Hi Onder, on first look it seems that the KubernetesClusterServiceAutoConfiguration doesn't get injected with KubernetesClusterServiceConfiguration; i.e. here it is `null`[1].
Adding a starter might have caused a change in the order of bean initialization. I would create a JIRA issue for this, not sure if we should declare those `@Autowired` annotations with `required=true`, or perhaps create a constructor that takes those parameters to signify that they're required. There's also that `--debug`[2] parameter that you can specify that might give more clues... zoran [1] https://github.com/apache/camel/blob/49ef644fa5c7352c7757a41e9893d2d107002543/platforms/spring-boot/components-starter/camel-kubernetes-starter/src/main/java/org/apache/camel/component/kubernetes/springboot/cluster/KubernetesClusterServiceAutoConfiguration.java#L38-L39 [2] https://docs.spring.io/spring-boot/docs/2.1.8.RELEASE/reference/html/boot-features-spring-application.html#boot-features-startup-failure On Wed, Sep 11, 2019 at 5:37 PM Onder SEZGIN <ondersez...@gmail.com> wrote: > > Hi, > > i have a very similar usecase where i need to implement something very > similar what Nicola has written while ago. > > in my app, i have the very similar configuration and i also needed to > use camel-http-starter. > (of course there are bits and pieces but later on i narrowed down the error > that the issue is due to camel-http-starter) > > so simply in my final attempt, what i did to demo the problem was to > include the camel-http-starter to the original project where Nicola has > shared in this link. > > https://github.com/nicolaferraro/camel-leader-election > > so here is my clone with that small pom change to show the issue. > > https://github.com/onderson/camel-leader-election/commit/7d4afae97641c5ff703522e69f5ee152deb2f82f > > so while Nicola's example is perfectly fine, my example fails to start > failing and complaining about KubernetesClusterServiceAutoConfiguration > error as below. > > so is there any idea what might be causing this? > > 18:27:27.438 [restartedMain] ERROR o.s.boot.SpringApplication - | | > Application startup failed > > org.springframework.beans.factory.UnsatisfiedDependencyException: Error > creating bean with name 'cacheAutoConfigurationValidatorPostProcessor' > defined in class path resource > [org/apache/camel/component/http/springboot/HttpComponentSSLAutoConfiguration.class]: > Unsatisfied dependency expressed through method > 'cacheAutoConfigurationValidatorPostProcessor' parameter 0;
