Brooklyn support for ELB

Gives support for AWS's Elastic Load Balancer.

Note: this will likely be rolled into core https://github.com/brooklyncentral/brooklyn. However, it currently depends on the 10MB aws-sdk so this dependency has deliberately not been added to core brooklyn.

Build

To build, run mvn clean install.

Releases

Branch	Version	Apache Brooklyn version
0.1.x	0.1.0-SNAPSHOT	0.6.0
0.2.x	0.2.0-SNAPSHOT	0.7.0-incubating
0.3.x	0.3.0-SNAPSHOT	0.8.0-incubating
master	0.4.0-SNAPSHOT	0.9.0-SNAPSHOT

Example

First add the required jars to your Apache Brooklyn release (see "Future Work" for discussion of OSGi):

BROOKLYN_HOME=~/repos/apache/brooklyn/brooklyn-dist/dist/target/brooklyn-dist/brooklyn/
BROOKLYN_AWS_ELB_REPO=~/repos/cloudsoft/brooklyn-aws-elb
MAVEN_REPO=~/.m2/repository
AWS_SDK_VERSION=1.10.53
BROOKLYN_AWS_ELB_VERSION=0.4.0-SNAPSHOT

cp ${BROOKLYN_AWS_ELB_REPO}/target/brooklyn-aws-elb-${BROOKLYN_AWS_ELB_VERSION}.jar ${BROOKLYN_HOME}/lib/dropins/
cp ${MAVEN_REPO}/com/amazonaws/aws-java-sdk*/${AWS_SDK_VERSION}/*.jar ${BROOKLYN_HOME}/lib/dropins/

And launch Brooklyn:

${BROOKLYN_HOME}/bin/brooklyn launch

Then deploy an app. The example below creates an ELB, and cluter of Tomcat servers:

location: aws-ec2:us-east-1
services:
- type: brooklyn.entity.proxy.aws.ElbController
  name: ELB
  brooklyn.config:
    aws.elb.loadBalancerName: br-example-1
    aws.elb.availabilityZones: [us-east-1a, us-east-1b]
    aws.elb.loadBalancerProtocol: HTTP
    aws.elb.instancePort: 8080
    loadbalancer.serverpool: $brooklyn:entity("cluster")

- type: org.apache.brooklyn.entity.group.DynamicCluster
  id: cluster
  name: cluster
  brooklyn.config:
    initialSize: 1
    memberSpec:
      $brooklyn:entitySpec:
        type: org.apache.brooklyn.entity.webapp.tomcat.Tomcat8Server
        brooklyn.config:
          # points at maven-central 0.7.0-incubating/brooklyn-example-hello-world-webapp-0.7.0-incubating.war
          wars.root: https://bit.ly/brooklyn-0_7-helloworld-war
          http.port: 8080
  location: aws-ec2:us-east-1b

Future Work

This module should be built as an OSGi bundle, so that it can more easily be added to Brooklyn.
