MAAS Juju Sandbox

Prepare a local environment using KVM virtual machines as the 'bare metal', ready for maas-installation before deployment with Juju.

maas-installation is a related project to install and configure the MAAS server, and add the nodes.

This project assumes to configure these two virsh NAT networks on the host machine:

Install and Configure Virtual Networks and Machines

On the host machine

scripts/00_install-host.sh to prepare the host machine, including creation of virsh networks
scripts/01_create-images.sh to download the latest cloud image, create VM disks and seed disk
scripts/02_define-machines.sh to define the VMs in virsh
scripts/03_generate-secrets.sh to generate the secrets and templates files to be used with maas-installation

The maas0 VM is defined in scripts/02_define-machines.sh
maas0 gets its configuration from maas0-seed.img, created by scripts/01_create-images.sh
- maas0/user-data stores the password to be set for the ubuntu user
- maas0/meta-data configures networking

Start maas0

virsh start maas0
- virsh console maas0 if you'd like to watch it boot
ssh -o StrictHostKeyChecking=no -l ubuntu 192.168.123.2
Secrets files to be used with maas-installation have been created in ./maas-installation/

Using the mass-installation project code on maas0, install and configure MAAS

Use the generated secrets as the maas-installation/secrets/ files
During installation, maas-installation/scripts/install-mass.sh also configures MAAS 'Global Kernel Parameters' to set "console=ttyS0" for virsh console
Add the nodes listed in maas-installation/secrets/host-inventory.txt to MAAS
- maas-installation/scripts/maas-add-hosts.sh -d
Add this maas cloud to Juju
- juju add-cloud maas-cloud ${generated_secrets}/maas-clouds.yaml
- juju add-credential maas-cloud ('maas-oath', when prompted, is the API key from maas-region apikey --username=maas-root)
