Explanation:
Solution (Step by Step) :
1. Create a Secret for the Configuration File:
- Create a Kubernetes Secret to store the 'config.json' file securely. This will ensure that the configuration data is encrypted and stored in a way that is not accessible directly by users or processes within the pod.
- Use the following command to create the Secret:
bash
kubectl create secret generic config-secret -from-file-config .json=configjson
2. Mount the Secret as a Volume:
- In your Deployment YAML, mount the 'contig-secret' as a volume to the pod. This will make the secret's content available to the pod.
- Define the volume mount in the 'spec-template-spec-containers' section of your Deployment YAML:

3. Restrict Access using Security Context: - Define a 'securityContexts for the container in your Deployment YAML. This will restrict the container's capabilities and permissions. - Add a 'securitycontext' section to the section of your Deployment YAML:

4. Limit the Container's Capabilities: - Configure the 'capabilities' section within the 'securityContexts to restrict the container's access to specific system capabilities. This is essential for limiting the containers ability to access sensitive information or perform privileged operations. - Add a 'capabilities' section to the 'spec-template-spec-containers-securitycontext' section of your Deployment YAML:

5. Apply the Deployment: - Once tne Deployment configuration is updated, apply it to the cluster using the following command: bash kubectl apply -f deployment.yaml By implementing these steps, you ensure that the 'config.json' file is secured using a Kubernetes Secret, mounted as a volume, and access is restricted using security context and capabilities settings. This effectively protects the sensitive configuration from unauthorized access within the pod.
