This project is obselete and no longer maintained.

Spring Cloud Lattice

Preview of Spring Cloud Lattice implementation

Setup

Tested with lattice v0.5.0

Create redis, rabbit and mysql using the lattice docs.

mysql -h"192.168.11.11" -p"somesecret" -u"root"
CREATE DATABASE test;

Running the sample

Install lattice
Follow the getting started guide, including scaling lattice-app to 3
run mvn --settings .settings.xml install
run PROCESS_GUID=spring-cloud-lattice-sample java -jar spring-cloud-lattice-sample/target/spring-cloud-lattice-sample-1.0.0.BUILD-SNAPSHOT.jar
visit http://localhost:8080?service=lattice-app verify that the 3 services rotate through as you refresh

Running the sample ON LATTICE

./mvnw clean package
ltc build-droplet sc-lattice-sample java --path=spring-cloud-lattice-sample/target/spring-cloud-lattice-sample-1.0.0.BUILD-SNAPSHOT.jar
ltc launch-droplet sc-lattice-sample sc-lattice-sample
visit http://spring-cloud-lattice-sample.192.168.11.11.xip.io?service=sc-lattice-sample verify that the 3 services rotate through as you refresh
visit http://sc-lattice-sample.192.168.11.11.xip.io/me verify that the 3 services rotate through as you refresh

IDE Discovery

if you run SampleLatticeApplication in the IDE on port 8081 you can run it on lattice with the following command

LATTICE_CLI_TIMEOUT=180 ltc create spring-cloud-lattice-sample spencergibb/spring-cloud-lattice-sample -- java -jar /spring-cloud-lattice-sample.jar --spring.cloud.lattice.discovery.routes.myservice.port=8081

Then call http://spring-cloud-lattice-sample.192.168.11.11.xip.io/call and it will hit the service running in the ide.

Config Server

spring-cloud-lattice's Issues

Configserver on lattice should be found via discovery

because lattice provides the discovery it doesn't make a ton of sense to run configserver first to find discovery.

rename to spring-cloud-diego

Since diego is what we are really targeting here.

Add lattice to active profiles if running in lattice

@mstine do you think this is worth it, or just let the user add an environment variable?

Developer integration workflow

Allow a developer to run a service on the host (ie laptop) and have the services in lattice be able to hit the in IDE (or java -jared) app on the host. The host service is visible to lattice via 192.168.11.1 which is the virtualbox gateway. Not sure about other vagrant providers (vmware).

spring:
  cloud:
    lattice:
      - myService:
          host: 192.168.11.1 #could skip as this is the default
          port: 8765

Change version to 1.0.0

We haven't had a 1.0.0 so 1.1.0 is wrong.

Error creating bean with name 'ribbonLoadBalancer'

I get the following error when executing the sample on a local lattice runtime (based on Vagrant/VirtualBox on Mac OSX)

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
Error creating bean with name 'ribbonRestClient' defined in org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration: Unsatisfied dependency expressed through constructor argument with index 1 of type [com.netflix.loadbalancer.ILoadBalancer]: : Error creating bean with name 'ribbonLoadBalancer' defined in org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.loadbalancer.ILoadBalancer]: Factory method 'ribbonLoadBalancer' threw exception; nested exception is org.springframework.web.client.HttpClientErrorException: 404 Not Found; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ribbonLoadBalancer' defined in org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.loadbalancer.ILoadBalancer]: Factory method 'ribbonLoadBalancer' threw exception; nested exception is org.springframework.web.client.HttpClientErrorException: 404 Not Found

Any ideas?
