Embedded MongoDB not starting while running spring boot application

I have created a sample spring application that has mongoDB dependency added in pom.xml. I haven't added any code apart from the dependencies but I get the following error when I try running it. I have tried multiple approaches and workaround but I still see the same error.

Spring Cloud Kubernetes application does not detect when it is running in a pod

Expected Behavior
According to the Spring Cloud Kubernetes documentation, all that is necessary for a Spring application to detect when it's running in a pod is to add Spring Cloud Kubernetes to the classpath with the spring-cloud-kubernetes-all dependency.
This triggers two events:
If present the application-kubernetes.yml profile is loaded.
The Kubernetes implementation of DiscoveryClient is used for service discovery, leveraging KubeDNS instead of the default of Eureka.
This environment awareness is described here:
https://cloud.spring.io/spring-cloud-static/spring-cloud-kubernetes/1.1.0.RELEASE/reference/html/#kubernetes-profile-autoconfiguration
and here:
https://cloud.spring.io/spring-cloud-static/spring-cloud-kubernetes/1.1.0.RELEASE/reference/html/#discoveryclient-for-kubernetes
Actual Behavior
After booting the Spring Cloud Kubernetes application using the following yaml and accessing it's actuator endpoint at http://minikube-ip:port/actuator/env via a NodePort, I see there are no active profiles set, even though a application-kubernetes.yml exists in the resources folder:
{
"activeProfiles": [],
...
Upon further investigation in the http://minikube-ip:port/actuator/info endpoint, I see that the Spring application isn't aware it's in a pod at all, as evidenced by:
{
"kubernetes": {
"inside": false
}
}

Any help would be greatly appreciated! Thank you!

Are you sure you should have spring.cloud.kubernetes.enabled=false in your application.yml? If I understand the docs correctly, you need to leave it to the default value (true) in order for it to do the detection and load the kubernetes profile.
If you disable it, it will never load your application-kubernetes.yaml, so setting it to true inside that file will have no effect.
As I understand it you can turn off kubernetes features (e.g. spring.cloud.kubernetes.config.enabled=false) in your main YAML, but not the entire k8s integration if you want profile autoconfiguration to work.

Here is the application.yml, application-kubernetes.yml, and build.gradle combo that finally worked for me:

The issue I see is, it is trying to connect some localhost whereas I have my addon CloudAMQP
Little Lemur added in heroku and I have added these to my both Application.yml file:
spring:

rabbitmq:

In my webModule I have this code:
#SpringBootApplication
public class SpringBootHerokuExampleApplication {
public final static String PDF_MERGE_QUEUE= "pdf-merge-queue";
#Bean
Queue queue(){
return new Queue(PDF_MERGE_QUEUE, false);
}
#Bean

#Bean

#Bean

container.setConnectionFactory(connectionFactory);
container.setQueueNames(PDF_MERGE_QUEUE);
container.setMessageListener(listenerAdapter);
return container;
}
#Bean

return new MessageListenerAdapter(rabbitMQListener, "receiveMessage");
}
public static void main(String[] args) {
SpringApplication.run(SpringBootHerokuExampleApplication.class, args);
}
}
and in my worker module main method:
public class SpringBootHerokuExampleApplication {
public final static String PDF_MERGE_QUEUE= "pdf-merge-queue";
public static void main(String[] args) {
SpringApplication.run(SpringBootHerokuExampleApplication.class, args);
}
}

Why is it trying to connect to localhost when I have specified host name explicitly in yml file? Any Idea?

Just found out that in yml file I have a profile named as heroku, when I removed it , it connected to the RabbitMQ in the given host.

If you are using spring boot you can configure Rabbit by spring cloud stream.
In this case you dont have to configure the beans and the configuration is much easier:
spring:
#---------------- RabbitMQ -----------------#
rabbitmq:
#Default username ans pass
dynamic: true
host: localhost
port: 5672
username: guest
password: guest
#---------------------------- RabbitMQ properties Commons ------------------------------#
cloud:
stream:
bindings:
springCloudBusInput:
destination: InputExchange
group: Queue
producer:
exchangeAutoDelete: false
springCloudBusOutput:
destination: InputExchange
group: Queue
consumer:
exchangeAutoDelete: false
Then you have to create the listener:
#Component
public class RemoteEventListener implements ApplicationListener<InputEvent> {
#Override
public void onApplicationEvent(InputEvent inputEvent) {
//whatever you want to do when a InputEvent Type is received in the queue
}
}
In this case My app is writing and receiving from the same exchange
and queue (Because of testing so stuff)
If you want to configure rabbit the way you shown, try to create a configuration class with the beans of the queue, exchange and biding with #Configuration. Dont declare the beans in your app class.
It seems it can not read the autodelete property of the queue, but if I'm not wrong I should take the default.
Maybe You have network issues
Check the rabbitmq and restart it
Can you acces to rabbitMq administrator interface?
About the comment about whi is trying to connect with localhost add this to your bean definition:
#Autowired
private ConnectionFactory rabbitConnectionFactory
#Bean
public RabbitTemplate rubeExchangeTemplate() {
RabbitTemplate r = new RabbitTemplate(rabbitConnectionFactory);
r.setExchange("rmq.rube.exchange");
r.setRoutingKey("rube.key");
r.setConnectionFactory(rabbitConnectionFactory);
return r;
}
also remove addresses of your application.yml

Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/diviso/dev/master": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused
This warning message means that your application could not connect to its spring cloud config server: JHipster Registry.
In dev profile, this is just a warning that you can ignore as your application can run with local application properties in sc/main/resources/config.
In prod profile, this would be an error and your application would not start. The registry must be started before your app because this is where your app gets its application properties from and registers itself as an Eureka client.
So in dev, you can ignore this warning or if it annoys you, you can start a registry.
If your app is a monolith application and not a microservice application, you can opt out the discovery client question, it'll be simpler to deploy if you don't need horizontal scaling.

The same issue happened with me, although I have already generated and modified my project before.
In case you are using MySql, go to phpMyAdmin page and type in your credentials. Worked for me.

Embedded Tomcat won't listen to port 80 in AWS Elastic Beanstalk

I'm launching a Spring Boot .jar with Embedded Tomcat to an Elastic Beanstalk (Java) instance.
server.port=80 in the configuration file, however EB won't let Tomcat bind to port 80.
What's preventing Tomcat from listening to port 80 and how do I fix it?
Here's the pertinent section of the logs:

Description:
The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 80, or configure this application to listen on another port.

I assume topic starter already resolved this problem, but I'll post my solution here for the new people who'll be stuck on the same issue.
I've made my Spring Boot application accessible from port 80 on AWS Elastic Beanstalk by setting environment property SERVER_PORT to 5000 (you can set it in "Configuration" > "Software Configuration").
