Kubernetes - ConfigMaps

You wrote this volumeMount snippet but the ConfigMap files are not visible inside the container:

volumeMounts:
- name: config-volume
  mountPath: /etc/config
  readOnly: false

What is the error?

AmountPath must be /config, not /etc/config

BreadOnly should be true for ConfigMap mounts

CreadOnly is not a valid field in volumeMounts

DvolumeMount name does not match volume name

Step-by-Step Solution

Solution:

Step 1: Verify volume and volumeMount names match
The name field in volumeMounts must exactly match a volume name defined in the pod spec's volumes array. A mismatch results in an empty directory at the mountPath instead of ConfigMap files.
Step 2: Validate other fields
mountPath can be any path like /etc/config, readOnly: false is valid (though true recommended for ConfigMaps), and readOnly is a standard field.
Final Answer:
volumeMount name does not match volume name -> Option D
Quick Check:
volumeMount.name == volume.name required [OK]

Quick Trick: volumeMount name must match volume name [OK]
