Does SLD worker wait all tasks done when receive signal signal.SIGTERM from k8s or docker ? about stack-lifecycle-deployment HOT 1 CLOSED

Hi @dehengxu
When a Celery worker, acting as an "SLD worker," receives a SIGTERM signal from Kubernetes (k8s) or Docker, its behavior depends on its configuration and the nature of Celery's task management.

By default, upon receiving a SIGTERM signal, a Celery worker initiates a graceful shutdown process. This means it attempts to finish all the tasks it is currently processing before shutting down. It will not accept new tasks but will try to complete those that have already started. This behavior is crucial to ensure that tasks are not abruptly interrupted, which could lead to inconsistent states or data loss.

However, it's important to note that this orderly shutdown process has a time limit. If the tasks do not complete within this period, the worker will shut down anyway, potentially leaving some tasks incomplete.

In summary, a Celery worker receiving a SIGTERM signal tries to complete its ongoing tasks before shutting down, but if these tasks are not completed within a certain time frame, it will shut down regardless.
If you provide me with more context about the problem you have or what you want to resolve, I may be able to assist you further.
