osp-deploy

Automates the Red Hat OpenStack Platform 13 process

  • Provisions a Director Node on Metal or within a VM
  • Prepares and configures the Undercloud
  • Introspects nodes
  • Deploys the Overcloud

Provisioning a Director VM

Start with a base install of RHEL or CentOS and configure it to be a Virtualization Host. This will provision the director node as a VM (TODO, add ability to skip and change inventory for Physical Server deployment):

If the kickstart to provision the host wasn't set up with virtualization support, install these packages and reboot:

yum -y install libvirt-client libvirt-daemon qemu-kvm libvirt-daemon-driver-qemu libvirt-daemon-kvm virtinstall bridge-utils rsync virt-viewer libvirt git

Check out osp-deploy

git clone https://gitlab.com/antonym/osp-deploy.git /opt/osp-deploy
cd /opt/osp-deploy

Setup Host Networking

We will need to make sure to have bridges available and up in the NIC configs. They can also be simulated for testing (ex. brcrl addbr bridge_name):

  • br-ctlplane
  • br-ex
  • br-ipmi

Virtualized Director

If you are virtualizing the director, the following command will add the necessary packages, download the latest RHEL 7.7 ISO and setup a director VM. If you are deploying director to a baremetal RHEL OS, you can skip this step and start with the next step.

./prepare_vm.sh

It will prompt for root and stack passwords and then provision the director VM.

Provision the Undercloud

Modify group_vars/undercloud.yml for undercloud overrides, anything set in undercloud.conf:

./deploy_director.sh

It will prompt for RHEL credentials so that the VM can registered and packages can be downloaded.

Prepare the Overcloud

  • modify group_vars/all.yml settings
  • generate a new playbooks/files/instackenv.json for hosts

This will prep the steps necessary for Overcloud deployment including Introspection:

./prepare_overcloud.sh

Provision the Overcloud (Under Development, recommend generating templates by hand)

  • modify overcloud_templates for environment, this directory is copied to /home/stack/templates and used for
./deploy_overcloud.sh

The script will copy all of the template files and create a deploy script on the director node. Then you'll log into the director node and kick off the overcloud deploy.

ssh stack@director
cd scripts
./deploy_overcloud.sh

Contributing and Merge Request Validation

Merge requests are tested with a sample deployment that simulates provisioning of the Director VM, undercloud deployment, and overcloud deployment. This ensures future changes don't break the existing deployment.

TODO

  • Automate networking template generation, or make it easier to generate based on deploy scenario
  • Automate SSL Cert generation and options, currently using a self signed
  • Move settings to a better template/config structure that can be extracted out for a seperate configuration repo per environment
  • Move to specifiying template directory to avoid having to use config file naming in the deploy_overcloud template.
  • Add configuration capture script for capturing working config and making a config repo that can then be deployed.
  • Add support for multiple versions outside of OSP 13
  • Cleanup
