ansible-devstack

Provision a VM (As a default Ubuntu 20.04) and install a devstack inside the VM using libivrton a local machine

The primary use is to have a local Openstack setup so that you can develop tests or openstack itself. There are two ansible roles: provision and devstack:
provision - To create a VM
devstack - To install devstack on the provided VM

prerequisites

The vkhitrin.libguestfs collection should be installed

ansible-galaxy collection install vkhitrin.libguestfs

How to run

It's advisable to create a YAML file such as myfile.yml

libvirt_vm_name: myvm
libvirt_vm_memory_mb: 8000                                                  
libvirt_vm_vcpus: 2                                                         
tmp_image_path: /tmp/myvm.qcow2

And then run

$ ansible-playbook -i hosts -e @myfile.yml main.yml

It's possible to run only provisioning using the provison tag or devstack installation by using the devstack tag

Devstack

The default local.conf is taken from /devstack/templates/local.conf It's possible to supply a different local.conf by either overriding the file or passing the local_conf variable to point one with a different name.

local.conf templates

Currently there are 3 templates:

local.conf (default, The basic devstack)
kuryr.conf (Including Kuryr)
designate.conf (Including Designate)

If you want to use kuryr.conf or designate.conf you need to set the local_conf variable.
For example:

$ ansible-playbook -i hosts -e @myfile.yml -e local_conf=designate.conf main.yml

Connecting to the VM

You can find out the IP of the vm by running

$ sudo virsh doifaddr myvm

Or by looking at the hosts file

You can then connect using SSH using the stack user

$ ssh stack@<vm ip>

Cleanup

If you delete the VM and want to reprovsion it's important to remove the line with the VM name from the hosts file
