Kubernetes - Helm Package Manager

You run helm install myapp bitnami/nginx --set replicas=3 but the pods remain at 1 replica. What is the likely cause?

AThe Kubernetes cluster is out of resources

BThe chart does not support the replicas parameter

CYou forgot to run 'helm repo update' before install

DThe --set flag syntax is incorrect

Step-by-Step Solution

Solution:

Step 1: Understand Helm parameter overrides
If the chart does not define the parameter replicas, setting it has no effect.
Step 2: Analyze other options
Resource shortage or repo update issues would cause different errors; syntax is correct.
Final Answer:
The chart does not support the replicas parameter -> Option B
Quick Check:
Unsupported parameter = no effect on deployment [OK]

Quick Trick: Check chart values.yaml for supported parameters before setting [OK]
