In this question, we are asked to create a multi-container pod with a set of requirements.
In the grading of the exam, it’s not clear to me why the following are marked as 
for me when the kubectl describe seems to show the items done correctly.
Is the primero container use busybox:1.28 image
Is the primero container environment variable well configured
Does the segundo container use nginx:1.17
Is the segundo container expose at port 8080
Is the tercero container environment variable well configured?
Here is my kubectl describe output:

Would love some insight as to what I missed.
