Docker Exam DCA Topic 2 Question 104 Discussion

Actual exam question for Docker's DCA exam
Question #: 104
Topic #: 2
[All DCA Questions]

You want to provide a configuration file to a container at runtime. Does this set of Kubernetes tools and steps accomplish this?

Solution: Turn the configuration file into a configMap object and mount it directly into the appropriate pod and container using the .spec.containers.configMounts key.

Show Suggested Answer Hide Answer
Suggested Answer: A

The provided Kubernetes NetworkPolicy YAML configuration indicates that the policy applies to pods with the label tier: backend in the default namespace1. The ingress rule allows traffic from pods with the label tier: api1. Therefore, a request issued from a pod bearing only the tier: frontend label to a pod bearing the tier: backend label will be blocked by this networkPolicy1. This is because the networkPolicy does not have a rule allowing ingress from pods with the tier: frontend label1. For more information on Kubernetes NetworkPolicies, you can refer to the Kubernetes Documentation on Network Policies.

Yep, that's definitely the way to go. Can't wait to use this in my next Kubernetes project and look like a total pro.

Haha, I was just about to suggest the same thing. It's like they read my mind! Guess I'll have to come up with a different strategy for the exam.

I agree, this solution seems to be correct. Configuring the container with a configMap is a common and effective way to handle runtime configuration.

Yes, this looks like the right approach to me. Mounting a configMap directly into the container is a great way to provide runtime configuration.

I'm not sure, I think we need to double check the steps.
