Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Kustomize Controller
Flux's Source Controller fetches artifacts (e.g., Git repositories, Helm repos) but does not apply changes. The Kustomize Controller is the primary controller that reconciles the desired state from those sources to the cluster.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Image Automation Controller
Why it's wrong here
This controller automates image updates, not reconciliation of Git state.
- ✓
Kustomize Controller
Why this is correct
The Kustomize Controller watches for changes in Kustomize overlays and applies them to the cluster, ensuring the cluster matches the desired state.
- ✗
Source Controller
Why it's wrong here
The Source Controller manages the retrieval of source code and Helm charts, but does not apply them to the cluster.
- ✗
Helm Controller
Why it's wrong here
The Helm Controller manages Helm releases, but the question is about reconciling from a Git repository, which is typically done by the Kustomize Controller.
