[desk@cli] $ kubectl config use-context dev
Context:
A CIS Benchmark tool was run against the kubeadm created cluster and found multiple issues that must be addressed.
Task:
Fix all issues via configuration and restart the affected components to ensure the new settings take effect.
Fix all of the following violations that were found against the API server:
1.2.7 authorization-mode argument is not set to AlwaysAllow FAIL
1.2.8 authorization-mode argument includes Node FAIL
1.2.7 authorization-mode argument includes RBAC FAIL
Fix all of the following violations that were found against the Kubelet:
4.2.1 Ensure that the anonymous-auth argument is set to false FAIL
4.2.2 authorization-mode argument is not set to AlwaysAllow FAIL (Use Webhook autumn/authz where possible) Fix all of the following violations that were found against etcd:
2.2 Ensure that the client-cert-auth argument is set to true
