## Description
The Managed Lifecycle pattern uses postStart and preStop hooks to manage container lifecycle events. PostStart hooks execute immediately after container creation, while preStop hooks run before container termination. These hooks enable tasks like initialization, cleanup, or graceful shutdown processes that need to be tightly integrated with the container lifecycle.


## Use Cases
Use when you need to perform actions during container startup or shutdown or when you need graceful shutdown processes.





## Trade-offs


### Advantages

- Tight integration with container lifecycle

- Enables initialization and cleanup tasks

- Supports graceful shutdown

- Automates lifecycle management




### Considerations & Drawbacks

- Hook execution is asynchronous and best-effort

- Cannot guarantee execution order

- May not complete before termination
