Linux Foundation CKS Exam - Topic 3 Question 73 Discussion

Actual exam question for Linux Foundation's CKS exam
Question #: 73
Topic #: 3
[All CKS Questions]

Context

A container image scanner is set up on the cluster, but it's not yet fully integrated into the cluster s configuration. When complete, the container image scanner shall scan for and reject the use of vulnerable images.

Task

Given an incomplete configuration in directory /etc/kubernetes/epconfig and a functional container image scanner with HTTPS endpoint https://wakanda.local:8081 /image_policy :

1. Enable the necessary plugins to create an image policy

2. Validate the control configuration and change it to an implicit deny

3. Edit the configuration to point to the provided HTTPS endpoint correctly

Finally, test if the configuration is working by trying to deploy the vulnerable resource /root/KSSC00202/vulnerable-resource.yml.

I’m a bit confused about editing the configuration to point to the HTTPS endpoint. Is it just a matter of changing the URL in the config file?

I think we practiced something similar where we had to set an implicit deny. It’s about making sure no vulnerable images are allowed, right?

I've worked with image scanning and policy enforcement before, so I think I've got a good handle on this. The key will be making sure I enable the right plugins and configure the HTTPS endpoint correctly. Shouldn't be too much of a challenge.

Okay, let's break this down step-by-step. First, I'll need to enable the necessary plugins, then set the policy to implicit deny, and finally update the config to point to the HTTPS endpoint. Shouldn't be too difficult, just need to be careful with the details.

This looks like a pretty straightforward configuration task. I think I can handle it - just need to enable the right plugins, set the policy to implicit deny, and point to the HTTPS endpoint correctly.
