I'm having trouble with finding a solution that allows to terminate only certain pods in a deployment.
The application running inside the pods does some processing which can a take lot of time to be finished.
Let's say I have 10 tasks that are stored in a database and I issue a command to scale the deployment to 10 pods.
Let's say that after some time 3 of the pods have finished their tasks and are no longer required. How can i scale down the deployment from 10 to 7 while terminate only the pods that have finished the tasks and not the pods that are still processing those tasks?
I don't know if more details are needed but i will happily edit the question if there are more details needed to give an answer for this kind of problem.
In this case Kubernetes Job might be better suited for this kind of task.
