Error init SpringBoot 2.1.8.RELEASE using actuator - spring-boot

I have a SpringBoot 2.1.8.RELEASE, but when I start the app. I got this error:
2019-10-01 10:38:24.373 ERROR 16232 --- [ main] d.c.b.a.s.c.d.InstanceDiscoveryListener : Couldn't register instance for discovered instance...

and I have this properties defined in my yml file
server:
port: 2222
servlet:
contextPath:

Just remove
servlet:
contextPath:
and try hitting your API.
If you want default path of the application then
servlet:
contextPath: /api
Then your API looks like :
http://127.0.0.1:2222/api/actuator/health

Change the yml file as below and try:
server:

servlet.context-path: /

Spring API Gateway java.net.ConnectException: Connection timed out: no further information

I have a spring boot app with simple GET method "sayHello" i have configured API gateway to route calls to my microservice module when uri pattern matches /ms1/**

I am getting following error when i access via gateway, however when i access my microservice directly it works any idea where i am wrong here?
http://localhost:8010/ms1/sayHello <- Not working via gateway

I have faced the same issue today as well when running the micro services, the gateway and the Eureka discovery all on localhost.
I was able to solve it by adding eureka.instance.preferIpAddress=true to my application.properties of the micro services. That property causes that the services will advertise their IP addresses instead of the host names. More info here under point 2.6: https://cloud.spring.io/spring-cloud-netflix/multi/multi_spring-cloud-eureka-server.html. My guess is that there was an issue with forwarding the requests to the microservices due to using localhost.
Edit: Here are my settings
There is nothing special in my setup. These are the values I am using in my application.properties
The microservice is using:
spring.cloud.discovery.enabled=true
spring.application.name=[The name of my app]
eureka.client.register.with-eureka=true
eureka.client.service-url.defaultZone=http://localhost:8999/eureka
eureka.instance.prefer-ip-address=true
The properties for the gateway are similar to the service one.
The load balancing part looks like this:
spring.cloud.gateway.routes[0].id=[Same name as my app]
spring.cloud.gateway.routes[0].uri=lb://[name of my app]
spring.cloud.gateway.routes[0].predicates=Path=/test/**
Where test/** is the part of the Rest URL of my application
Adding DESKTOP-1.verizon.net to hosts file worked, following is entry I have added to C:\Windows\System32\drivers\etc\hosts file. Unfortunately eureka.instance.prefer-ip-address=true didn't work for me
127.0.0.1 DESKTOP-1.verizon.net
have added this settings in yml file in all services and its work for me.
eureka:
instance:
prefer-ip-address: true
I just faced the same issue, and in my case, I had a problem with port number. I was using the code below to set up the port for me:
server:
port: ${random.int(8010,8013)}
I noticed when the service starts, even though the log shows "Tomcat started on port(s): 8010", on Eureka's page shows "host.docker.internal:my-service:8011"
This error happens randomly, because sometimes when you re-start the microservice, it is able to register on Eureka correctly.
You can do a simple test using a non-random port number.
I haven't figured out how to solve it for random port number.
UPDATING:
I did this and worked fine for me:
server:
port: 0
spring:
application:
name: user-service
eureka:
instance:
hostname: localhost
prefer-ip-address: true
client:
serviceUrl:
defaultZone: http://localhost:9000/eureka/

Is there limitation on port 8888?
why my client starts with looking for 8888

If I use 8888 in config server, then client works cleanly, without exception.
What is 8888 magic and why I have to stick to it? Is this boot version issue or my mistake?
Resolved -
Changed cloud client project application.yml filename to bootstrap.yml
port 9000 of server works
bootstrap.yml gets loaded before application.yml
Very important, the client application name needs to be the same as the properties name in the repository.For example,your config client application name is config-client,then your properties file in your repository should be config-client-dev.properties.Or you will get the Could not resolve placeholder ${xxx} error.
Add the below dependency in your pom.xml file
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

For example, your config client application name is config-client, then your properties file in your repository should be config-client-dev.properties. Or you will get the "Could not resolve placeholder ${xxx}" error.
Spring cloud server that uses git as a property source works with the repository in git style, so it can use different branches, and what`s important regarding the question - the changes must be committed for being visible.

Eureka server and eureka client to separate tomcat servers

I'm looking for a way to be able to deploy the Eureka server to a different tomcat server than the Eureka client.
this is the client application.yml:
eureka:
client:
registryFetchIntervalSeconds: 5
instance:
preferIpAddress: true
leaseRenewalIntervalInSeconds: 10
server:
port: 8080
spring:
application.name: my-client
jmx:
default-domain: my-client
and the server application.yml looks like:
server:
port: 8761
eureka:
client:
registerWithEureka: false
fetchRegistry: false
It works perfectly fine if I deploy them to the same tomcat-server. But if I start the tomcat with the server only and later start the server with the client, I get the following error:
2017-03-09 16:17:58.496 INFO 7693 --- [on(2)-127.0.0.1] com.netflix.discovery.DiscoveryClient : Registered Applications size is zero : true

What is the difference between bootstrap.yml and application.yml?
Any help would be appreciated!
your client application.yml dosen't have information about where your eureka server is running.client should register with eureka server, for that you need to configure your client application.yml as follow
eureka:
client:
serviceUrl:
defaultZone:http:localhost:8081/eureka/
instance:
instanceId:application_name:${random.value}

Error starting jHipster Microservices with consul

I'm trying to build sample microservice app using this tutorial.
Jhipster version is 4.0.6
So i've created gateway, service and started consul using this command:
docker-compose -f src/main/docker/consul.yml up
from my gateway directory.
But the error occur on Spring Boot startup, here is the log:
2017-02-22 11:52:25.679 ERROR 3168 --- [ restartedMain] o.s.c.c.c.ConsulPropertySourceLocator : Fail fast is set and there was an error reading configuration from consul.

com.ecwid.consul.transport.TransportException: java.net.ConnectException: Connection refused: connect
Could you please assist with this issue?
UPDATE:
I've found that app tries to make GET request to URL on staptup:
http://localhost:8500/v1/kv/config/armory,dev/?recurse&token=
But the only data stored in Consul K/V storage is:
KEY: config/application/data
VALUE:
configserver:
name: Docker Consul Service
status: Connected to Consul Server running in Docker
jhipster:
security:
authentication:
jwt:
secret: my-secret-token-to-change-in-production
You must copy your application yaml configurations into your consul instance as explained in the doc into central-server-config directory if consul is running in dev profile or in its git repo if consul is running in prod profile.
So assuming your app is named "armory" you should copy your src/main/resources/config/application.yml to armory.yml and for each profiles (e.g. application-dev.yml to armory-dev.yml)

Zuul -> Eureka Server, Basic Authentication issue

I am able to hit the service, if the flow doesn't contain Basic Authorization.
If i use Basic Authorization, it throws "message": "Full authentication is required to access this resource"
Below are my observations:
In ZuulFilter, run() method, i get value for
request.getHeader("Authorization") --> Basic c29tOnNvbzz==
but once it reaches the Micro Service, i am getting value as 'null',
request.getHeader("Authorization") --> null
Using Spring Boot version : 1.4.0.RELEASE
This is my flow:
------------------
Zuul -> Service Discovery (Eureka Server) -> Service
Kindly help, not sure where the Authorization header is vanishing.

Authorization is by default a sensitive header, this means Zuul will not forward them. If you leave it out of the sensitive headers, Zuul will forward the header.
zuul.sensitiveHeaders: Cookie,Set-Cookie
It should also be camelCase instead of hyphenated.
Extra info: https://github.com/spring-cloud/spring-cloud-netflix/blob/master/docs/src/main/asciidoc/spring-cloud-netflix.adoc#cookies-and-sensitive-headers
This solved my problem, but is this the only solution we have ?
ctx.addZuulRequestHeader("Authorization",request.getHeader("‌​Authorization"))
Your property for zuul.sensitiveHeaders is wrong. It is camel case not hyphenated.
