Roger Luethi 578c593607 labs: take additional snapshots of controller node
Take a snapshot of the controller VM after installing the compute and
network nodes.

The configuration of compute and network nodes is largely saved in the
database running on the controller node, but until now these database
changes were not part of any snapshots. With this changeset, resetting
all nodes to the most recent snapshots restores a working cluster.

Training Labs

About

Training Labs will provide scripts to automate the creation of the Training Environment.

Note: Training Labs are specifically meant for OpenStack Training and are specifically tuned as per Training Manuals repo.

Pre-requisite

How to run the scripts

  1. Clone the training-guides repo which contains scripts in the labs section that will install multi-node OpenStack automatically.

     $ git clone git://git.openstack.org/openstack/training-guides
    
  2. Go to the labs folder

     $ cd training-guides/labs
    
  3. Run the script:

     $ ./osbash -b cluster
    

This will do the complete installation for all the nodes - Controller, Compute and Network.

For more help you can check

    $ ./osbash --help

This will take some time to run the first time.

What the script installs

Running this will automatically spin up 3 virtual machines in VirtualBox:

  • Controller node
  • Network node
  • Compute node

Now you have a multi-node deployment of OpenStack running with the below services installed.

OpenStack services installed on Controller node:

  • Keystone

  • Horizon

  • Glance

  • Nova

    • nova-api
    • nova-scheduler
    • nova-consoleauth
    • nova-cert
    • nova-novncproxy
    • python-novaclient
  • Neutron

    • neutron-server
  • Cinder

Openstack services installed on Network node:

  • Neutron

    • neutron-plugin-openvswitch-agent
    • neutron-l3-agent
    • neutron-dhcp-agent
    • neutron-metadata-agent

Openstack Services installed on Compute node:

  • Nova

    • nova-compute
  • Neutron

    • neutron-plugin-openvswitch-agent

How to access the services

There are two ways to access the services:

  • OpenStack Dashboard (horizon)

You can access the dashboard at: http://192.168.100.51/horizon

Admin Login:

Username: admin

Password: admin_pass

Demo User Login:

Username: demo

Password: demo_pass

  • SSH

You can ssh to each of the nodes:

    $ ssh controller@10.10.10.51

    $ ssh compute@10.10.10.51

    $ ssh network@10.10.10.51

Credentials for all nodes:

Username: osbash

Password: osbash

After you have ssh access, you need to source the OpenStack credentials in order to access the services.

Two credential files are present on each of the nodes: demo-openstackrc.sh admin-openstackrc.sh

Source the following credential files

For Admin user privileges:

    $ source admin-openstackrc.sh

For Demo user privileges:

    $ source demo-openstackrc.sh

Now you can access the OpenStack services via CLI.
