Same source image for multiple Cloud platforms

[Vince Do]

Hello, 

I'm wondering why, as far as I can see, it isn't possible to use the same source image to build multiple custom ones with different Builders.

I would like to start from an ISO or for example an Ubuntu Cloud Image and get as output an image for VMWare one for Openstack and a VirtualBox image. Does someone have an idea if this is somehow possible using Packer?

Best regards,

Vincenzo

Hello

Packer uses a 100% different approach.

Using the same provisioners (scripts/puppter/ansible, etc) will build boxes/vms on different providers (local/cloud) that after provision will be the same (or very similar)

Hi,

I was wondering about this too.

Alvaro: But should the starting point not be the same too, i.e. a base ISO or other image, otherwise it would be difficult to get the exact same versions of programs, and the exact same list of packages installed?

You can often use a local builder for example qemu to build an image and then post-process it to upload it to a cloud provider, but that is a _very_ advanced use case and if you don't get all the specific details for _that_ cloud right you image will be dead in the water. This is something I don't recommend unless you are very clear on the reason why you need to do that. 

The main reason for doing this is that you are the base image provider and there is no base image for a cloud to use.

Hello Rickard

first of all thank you for your reply. 

It may be an advanced scenario but I thought that why packer is there, to simplify the image creation process. Otherwise I would just have used the standard Ubuntu Cloud Image. Like for example, imagine I'm running two hosting platforms one on VMWare and one on Openstack and I know exactly how I need to configure my images for them to work on one or the other platform. So why exactly can't I start from a single source image and get different outputs still puzzles me.

Best regards,

Vincenzo

I didn't say you cant. On the contrary, I said it's possible. For an example see https://github.com/tmclaugh/suitcase
