It is true that IPA and FuelAgent share a lot of functionality in common. However there is a major difference between them which is that they are intended to be used to solve a different problem. IPA is a solution for provision-use-destroy-use_by_different_user use-case and is really great for

Just a short explanation of Fuel use case. Fuel use case is not a cloud. Fuel is a deployment tool. We install OS on bare metal servers and on VMs and then configure this OS using Puppet. We have been using Cobbler as our OS provisioning tool since the beginning of Fuel. However, Cobbler assumes

Good day Ironicers. I do not want to discuss questions like Is feature X good for release Y? or Is feature Z in Ironic scope or not?. I want to get an answer for this: Is Ironic a flexible, easy extendable and user-oriented solution for deployment? Yes, it is I think. IPA is the great

Hi folks, Thank you for additional explanation, it does clarify things a bit. I'd like to note, however, that you talk a lot about how _different_ Fuel Agent is from what Ironic does now. I'd like actually to know how well it's going to fit into what Ironic does (in additional to your

We assume next step will be to put provision data (disk partition scheme, maybe other data) into driver_info and make Fuel Agent driver able to serialize those data (special format) and implement a corresponding data driver in Fuel Agent for this format. Again very simple. Maybe it is time to

Vladimir, IMO there is more global problem. Anyone who wants to use baremetal deploy service should resolve problems with power management, PXE/iPXE support, DHCP, etc. Or he/she can use Ironic. User has his own vision of deploy workflow and features needed for it. He hears from Ironic people:
