Summary

Consuming apps that still expose Spring Boot Actuator's own info endpoint (management.endpoints.web.exposure.include containing info or *) would get a conflicting handler for GET /info the next time they pick up a newer nv-boot pin, since InfoConfiguration (added in #1671) previously registered InfoController unconditionally.

Makes the shared /info endpoint opt-in via nv-boot.info.enabled: true, defaulting to off. Existing consumers need zero changes to keep their current behavior; services that want the shared endpoint (nvcf-service, nvct-service, notary-service, spot) need nv-boot.info.enabled: true added to their own bootstrap.yaml.

InfoController repeats the @ConditionalOnProperty directly (not just on InfoConfiguration), since @RestController makes it classpath-scannable independently of that configuration class's own condition — without this, a consuming app's component scan would still construct it even when opted out, failing to find its now-conditionally-absent InfoResponseService dependency.

Testing

  • bazel test //src/libraries/java/nv-boot-parent/nv-boot-starter-core:tests passes (58/58, including the pre-existing integration tests this uncovered a real gap in).
  • Verified end-to-end against ess-api-service: pointed its nvcf pin at this branch with its existing (unmodified) config, confirmed the app starts cleanly, GET /info still returns Actuator's own nested shape, and GET /health is unaffected.

Summary by CodeRabbit

  • Configuration
    • The /info endpoint is available only when explicitly enabled. Several services now enable it in their configuration.
    • When the setting is absent or set to false, the endpoint is not available and requests to /info return a 404 response.
    • When enabled, /info provides service information, including the service name, version, and commit details when available.

Consuming apps that still expose Spring Boot Actuator's own info
endpoint (management.endpoints.web.exposure.include containing
"info" or "*") get a conflicting handler for GET /info the next time
they pick up a newer nv-boot pin, since InfoConfiguration previously
registered unconditionally.

Add OnActuatorInfoNotExposedCondition, a custom Condition that
inspects that property directly (Actuator's own info endpoint is
registered dynamically, not as a discoverable bean, so
@ConditionalOnMissingBean can't detect it). This lets existing
consumers (e.g. ess-api-service) upgrade nv-boot with zero changes,
and lets them adopt the shared endpoint later just by dropping
"info" from that exposure list in whichever profile should use it.

📝 Walkthrough

Walkthrough

The info configuration and controller now activate only when nv-boot.info.enabled equals "true". Five service bootstrap files set this property to true. Integration tests cover enabled, disabled, and absent-property cases.

exclude precedence over include. Add tests covering exclude=info and
management.endpoint.info.enabled=false, confirming the starter’s info handler

InfoConfiguration only when Actuator’s effective GET /info route is served on
the application server; do not rely solely on whether the exposure include
property contains info. Account for management.server.port when determining the

/info separately.

Simpler than inferring from Actuator's exposure config: the shared
/info endpoint now only activates when nv-boot.info.enabled=true is
set explicitly. Defaults to off, so it never conflicts with an
existing /info handler in a consuming app.

InfoController repeats the condition directly (not just on
InfoConfiguration), since @RestController makes it classpath-scannable
independently of that configuration class's own condition -- without
this, a consuming app's component scan would still construct it even
when opted out, failing to find its now-conditionally-absent
InfoResponseService dependency. This is what broke
NvBootCoreIntegrationTest/NvBootCoreReactiveIntegrationTest until
fixed.

Consumers that want the endpoint (nvcf-service, nvct-service,
notary-service, spot) need nv-boot.info.enabled: true added to their
own bootstrap.yaml in a follow-up change.

…fo tests

nvcf-service, nvct-service, icms-service, and notary-service each
already have an infoEndpointReturnsOk()-style integration test from
#1671 that asserts GET /info returns 200. Since InfoConfiguration is
now opt-in (default off), those tests started failing CI. Set
nv-boot.info.enabled: true in each service's own bootstrap.yaml so
the endpoint stays enabled for these existing consumers.

Verified locally: bazel test on all four
:tests_coverage targets now passes.

@shelleyshen-0 a few suggestions:

  1. Can you add the nv-boot.info.enabled: true to API Keys’ bootstrap.yaml as well?
  2. Could you add Spring-context tests for the flag being absent, false, and true, including component scanning?
  3. Minor one: Update description on services needing a follow-up change, since this PR already has it for most of the services.

Adds nv-boot.info.enabled: true to api-keys' bootstrap.yaml (missed
in the earlier pass covering nvcf-service, nvct-service, icms-service,
and notary-service).

Adds 3 Spring-context integration tests covering the flag absent,
explicitly false, and true, reusing TestApplication (which does real
classpath component scanning of com.nvidia.boot.core.info, the same
mechanism that caused the earlier InfoResponseService bean-not-found
bug) rather than ApplicationContextRunner, since the latter doesn't
exercise component scanning.
