Create an OpenStack framework for running a multicluster IPA setup

Overview

Create a simple site & clusters setup on OpenStack consisting of:

• A site
  • Controller node (to be used as a centralised IPA server)
    • controller1.SITENAME.alces.network
  • Network (all clusters launched within this)
• Multiple clusters
  • Login node
    • login1.CLUSTERNAME.SITENAME.alces.network
  • Multiple compute nodes

The site controller will have passwordless root SSH access to the login nodes of the clusters.

To Do

• Add web interface
  • Embedded terminal for useradmin to add new users
  • Login API for regular cluster users which allows redirecting to cluster Web Suites
• Add Flight Solo integration for adding to domain

Launching

• Ensure config options in settings.sh look correct
• Create a site

  bash create-site.sh mysite

• Create a cluster (manually increment the SUBNET_COUNT in sites/mysite.sh for subsequent clusters)

  bash create-cluster.sh mysite cluster1

Configuring

IPA Server

The script setup_scripts/ipa_server.sh will do all the server configuration, edit the variables to match your configuration first.

After the server is setup, the script setup_scripts/ipa_add_cluster.sh can be used to add the basic cluster information and a test user to the IPA server, edit the variables to match your configuration first.

Once a cluster is added then the hosts can be added with setup_scripts/ipa_add_host.sh. Edit the variables to match your configuration first.

Setup Flight Directory for doing CLI user management with setup_scripts/install_flight_directory.sh. Same warning you must have read 3 times already.

IPA Client

After doing the above, the script setup_scripts/ipa_client.sh will do all the client configuration. Edit the variables to match your configuration first.
