Introduction:

Scripts that install a MAAS VM on a baremetal server, then install a juju client on the same VM and configure the basic setup, including bootstrapping a juju controller.

Requirements:

Internet connectivity to internet from host.
Sudo permissions on the host.
SSH Agent with the key that permits logins with qemu_user to the host.
Ideally it has be executed on an empty box, with only Bionic running.
If libvirtd is running, DHCP has to be enabled on the default network. And the "default" network must be on 192.168.122.0/24

Installation:

git clone https://github.com/ivanhitos/MAASJujuBuilder.git

cd MAASJujuBuilder

./mjb.sh --maas_ip "IPofMAAS" --dns "DNSSERVERS" --proxy "ProxyIP" --lpusername "LaunchPad UserID" --maas_password "Password for MAAS" \
--maas_startdhcp "FirstIPofDHCP" --maas_enddhcp "LastIPofDHCP"  --qemu_user "Qemu user for qemu+ssh" --release "bionic"

Example without proxy:


./mjb.sh --maas_ip "192.168.122.3" --dns "192.168.122.1" --lpusername "ivanhitos" --maas_password "ubuntu" \
--maas_startdhcp "192.168.122.220" --maas_enddhcp "192.168.122.250" --qemu_user "ivan" --release "bionic"

Example with proxy:


./mjb.sh --maas_ip "192.168.122.3" --dns "192.168.122.1" --proxy "http://squid.internal:3128" --lpusername "ivanhitos" --maas_password "ubuntu" \
--maas_startdhcp "192.168.122.220" --maas_enddhcp "192.168.122.250" --qemu_user "ubuntu" --release "bionic"

Description:

It will create a Bionic VM called MAAS1 on "IPofMAAS" with the latest stable version of MAAS from the Ubuntu archives, the default subnet is 192.168.122.0/24 and it cannot be changed for now. MAAS will be accessible on http://IPofMAAS:5240/MAAS User: Ubuntu, PASS: "Password for MAAS".

It will bootstrap a Juju controller.

If something failed:

Destroy the maas1 vm:

uvt-kvm destroy maas1

Re-add DHCP:

cd MAASJujuBuilder
virsh net-destroy default
/usr/bin/virsh net-define default.xml   # this was backed up during the execution of mjb.sh
/usr/bin/virsh net-start default

Fix whatever failed and try the execution of ./mjb.sh again

Still to do:

Add additional subnets and configure spaces.
Improve do_cmd function.
Import Juju bundles.
Make more arguments optional
