A Kubernetes cluster has an existing database Deployment running. Configure a new web Deployment to schedule its pods only on nodes where the database pods are already running using required pod affinity.
A Kubernetes cluster has tainted nodes to restrict pod scheduling. Configure a Deployment to schedule pods exclusively on a specific tainted node using both tolerations and required node affinity.
Deploy a multi-container Kubernetes Deployment and ensure that no more than one Pod runs on the same worker node, without using a DaemonSet.
Troubleshoot and update a Kubernetes DaemonSet so that its Pods run on all nodes in the cluster, including the control plane.
