Working with a customer last week we determined that Spring Boot applications using Liberty Buildpack failed to allow the "Auto-Scale" service to show up "Throughput" metrics and essentially mean we couldn't scale out or down application instances using Throughput metrics.https://console.ng.bluemix.net/docs/runtimes/liberty/index.html
It turns out the Agent within the IBM Liberty buildpack isn't quite picking up application WAR files created using Spring Boot and hence "Monitoring and Analytics
" and " (more...)

I almost always use the tomcat buildpack within IBM Bluemix for my Java based applications. By default IBM bluemix will use the IBM Liberty buildpack for java apps unless you specify otherwise. The buildpacks on Bluemix can be viewed using "cf buildpacks
" and the tomcat buildpack is referred to as "java_buildpack
So to use the tomcat buildpack in a manifest.yml you would target it as follows

We recently announced a seperate CLI for Bluemix known as "Bluemix CLI". You can find out more about it at the following link
The Bluemix command line interface (CLI) provides a set of commands that are grouped by namespace for users to interact with Bluemix. Some Bluemix CLI commands, which are called bx commands, are wrappers of existing cf commands, and others are unique for Bluemix. The information that follows (more...)

I rarely need to save state within the Servlet Context via an application scope, but recently I did and here is what your controller class would look like to get access to the ServletConext with Spring. I was using Spring Boot 1.3.2.RELEASE.
In short you implement the "org.springframework.web.context.ServletContextAware
" interface as shown below. In this example we retrieve an application scope attribute.
There is now a new command line plugin for IBM containers on Bluemix so you can push and run docker images using CF CLI itself. The steps below show you how to set this up and I use a basic spring boot application as a docker image to test this out.Steps
Take a note of the docker local host IP. In this example it was as follows, as I test my docker image on (more...)
I previously blogged about using the IBM Bluemix Secure Gateway Service as followshttp://theblasfrompas.blogspot.com.au/2015/11/ibm-bluemix-secure-gateway-service-step.html
I decided I would extend on this and Connect a Spring Boot Application to Oracle and consume Oracle data using the Secure Gateway Service.
The full demo is as followshttps://dl.dropboxusercontent.com/u/15829935/bluemix-docs/secure-gateway-oracle/index.html
I created this simple step by step guide on how to use the IBM Secure Gateway Service. Very simple demo which shows how easy it is to set this up and open a world of possibilities from on premise resources directly exposed via Bluemix whether it's PUBLIC or Dedicated/LOcal Instanceshttps://dl.dropboxusercontent.com/u/15829935/bluemix-docs/secure-gateway/index.html
The IBM Bluemix Dedicated/Local Administration Console also includes support for CLI to enable common management tasks to be performed using the Cloud Foundry Command Line by adding a plugin to enable support for it's commands.Note: The Bluemix Admin CLI plugin requires version 6.11.2 or later.Admin Console UIAdmin Console - Installing Command Line
The CLI to the admin console is installed as follows. The reference to this is found in your (more...)
I decided to take the Spring Security demo at the following link , and add Bootstrap to it. In the end it's basically the same code and the Form Based Login will accept one user "pas/welcome1
Here is the updated demo with Bootstrap added to the UI pages. You can deploy this to Bluemix using the "Deploy to Bluemix

I decided to take the Elasticsearch repositories as part of the Spring Data project a test drive. The Spring boot Elasticsearch repositories are described in the link below.http://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.repositories
In this example I create a basic Spring Boot application using Elasticsearch, Web, Rest Repositories along with Thymeleaf / Bootstrap as the view pages. The code for this is on GitHub which also provides the "Deploy to Bluemix
" button to deploy (more...)
I am more often then not using spring boot applications on IBM Bluemix and most of what I need is packaged with the application from JPA or JDBC, drivers, Rest etc. Of course with IBM Bluemix we can specify which build pack we wish to use but by default for java applications LIberty is used.
When a stand-alone application is deployed, a default Liberty configuration is provided for the application. The default configuration enables the (more...)
I recently posted about the "Deploy to Bluemix
" button which will automatically deploy an application into IBM Bluemix from a single click.http://theblasfrompas.blogspot.com.au/2015/09/adding-deploy-to-bluemix-button-to-my.html
If the application requires backing services they can automatically be created using the"declared-services" tag as shown below. Declared services are a manifest extension, which creates or looks for the required or optional services that are expected to be set up before the app is deployed, such (more...)
Not before time I finally added my first "Deploy to Bluemix
" button on my GitHub projects for Bluemix applications. The screen shot below shows this for the Spring Session - Spring Boot Portable Cloud Ready HTTP Session demo.
Here is what it looks like when I do deploy this using the "Deploy to Bluemix
" button and requires me to log in to IBM Bluemix. What happens when you use this button (more...)
The following guide shows how to use Spring Session to transparently leverage Redis to back a web application’s
when using Spring Boot.http://docs.spring.io/spring-session/docs/current/reference/html5/guides/boot.html
The demo below is a simple Spring Boot / Thymeleaf/ Bootstrap application to test Session replication using Spring Session - Spring Boot within IBM Bluemix. Same demo will run on Pivotal Cloud Foundry as well.
