Ignasi Barrera updated JCLOUDS-1350:
    Component/s: jclouds-compute

> AWS EC2 mis-detecting OS version of image
> -----------------------------------------
>                 Key: JCLOUDS-1350
>                 URL: https://issues.apache.org/jira/browse/JCLOUDS-1350
>             Project: jclouds
>          Issue Type: Bug
>          Components: jclouds-compute
>    Affects Versions: 2.0.2
>            Reporter: Richard Downer
>            Priority: Minor
> I have an image in my AWS EC2 account with this metadata:
> Image [architecture=X86_64, description=null, ebsBlockDevices={/dev/sda1=EbsBlockDevice
[deleteOnTermination=false, snapshotId=snap-0f1dbc42eb5353012, volumeSize=8, volumeType=null,
iops=null, encrypted=false]}, imageId=ami-dc667dba, imageLocation=449550055360/CentOS 7 x86_64
repacked by Richard, imageOwnerId=449550055360, imageState=available, imageType=MACHINE, isPublic=false,
kernelId=null, name=CentOS 7 x86_64 repacked by Richard, platform=null, productCodes=[aw0evgkw8e5c1q413zgy5pjce],
ramdiskId=null, region=eu-west-1, rootDeviceName=/dev/sda1, rootDeviceType=ebs, virtualizationType=hvm,
hypervisor=xen, tags={group=random}]
> jclouds is detecting this as version 5, not version 7.
> The reason for this appears to be {{ComputeServiceUtils.parseVersionOrReturnEmptyString}}.
This is being invoked from {{EC2ImageParser}} with the argument {{449550055360/CentOS 7 x86_64
repacked by Richard}}. This function searches for a number that might be a version, and if
it finds it, applies it to the OS metadata builder.
> In this case, it is matching one of the {{5}} digits and thinking that my image is CentOS
> EC2ImageParser is providing {{imageLocation}} as the method's argument, which is a combination
of the owning account ID and the name. A simple solution to this problem might be to use the
{{name}} field instead.
> However I wonder if the {{parseVersionOrReturnEmptyString}} method should be a bit smarter
and not attempt to use a number if it appears in the middle of a group of numbers.
