devstack with Vagrant and libvirt

What's This About?

The purpose of this project is to easily fire up a VM with a running OpenStack inside, ready to accept deployments of Kubernetes clusters. OpenStack is provisioned inside the VM via devstack. The VM itself is created with Vagrant and libvirt.

Minimum Requirements

  • Ram: 8GB
  • Disc: 50GB
  • CPUs: 4 Cores

Preparation of Ubuntu 14.04.3 Host

libvirt

sudo apt-get install libvirt-bin qemu qemu-system-x86

Vagrant 1.8.1+

Download from website, then:

sudo dpkg -i vagrant_1.8.1_x86_64.deb
sudo apt-get install libvirt-dev
vagrant plugin install vagrant-libvirt
vagrant plugin install vagrant-host-shell
vagrant plugin install vagrant-reload

Ansible 1.9+

sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible

For older versions of Ubuntu

sudo apt-get remove pip
sudo apt-get install python-setuptools python-dev build-essential
sudo easy_install pip
sudo pip install ansible

Reboot system.

Preparation of CentOS 7 Host

Add epel repository:

sudo yum install epel-release

libvirt

sudo yum install libvirt qemu qemu-system-x86

Install Vagrant 1.8.1+

Download from website, then:

sudo yum install vagrant_1.8.1_x86_64.rpm
sudo yum install gcc libvirt-devel
vagrant plugin install vagrant-libvirt
vagrant plugin install vagrant-host-shell
vagrant plugin install vagrant-reload

Ansible 1.9+

sudo yum install ansible

Reboot the system

Gotchas

Vagrant usually stores machine images underneath /var, so please make sure that you have at least 30GB of free space on the file system that is hosting /var.

Ready... Set... Go...

Start the provisioning of devstack in the VM with:

vagrant up --provider libvirt

Environment Variables

  • DEVSTACK_MEM how much RAM to give to the VM, in MB, defaults to 6144MB
  • DEVSTACK_CPUS how many CPUs to give to the VM, defaults to 4

So for custom memory and CPUs, you could do:

DEVSTACK_MEM=8192 DEVSTACK_CPUS=6 vagrant up --provider libvirt

Basic Usage

Horizon is running on port 80, user demo or admin, password secretsecret. To check on the VM's IP address, you can do:

vagrant ssh
ifconfig eth0

After restarting the physical host, the VM unfortunately must be provisioned again:

vagrant destroy
vagrant up
