Automated Setup

This section provides information on the development tools provided by kayobe to automate the deployment of various development environments.

For a manual procedure, see development-manual.

Overview

The kayobe development environment automation tooling is built using simple shell scripts. Some minimal configuration can be applied by setting the environment variables in dev/config.sh. Control plane configuration is typically provided via the kayobe-config-dev repository, although it is also possible to use your own kayobe configuration. This allows us to build a development environment that is as close to production as possible.

Environments

The following development environments are supported:

• Overcloud (single OpenStack controller)
• Seed
• Seed hypervisor
• Seed VM

The seed VM environment may be used in an environment already deployed as a seed hypervisor.

Overcloud

Preparation

Clone the kayobe repository:

git clone https://opendev.org/openstack/kayobe.git

Change the current directory to the kayobe repository:

cd kayobe

Clone the kayobe-config-dev repository to config/src/kayobe-config:

mkdir -p config/src
git clone https://opendev.org/openstack/kayobe-config-dev.git config/src/kayobe-config

Inspect the kayobe configuration and make any changes necessary for your environment.

If using Vagrant, follow the steps in development-vagrant to prepare your environment for use with Vagrant and bring up a Vagrant VM.

If not using Vagrant, the default development configuration expects the presence of a bridge interface on the OpenStack controller host to carry control plane traffic. The bridge should be named breth1 with a single port eth1, and an IP address of 192.168.33.3/24. This can be modified by editing config/src/kayobe-config/etc/kayobe/inventory/group_vars/controllers/network-interfaces. Alternatively, this can be added using the following commands:

sudo ip l add breth1 type bridge
sudo ip l set breth1 up
sudo ip a add 192.168.33.3/24 dev breth1
sudo ip l add eth1 type dummy
sudo ip l set eth1 up
sudo ip l set eth1 master breth1

Usage

If using Vagrant, SSH into the Vagrant VM and change to the shared directory:

vagrant ssh
cd /vagrant

If not using Vagrant, run the dev/install-dev.sh script to install kayobe and its dependencies in a virtual environment:

./dev/install-dev.sh

Note

This will create an editable install <installation-editable>. It is also possible to install kayobe in a non-editable way, such that changes will not been seen until you reinstall the package. To do this you can run ./dev/install.sh.

Run the dev/overcloud-deploy.sh script to deploy the OpenStack control plane:

./dev/overcloud-deploy.sh

Upon successful completion of this script, the control plane will be active.

Testing

Scripts are provided for testing the creation of virtual and bare metal instances.

Virtual Machines

The control plane can be tested by running the dev/overcloud-test-vm.sh script. This will run the init-runonce setup script provided by Kolla Ansible that registers images, networks, flavors etc. It will then deploy a virtual server instance, and delete it once it becomes active:

./dev/overcloud-test-vm.sh

Bare Metal Compute

For a control plane with Ironic enabled, a "bare metal" instance can be deployed. We can use the Tenks project to create fake bare metal nodes.

Clone the tenks repository:

git clone https://opendev.org/openstack/tenks.git

Optionally, edit the Tenks configuration file, dev/tenks-deploy-config-compute.yml.

Run the dev/tenks-deploy-compute.sh script to deploy Tenks:

./dev/tenks-deploy-compute.sh ./tenks

Check that Tenks has created VMs called tk0 and tk1:

sudo virsh -c qemu+unix:///system?socket=/var/run/libvirt-tenks/libvirt-sock list --all

Verify that VirtualBMC is running:

~/tenks-venv/bin/vbmc list

We are now ready to run the dev/overcloud-test-baremetal.sh script. This will run the init-runonce setup script provided by Kolla Ansible that registers images, networks, flavors etc. It will then deploy a bare metal server instance, and delete it once it becomes active:

./dev/overcloud-test-baremetal.sh

The machines and networking created by Tenks can be cleaned up via dev/tenks-teardown-compute.sh:

./dev/tenks-teardown-compute.sh ./tenks

Upgrading

It is possible to test an upgrade from a previous release by running the dev/overcloud-upgrade.sh script:

./dev/overcloud-upgrade.sh

Seed

These instructions cover deploying the seed services directly rather than in a VM. See development-automated-seed-vm for instructions covering deployment of the seed services in a VM.

Preparation

Clone the kayobe repository:

git clone https://opendev.org/openstack/kayobe.git

Change to the kayobe directory:

cd kayobe

Clone the kayobe-config-dev repository to config/src/kayobe-config:

mkdir -p config/src
git clone https://opendev.org/openstack/kayobe-config-dev.git config/src/kayobe-config

Inspect the kayobe configuration and make any changes necessary for your environment.

The default development configuration expects the presence of a bridge interface on the seed host to carry provisioning traffic. The bridge should be named breth1 with a single port eth1, and an IP address of 192.168.33.5/24. This can be modified by editing config/src/kayobe-config/etc/kayobe/inventory/group_vars/seed/network-interfaces. Alternatively, this can be added using the following commands:

sudo ip l add breth1 type bridge
sudo ip l set breth1 up
sudo ip a add 192.168.33.5/24 dev breth1
sudo ip l add eth1 type dummy
sudo ip l set eth1 up
sudo ip l set eth1 master breth1

Usage

Run the dev/install.sh script to install kayobe and its dependencies in a virtual environment:

./dev/install.sh

Run the dev/seed-deploy.sh script to deploy the seed services:

./dev/seed-deploy.sh

Upon successful completion of this script, the seed will be active.

Testing

The seed services may be tested using the Tenks project to create fake bare metal nodes.

Clone the tenks repository:

git clone https://opendev.org/openstack/tenks.git

Optionally, edit the Tenks configuration file, dev/tenks-deploy-config-overcloud.yml.

Run the dev/tenks-deploy-overcloud.sh script to deploy Tenks:

./dev/tenks-deploy-overcloud.sh ./tenks

Check that Tenks has created a VM called controller0:

sudo virsh list --all

Verify that VirtualBMC is running:

~/tenks-venv/bin/vbmc list

The machines and networking created by Tenks can be cleaned up via dev/tenks-teardown-overcloud.sh:

./dev/tenks-teardown-overcloud.sh ./tenks

Seed Hypervisor

The seed hypervisor development environment is supported for CentOS 7. The system must be either bare metal, or a VM on a system with nested virtualisation enabled.

Preparation

The following commands should be executed on the seed hypervisor.

Clone the kayobe repository:

git clone https://opendev.org/openstack/kayobe.git

Change the current directory to the kayobe repository:

cd kayobe

Clone the add-seed-and-hv branch of the kayobe-config-dev repository to config/src/kayobe-config:

mkdir -p config/src
git clone https://github.com/markgoddard/dev-kayobe-config -b add-seed-and-hv config/src/kayobe-config

Inspect the kayobe configuration and make any changes necessary for your environment.

Usage

Run the dev/install-dev.sh script to install kayobe and its dependencies in a virtual environment:

./dev/install-dev.sh

Note

This will create an editable install <installation-editable>. It is also possible to install kayobe in a non-editable way, such that changes will not been seen until you reinstall the package. To do this you can run ./dev/install.sh.

Run the dev/seed-hypervisor-deploy.sh script to deploy the seed hypervisor:

./dev/seed-hypervisor-deploy.sh

Upon successful completion of this script, the seed hypervisor will be active.

Seed VM

The seed VM should be deployed on a system configured as a libvirt/KVM hypervisor, using development-automated-seed-hypervisor or otherwise.

Preparation

The following commands should be executed on the seed hypervisor.

Clone the kayobe repository:

git clone https://opendev.org/openstack/kayobe.git

Change to the kayobe directory:

cd kayobe

Clone the add-seed-and-hv branch of the kayobe-config-dev repository to config/src/kayobe-config:

mkdir -p config/src
git clone https://github.com/markgoddard/dev-kayobe-config -b add-seed-and-hv config/src/kayobe-config

Inspect the kayobe configuration and make any changes necessary for your environment.

Usage

Run the dev/install-dev.sh script to install kayobe and its dependencies in a virtual environment:

./dev/install-dev.sh

Note

This will create an editable install <installation-editable>. It is also possible to install kayobe in a non-editable way, such that changes will not been seen until you reinstall the package. To do this you can run ./dev/install.sh.

Run the dev/seed-deploy.sh script to deploy the seed VM:

./dev/seed-deploy.sh

Upon successful completion of this script, the seed VM will be active. The seed VM may be accessed via SSH as the stack user:

ssh stack@192.168.33.5

It is possible to test an upgrade by running the dev/seed-upgrade.sh script:

./dev/seed-upgrade.sh
