Estou executando vários microsserviços no Kubernetes e preciso saber o IP real do cliente que enviou a solicitação ao nosso microsserviço de gateway para mostrar isso no painel da interface do usuário. Eu uso o Flannel como minha rede de sobreposição dentro do meu cluster.
Eu instalei o SonarQube versão 7.9.1 no CentOS 7 e o serviço configurado para iniciar com o usuário não root. O meu vm.max_map_countestá definido como 262144.
sysctl vm.max_map_count
vm.max_map_count = 262144
Por causa da versão do My SonarQube, configurei o JDK Wrapper.confpara
wrapper.java.command=/usr/lib/jvm/java-11-openjdk/bin/java
Meu sonar.log é:

Instalei o ApacheDS no CentOS 7, mas ele não inicia quando o sistema inicializa e devo iniciá-lo manualmente, o que devo fazer?
Instalei o SonarQube no CentOS e o serviço Sonar está ativo e em execução. No arquivo de configuração, a porta de uso está definida como 9000. Mas a interface do usuário do Sonar não pode ser acessada em localhost:9000.
Este é o meu sonar.log:
