runway.module.k8s module

K8s (kustomize) module.

class runway.module.k8s.K8s[source]

Bases: runway.module.base.RunwayModule

Kubectl Runway Module.

__init__(context: RunwayContext, *, explicitly_enabled: Optional[bool] = False, logger: RunwayLogger = <RunwayLogger runway.module.k8s (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.

property kbenv: runway.env_mgr.kbenv.KBEnvManager: Kubectl environment manager.

property kubectl_bin: str: Path to kubectl binary.

property skip: bool: Determine if the module should be skipped.

deploy() → None[source]: Run kubectl apply.

destroy() → None[source]: Run kubectl delete.

gen_cmd(command: typing_extensions.Literal[annotation, apply, auth, autoscale, cp, create, delete, describe, diff, edit, exec, expose, get, kustomize, label, logs, patch, port - forward, proxy], args_list: Optional[List[str]] = None) → List[str][source]

Generate and log a kubectl command.

This does not execute the command, only prepares it for use.

Parameters

command – The CDK command to be executed.
args_list – Additional arguments to include in the generated command.

Returns

The full command to be passed into a subprocess.

init() → None[source]: Run init.

kubectl_apply() → None[source]

Execute kubectl apply command.

https://kubectl.docs.kubernetes.io/references/kubectl/apply/

kubectl_delete() → None[source]

Execute kubectl delete command.

https://kubectl.docs.kubernetes.io/references/kubectl/delete/

kubectl_kustomize() → str[source]

Execute kubectl kustomize command.

https://kubectl.docs.kubernetes.io/references/kubectl/kustomize/

plan() → None[source]: Run kustomize build and display generated plan.

__getitem__(key: str) → Any

Make the object subscriptable.

Parameters: key – Attribute to get.

__new__(**kwargs)

class runway.module.k8s.K8sOptions[source]

Bases: runway.module.base.ModuleOptions

Module options for Kubernetes.

data

Options parsed into a data model.

Type: runway.config.models.runway.options.k8s.RunwayK8sModuleOptionsDataModel

deploy_environment

Runway deploy environment object.

Type: runway.core.components._deploy_environment.DeployEnvironment

kubectl_version

Version of kubectl to use.

Type: Optional[str]

path

Module path.

Type: pathlib.Path

__init__(data: runway.config.models.runway.options.k8s.RunwayK8sModuleOptionsDataModel, deploy_environment: runway.core.components._deploy_environment.DeployEnvironment, path: pathlib.Path) → None[source]

Instantiate class.

Parameters

deploy_environment – Current deploy environment.
path – Module path.

property kustomize_config: pathlib.Path: Kustomize configuration file.

property overlay_path: pathlib.Path: Directory containing the kustomize overlay to use.

__eq__(other: Any) → bool: Assess equality.

__new__(**kwargs)

static gen_overlay_dirs(environment: str, region: str) → List[str][source]

Generate possible overlay directories.

Prefers more explicit directory name but falls back to environment name only.

Parameters

environment – Current deploy environment.
region – Current AWS region.

get(name: str, default: Optional[Any] = None) → Any: Get a value or return the default.

classmethod get_overlay_dir(path: pathlib.Path, environment: str, region: str) → pathlib.Path[source]: Determine the overlay directory to use.

classmethod parse_obj(deploy_environment: runway.core.components._deploy_environment.DeployEnvironment, obj: object, path: Optional[pathlib.Path] = None) → runway.module.k8s.K8sOptions[source]

Parse options definition and return an options object.

Parameters

deploy_environment – Current deploy environment.
obj – Object to parse.
path – Module path.
