Deploy Openstack All-in-one with Kolla-ansible

What is openstack ?> “OpenStack is an open source cloud computing infrastructure software project and is one of the three most active open source projects in the world”. More details about openstack click here

Requirements for this tutorial:- Ubuntu 18.04 CPU 8 core,

• 8 GB RAM
• storage vda 50 GB, vdb 50G
• 2 network interfaces ens3 > 10.20.20.10. ens9 > 10.30.30.10
• Kolla ansible, - here

Lets build, setup on vm ubuntu

1. Update, upgrade server and install dependency

   $ sudo apt-get update; sudo apt-get upgrade
   $ sudo apt-get install python3-dev libffi-dev gcc libssl-dev
   $ sudo apt-get install python3-pip
   

2. create a new userThis case user named kolla, then set kolla user as sudoer without password.

$ sudo useradd kolla -m -s /bin/bash
$ sudo vim /etc/sudoers.d/kolla
...
kolla ALL=(ALL) NOPASSWD: ALL
...

$ su - kolla

1. Install kolla-ansible

   $ sudo pip3 install -U pip
   $ sudo pip3 install ansible
   $ pip3 install kolla-ansible==10.0
   $ sudo mkdir -p /etc/kolla
   $ sudo chown $USER:$USER /etc/kolla
   $ cp -r /usr/local/share/kolla-ansible/etc_examples/kolla/* /etc/kolla
   $ cp /usr/local/share/kolla-ansible/ansible/inventory/* .
   

2. create a partition for cinder volumefor tutorial create partition lvm you can see here.

$ sudo fdisk /dev/vdb

+--------+------+----------------+
| Device | Size |      Type      |
+--------+------+----------------+
| vdb1   | 100G | 8e (Linux LVM) |
+--------+------+----------------+

1. Create LVM disk for cinder service

   sudo pvcreate -f /dev/vdb1
   sudo pvs
   sudo vgcreate -f cinder-volumes /dev/vdb1
   sudo vgs
   

2. Edit ansible config

   $ sudo vim /etc/ansible/ansible.cfg
   ...
   [defaults]
   host_key_checking=False
   pipelining=True
   forks=100
   ...
   

3. Generate kolla password

   $ kolla-genpwd
   

4. Edit kolla configuration

   $ vi /etc/kolla/globals.yml
   ...
   kolla_base_distro: "ubuntu"
   kolla_install_type: "source"
   openstack_release: "ussuri"
   kolla_internal_vip_address: "10.20.20.10"
   network_interface: "ens3"
   neutron_external_interface: "ens9"
   neutron_plugin_agent: "openvswitch"
   enable_heat: "yes"
   enable_neutron_provider_networks: "yes"
   nova_compute_virt_type: "kvm"
   enable_cinder: "yes"
   enable_cinder_backend_lvm: "yes"
   cinder_volume_group: "cinder-volumes"
   enable_neutron_qos: "yes"
   enable_openstack_core: "yes"
   enable_haproxy: "no"
   ...
   

5. Deployment kolla

   kolla-ansible -i all-in-one bootstrap-servers
   kolla-ansible -i all-in-one prechecks
   kolla-ansible -i all-in-one deploy
   kolla-ansible -i all-in-one post-deploy
   kolla-ansible -i all-in-one check
   

6. install openstack CLI client

   pip install python3-openstackclient
   

7. Testing installationThere is a script that will create example networks, images, and so on.

$ cd /usr/local/share/kolla-ansible/
$ ./init-runonce

1. Check openstack services

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

$ openstack service list
