NEW QUESTION # 173
Context
Anytime a team needs to run a container on Kubernetes they will need to define a pod within which to run the container.
Task
Please complete the following:
* Create a YAML formatted pod manifest
/opt/KDPD00101/podl.yml to create a pod named app1 that runs a container named app1cont using image Ifccncf/arg-output with these command line arguments: -lines 56 -F
* Create the pod with the kubect1 command using the YAML file created in the previous step
* When the pod is running display summary data about the pod in JSON format using the kubect1 command and redirect the output to a file named /opt/KDPD00101/out1.json
* All of the files you need to work with have been created, empty, for your convenience

NEW QUESTION # 174
You are running a Kubernetes cluster that manages a critical web application. Your application uses a custom resource called 'Database' to represent database instances. You want to ensure that only authorized users within your organization can create and manage these database instances. How would you implement this using ServiceAccounts and Role-Based Access Control (RBAC)?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a ServiceAccount:
- Create a ServiceAccount specifically for managing database instances. This ServiceAccount will be assigned to the users authorized to work with databases.

- Apply the ServiceAccount to your cluster using 'kubectl apply -f serviceAccount.yamI' 2. Create a Role: - Define a Role to specify the permissions that the 'database-manager' ServiceAccount should have. This Role will allow the ServiceAccount to create, update, delete, and list 'Database custom resources.

- Apply the Role using 'kubectl apply -f role.yamr 3. Bind the Role to the ServiceAccount - Use a RoleBinding to link the 'database-managers ServiceAccount to the 'database-manager-roles

- Apply the RoleBinding using 'kubectl apply -f roleBinding.yaml' 4. Use the ServiceAccount: - When users need to manage database instances, they should authenticate to the Kubernetes cluster using credentials associated with the 'database-manager ServiceAccount This will grant them the permissions defined in the Role. - Example: - 'kubectl create database my-database Important Notes: - Replace "'your-group"' and '"your-namespace"' with the actual values for your custom resource and namespace, respectively. - You might need to create a ClusterRole instead of a Role if you want the permissions to apply across all namespaces in your cluster. - This example assumes you've already defined the CustomResourceDefinition (CRD) for the 'Database' resource.]


NEW QUESTION # 175
You have a Helm cnan named 'my-app' that deploys a web application. The chan uses a 'service' and 'deployment' to expose the application. However, the chart currently deploys the application using a static 'image: my-app:v1.0.0' in the 'deployment section. How can you modify the Helm chan to dynamically pull the latest image tag from a Git tag tor the 'my-app' repository?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Configure Git Tag as Image Tag:
- In your 'my-app/values.yamr, add a new variable to hold the desired Git tag:

2. Modify the Deployment Template:


3. Fetch Git Tag using 'helm template's - Before deploying the chart, use 'helm template to generate the template with the Git tag injected. Assuming your Git repository is named 'my-repo' and the tag iS 'vl.1.0', run: bash helm template my-app -set image-tag=$(git Is-remote --tags my-repo I grep vl .1.0 | awk '{print $2}' | cut -f3) 4. Deploy the Chart: - Now you can deploy the Helm chart using the generated template or by setting the 'image-tag' value directly in the 'helm install' command. For example: bash helm install my-app my-appl --set image.tag=S(git Is-remote -tags my-repo I grep v1.1.0 | awk '{print $2)' | cut -d'/' -f3) - When deploying, the chart will automatically use the specified Git tag as the image tag for the deployment.


NEW QUESTION # 176
You are deploying a new microservice called 'payment-service' that requires access to a confidential data volume mounted at /sensitive- data'. This volume is mounted as a Secret in Kubernetes. The 'payment-service' container should only be allowed to access this volume. You need to configure the PodSecurityPolicy to enforce this access restriction.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Create a PodSecurityPoIicy:
- Create a YAML file for your P0dSecurityP01icy.
- Define the 'apiVersion' and 'kind'
- Add a 'metadata' section with a unique name for the policy (e.g., 'payment-service-psp').
- In the 'spec' section:
- Set 'runAsUser' to ' RunAsAny' to allow any user ID.
- Set readOnlyRootFilesystem' to 'talse' to allow modifications within the container.
- Set 'hostNetworR to 'false' to avoid using the host's network.
- Set 'allowPrivilegeEscalatiorU to 'false' to prevent privilege escalation.
- In the 'volumes' sectiom
- Define 'hostPath' as the allowed volume type with the specified path "Isensitive-data'

2. Apply the PodSecurityPolicy: - Use ' kubectl apply -f payment-service-psp.yamr to create the PodSecurityPoIicy in your cluster. 3. Create a ServiceAccount: - Create a new ServiceAccount tor the 'payment-service deployment. - Apply the ServiceAccount YAML file using 'kubectl apply -f payment-service-sa_yamr 4. Bind the PodSecurityPolicy to the ServiceAccount: - Create a RoleBinding to bind the 'payment-service-psp' to the 'payment-service' ServiceAccount - Apply the RoleBinding YAML file using "kubectl apply -f payment-service-rb.yaml'

5. Deploy the Payment Service: - Create the 'payment-service' Deployment configuration. - Specify the 'payment-service' ServiceAccount in the field. - Define the 'volumeMount tor the 'sensitive-data' volume and specify the corresponding 'volume' in the 'volumes' section. - Ensure the volume is mounted as a Secret from the 'default' namespace.

- The PodSecurityPolicy restricts the benavior of pods and their containers. - 'runAslJser' , 'readOnlyRootFilesystem', 'hostNetwork' , and sallowPrivilegeEscalation' define various security constraints for the container. - The 'volumes' section specifies allowed volume types (e.g., 'hostPath') and paths. - The ServiceAccount binds the PodSecurityPolicy to the deployment. - The ROIeBinding assigns the PodSecurityPolicy to the ServiceAccount, effectively enforcing the specified constraints. This configuration ensures that only the payment-service' deployment can access the confidential data volume mounted as a Secret in Kubernetes.


NEW QUESTION # 177
Exhibit:

Task
You are required to create a pod that requests a certain amount of CPU and memory, so it gets scheduled to-a node that has those resources available.
* Create a pod named nginx-resources in the pod-resources namespace that requests a minimum of 200m CPU and 1Gi memory for its container
* The pod should use the nginx image
* The pod-resources namespace has already been created
