Query Kubernetes
Rely on cnquery to explore and analyze your entire Kubernetes stack. You can query any type of Kubernetes deployment, whether it's local or in the cloud. cnquery lets you gather data about all aspects of your container infrastructure and their workloads.
cnquery provides the answers you need about every Kubernetes configuration. For a list of Kubernetes resources you can query, read Mondoo Kubernetes (K8s) Resource Pack Reference and Mondoo Core Resource Pack Reference.
Connect cnquery with your Kubernetes environment
Requirements
To analyze and explore your Kubernetes environment with cnquery, you must have:
- cnquery installed on your workstation.
- kubectl installed on your workstation. To ensure that kubectl is successfully installed and you can access your Kubernetes infrastructure, run
kubectl describe nodes.
Verify with a quick Kubernetes query
To quickly confirm that cnquery has access to your Kubernetes environment, run this query from your terminal:
cnquery run k8s -c k8s.deployment
cnquery returns a list of found deployments:
k8s.deployment: k8s.deployment namespace="kube-system" name="coredns" created=2022-12-14 15:17:37 -0800 PST
k8s.deployment: k8s.deployment namespace="luna" name="luna-frontend" created=2022-12-14 15:28:23 -0800 PST
k8s.deployment: k8s.deployment namespace="luna" name="postgres" created=2022-12-14 15:28:48 -0800 PST
Next step
You've successfully used cnquery to answer your first question about your Kubernetes infrastructure. Now you're ready to explore more Kubernetes information.
