📝 WalkthroughWalkthroughThe compute-plane Helmfile now disables the OTel collector by default and derives its image repository from global image settings. Configuration, profile tests, documentation, and BDD scenarios validate the updated behavior. ChangesOTel collector defaults
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR makes optional collector startup opt-in and aligns its default image repository with global mirror settings, reducing the chance that telemetry blocks compute startup. Merge is reasonable with owner awareness that the README should document the supported explicit collector repository override.

Document the explicit image override in this section.
The example shows only enabled: true and global repository inheritance. Add global.nvcaOperator.selfManaged.otelCollector.imageRepository, or link to its existing documentation, so self-hosted users with a separate collector repository can use the supported override.
The PR objective states that explicit imageRepository overrides remain supported.

Why
The self-hosted compute profile implicitly enabled the NVCA OpenTelemetry collector whenever compute observability was enabled. That made a normal bootstrap depend on an optional collector image that is not published in every self-hosted repository. If the image was absent, telemetry prevented an otherwise valid compute plane from becoming healthy.
Environments that do publish the collector had a second problem: its repository did not inherit the global image registry/repository override, so an installation could mirror every required image correctly while this optional sidecar still pulled from another location.
Optional telemetry should not be an availability dependency. It should remain available through explicit opt-in and obey the same image-mirror settings as the rest of the stack.
What changed
<global.image.registry>/<global.image.repository>/nvcf-otel-collectorby default;For the Reviewer
Please focus on the distinction between enabling the BYO compute feature and explicitly enabling its collector, plus the repository-precedence assertions.
Validation

Coordination
This bootstrap reliability fix is independent of router authority/SNI behavior and can merge separately.
