Subject Re: Combination of image name and owner in AWS-EC2 AMI
Date Thu, 16 Jul 2015 15:10:15 GMT
Hi Yavor,

Within our jclouds integration code (in 
ComputeServiceRegistryImpl.findComputeService) we have:

    properties.setProperty(PROPERTY_EC2_AMI_QUERY,
    "owner-id="+conf.getStringKey("imageOwner")+";state=available;image-type=machine");

(It's a bit ugly having the code there; would be nicer if that were a 
first-class property on jclouds' AWSEC2TemplateOptions. That's an 
improvement we could make in jclouds).

You can thus specify imageOwner in your location's configuration, along 
with the imageNameRegex.

For example, in brooklyn.properties:

    brooklyn.location.named.mywindows1=aws-ec2:us-east-1
    brooklyn.location.named.mywindows1.imageOwner=801119661308
    brooklyn.location.named.mywindows1.imageNameRegex=Windows_Server-2012-R2_RTM-English-64Bit-Base-.*

    # And with wrong imageOwner
    brooklyn.location.named.mywindows2=aws-ec2:us-east-1
    brooklyn.location.named.mywindows2.imageOwner=1234567890
    brooklyn.location.named.mywindows2.imageNameRegex=Windows_Server-2012-R2_RTM-English-64Bit-Base-.*

Then try running:

     > brooklyn cloud-compute default-template --location mywindows1

    Location {
         provider: aws-ec2
         displayName: AWS Virginia
         identity: AKIAJB4XYEF3QZHA2NIA
         region: us-east-1
         Default template {
             Image: {id=us-east-1/ami-5b9e6b30, providerId=ami-5b9e6b30,
    name=Windows_Server-2012-R2_RTM-English-64Bit-Base-2015.06.10,
    location={scope=REGION, id=us-east-1, description=us-east-1,
    parent=aws-ec2, iso3166Codes=[US-VA]}, os={family=windows, arch=hvm,
    version=,
    description=amazon/Windows_Server-2012-R2_RTM-English-64Bit-Base-2015.06.10,
    is64Bit=true}, description=Microsoft Windows Server 2012 R2 RTM
    64-bit Locale English AMI provided by Amazon, version=2015.06.10,
    status=AVAILABLE[available], loginUser=root,
    userMetadata={owner=801119661308, rootDeviceType=ebs,
    virtualizationType=hvm, hypervisor=xen}}
             Hardware: {id=t2.micro, providerId=t2.micro,
    processors=[{cores=1.0, speed=0.1}], ram=1024,
    supportsImage=Predicates.and(requiresRootDeviceType(ebs),requiresVirtualizationType(hvm),Predicates.alwaysTrue(),Predicates.alwaysTrue())}
             Location: {scope=REGION, id=us-east-1,
    description=us-east-1, parent=aws-ec2, iso3166Codes=[US-VA]}
             Options: {userDataCksum=06fee983}
         }
    }

Whereas with the wrong imageOwner, it fails:

     > brooklyn cloud-compute default-template --location mywindows2

    ...
    java.lang.IllegalStateException: Unable to match required VM
    template constraints PortableTemplateBuilder[ports=[22],
    locationId=us-east-1,
    imageNameRegex=Windows_Server-2012-R2_RTM-English-64Bit-Base-.*,
    imageChooserFunction=brooklyn.location.jclouds.BrooklynImageChooser$ImageChooserFromOrdering@6f0bc1b6]

    Virginia:AKIAJB4XYEF3QZHA2NIA/aws-ec2:us-east-1@R26byq4u]; see list

    image matched predicate:
