Lists Kubernetes info and deployed resources across all namespaces in the current cluster / kube context
|
|
|
|
Can optionally specify a different kubernetes context to switch to (will switch back to original context on any exit except kill -9)
|
|
|
|
Lists:
|
|
|
|
- cluster-info
|
|
- master component statuses
|
|
- nodes
|
|
- namespaces
|
|
- deployments, replicasets, replication controllers, statefulsets, daemonsets, horizontal pod autoscalers
|
|
- services, ingresses
|
|
- jobs, cronjobs
|
|
- storage classes, persistent volumes, persistent volume claims
|
|
- service accounts, resource quotas, network policies, pod security policies
|
|
- container images running
|
|
- container images running counts descending
|
|
- pods # might be too much detail if you have high replica counts, so done last, comment if you're sure nobody has deployed pods outside deployments
