Is there a API to download PCF logs from PCF metrics? I don't like the way that PCF metrics present to me, I would like to use splunk or other tools to analyzing logs.
I could use download button in metrics but I it's too manual.
Any application running on Cloud Foundry can stream it's logs to any syslog comptabile service. Splunk has a syslog collector so you can follow the instructions here app log streaming Details for configuring this on PCF are at enter link description here

When deploying a set of SpringBoot microservice applications in a Kubernetes cluster, should I include any kind of service discovery client libraries in my SpringBoot application to leverage kubernetes-native-service-discovery? If not, how a caller service calls another microservice in the same cluster?
Thanks in advance.
A service in kubernetes can be invoked as mentioned below for example an http service. An service has to be created and associated with pod. Please refer kubernetes services documentation for various services.
http://<service-name>:<port>
No other changes are required from application end. Please refer kubernetes official documentation for resolution details
Hi I am looking on how to stream application logs from a Spring boot application to a cloud. To elaborate:- Suppose I have a spring app to be deployed as a pcf application for which I need to send the logs generated from the application to an external cloud platform.
You can configure appenders for loggers like logback, log4j2 to stream logs on external cloud platforms like aws cloudwatch with ease.
I'm using AWS lambda functions with spring boot and i able to see my all logs in AWS cloudwatch.
But now I want to get all those logs generated by my application.
Because I want to send those log files via mail.
I'm using Spring Boot 1.5.4 and Spring Cloud Dalston SR4 to stand up a Turbine server on Cloud Foundry and aggregate my application Hystrix streams. In addition I want to add Spring Boot Actuator monitoring and management to the Turbine server. I realize there is ample documentation on how to do this in a local environment and I do have it working locally. However it is a different matter when deploying to Cloud Foundry where I cannot use port numbers in a Url binding.
The issue is that the Turbine stream is provided by an RxNetty server on one port and the Actuator endpoints are provided by via Tomcat on another port. In Cloud Foundry I can only bind my Url to RxNetty endpoint or the Tomcat endpoint, not both.
No combination of management.port and turbine.stream.port allows me to access the turbine stream and the actuator endpoints from one host binding. The following is an example of what I would expect to be able to do:-
https://myapp.mydomain.com/info (to report actuator info details)
https://myapp.mydomain.com/turbine.stream (to stream turbine metrics)
Note: There are no port numbers in these Urls.
Requests to your app on Cloud Foundry go through the Cloud Foundry Go Router, which uses the http host header to direct traffic to all the container instances running your app. The http based gorouter expecter only one port to be opened by the app to forward http traffic to. However, the gorouter also support tcp routing which should allow you to have multiple ports open. see the docsfor an explanation of tcp vs. http routes on cloud foundry.
If you are running on Pivotal Cloud Foundry you can use the Circuit Breaker Dashboard provided by Spring Cloud Serviecs for PCF then you won't need to setup the turbine stream. The Spring Cloud Services Dashboard uses RabbitMQ instead of SSE events see SCS docs for details
Just getting back to this now. As noted by spencergibb, moving to springboot 2.0 and cloud Finchley works.
I am trying to build a Apache Ignite Cluster on Pivotal Cloud Foundry environment as follows.
Created a Spring-Boot app that starts a new Ignite node, Deployed it on on Cloud Foundry ( ex. Ignite-Node1)
Created another Spring-Boot app which will also starts a new Ignite node, Deployed it on on Cloud Foundry ( ex. Ignite-Node2)
Now, even though both the apps are running in a same CloudFoundry Env, they are not forming the Ignite Cluster as they are not able to discover each other.
Apache Ignite documentation provides examle configuration details for AWS, Google cloud , however there are no examples for Pivotal Cloud Foundry.
Can somebody provide me with an example configuration on how to get the Ignite Cluster running on Cloud Foundry environment.

Container-to-container (app-to-app) networking is not supported on Pivotal Cloud Foundry, although it is possible to enable.
By default all communications must be made 'via the front door' through Cloud Foundry's router, either via HTTP or on a TCP port. One cannot choose which instance of an application to hit. This is due to change with the Container Networking initiative, the progress of which you can check on Pivotal Tracker. There is a detailed design document which is publicly available.
An alternative approach which is more appropriate for data services is to deploy them using BOSH. As a PCF user, you may wish to consider creating a PCF Tile for Apache Ignite.
My company has been helping Hazelcast create a PCF Tile that will create dedicated-VM clusters on-demand. Perhaps you could consider making use of Hazelcast instead?
