Introduction

Training

Gave my Brooklyn training session to about 8 Waratek staff, from both development and QA backgrounds. Covered a wide range of topics, starting with a basic introduction to Brooklyn concepts and components, then moved up to policies and blueprints. Also included some waratek specific instruction on using the 'exotic' WaratekInfrastrcture entity and the associated WaratekLocation that is created dynamically.

We used YAML to create blueprints almost exclusively, rather than forcing people to write (or edit) Java code. Everyone deployed their applications to AWS EC2 (in Dublin, of course!) locations, rather than 'localhost', using a temporary IAM credential set I created. This all helped to reduce the number of problems with laptop setup significantly although there were still various idiosyncratic configuration issues to deal with. Many thanks to @ahgittin and @sjcorbett for their helpful suggestions here.

Of course, when I explained that the version of the

Changes to Startable Interface Static Fields

Recently the Startable#START field (public static final, by virtue of being part of a public interface) was modified. This caused problems when using applications linked against Brooklyn. In particular, if Brooklyn was built after the change without issuing an 'mvn clean' command then classes that merely referenced this static field did not get re-compiled, and their bytecode (including the old field value) was simply included in generated Jar files.

Migrating Complex Applications to Docker with Brooklyn

CFP

Abstract

Deploying enterprise-class distributed applications to docker containers spanning multiple hosts is tricky. Dealing with port forwarding, firewalls and injecting configuration into containers for inter-dependencies are just some of the problems.

We will show how Brooklyn's cloud abstractions can be used to simplify the deployment and management of a complex application to a virtual Docker infrastructure. Brooklyn will create and maintain the required Docker containers in the right locations for your application, and control and manage the software and services using policies to scale both the application and infrastructure based on their state.

Are there any examples of using the JMX agent? There doesn't seem to be any inside the brooklyn project, so I guess the users are hidden in some AMP-specific entities? [...] I'm trying to enable JMX-based sensors for Websphere Liberty Profile

The way I usually configure entities when I want to be sure that JMX works the way I expect, I set the JMXRMI agent and ports explicitly. In a Java application class, I do it when building an EntitySpec, setting the configuration in the init() method. This is from a Cassandra cluster application I was using at Waratek:

    @Override
    public void init() {
