heat-jeos image should print out the location of the generated image

[asalkeld]

It is really confusion to split the image creation into
"heat-jeos tdl" and "heat-jeos image"

I didn't realize that I needed to do the first one until my image didn't work and found that the cfn-tools were all of size 0

How about the following:

$ heat-jeos list
Name  Description
--------   ----------------
[lists available tdl, description from within the tdl]

$ heat-jeos create [name of tdl] <- nice and simple
- we make the image name based on the basename of the tdl (no arch, distro, bla bla)
- It does the same as the original "heat jeos create" BUT no glance registration.
- Print out the command needed to register with glance (it is only one command - no point in wrapping it)
- really simple, flexible and not confusing.

$ heat-jeos delete [name of tdl]

I'm in favour of all of these suggestions except for this: I think we should still support a command that does the registration.

Right now when you want to set up heat, you have to do a lot of steps and one of them is:

sudo -E heat-jeos -y create F16 x86_64 cfntools

and it does everything. Now you'd need to have two commands:

sudo -E heat-jeos -y create F16-x86_64-cfntools
glance add name=F16-x86_64-cfntools is_public=true disk_format=qcow2 container_format=ovf < /var/lib/libvirt/images/F16-x86_64-cfntools-jeos.qcow2

It would complicate the getting started guide (the glance command depends on the output of heat-jeos which people could miss) and it would probably be less scriptable.

What if we added a --register-with-glance option to heat-jeos create? We would still print out the resulting image path, the glance command to run, etc. But we'd still have a single command that does it all.

Is there a reason we should tear out glance registration completely?

At the moment I believe we need glance registration as a feature. If Richard Jones does something with registration of images (see http://fedoraproject.org/wiki/Features/OpenStack_using_Oz_for_image_building) it may make more sense to integrate with that upstream longer term.

The suggested flag --register-with-glance makes good sense

OK, sounds good to me. Main point is to make it more obvious to use.

My latest suggestion on mailing list based upon Angus's original thoughts:

heat-jeos list

id distro name distro version arch

F16-x86_64 Fedora 16 x86_64
U10.04.4-amd64 Ubuntu 10.04 amd64
F17-i386 Fedora 16 i386

distro name/version/arc would be parsed from the tdl files

heat-jeos create U10.04.4-amd64 --register-with-glance
