Question

Given a partially-functioning Kubernetes cluster, identify symptoms of failure on the cluster. Determine the cause, the failing service, and take actions to bring up the failed service and restore the health of the cluster. Ensure that any changes are made permanently. You can ssh to the relevant nodes (bk8s-master-0 or bk8s-node-0) using: [student@node-1] $ ssh <nodename> You can assume elevated privileges on any node in the cluster with the following command: [student@nodename] $ sudo -i You may use any CNI plugin to complete this task, but if you don't have your favourite CNI plugin's manifest URL at hand, Calico is one popular option: https://docs.projectcalico.org/v3.14/manifests/calico.yaml Docker is already installed on both nodes and apt has been configured so that you can install the required tools.
