Kubernetes - Operators and Custom Resources

You want to create a CRD for a resource named Gadget that is cluster-scoped and has a plural name gadgets. Which YAML snippet correctly defines this?

Aspec: group: example.com scope: Cluster names: kind: Gadget plural: gadget

Bspec: group: example.com scope: Namespaced names: kind: Gadget plural: gadgets

Cspec: group: example.com scope: Cluster names: kind: gadget plural: gadget

Dspec: group: example.com scope: Cluster names: kind: Gadget plural: gadgets

Step-by-Step Solution

Solution:

Step 1: Check scope value
The resource must be cluster-scoped, so scope: Cluster is correct.
Step 2: Verify kind and plural names
kind should be capitalized as Gadget and plural should be gadgets (plural lowercase).
Step 3: Compare options
The snippet with scope: Cluster, kind: Gadget, plural: gadgets matches all requirements. Snippets with scope: Namespaced, lowercase kind: gadget, or singular plural: gadget are incorrect.
Final Answer:
spec: group: example.com scope: Cluster names: kind: Gadget plural: gadgets -> Option D
Quick Check:
Cluster scope + correct kind/plural = spec: group: example.com scope: Cluster names: kind: Gadget plural: gadgets [OK]

Quick Trick: Cluster scope means scope: Cluster; kind capitalized, plural lowercase [OK]

Common Mistakes:

Using Namespaced instead of Cluster scope
Incorrect casing for kind or plural
Using singular for plural name
