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”.

Requirements for this tutorial:

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 user

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

3. 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/* .

4. create a partition for cinder volume

$ sudo fdisk /dev/vdb+--------+------+----------------+
| Device | Size | Type |
+--------+------+----------------+
| vdb1 | 100G | 8e (Linux LVM) |
+--------+------+----------------+

5. Create LVM disk for cinder service

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

6. Edit ansible config

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

7. Generate kolla password

$ kolla-genpwd

8. 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"
...

9. 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

10. install openstack CLI client

pip install python3-openstackclient

11. Testing installation

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

12. Check openstack services

$ source /etc/kolla/admin-openrc.sh$ openstack service list
