> Key: CAMEL-20242
> URL: https://issues.apache.org/jira/browse/CAMEL-20242
> Project: Camel
> Issue Type: Improvement
> Components: camel-health, camel-microprofile-health
> Affects Versions: 4.1.0
> Reporter: Rinaldo Pitzer Júnior
> Assignee: Luca Burgazzoli
> Priority: Minor
> Fix For: 4.4.0
>
>
> The default status for the camel-routes health checks [is
> UP|https://github.com/apache/camel/blob/camel-4.1.x/components/camel-microprofile/camel-microprofile-health/src/main/java/org/apache/camel/microprofile/health/CamelMicroProfileRepositoryHealthCheck.java#L53],
> and it is used if none of the routes is reporting DOWN.
> When using the Supervising route controller, if the health check endpoint is
> called before the routes are started, the default status UP is reported.
> This means that the application reports as Ready even before the routes were
> attempted to be started.
> Even in scenarios where the route is certainly going to fail to startup,
> [like this
> one|https://github.com/rinaldodev/camel-playground/blob/7a30e964ba2ba233db347771d088b721cc331b82/src/main/java/com/github/lburgazzoli/MyRoutes.java],
> there is a brief period where the application reports as Ready.
> This brief period is long enough for Camel K to occasionally report an
> Integration as Ready before it really is, which also makes [some tests flaky
> | https://github.com/apache/camel-k/issues/4922].
> Possible solutions:
> # Don't report UP as the default camel-routes status: if the routes health
> check is enabled and there are no routes reporting yet, should this really
> default to UP?
> # Have a health check specifically check if the route controller is Ready: if
> routes weren't even attempted to be started, then the supervising route
> controller could report itself as DOWN.
> # ?
