You need to configure bare metal servers to PXE boot on the network +interface where they can reach the MAAS server. With nodes set to boot from a PXE image, +they will start, look for a DHCP server, receive the PXE boot details, boot the image, +contact the MAAS server and shut down. + +During this process, the MAAS server will be passed information about the node, including +the architecture, MAC address and other details which will be stored in the database of +nodes. You can accept and commission the nodes via the web interface. When the nodes have +been accepted the selected series of Ubuntu will be installed. + + +Appendix C: Machine Constraints +------------------------------- +Juju and MAAS together allow you to assign different roles to servers, so that hardware and software can be configured according to their roles. We have briefly mentioned and used this feature in our example. Please visit Juju Machine Constraints https://jujucharms.com/docs/stable/charms-constraints and MAAS tags https://maas.ubuntu.com/docs/tags.html for more information. + + +Appendix D: Offline Deployment +------------------------------ +When you have limited access policy in your environment, for example, when only the Jump Host has Internet access, but not the rest of the servers, we provide tools in JOID to support the offline installation. + +The following package set is provided to those wishing to experiment with a ‘disconnected +from the internet’ setup when deploying JOID utilizing MAAS. These instructions provide +basic guidance as to how to accomplish the task, but it should be noted that due to the +current reliance of MAAS and DNS, that behavior and success of deployment may vary +depending on infrastructure setup.

In addition to HA or non-HA +mode, it also supports deploying from the latest development tree. + +JOID heavily utilizes the technology developed in Juju and MAAS. + +Juju_ is a state-of-the-art, open source modelling tool for operating software +in the cloud. Juju allows you to deploy, configure, manage, maintain, and scale +cloud applications quickly and efficiently on public clouds, as well as on +physical servers, OpenStack, and containers.

It lets you treat physical servers like virtual +machines (instances) in the cloud. Rather than having to manage each server +individually, MAAS turns your bare metal into an elastic cloud-like resource. +Machines can be quickly provisioned and then destroyed again as easily as you +can with instances in a public cloud. ... In particular, it is designed to work +especially well with Juju, the service and model management service.

Another VM is created to be managed by +MAAS as a bootstrap node for Juju. The rest of the resources, bare metal or +virtual, will be registered and provisioned in MAAS.
