Deploy OpenStack dengan Juju dan MAAS

Instalasi Juju, konfigurasi cloud MAAS, penambahan credential, bootstrap controller, pembuatan model OpenStack, deployment bundle OpenStack, konfigurasi Keystone dan console Nova, akses Horizon, penambahan machine/unit, penghapusan machine/unit, cleanup environment, hingga command operasional Juju untuk model, controller, cloud, dan service machine.

Tutorial ini merapihkan catatan deploy OpenStack berbasis Juju charm dan MAAS.

1. Disable IPv6 Ubuntu

Edit /etc/sysctl.conf:

BASH 
sudo nano /etc/sysctl.conf

Tambahkan:

TEXT 
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Apply konfigurasi:

BASH 
sudo sysctl -p

2. Install Juju

BASH 
sudo snap install juju --classic

3. Tambahkan Cloud MAAS ke Juju

BASH 
juju add-cloud --local

Input contoh:

TEXT 
select cloud type : maas
Enter a name.... : maas
End Point : http://<MAAS_IP>:5240/MAAS

Ambil API key MAAS:

BASH 
sudo maas apikey --username=admin

Tambahkan credential:

BASH 
juju add-credential maas

Input contoh:

TEXT 
Enter credential name: maas
Replace local credential? (y/N): y
Select region [any region, credential is not region specific]: default
Using auth-type "oauth1".

4. Bootstrap Controller Juju

BASH 
nohup juju bootstrap maas maas-controller --debug --bootstrap-series=jammy --credential maas &

Alternatif:

BASH 
juju bootstrap maas maas-controller --debug

5. Buat Model OpenStack

BASH 
juju add-model openstack
juju add-model --config default-series=jammy openstack

6. Deploy OpenStack Bundle

Deploy dari charm store:

BASH 
juju deploy cs:bundle/openstack-base-80
juju deploy cs:bundle/openstack-base-79
juju deploy cs:bundle/openstack-base-65

Deploy dari repository bundle:

BASH 
git clone https://github.com/openstack-charmers/openstack-bundles
cd /home/<USER>/openstack-bundles/stable/openstack-base
juju add-model openstack
juju deploy ./bundle.yaml --debug

7. Konfigurasi Awal Keystone dan Console

BASH 
juju config keystone admin-password=<PASSWORD>
juju config nova-cloud-controller console-access-protocol=novnc

Cek password admin:

BASH 
juju run --unit keystone/0 leader-get admin_passwd

8. Akses Horizon

TEXT 
http://<HORIZON_IP>/horizon

9. Tambah Machine dan Unit

Tambah machine by hostname dari MAAS:

BASH 
sudo juju add-machine node10.maas --series="bionic"
juju add-machine node05.maas --series="jammy"
juju add-machine node06.maas --series="jammy"
juju add-machine node06.maas --series="focal"
sudo juju add-machine node13.maas --series="bionic" --debug

Tambah unit Ceph OSD dan Nova Compute:

BASH 
sudo juju add-unit --to 28 ceph-osd
sudo juju add-unit --to 28 nova-compute
juju add-unit --to 4 ceph-osd
juju add-unit --to 5 ceph-osd
juju add-unit --to 28 nova-compute
juju add-unit --to 4 nova-compute
sudo juju add-unit --to 8 ceph-osd
sudo juju add-unit --to 8 nova-compute
sudo juju add-unit --to 2 ceph

10. Remove Machine dan Unit

BASH 
sudo juju remove-machine 27 --force
sudo juju remove-machine 28 --force
sudo juju remove-machine 31 --force
juju remove-machine 5 --force
juju remove-unit postgresql/2
sudo juju remove-unit ceph-osd/10
sudo juju remove-unit ceph/3
sudo juju remove-machine 21
juju remove-unit ceph-osd/1

11. Clean OpenStack/Juju Environment

SSH ke controller:

BASH 
ssh -i .local/share/juju/ssh/jujuidrsa ubuntu@<CONTROLLER_IP>

Hapus controller, credential, dan cloud:

BASH 
juju kill-controller maas-controller
juju remove-credential maas maas
juju remove-cloud maas

12. Command Operasional Model dan Controller

BASH 
juju models
juju destroy-model [nama model]
juju controllers
juju destroy-controller [nama controller]
juju clouds
juju remove-cloud [nama cloud]

13. Menyalakan Service Juju Machine Manual

BASH 
sudo systemctl start jujud-machine-1/lxd/2*
sudo systemctl start jujud-machine-1/lxd/1*
sudo systemctl start jujud-machine-1/lxd/0*
sudo systemctl start jujud-machine-1*
