問題 #104
You nave a Deployment running a web application tnat uses secrets to store sensitive information like database credentials. To improve security, you want to use a secret injection mechanism to provide the secret to the pod without exposing it in the deployment YAML.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Secret:
- Create a secret containing the sensitive information:

2. Configure Deployment to Use Secret: - Update the Deployment YAML to mount the secret into the container:

3. Apply the Configuration: - Apply tne Secret and Deployment configuration: bash kubectl apply -f my-secret.yaml kubectl apply -f my-web-app-deployment.yaml 4. Verify Secret Injection: - Access the secret information from within the container using environment variables: - For example, '$DATABASE_USERNAME and '$DATABASE PASSWORD'.


問題 #105
You are building a web application that uses a set of environment variables for configuration. These variables are stored in a ConfigMap named 'app-config' . How would you ensure that the web application pods always use the latest version of the ConfigMap even when the ConfigMap is updated?

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create the ConfigMap: Define the ConfigMap with your desired environment variables.

2. Update the Deployment: Modify your Deployment YAML file to: - Use a 'volumeMount' to mount the ConfigMap into the container. - Specify a 'volume' using a 'configMap' source, referencing tne 'app-config' ConfigMap. - Set 'imagePullPolicy: Always' to ensure the pod always pulls the latest container image.

3. Apply the changes: Use 'kubectl apply -f deployment-yamp to update the Deployment 4. Llpdate the ConfigMap: Whenever you need to update the configuration, modify the Sapp-config' ConfigMap using 'kubectl apply -f configmap-yamr 5. Verify changes: Observe the pods for the 'web-app' Deployment. They should automatically restart and pick up the new environment variables from the updated ConfigMap. By setting 'imagePullPolicy: AlwayS , your pods will always pull the latest container image- This ensures that the pod's container always uses the latest code. Additionally, the 'volumeMount' and 'volume detinitions mount tne Sapp-config' ConfigMap into the containers 'letc/config' directory, making the environment variables accessible within the container When you update the ConfigMap, the pod will detect the change and automatically restart, loading the new configuration from the updated ConfigMap. ,


問題 #106

Task:
1) Create a secret named app-secret in the default namespace containing the following single key-value pair:
Key3: value1
2) Create a Pod named ngnix secret in the default namespace.Specify a single container using the nginx:stable image.
Add an environment variable named BEST_VARIABLE consuming the value of the secret key3.

答案：

Solution:



問題 #107
You are tasked with setting up a secure Kubernetes cluster for a web application. The application has sensitive data that must be protected. You need to configure a mecnanism to restrict access to the application's pods based on user identities. Describe a method to achieve this using Kubernetes RBAC and Service Accounts, ensuring that only authorized users can access specific pods.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Service Account
- Create a Service Account for the application:

- Apply the Service Account configuratiom basn kubectl apply -f webapp-sa.yaml 2. Create a Role: - Define a Role that grants access to the specific pods:

- Apply the Role configuratiom bash kubectl apply -f webapp-pod-reader.yaml 3. Create a RoleBinding: - Bind the Role to the Service Account

- Apply the RoleBinding configuration: bash kubectl apply -f webapp-pod-reader-binding_yaml 4. Configure the Application: - When deploying the application, specify the Service Account:

5. Verify Access: - Use the 'kubectr command with the Service Account's credentials to verify that only authorized users can access the application's pods: bash kubectl -service-account=webapp-sa get pods -n This setup utilizes Kubernetes RBAC to control access to the application's pods. - The Service Account acts as an identity for the application. - The Role defines the permissions granted to the Service Account, specifically allowing access to the pods. - The RoleBinding associates the Role with the Service Account, linking the permissions to the identity. - When the application is deployed witn tne specified Service Account, it inherits the permissions defined in the RoleBinding. This ensures that only users with the necessary credentials (associated with the Service Account) can access and interact with the application's pods, safeguarding sensitive data.
