Externally poke a pod to wake up

[bkvaluemeal]

For workloads that don't receive ingress traffic, like a Kafka consumer, is there an external way to signal that a pod should be reanimated to, in this example, process messages in a Kafka queue? I'm already using Keda ScaledObject to horizontally scale, but it would be nice to not need to ever terminate the pods.

The only two ways to wake a container is with TCP traffic or via an exec. So while not optimal, you could have something external watch the queue and then exec via the k8s API to signal the container to wake.
