Create a RuntimeClass named gvisor-rc using the prepared runtime handler named runsc.
Create a Pods of image Nginx in the Namespace server to run on the gVisor runtime class
答案：
解題說明：
Install the Runtime Class for gVisor
{ # Step 1: Install a RuntimeClass
cat <<EOF | kubectl apply -f -
apiVersion: node.k8s.io/v1beta1
kind: RuntimeClass
metadata:
name: gvisor
handler: runsc
EOF
}
Create a Pod with the gVisor Runtime Class
{ # Step 2: Create a pod
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Pod
metadata:
name: nginx-gvisor
spec:
runtimeClassName: gvisor
containers:
- name: nginx
image: nginx
EOF
}
Verify that the Pod is running
{ # Step 3: Get the pod
kubectl get pod nginx-gvisor -o wide
}
問題 #15
You are managing a Kubernetes cluster with a deployment named 'web-app' that runs multiple pods. These pods access a database hosted on a separate Kubernetes service named 'database-service'. You need to ensure that the pods can only connect to the database service and are restricted from accessing other services in the cluster.
答案：
解題說明：
Solution (Step by Step) :
1. Create a Network Policy:
- Create a Network Policy YAML file named 'web-app-policy.yaml with the following content
2. Apply the Network Policy: - Apply the policy using Skubectl apply -f web-app-policy.yamr 3. Verify the Network Policy: - Check the status of the Network Policy using 'kubectl get networkpolicieS to confirm that it has been applied. 4. Test the Connectivity: - Try to access the database service from a pod in the 'web-apps deployment. - Attempt to access other services from the same pod. - You should only be able to access the 'database-service' due to the Network Policy restrictions.
問題 #16
You are tasked with securing a Kubernetes cluster where sensitive data is stored in ConfigMaps- The ConfigMaps are accessed by various applications running in pods, some of which are located in the 'default' namespace. You need to prevent unauthorized access to these ConfigMaps
How would you leverage Role-Based Access Control (R8AC) to restrict access to ConfigMaps, ensuring only authorized pods in the 'default namespace can access specific ConfigMaps?
答案：
解題說明：
Solution (Step by Step) :
1. Define a Role: Create a Role named 'configmap-readerw in the 'default namespace that allows access to only specific ConfigMaps:
2. Bind the Role to a ServiceAccount: Create a ServiceAccount named 'configmap-app-sa' in the 'default' namespace and bind tne 'configmap- reader Role to it:
3. Configure Pods to use the ServiceAccount: update tne POdS running in the 'defaults namespace that need access to tnese ConfigMaps to use the 'configmap-app-sa' ServiceAccount:
The 'configmap-reader' Role grants access to the specific ConfigMaps ('sensitive-data' , Sapp-config') to pods that have the associated ServiceAccount. The 'configmap-app-sa-binding' binds this Role to the 'configmap-app-sa' ServiceAccount. PodS using this ServiceAccount Will only nave access to tne allowed ContigMaps and are restricted from accessing other ConfigMaps. Note: This approach ensures that only authorized pods in the 'default namespace can access specific ConfigMaps. You should adjust the 'resourceNameS in the Role definition to include the specific ConfigMaps that you want to restrict access to. Make sure the ServiceAccount used by the pods is granted the appropriate permissions to access the ConfigMaps. This example demonstrates how to use RBAC to restrict access to ConfigMaps, ensuring only authorized pods can access sensitive data. You should adjust the permissions and service accounts as needed to meet your specific security requirements.

Fix all issues via configuration and restart the affected components to ensure the new setting takes effect.
Fix all of the following violations that were found against the API server:- a. Ensure that the RotateKubeletServerCertificate argument is set to true.
b. Ensure that the admission control plugin PodSecurityPolicy is set.
c. Ensure that the --kubelet-certificate-authority argument is set as appropriate.
Fix all of the following violations that were found against the Kubelet:- a. Ensure the --anonymous-auth argument is set to false.
b. Ensure that the --authorization-mode argument is set to Webhook.

Follow the documentation and create Pod Security Policy objects as per your environment.
Then, edit the API server pod specification file $apiserverconf
on the master node and set the --enable-admission-plugins parameter to a value that includes PodSecurityPolicy :
--enable-admission-plugins=...,PodSecurityPolicy,...
Then restart the API Server.
scored: true
c. Ensure that the --kubelet-certificate-authority argument is set as appropriate.
audit: "/bin/ps -ef | grep $apiserverbin | grep -v grep"
tests:
test_items:
- flag: "--kubelet-certificate-authority"
set: true
remediation: |
Follow the Kubernetes documentation and setup the TLS connection between the apiserver and kubelets. Then, edit the API server pod specification file
$apiserverconf on the master node and set the --kubelet-certificate-authority parameter to the path to the cert file for the certificate authority.
--kubelet-certificate-authority=<ca-string>
scored: true
Fix all of the following violations that were found against the ETCD:-
a. Ensure that the --auto-tls argument is not set to true
Edit the etcd pod specification file $etcdconf on the master
node and either remove the --auto-tls parameter or set it to false.
--auto-tls=false
b. Ensure that the --peer-auto-tls argument is not set to true
Edit the etcd pod specification file $etcdconf on the master
node and either remove the --peer-auto-tls parameter or set it to false.
--peer-auto-tls=false
