Task
The alpine Deployment in the alpine namespace has three containers that run different versions of the alpine image.
First, find out which version of the alpine image contains the libcrypto3 package at version 3.1.4-r5.
Next, use the pre-installed bom tool to create an SPDX document for the identified image version at /home/candidate/alpine.spdx.
You can find the bom tool documentation at bom.
Finally, update the alpine Deployment and remove the container that uses the idenfied image version.
The Deployment's manifest file can be found at /home/candidate/alpine-deployment.yaml.
Do not modify any other containers of the Deployment.
