NEW QUESTION # 168
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 # 169
You have a Kubernetes cluster with a Deployment named 'my-app' that runs a web application. You want to restrict access to this application to only specific users within your organization. How would you use Service Accounts and RBAC to implement this?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create a Service Account:
- Create a new Service Account specifically for your application:

- Apply this YAML file using 'kubectl apply -f my-app-sa.yaml'. 2. Create a Role: - Define a Role that grants specific permissions to the Service Account. For example, you might want to grant read access to the Deployment's secrets:

- Apply this YAML file using 'kubectl apply -f my-app-reader.yaml' 3. Bind the Role to the Service Account: - Create a RoleBinding that associates the 'my-app-reader' Role with the 'my-app-sa' Service Account:

- Apply this YAML file using 'kubectl apply -f my-app-sa-binding.yaml' 4. Update the Deployment: - Update the 'my-app' Deployment to use the new Service Account:

- Apply the updated Deployment configuration using 'kubectl apply -f my-app.yaml'. 5. Verify: - Ensure that pods within the 'my-app' Deployment are running with the correct Service Account. You can use 'kubectl get pods -l app=my-app -o wide' to inspect the pod details. 6. Restricting Access to Specific Users: - To restrict access to the application to specific users within your organization, you would need to: - Configure a more granular Role to grant specific access levels (e.g., read-only, edit, etc.). - Use a Kubernetes authentication provider (such as OAuth2 or OpenID Connect) to authenticate and authorize users. - Bind the Role to the user's identity, ensuring they have the appropriate permissions. Important Note: This example provides a basic setup for RBAC with Service Accounts. In real-world scenarios, you might need to configure more complex RBAC rules to address your specific security requirements and user access control policies.]


NEW QUESTION # 170
You have a ConfigMap named 'database-config' tnat stores sensitive information for connecting to a database. You want to ensure that this ConfigMap is only accessible by a specific namespace and not by other namespaces in the cluster.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Namespace:
bash
kubectl create namespace my-database-namespace
2. Move the ConfigMap to the Namespace:
bash
kubectl move configmap database-config -n my-database-namespace
3. Configure Role-Based Access Control (RBAC):
- Create a Role:

- Create a RoleBinding:

- Replace 'my-service-account with the actual name of the service account that needs access to the ConfigMap. 4. Apply the Role and Role3inding: bash kubectl apply -f database-config-reader.yaml kubectl apply -f database-config-reader-binding.yaml 5. Verify Access: - From the 'my-database-namespace': bash kubectl get configmap database-config -n my-database-namespace The command should succeed as the service account in this namespace has the necessary permissions. - From a different namespace: bash kubectl get configmap database-config -n another-namespace This command should fail as the service account in this namespace does not have access to the ConfigMap. This solution uses RBAC to restrict access to the ConfigMap to only the service account in the 'my-database-namespace'. This ensures that sensitive information is only accessible by authorized entities within the cluster,


NEW QUESTION # 171
