maas-lxd

This is a simple project to provide MAAS with KVM POD capability in a LXD container.

Getting Started

• LXD must be installed and working. LXD Install Guide
• KVM must be installed and working. KVM Install Guide
• If running LXC version 3.0 or above, ensure that you have an LXD storage pool named "default" set up; this project assumes it is.

Running

If using a version of lxd that supports storage pools (>2.0), ensure that the pool name in 'root-device' matches what you have in lxc storage list

Run the make-maas.sh and name your MAAS container.

./make-maas.sh maas

This applies the included profile to a container, tries to get it's IP address and adds a dnsmasq entry to LXD so that containers which PXE will be sent to MAAS. Note that DNS/DHCP is still done via LXD. If you are using the default NAT configuration you'll be able to spin up KVM's inside this LXD container through MAAS. If you're using a bridged network setup you'll need to handle network configuration to address how you want DHCP/DNS/PXE to be routed.

The install can take some time as it has to install several packages. When it is complete you can access your MAAS node at http://MAASIP:5240/MAAS

Using MAAS

See the MAAS Documentation for up to date information. A few quick comments

• An admin user has been setup, password/login are admin/admin
• You can use MAAS PODS, but that is not automatically added currently with this script. To do so:
  • Go to the PODS page in MAAS
  • Select "Add pod"
  • Select Virsh (virtual system) as the Pod type
  • For Virsh address use "qemu:///system"
  • Optionally name your pod

Once PODs are configured you can create them directly from the MAAS interface. MAAS will also compose a pod for juju when juju requests a machine. Additionally, Juju can bootstrap into a MAAS pod allowing MAAS and the juju controller to both live inside this LXD on a single machine. Recall that if you are doing this to manage external hardware you will have to address more advanced networking than is currently handled here.

For more information on using Juju with MAAS see Using a MAAS cloud in the juju documentation.
