Graceful shutdown for container based gateway pod

Products

• CA API Gateway

Issue/Introduction

we are currently working on stability of our system during platform upgrades. As part of this we are looking forward to gracefully shutdown our gateway pods using k8s lifecycle prestop phase via helm chart leveraging any existing shell script for the same.

Resolution

At the moment there is not a option to gracefully shutdown the gateway pod by disabling the incoming traffic and gracefully shutdown the gateway process.

There is a shutdown script which checks incoming connection status and if there are active connections we delay the shutdown of the pod.

Engineering is looking to improve this in a future release .
