Kubernetes - Helm Package Manager

A Helm chart template uses this code:

{{ .Values.image.tag | default "latest" }}

But the rendered manifest shows tag: with no value. What is the problem?

AThe <code>image.tag</code> key exists but is set to an empty string, so default is ignored.

BThe <code>default</code> function is used incorrectly and should be <code>or</code>.

CThe <code>image.tag</code> key is missing, so default should apply but does not.

DHelm templates do not support the <code>default</code> function.

Step-by-Step Solution

Solution:

Step 1: Understand default function behavior
The default function only applies if the value is missing or null, not if empty string.
Step 2: Analyze the empty string case
If image.tag is set but empty, default is ignored, resulting in empty output.
Final Answer:
The image.tag key exists but is set to an empty string, so default is ignored. -> Option A
Quick Check:
Empty string disables default function [OK]

Quick Trick: Default applies only if value missing or null, not empty string [OK]
