mapPool

Arguments

:: Traversable t

=> Int

Number of pooled worker threads

-> ((String -> IO ()) -> a -> Hocker FilePath)

Processing function

-> t a

A Traversable container

-> Hocker (t (Either HockerException FilePath))

Like mapM but concurrently apply a function to the elements of the Traversable, limiting the maximum number of worker threads by _n_.

forPool

Arguments

:: Traversable t

=> Int

Number of pooled worker threads

-> t a

A Traversable container

-> ((String -> IO ()) -> a -> Hocker FilePath)

Processing function

-> Hocker (t (Either HockerException FilePath))

Like mapPool but with the arguments flipped.

fetchLayer

Arguments

:: (String -> IO ())

Concurrent terminal output function

-> (RefLayer, Layer)

A tuple of the reference layer hash digest from the image's config JSON and hash digest from the image's manifest JSON

-> Hocker FilePath

Download, verify, decompress, and write a docker container image layer to the filesystem.

createImageManifest

Arguments

:: RepoTag

e.g: registry.mydomain.net:5001reponameimagename

-> FilePath

Path of image config file for manifest

-> [RefLayer]

Layer hash digests sourced from the image's config JSON

-> Hocker ()

Generate a manifest.json file.

createImageRepository

Arguments

:: RepoTag

e.g: registry.mydomain.net:5001reponameimagename

-> [RefLayer]

Layer hash digests sourced from the image's configuration JSON

-> Hocker ()

Generate a repositories json file.

NB: it is JSON but Docker doesn't want it a .json extension unlike its sibling the manifest.json file.

createImageTar :: Hocker FilePath

Tar and gzip the output dir into the final docker image archive and remove the output dir.
