get obj

Author: Kobi Carmeli

Get object's yaml and image from an existing k8s resource such as deployment or statefulset. Develop, live update and debug against applications that were already deployed to Kubernetes from CI/CD or other tools.

get_obj(name: str, kind: str, container_selector: str, namespace: str, disable_probes: bool)

• name: The object's name as you would express it to kubectl. e.g my-deployment.
• kind: The object's kind. e.g 'deployment' or 'statefulset'
• container_selector: The container name in the pod that will be used for remote development.
• namespace?: The namespace of the object. If not specified, uses the current namespace.
• disable_probes?: Disable liveness and readiness probes by removing them from the deployment, which is useful when debugging node applications. Default: False.
