## Improve connection draining when ingress controller pod is deleted using a lifecycle hook:
|
||||||
lifecycle: {}
|
## With this new hook, we increased the default terminationGracePeriodSeconds from 30 seconds
|
||||||
|
## to 300, allowing the draining of connections up to five minutes.
|
||||||
|
## If the active connections end before that, the pod will terminate gracefully at that time.
|
||||||
|
## To efectively take advantage of this feature, the Configmap feature
|
||||||
|
## worker-shutdown-timeout new value is 240s instead of 10s.
