I. Overview

1. Overview:

• OpenStack is an open source platform that uses pooled virtual resources to build and manage private and public clouds

  • It is mostly deployed as infrastructure-as-a-service (IaaS)

  • The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center.

  • OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. As of 2012, it was managed by the OpenStack Foundation, a non-profit corporate entity established in September 2012[3] to promote OpenStack software and its community.

2. Core Components:

• Nova: The OpenStack project that provides a way to provision compute instances (aka virtual servers). Nova supports creating virtual machines.

• Neutron: It is the network service within OpenStack. Manages & Performs all network configurations, operations.

• Glance: Maintains and manages server images in Cloud

• Horizon: The implementation of OpenStack’s Dashboard, which provides a web based user interface to OpenStack services including Nova, Swift, Keystone, etc.

• Cinder: It is the block storage service of OpenStack, providing virtual storage for virtual machines in the system.

• Swift: The object storage component of OpenStack, is a scalable and distributed storage system.

• Keystone: It is the authentication and authorization system of OpenStack.

II.Install and Create Ubuntu/virtual machine

A. Installing

• Ubuntu download link: https://ubuntu.com/download/desktop

• Virtual box download link: https://www.virtualbox.org/wiki/Downloads

Note: - My ubuntu version is 20.04 and my virtual box version is 6.1.34

B. Settings for KOLLA-ANSIBLE

• Kolla provides Docker containers and Ansible playbooks to provide production-ready containers and deployment tools for operating OpenStack clouds.

• System Requirements:

  • Operating System: Ubuntu

  • Desktop Hypervisior: VirtualBox

• Virtual machine requirement:

  • 2 network interfaces:

  • enp0s3: 10.0.2.15/24

  • enp0s8: 10.0.3.15/24

- 8GB main memory
- 2 disk with 20GB

III.Setup and Deloy OpenStack AIO inside VM with Kolla ( using a virtual environment )

1. Update and Install dependencies

$ sudo apt update 

$ sudo apt install python3-dev libffi-dev gcc libssl-dev

2. Setup and create virtual environment

• Install the virtual environment dependencies (Using virtualenv)

$ sudo apt install python3-venv

• create virtual environment

$ python3 -m venv /path/to/venv
$ source /path/to/venv/bin/activate

• Check the last version:

$ pip install -U pip

3. Install Ansible and Kolla-ansible

Note: using a virtual environment before run.

• Install Ansible

$ pip install 'ansible>=4,<6'

• Install Kolla-ansible:

$pip install git+https://opendev.org/openstack/kolla-ansible@master

• Install Ansible Galaxy dependencies:

$ kolla-ansible install-deps

3. Config Ansible and Kolla-ansible

• Create the /etc/kolla directory:

$ sudo mkdir -p /etc/kolla
$ sudo chown $USER:$USER /etc/kolla

• Copy globals.yml and passwords.yml to /etc/kolla directory:

$ cp -r /path/to/venv/share/kolla-ansible/etc_examples/kolla/* /etc/kolla

• Configure Ansible:

$ sudo mkdir -p /etc/ansible
$ config="[defaults]\nhost_key_checking=False\npipelining=True\nforks=100"
$ echo -e $config >> /etc/ansible/ansible.cfg

• Check configurations:

$ ansible -i all-in-one all -m ping

ping success

• Create diskspace partition for Cinder:

$ sudo pvcreate /dev/sdb
$ sudo vgcreate cinder-volumes /dev/sdb

• Generate Passwords for Kolla:

$ kolla-genpwd

• Configure globals.yml:

kolla_base_distro: "ubuntu"

network_interface: enp0s3
neutron_external_interface: enp0s8
kolla_internal_vip_address: 10.0.2.15

enable_haproxy: "no"

4. Deloy openstack

• Bootstrap servers with kolla deploy dependencies

• Do pre-deployment checks for hosts

• Pull Images to VM

• Deploy

• Post deloy: ( Create /etc/kolla/admin-openrc.sh )

5. Using Openstack

• Install Openstack CLI:

$ pip install python-openstackclient python-glanceclient python-neutronclient

• Create /etc/kolla/admin-openrc.sh

$ source /etc/kolla/admin-openrc.sh

• Generate token:

$ openstack token issue

• Openstack Login page

• Openstack Dashboard
