Solution (Step by Step) :
1. Define the Securitycontext in the Deployment YAML:
- Create a 'securityContext' section within the 'spec-template.spec.containerss block for your application container
- Set the 'runAsLJser' field to the desired non-root IJID (e.g., 1000).
- Specify 'allowPrivilegeEscalatiom false' to prevent the container from escalating its privileges beyond the defined CJID.
- Add a 'hostPatm volume mount with 'readOnly: false' to allow the application to read and write to the mounted directory.
- Define a 'volume' with the 'hostPath' type, specifying the source path (e.g., ',/data') and the path within the container where it should be mounted.

2. Create the Deployment: - Apply the Deployment YAML file using 'kubectl apply -f web-app-deployment.yamr 3. Verify the Deployment - Check the status of the Deployment using 'kubectl get deployments web-app'. You should see a running pod with the specified Securitycontext. - Use kubectl describe pod' to inspect the details of the pod and verify that the Securitycontext is applied correctly. 4. Test the Application: - Ensure that your application can access and modify the '/data' volume with the specified user ID (1000). - The 'securitycontext' allows you to define security settings for the application container, such as user ID and privilege escalation- - 'runAsIJsers specifies the IJID under which the container should run. - 'allowPrivilegeEscalation' controls whether the container can elevate its privileges beyond the specified IJID. - 'hostPath' volume mounts allow containers to access directories on the host system. - 'readOnly' determines whether the volume mount iS read-only or read-write. - Ensure your container image has the necessary permissions to access the hostPath volume within the specified UID.
