Source instance name change for Openstack builder

[Chris Stone]

Hello. Is it possible to change the name of the temporary Openstack instance that gets built during the Packer build process? For the AWS builder, it allows you to set tags and if you don't give it a 'Name' tag, it just uses "Packer Builder". With Openstack, there doesn't appear to be that option, so it just uses the image name. This isn't favorable if there is a period in the image name (as one would expect with a version number.) For instance - centos-7.1-06302015 as an instance name causes DNS confusion, thinking that both domain.com and .1-06302015.domain.com are both parts of its FQDN, bringing on some Puppet chaos, etc. If we had the ability to use a more generic name like the AWS builder, that would be helpful!

Thanks,

Chris

Hello,

Have you seen this?

image_name (string) - The name of the resulting image.

is this what you are after?

Hello,

The image_name is the name of the resulting image, but the Openstack plugin also uses that value for the temporary instance name, which ends up being the system hostname, and having periods in that is confusing DNS. Would be helpful to be able to specify a name for the temporary instance as well (for instance, you can include the 'Name' key in the AWS builder).

Hi Chris,

Did you found a solution to name the temporary openstack VM differently than the resulting image name in packer? I'm having this same problem now.
Any guidance on this would be much appreciated!

Thanks,
Fernando

This seems a bit broken. You might be able to work around it by setting another hostname in userdata.
