Spring Boot / Feign Client accessing external service

Previously we used Feign to create clients for our own services, which are registered on our Eureka Server using a service name as shown in the previous blog post http://theblasfrompas.blogspot.com.au/2016/11/declarative-rest-client-feign-with_8.html. It's not unusual that you'd want to implement an external rest endpoint, basically an endpoint that's not discoverable by Eureka. In that case, you can use the url property on the @FeignClient annotation,
which gracefully supports property injection. His an example (more...)

Deploying Spring Boot Applications on Google Application Engine (GAE)

I previously blogged about how to how to deploy a Spring Boot application to Flexible VM's on Google Cloud Platform as shown below.


In this example below I use Google Application Engine (GAE) to deploy a Spring Boot application without using a Felible VM which is alot faster and what I orginally wanted to get back to doing when I first did this previously. It short this is using the (more...)

Uploading Tiles into Pivotal Cloud Foundry Operations Manager from the Ops Manager VM directly

When deploying PCF, you start by deploying Ops Manager. This is basically a VM that you deploy into your IaaS system of choice and it orchestrates the PCF installation. The installation of PCF is done by you through a web interface that runs on the Ops Manager VM. Into that web interface, you can load various "tiles". Each tile provides a specific set of functionality.

For example, Ops Manager comes with a tile for Bosh (more...)

Installing Pivotal Cloud Foundry (PCF) on Google Cloud Platform (GCP)

I decided to install PCF 1.8 onto Google Cloud Platform today and I thought the experience was fantastic and very straight forward. The GCP Console is fantastic and very powerful indeed. The steps to install it are as follows


Here are some screen shots you would expect to see along the way when using Operations Manager

Accessing the Cloud Foundry REST API from SpringBoot

Accessing the Cloud Foundry REST API is simple enough to do as shown in the example below using curl we can list all our organizations.

Cloud Foundry REST API - https://apidocs.cloudfoundry.org/246/

Below shows just the organizations name and I am filtering on that using JQ, if you wnat to see all the output then remove the PIPE or JQ. You have to be logged in to use "cf oauth-token"

Declarative REST Client Feign with Spring Boot

Feign is a declarative web service client. It makes writing web service clients easier. To use Feign create an interface and annotate it. It has pluggable annotation support including Feign annotations and JAX-RS annotations. Feign also supports pluggable encoders and decoders.

In this example I show how to use Spring Cloud / Spring Boot application with Feign. The source code for this is as follows


1. Include the required maven dependency for Feign (more...)
