Untuk kebutuhan lab openstack setidaknya memiliki 1 host untuk controller dan 2 host untuk compute baik berupa mesin virtual maupun baremetal untuk spesifikasinya sebagai berikut :
| Node Name | Processor | RAM | Root / Volumes | Cinder Volumes | Ip Address |
|---|
| openstack-controller | 8 Core | 8 GB | 80 GB (sda) | | 10.79.0.10 |
| openstack-compute01 | 16 Core | 16 GB | 40 GB (sda) | 100 GB (sdb) | 10.79.0.11 |
| openstack-compute02 | 16 Core | 16 GB | 40 GB (sda) | 100 GB (sdb) | 10.79.0.12 |
Lalu untuk kebutuhan jaringan openstack dengan rincian sebagai berikut :
| Name | Network | Virtual IP | Interface |
|---|
| Internal | 10.79.0.0/24 | 10.79.0.254 | ens18 |
| Provider | 172.16.0.0/24 | | ens19 |
Semua node menggunakan sistem operasi Ubuntu 20.04 Focal dengan versi OpenStack Yoga dengan username setiap node bernama vq
Sesuaikan dengan environment lab anda
Rancangan Topologi#
Persiapan Cluster#
1. Membuat dan mendistribusikan ssh public key#

| ssh-keygen -t rsa -b 4096 -q -N ""
ssh-copy-id vq@10.79.0.10
ssh-copy-id vq@10.79.0.11
ssh-copy-id vq@10.79.0.12
|
2. Memverifikasi koneksi sesi ssh#
Eksekusi perintah pada openstack-controller dengan Kolla virtual environment
1
| for i in {0..2}; do ssh vq@10.79.0.1$i 'echo $(whoami) $(hostname)'; done
|
3. Memberikan full privileges sudo tanpa memasukan password#
Eksekusi perintah pada openstack-controller dengan Kolla virtual environment, openstack-compute01, dan openstack-compute02
1
| echo 'vq ALL=(ALL) NOPASSWD:ALL' | sudo tee /etc/sudoers.d/vq
|
4. Menambahkan mapping hosts nama node dan persiapan node#

10.79.0.10 openstack-controller
10.79.0.11 openstack-compute01
10.79.0.12 openstack-compute02

| sudo pvcreate /dev/sdb
sudo vgcreate cinder-volumes /dev/sdb
sudo vgdisplay cinder-volumes
sudo vgs
|
6. Memasang dependensi yang dibutuhkan oleh kolla-ansible#
Eksekusi perintah pada openstack-controller dengan Kolla virtual environment
1
2
| sudo apt update && sudo apt upgrade -y
sudo apt install -y gcc libffi-dev libssl-dev python3-dev python3-selinux python3-setuptools python3-venv python3-pip net-tools
|
Membuat dan mengaktifkan virtual environment kolla

| python3 -m venv kolla
source ~/kolla/bin/activate
|
Update pip dan install dependensi kolla-ansible

| sudo mkdir /etc/kolla
sudo chown $USER:$USER /etc/kolla
cp -r ~/kolla/share/kolla-ansible/etc_examples/kolla/passwords.yml /etc/kolla
cp -r ~/kolla/share/kolla-ansible/etc_examples/kolla/globals.yml /etc/kolla
cp -r ~/kolla/share/kolla-ansible/ansible/inventory/* ~/
