What registry permissions does OpenShift cluster node require?

AOnly the master nodes ever require registry access.

BOnly the bastion node should be able to reach the registry.

CWhile the bastion node pushes to the private registry, only the worker nodes pull images.

DAll nodes must be able to push to and pull from the registry.

Show Suggested Answer

Suggested Answer: D

In an OpenShift environment that hosts IBM Cloud Pak for Data, all cluster nodes---including master and worker nodes---must have access to the container registry to pull required images during deployment and runtime. In scenarios involving custom images, some nodes may also need to push to the registry. While the bastion node may initiate the setup or mirror images, it is not the only node involved. Therefore, all nodes should be configured with both pull and, where applicable, push access to the registry to ensure consistent deployment and operations.

I feel like option A is too limiting. Master nodes need help!

Option C sounds good too. Bastion pushes, workers pull.

But isn't it risky to let all nodes push?

I think option D makes the most sense. All nodes need access.

B sounds too restrictive, all nodes should have access for efficiency!

D) All nodes must be able to push to and pull from the registry. Seems like the most logical answer to me.

I believe the correct answer is that all nodes must push and pull, but I need to double-check that.

I feel like we practiced a question similar to this, and I think it was about worker nodes only pulling images.

I think I remember that all nodes need access to the registry, but I'm not entirely sure if they all need to push as well.

I'm feeling pretty confident about this one. I'll systematically evaluate each answer choice against my understanding of OpenShift node roles and registry permissions.
