Kubernetes - Helm Package Manager

You want to upgrade your Helm release webapp to version 3 of your chart but keep the previous configuration values intact except for changing the image tag to v3. Which command achieves this safely?

Ahelm upgrade webapp ./chart --reuse-values --set image.tag=v3

Bhelm upgrade webapp ./chart --reset-values --set image.tag=v3

Chelm upgrade webapp ./chart --set image.tag=v3

Dhelm rollback webapp 3 --set image.tag=v3

Step-by-Step Solution

Solution:

Step 1: Understand --reuse-values option
This option keeps existing values from the previous release and applies new overrides.
Step 2: Compare with other options
--reset-values resets to chart defaults, losing previous config. Omitting reuse-values loses previous config. Rollback does not upgrade.
Final Answer:
helm upgrade webapp ./chart --reuse-values --set image.tag=v3 -> Option A
Quick Check:
Use --reuse-values to keep old config and override selectively [OK]

Quick Trick: Use --reuse-values with --set to keep config and update specific values [OK]

Common Mistakes:

Using --reset-values and losing config
Not using --reuse-values and losing previous settings
Trying rollback to upgrade
