docs: improve automated seed development info
* add 'bridge_type: linuxbridge' to tenks configuration to avoid dependency on OVS * extend seed development environment testing to include overcloud provisioning and deployment * remove seed hypervisor and seed VM environments. These are very stale, and largely replaced by a-universe-from-nothing. Add a link to that workshop on the same page Change-Id: I9928e5912e6770bdcc1d5d0884d2f101c16ee6a9

Seed Hypervisor
|
||||
===============
|
||||
|
||||
The seed hypervisor development environment is supported for CentOS 8. 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
|
||||
Python virtual environment::
|
||||
|
||||
./dev/install-dev.sh
|
||||
|
||||
.. note::
|
||||
|
||||
This will create an :ref:`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 :ref:`contributor-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.
|
||||
|
||||
If using Ubuntu, configure the OS distribution::
|
||||
|
||||
sed -i -e 's/#os_distribution:/os_distribution: ubuntu/' config/src/kayobe-config/etc/kayobe/globals.yml
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
Run the ``dev/install-dev.sh`` script to install Kayobe and its dependencies in a
|
||||
Python virtual environment::
|
||||
|
||||
./dev/install-dev.sh
|
||||
|
||||

|
||||

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

|
||||
