runway.module.base module

Base classes for runway modules.

class runway.module.base.RunwayModule[source]

Bases: object

Base class for Runway modules.

__init__(context: RunwayContext, *, explicitly_enabled: Optional[bool] = False, logger: RunwayLogger = <RunwayLogger runway.module.base (WARNING)>, module_root: Path, name: Optional[str] = None, options: Optional[Union[Dict[str, Any], ModuleOptions]] = None, parameters: Optional[Dict[str, Any]] = None, **_: Any) → None[source]

Instantiate class.

Parameters

  • context – Runway context object for the current session.

  • explicitly_enabled – Whether or not the module is explicitly enabled. This is can be set in the event that the current environment being deployed to matches the defined environments of the module/deployment.

  • logger – Used to write logs.

  • module_root – Root path of the module.

  • name – Name of the module.

  • options – Options passed to the module class from the config as options or module_options if coming from the deployment level.

  • parameters – Values to pass to the underlying infrastructure as code tool that will alter the resulting infrastructure being deployed. Used to templatize IaC.

deploy() → None[source]

Abstract method called when running deploy.

destroy() → None[source]

Abstract method called when running destroy.

init() → None[source]

Abstract method called when running init.

plan() → None[source]

Abstract method called when running plan.

__getitem__(key: str) → Any[source]

Make the object subscriptable.

Parameters

key – Attribute to get.

__new__(**kwargs)
class runway.module.base.RunwayModuleNpm[source]

Bases: runway.module.base.RunwayModule

Parameters

command – List that will be passed into a subprocess.

npm_install() → None[source]

Parameters

key – Attribute to get.

__new__(**kwargs)
deploy() → None

Abstract method called when running deploy.

destroy() → None

package_json_missing() → bool[source]
