The error message:
python
Copy
failed to list clusters: command "docker ps -a --filter label=io.x-k8s.kind.cluster --format '{{.Label "io.x-k8s.kind.cluster"}}'" failed with error: exit status 1
indicates that the command failed while attempting to list docker containers with the given filter. The kind tool (used for creating a bootstrap cluster) depends on Docker as the container runtime.
Root cause:
If Docker is not running or a compatible container runtime is not available (such as containerd), the kind tool cannot list or interact with the required containers, resulting in this error.
Key Reference:
“When creating bootstrap clusters, the kind tool requires Docker to be installed and running. If Docker is not running, errors will be encountered listing or interacting with containers.”

Although the team was experienced, the manual management for cluster health checking was becoming increasingly complicated and prone to errors., The team consulted its company’s Platform Engineer on how to best address these issues. They told the engineer that events such as these were occurring, 1.Omitting pod security standards., 2.Crashlooping cases., 3.Failed nodes when deploying or running kube-bench., What recommendation should the engineer provide to the DevOps team?, A.Run the nkp describe cluster --cluster-name=${CLUSTER_NAME} command., B.Use override ConfigMaps to configure alert rules., C.Create a MachineHealthCheck resource in YAML format., D.Use AlertManager and NKP Insights together., Answer:D, ]
