Kubernetes cluster fleet viewer
Clusters are the new cattle and we should have tooling available that allows us to quickly get an idea what's going in a fleet of such clusters.
What is this about?
fleet, a simple CLI tool that provides you with the status and configuration of a fleet of Kubernetes clusters. For example:
$ kubectl fleet CLUSTER VERSION NODES NAMESPACES PROVIDER API kind-kind-3 v1.16.3 1/1 4 kind https://127.0.0.1:32769 test-cluster-2 v1.16.2 1/1 4 minikube https://192.168.64.4:8443 kind-test2 v1.16.3 1/1 4 kind https://127.0.0.1:32768 minikube v1.16.2 1/1 4 minikube https://192.168.64.3:8443 gke_krew-release-bot-260708_us-central1-a_standard-cluster-1 v1.15.8-gke.3 3/3 4 GKE https://220.127.116.11 do-sfo2-k8s-1-16-6-do-0-sfo2-1581265844177 v1.16.6 3/3 4 Digital Ocean https://f048f314-4f77-47c2-9264-764da91d35e0.k8s.ondigitalocean.com
Above, you see
fleet used as a
kubectl plugin, available via krew.
The top-level command lists all active clusters found in the kubeconfig
provided. Active clusters are defined as the one that you would see when you'd execute
kubectl config get-contexts command. For each cluster, configuration info such as
the control plane version or API server endpoint are displayed, as well as select
stats, for example, the number of worker nodes or namespaces found in the cluster.
Note that you can also use it standalone, simply download the binary for your platform from the release page.
