B9.Container

Description

An interface for container backends such as libvirt-lxc or docker

Synopsis

class Backend config where
- getBackendConfig :: forall proxy e. (Member BuildInfoReader e, CommandIO e) => proxy config -> Eff e (Maybe config)
- supportedImageTypes :: proxy config -> [ImageType]
- runInEnvironment :: forall e. (Member BuildInfoReader e, CommandIO e, Member ExcB9 e) => config -> ExecEnv -> Script -> Eff e Bool

Documentation

class Backend config where Source #

Class of backends that run a Script in an ExecEnv in an OS-level container like docker or lxc.

Minimal complete definition

getBackendConfig, runInEnvironment

Methods

getBackendConfig :: forall proxy e. (Member BuildInfoReader e, CommandIO e) => proxy config -> Eff e (Maybe config) Source #

Return Nothing if the configuration **disables** this container backend, and return 'Just ...' if the configuration **enables** this container backend.

supportedImageTypes :: proxy config -> [ImageType] Source #

The input images, that a given container accepts

runInEnvironment :: forall e. (Member BuildInfoReader e, CommandIO e, Member ExcB9 e) => config -> ExecEnv -> Script -> Eff e Bool Source #

Run a Script in an ExecEnv, and return True if the script completed successfully.
