Does it make sense to take advantage of netflix oss components(zuul, eureka, etc) from rails api microservices deployed in heroku?
What is the right way to deploy both a rails app and a spring cloud sidecar in heroku. same dyno? single web process? Also, what is the recommended approach for a centralized/dynamic configuration in heroku. spring cloud config, archaius, etcd?

I am going to create a kubernetes cluster to deploy all my spring boot microservices. Currently I have a spring cloud gateway server, a eureka discovery server and my back-end and front-end applications.
Do we need gateway server and discovery server if deployed on kubernetes, as these services are provided as part of cluster?
Thanks.
You are not required to use the Spring Cloud Gateway or Eureka discovery server. Kubernetes provides all basic building blocks (like Service) implemented without additional software requirements (for example with plain DNS).
If you need a more advanced setup you can integrate kubernetes API in Spring applications or use other ways to integrate. For the 90% case there is no need to do so.
Developing microservices using Spring Boot, and are currently working on containerizing our applications. However, I can't seem to figure out best practices for Cloud Config client.
How do I best update the cloud config server for the docker container?
Thanks!
In practice, the your containerized config application should be pulling the config from some centralized repository where configs are checked in and from there your microservices or containerized app will pull the config for further process.
We want to integrate legacy grails 2.4 and java7 application to our microservices infrastructure. We use spring cloud netflix, Camden.SR4 release and java8 in microservices setup. We use zuul, eureka, config service.
I know that with grails 3 this task is relatively easy, but currently we cant do that.
The biggest question is how can I register grails 2.4 app in Eureka.
Also, we don't want to use sidecar at the moment.
Spring Cloud requires Spring Boot. There's nothing keeping you from using the netflix eureka libraries directly.

I am trying to learn and create a microservice using Spring Cloud. I am using Spring mvc and Spring Boot for development. I added separate Spring Boot application for both Eureka server and Zuul client. I have three Spring Boot application now. One Sureka server, one for Zuul routing and third one is for my microservice application. I run the Eureka server and the microservice and Zuul found to be running properly in Eureka server UI.
My doubt is that, I am planned to use routing and service discovery in my microservice. So I have a total of three Spring Boot applications. Can I deploy these three applications into AWS Elastic Beanstalk?
When I exploring I found that Pivotal Cloud Foundry topic. Since I am planing to use AWS Elastic Beanstalk. So what is the role of Pivotal Cloud Foundry in my application?
I am still confused about microservice development using Spring Cloud.
So there are two elements in your confusion. Is Amazon Beanstalk suitable?
So answer is yes. but you have overhead of orchestrating various services of amazon over then. Basically Amazon Elastic Beanstalk is more form based which means you need to tell what exactly you want to do with application for example route setup , scaling mechanism , application portability, application health management , Integration with external log aggregators etc. This is big learning curve to many people (including me :) ). Where as these with PCF these things are easy and straightforward and sometimes implicitly done.
Now Can I use pivotal cloud foundry with amazon? answer will be absolutely yes.
Pivotal cloud foundry is Wrapper written over open source Cloud Foundry project.
It is more succinct PaaS option than Amazon Beanstalk. You can host PCF on amazon ec2 ( IaaS )boxes using BOSH software. To answer you PCF is a alternative to Amazon Beanstalk. You don't need PCF is you want to use Amazon Beanstalk and vice versa.
I have a UI application built using Angular , Bootstrap and HTML5 which interacts with number of backend services. In order to deploy this application in PCF , should this be converted to a Spring Boot app? Or is there a way to use any of available buildpacks to deploy this UI app in PCF?
In case there is no need to deploy backend services, I would go with the cloudfoundry static buildpack.
http://docs.cloudfoundry.org/buildpacks/staticfile/index.html
Otherwise you will need to decide how you are going to deploy the backend services for this application. There are a number of buildpacks available that could be used for deploying the backend services and delivering the frontend content within the same app (one of them being, as you mentioned the java buildpack that can be used to deploy a spring boot app). Here is a list of available buildpacks:

Its not needed to convert your application to spring boot, but doing so will definitely make life easier for you, trust me. Once u convert ur app to a spring boot right, you can remote debug ur application by jst running ur app as a spring boot app.
