OpenStack : Deploy All in One OpenStack Dengan Kolla-ansible

 

Halo semua pada kesempatan kali ini kami akan share tutorial tentang cara deploy openstack dengan cara otomatis menggunakan kolla-ansible. Untuk environment yang akan kami gunakan sebagai berikut :

| Key  | Value |
| ----- | --- |
| Interfaces   | 2 interface, enp1s0 : 10.20.21.0/24, enp7s0 : isolated network  |
| Ram | 8GB  |
| vCPUs| 2 |
| Storage| 2 Disk, 1 Disk Sistem (30-40GB), 1 Cinder volume(50GB) |
| Operating System | Ubuntu 18.04 |

VM atau server diatas berjalan di atas KVM, untuk yang belum pernah belajar KVM bisa mampir di link berikut. Untuk versi openstack yang akan kita deploy adalah ussuri. untuk tahapannya seperti berikut :

1. Prerequisite

2. Setup untuk deploy

3. Deploy

4. Post Deploy

Ya kurang lebih seperti diatas, untuk tahapannya. Oke langsung saja ke panduannya :

1. Prerequisite

Pada Tahap ini kita akan melakukan persiapan sebelum melakukan setup dan menuju ke deploy.

- Install docker, disarankan versi 18 terbaru, jika menggunakan versi 20, kami coba terdapat error saat verifikasi

```bash
$ docker version
```

- Konfigurasi LVM

```bash
# check all disk
$ sudo fdisk -l
# LVM 
$ sudo pvcreate -f /dev/vdx
$ sudo pvs
$ sudo vgcreate -f openstack_cinder /dev/vdx
$ sudo vgs
```

- Update and Upgrade package

```bash
$ sudo apt-get update
$ sudo apt-get upgrade
```

2. Setup untuk deploy

```bash
# Install package
$ sudo apt install python3-dev python3-venv libffi-dev gcc libssl-dev git

# Create virtual environment ('openstack-ussuri' bebas untuk dirubah)
$ python3 -m venv $HOME/openstack-ussuri
$ source $HOME/openstack-ussuri/bin/activate

# Akan menjadi seperti berikut
(openstack-ussuri) sulaiman@al-faruq:~$

# Upgrade PIP
(openstack-ussuri) sulaiman@al-faruq:~$ pip install -U pip
```

Install ansible and Kolla-ansible

```bash
# install ansible
(openstack-ussuri) sulaiman@al-faruq:~$ pip install ansible

# ansible config
(openstack-ussuri) sulaiman@al-faruq:~$ vim $HOME/ansible.cfg
...
[defaults]
host_key_checking=False
pipelining=True
forks=100
...

# install kolla-ansible
(openstack-ussuri) sulaiman@al-faruq:~$ pip install kolla-ansible 
(openstack-ussuri) sulaiman@al-faruq:~$ sudo mkdir /etc/kolla
(openstack-ussuri) sulaiman@al-faruq:~$ sudo chown $USER:$USER /etc/kolla
(openstack-ussuri) sulaiman@al-faruq:~$ cp $HOME/openstack-ussuri/share/kolla-ansible/etc_examples/kolla/* /etc/kolla/
(openstack-ussuri) sulaiman@al-faruq:~$ cp $HOME/openstack-ussuri/share/kolla-ansible/ansible/inventory/all-in-one .
(openstack-ussuri) sulaiman@al-faruq:~$ vim /etc/kolla/globals.yml
...
kolla_base_distro: "ubuntu"
kolla_install_type: "source"
openstack_release: "ussuri"
kolla_internal_vip_address: "10.20.21.200"
kolla_external_vip_address: "{{ kolla_internal_vip_address }}"
network_interface: "enp1s0"
neutron_external_interface: "enp7s0"
neutron_plugin_agent: "openvswitch"
enable_haproxy: "yes"
enable_cinder: "yes"
enable_cinder_backend_lvm: "yes"
keystone_token_provider: 'fernet'
cinder_volume_group: "openstack_cinder"
nova_compute_virt_type: "qemu"
...
```

3. Deploy

```bash
# generate password
(openstack-ussuri) sulaiman@al-faruq:~$ kolla-genpwd
(openstack-ussuri) sulaiman@al-faruq:~$ kolla-ansible -i all-in-one bootstrap-servers
(openstack-ussuri) sulaiman@al-faruq:~$ kolla-ansible -i all-in-one prechecks
(openstack-ussuri) sulaiman@al-faruq:~$ kolla-ansible -i all-in-one deploy
```

4. Post Deploy

```bash
(openstack-ussuri) sulaiman@al-faruq:~$ pip install python-openstackclient python-neutronclient python-glanceclient
(openstack-ussuri) sulaiman@al-faruq:~$ kolla-ansible post-deploy
(openstack-ussuri) sulaiman@al-faruq:~$ source /etc/kolla/admin-openrc.sh
(openstack-ussuri) sulaiman@al-faruq:~$ vim openstack-ussuri/share/kolla-ansible/init-runonce
...
ENABLE_EXT_NET=${ENABLE_EXT_NET:-1}
EXT_NET_CIDR=${EXT_NET_CIDR:-'10.20.21.0/24'}
EXT_NET_RANGE=${EXT_NET_RANGE:-'start=10.20.21.150,end=10.20.21.199'}
EXT_NET_GATEWAY=${EXT_NET_GATEWAY:-'10.20.21.1'}
...
(openstack-ussuri) sulaiman@al-faruq:~$ openstack-ussuri/share/kolla-ansible/init-runonce
# hasilnya seperti berikut
...
+----------------------------+-----------+
| Field                      | Value     |
+----------------------------+-----------+
| OS-FLV-DISABLED:disabled   | False     |

| swap                       |           |
| vcpus                      | 8         |
+----------------------------+-----------+

Done.

To deploy a demo instance, run:

openstack server create \
    --image cirros \
    --flavor m1.tiny \
    --key-name mykey \
    --network demo-net \
    demo1

```

```bash
# check openstack service
(openstack-ussuri) sulaiman@al-faruq:~$ openstack service list

# check password login horizon
(openstack-ussuri) sulaiman@al-faruq:~$ grep keystone_admin_password /etc/kolla/passwords.yml
```
  

5. Verifikasi

- Akses dashboard openstack dengan ip address VIP (10.20.21.200) pada web browser 

- Login dengan user 'admin' dan password yang sudah dicheck sebelumnya

Yaps, sekian dulu, sampai jumpa di tutorial berikutnya!
