Docker DCA Exam - Topic 1 Question 106 Discussion

Actual exam question for Docker's DCA exam
Question #: 106
Topic #: 1
[All DCA Questions]

Is this a way to configure the Docker engine to use a registry without a trusted TLS certificate?

Solution. Set INSECURE_REGISTRY in the' /etc/docker/default' configuration file.

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.

I think I remember something about configuring Docker with insecure registries, but I'm not entirely sure if it's done through that specific file.

Okay, let's see. The key here is understanding how to configure the Docker engine to use a registry without a trusted TLS certificate. I think I can figure this out.

Sure, if you want to leave the door open for all the docker daemons to come in and have a field day with your registry. What could possibly go wrong?

Well, if you're running this in a controlled environment and know what you're doing, maybe. But in production? Nope, not a chance.
