharedImageName
with a Set
of the actual images with that name.
The Set
contains values of type
.SharedImage
The Ord
instance of SharedImage
sorts by name first and then by
sharedImageDate
, since the values in a Set
share the same sharedImageName
,
they are effectively orderd by build date, which is useful the shared image cleanup.
Since: 1.1.0
takeLatestSharedImage :: [SharedImage] -> Maybe SharedImage Source #
Return the SharedImage
with the highest sharedImageDate
.
