How should you configure a Deployment in Google Kubernetes Engine (GKE) to include a database connection check and ensure a graceful shutdown with a container script if the connection fails?
(Optionally include a corrected code block if the original contained syntax errors or typos related to liveness/readiness probes or lifecycle hooks.)
A
Create two jobs: one that checks whether the container can connect to the database, and another that runs the shutdown script if the Pod is failing.
B
Create the Deployment with a livenessProbe for the container that will fail if the container can't connect to the database. Configure a Prestop lifecycle handler that runs the shutdown script if the container is failing.
C
Create the Deployment with a PostStart lifecycle handler that checks the service availability. Configure a PreStop lifecycle handler that runs the shutdown script if the container is failing.
D
Create the Deployment with an initContainer that checks the service availability. Configure a Prestop lifecycle handler that runs the shutdown script if the Pod is failing.
