 The log collection for Kubernetes autodiscovered pods can be supported by using  https://github.com/elastic/elastic-agent/tree/main/deploy/kubernetes/elastic-agent-standalone/templates.d/container_logs.yml[container_logs.yml template]. Elastic Agent needs to emit a container_logs mapping so as to start collecting logs for all the discovered containers *even if no annotations are present in the containers*.
