* Update check.go Added new warn_reason value which gives a brief explanation about why the not scored tests failed * Update common.go Changed when a not scored test fails because it has a wrong syntax audit command or just running something that can't be run the print the failure. but if the test just fails because it doesn't line up with the cis hardening recommendations then print the remediation text. * Update check/check.go fix typo Co-Authored-By: Liz Rice <liz@lizrice.com> * Update check.go * Update common.go * Update check.go added back os.Exit(1) to exitWithError * Update job-master.data Change some tests output to fit warn reason. (No change to the summary) * Update job-node.data Changed some tests output to fit warn reason. (No change to the summary) * Update job.data Change some tests output to fit warn reason. (No change to the summary) * Update common.go Keep to old way to print manual test output Co-authored-by: Liz Rice <liz@lizrice.com> Co-authored-by: Roberto Rojas <robertojrojas@gmail.com>

2.1.4 If using a Kubelet config file, edit the file to set readOnlyPort to 0 .
|
|
If using command line arguments, edit the kubelet service file
|
|
/etc/systemd/system/kubelet.service.d/10-kubeadm.conf on each worker node and
|
|
set the below parameter in KUBELET_SYSTEM_PODS_ARGS variable.
|
|
--read-only-port=0
|
|
Based on your system, restart the kubelet service. For example:
|
|
systemctl daemon-reload
|
|
systemctl restart kubelet.service
|
|
|
|
2.1.6 If using a Kubelet config file, edit the file to set protectKernelDefaults: true .
|
|
If using command line arguments, edit the kubelet service file
|
|
/etc/systemd/system/kubelet.service.d/10-kubeadm.conf on each worker node and
|
|
set the below parameter in KUBELET_SYSTEM_PODS_ARGS variable.
|
|
--protect-kernel-defaults=true
|
|
Based on your system, restart the kubelet service. For example:
|

/etc/systemd/system/kubelet.service.d/10-kubeadm.conf on each worker node and
|
|
set the below parameter in KUBELET_SYSTEM_PODS_ARGS variable.
|
|
--event-qps=0

|
|
|
|
2.1.10 If using a Kubelet config file, edit the file to set tlsCertFile to the location of the certificate
|
|
file to use to identify this Kubelet, and tlsPrivateKeyFile to the location of the
|
|
corresponding private key file.
|
|
If using command line arguments, edit the kubelet service file
|
|
/etc/systemd/system/kubelet.service.d/10-kubeadm.conf on each worker node and
|
|
set the below parameters in KUBELET_CERTIFICATE_ARGS variable.
|
|
--tls-cert-file=<path/to/tls-certificate-file>
|
|
file=<path/to/tls-key-file>

|
|
|
|
2.1.13 Edit the kubelet service file /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
|
|
on each worker node and set the below parameter in KUBELET_CERTIFICATE_ARGS variable.
|
|
--feature-gates=RotateKubeletServerCertificate=true
|
|
Based on your system, restart the kubelet service. For example:
|
|
systemctl daemon-reload
|
|
systemctl restart kubelet.service

|
|
|
2.2.5 Run the below command (based on the file location on your system) on the each worker
|
|
node. For example,
|
|
chmod 644 /etc/kubernetes/proxy.conf
|
|
|
|
2.2.6 Run the below command (based on the file location on your system) on the each worker
