I am trying to get a simple microservice to register to the Eureka Server and then have Zuul proxy to the microservice. I got the microservice to register to the Eureka Server. However, whenever I bring the Zuul service up I see that it is not registering to the Eureka Server. Whenever I try to route to the microservice I get the below exception:
Load balancer does not have available server for client: microservice
I am not able to figure out where the issue is. Any help would be greatly appreciated

Adding #EnableEurekaClient solved this issue. The Zuul application is now discoverable in the Eureka server and is able to route requests.
I had the correct annotation on my Zuul application #EnableZuulClient but still got that error.
The problem was that I started all the applications (Eureka, Zuul and the third application) at the same time instead of doing this one by one. So they all needed time to register. After some time, the error was gone and I could reach my service through Zuul client.
Wrong spring.application.name might be the reason for this error other than
adding #EnableEurekaClient to the Zuul application class.
I am trying to implement Turbine AMQP to actually consolidate all the hystrix.stream from multiple services into one and show it in hystrix dashboard.
Hystrix.stream from my service looks fine:-
Sample of what I am seeing in the stream from my client service:- localhost:4444/hystrix.stream

when I try to hit http://localhost:8989/turbine.stream it just says ping and this is what i see in the logs when i try to put the turbione.stream though it is not working in hystrix dashboard.

What is it that I am doing wrong here to get the turbine.stream to work.
my turbine knows about RabbitMQ but the client side service donot. Is there a need for me to tell the service also I know that turbine knows about all the hystrix.stream(s) from eureka so is turbine responsible to queue the hystrix.stream in Rabbit MQ.
Any help is appreciated I have been stuck in this for a while now and there are no good example that help.
My setup is spring boot cloud using netflix library
I managed to have Turbine aggregating Hystrix metrics from one service. However when I add more services I cant see them.
This is my setup (also uploaded this into github at:

What am i doing wrong? why I cant actually aggregate both services hystrix metrics(flight-integration service,coupon-service)
Thank you.
solved by #spencergibb suggestation. I added to each of the client the dependency of spring-boot-starter-amqp and created rabbitMQ broker. Turbine is aggregating all messages via amqp and I was able to see all Hystrix commands aggregated on my hystrix dashboard server
I understand that a Spring Cloud Config Server can be protected using an user name and password , which has to be provided by the accessing clients.
How can i prevent the clients from storing these user name and
password as clear text in the bootstrap.yml files in the client
application/services ?
The very basic "basic authentication" (from here https://github.com/spring-cloud-samples/configserver)
You can add HTTP Basic authentication by including an extra dependency on Spring Security (e.g. via spring-boot-starter-security). The user name is "user" and the password is printed on the console on startup (standard Spring Boot approach). If using maven (pom.xml):
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
If you want custom user/password pairs, you need indicate in server configuration file
security:
basic:
enabled: false
and add this minimal Class in your code (BasicSecurityConfiguration.java):
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
#Configuration
//#EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class BasicSecurityConfiguration extends WebSecurityConfigurerAdapter {
#Value("#{'${qa.admin.password:admin}'}") //property with default value
String admin_password;
#Value("#{'${qa.user.password:user}'}") //property with default value
String user_password;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password(user_password).roles("USER")
.and()
.withUser("admin").password(admin_password).roles("USER", "ACTUATOR");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.disable()
.httpBasic()
.and()
.authorizeRequests()
.antMatchers("/encrypt/**").authenticated()
.antMatchers("/decrypt/**").authenticated()
//.antMatchers("/admin/**").hasAuthority("ROLE_ACTUATOR")
//.antMatchers("/qa/**").permitAll()
;
}
}
#Value("#{'${qa.admin.password:admin}'}") allow passwords to be defined in property configuration file, environment variables or command line.
For example (application.yml):
server:
port: 8888
security:
basic:
enabled: false
qa:
admin:
password: adminadmin
user:
password: useruser
management:
port: 8888
context-path: /admin
logging:
level:
org.springframework.cloud: 'DEBUG'
spring:
cloud:
config:
server:
git:
ignoreLocalSshSettings: true
uri: ssh://git#gitlab.server.corp/repo/configuration.git
This works for me.
Edit: Instead of the Class, you can put basic user configuration directly in application.yaml:
security:
basic:
enabled: true
path: /**
ignored: /health**,/info**,/metrics**,/trace**
user:
name: admin
password: tupassword
For Spring Boot 2 the configuration in application.yml are now under spring.security.* (https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-application-properties.html#security-properties)
spring.security:
basic:
enabled: true
path: /**
ignored: /health**,/info**,/metrics**,/trace**
user:
name: admin
password: tupassword
Basic authentication configuration that works for me.
