In the create_namespaced_job method there is no parameter that exists to define preStop and postStart handlers.
V1Job create_namespaced_job(namespace, body, pretty=pretty, dry_run=dry_run, field_manager=field_manager)
So, how to add these life-cycle handlers to a job or pod by Python Kubernetes?
In the create_namespaced_job method there is no parameter that exists to define preStop and postStart handlers.
The preStop and postStart handlers exists on the containers. You linked to the documentation for create_namespaced_job and the parameter body is a V1Job, and the spec of that has a template, that has a spec of type V1PodSpec and there you find a field container[list]and there you find a field lifecycle of type V1Lifecylce that has the preStop and postStart-handlers.
The documentation can also be navigated with kubectl explain, e.g:
kubectl explain podTemplate.template.spec.containers.lifecycle
