Deploy a multi-container Kubernetes Deployment and ensure that no more than one Pod runs on the same worker node, without using a DaemonSet.
A Deployment is failing because application configuration is missing. Mount only specific keys from an existing ConfigMap as files inside the Pod at the correct path so the application can start successfully.
Configure a Vertical Pod Autoscaler (VPA) with a per-container resource policy that provides recommendations for the main container while excluding the sidecar container from any VPA-managed scaling.
Create a ResourceQuota to limit resource consumption and object counts in a namespace, then deploy a compliant application with Burstable QoS.
