otopi -- oVirt Task Oriented Pluggable Installer/Implementation

Copr build status

Standalone plugin based installation framework to be used to setup system components. The plugin nature provides simplicity to add new installation functionality without the complexity of the state and transaction management.

At the core of the implementation there is environment dictionary and a flow of stages within plugins. The environment can be modified using command-line parameters, configuration file, or dialog customization.

Features:

  • otopi is a library for component installation.

  • Modular, task oriented implementation.

  • Supports pluggable manager dialog protocol, provides human and machine dialogs.

  • Localization support, gettext enabled.

  • Local and remote execution modes are supported.

  • Distribution independent implementation (core).

  • Compatible with python-3.6, 3.9

USAGE

otopi [variables]

variables ::= name=type:value variables | APPEND:name=type:value | ''
type ::= none | bool | int | str | multi-str

APPEND: prefix appends as colon list string.

CUSTOMIZATION

    [environment:override]
    key=type:value

    [environment:enforce]
    key=type:value
