Metal³ Ansible installer

This set of playbooks provides an unattended installation of dev-scripts on a local or remote system. This is useful for automatic deployments, setting up a development environment, or demonstrating Metal³ complete with the kubevirt/web-ui.

This is very similar to how we do TripleO testing so we reuse some roles from tripleo-quickstart here.

By default, this will deploy 'master' branches of each component, but can be modified given the options pointed out below.

Additional information regarding the details and specifics of the deployment can be found in the dev-scripts documentation.

Pre-requisites

• CentOS 7.5 or greater (installed from 7.4 or newer)
• file system that supports d_type (see Troubleshooting section for more information)
• ideally on a bare metal host
• run as a user via ssh with passwordless sudo access to a remote system
• get a valid pull secret (json string) from https://cloud.openshift.com/clusters/install#pull-secret

Instructions

Configuration

Edit group_vars/all.yml to your liking. The only mandatory default is that of 'pull_secret'; these are necessary to properly pull down containers that are required for dev-scripts

Other notable options are:

• rhhi_user
• dev_scripts_dir
• dev_scripts_refspec
• web_ui_refspec
• go_path

Installation

For a new setup, run:

./dev-scripts.sh <remote host>

The script will run playbooks that each represents dev-scripts scripts. The following scripts will run in order:

• 01_install_requirements.sh
• 02_configure_host.sh
• 03_ocp_repo_sync.sh
• 04_setup_ironic.sh
• 06_create_cluster.sh
• 08_deploy_bmo.sh
• 11_register_hosts.sh

An additional playbook will start kubevirt/web-ui, both with the authentication bridge and the Yarn development server.

The deployment is idempotent; it can be re-ran against a system which already has a dev-scripts deployment on it. The previous dev-scripts deployment will be make clean'ed and a new deployment will be made.
