Kubernetes - Namespaces

Given this LimitRange YAML applied in a namespace:

apiVersion: v1
kind: LimitRange
metadata:
  name: mem-limit
spec:
  limits:
  - default:
      memory: "512Mi"
    type: Container

What happens if a pod container is created without specifying memory requests or limits?

AThe container will have no memory limit and can use unlimited memory.

BThe container will have a default memory limit of 512Mi applied automatically.

CThe pod creation will fail due to missing memory limits.

DThe container will have a default CPU limit of 512m applied.

Step-by-Step Solution

Solution:

Step 1: Understand default field in LimitRange
The default field sets default resource limits if none are specified by the container.
Step 2: Apply to memory limit
Since default memory is 512Mi, containers without memory limits get this limit automatically.
Final Answer:
The container will have a default memory limit of 512Mi applied automatically. -> Option B
Quick Check:
default memory limit applied = The container will have a default memory limit of 512Mi applied automatically. [OK]

Quick Trick: default sets resource limits if none specified in pod [OK]
