Actual exam question for Docker's DCA exam
Question #: 106

[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.

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

Setting INSECURE_REGISTRY? Sounds like a great way to invite the hackers to the party. No thank you!

Ah, the age-old question of Docker security. This is a classic case of 'Yeah, you can do it, but should you?'.
