Hocker.Types

Documentation

type RegistryURI = URIRef Absolute

Docker registry URI.

type Username = Text

Docker registry username.

type Password = Text

Docker registry user password.

type Layer = Text

Docker image layer sha256 hash digest.

type StrippedDigest = Text

SHA256 hash digest with the hash algorithm identifier prefix, stripped

type Manifest = ByteString

Docker image manifest JSON.

type ImageConfigJSON = ByteString

Docker image config JSON.

type RspBS = Response ByteString

Wreq response type parameterized by the lazy bytestring type.

type Extension = String

A file extension.

type RepoNamePart = Text

RepoName is the part before the forward slash in a docker image name, e.g: library in library/debian

type ImageNamePart = Text

ImageName is the part after the forward slash in a docker image name, e.g: library in library/debian

type ConfigDigest = Base32Digest

Docker image config JSON file's sha256 hash digest in Nix's base32 encoding.

NB: it's very important to realize there's a significant difference between Nix's base32 encoding and the standard base32 encoding! (i.e, they're not compatible).

data Options w

Generic top-level optparse-generic CLI args data type and specification.

NOTE: `hocker-layer` does not use this data type because it requires an additional layer sha256 hash digest argument.

Constructors

Options

Fields

• registry :: w ::: (Maybe RegistryURI <?> "URI of registry, defaults to the Docker Hub registry")

  URI for the registry, optional

• credentials :: Maybe Credentials
• out :: w ::: (Maybe FilePath <?> "Write content to location")

  Filesystem path to write output to

• imageName :: ImageName

  Docker image name (includes the reponame, e.g: library/debian)

• imageTag :: ImageTag

  Docker image tag
