Hi Richard,
Thanks for the reply. I looked at the advanced networking project and as you
mentioned, found it pretty daunting but will look again. My initial takeaway
about Brooklyn is that all of the entities seem to involve running instances. I
don't see any docs/examples showing more static infrastructure like an AWS VPC
or subnet or security group etc. Am I correct? I started creating some code
inheriting from BasicEntity (as opposed to SoftwareProcess since there's
nothing to SSH into for a VPC), but I don't quite understand the lifecycle of
how a BasicEntity derived object gets initialized.
Where would I put my code to create the VPC and later destroy it?
Would I still use "sensors" for example to return the VPC id provided by AWS?
My code thus far is attached.
awsVPC.java
==========
/**
* An {@link brooklyn.entity.Entity} that represents an ElasticSearch node
*/
@Catalog(name="AWS VPC", description="AWS VPC")
@ImplementedBy(awsVPCImpl.class)
public interface awsVPC extends BasicEntity {
@SetFromFlag("version")
ConfigKey<String> SUGGESTED_VERSION =
ConfigKeys.newConfigKeyWithDefault(SoftwareProcess.SUGGESTED_VERSION, "4.0.1");
@SetFromFlag("CidrBlock")
ConfigKey<String> CIDR_BLOCK = ConfigKeys.newStringConfigKey("CIDR_BLOCK",
"The CIDR block you want the VPC to cover. For example: '10.0.0.0/16'",
"10.0.0.0/16");
@SetFromFlag("EnableDnsSupport")
ConfigKey<Boolean> ENABLE_DNS_SUPPORT =
ConfigKeys.newBooleanConfigKey("ENABLE_DNS_SUPPORT", "Specifies whether DNS
resolution is supported for the VPC", true);
@SetFromFlag("EnableDnsHostnames")
ConfigKey<Boolean> ENABLE_DNS_HOSTNAMES =
ConfigKeys.newBooleanConfigKey("ENABLE_DNS_HOSTNAMES", "Specifies whether the
instances launched in the VPC get DNS hostnames.", false);
@SetFromFlag("InstanceTenancy")
ConfigKey<String> INSTANCE_TENANCY =
ConfigKeys.newStringConfigKey("INSTANCE_TENANCY", "The allowed tenancy of
instances launched into the VPC, default or dedicated", "default");
}
awsVPCImpl.java
=============
package com.siemens.cip.services.awsVPC;

Hi Scott,
Welcome to Brooklyn :-)
I suggest you take a look at the "advanced networking" project:
https://github.com/brooklyncentral/advanced-networking
It's a set of entities that support network concepts for a few clouds. It's not
strictly part of Brooklyn, instead it's part of the wider community.
AWS is not yet supported by advanced-networking, so your contribution could be
very useful! You could start by looking at how advanced-networking has done
this for CloudStack, and use similar techniques for your AWS VPC implementation.
Be warned that the networking is pretty complex code. If you are new to
Brooklyn and to Java I'd suggest starting with simpler entities first?
Richard.
