Homework Review

- Sets variables required for Glance deployment- Creates an Glance Service and Endpoint in

Keystone- Updates MySQL

- Creates a Glance DB- Assigns the Glance User to the DB

- Installs Glance- Configures Glance settings

- Verifies successful install- Uploads two image files

Build – What’s it doing?

- VM Image Management Service- Provides centralized source of VM images for

the OpenStack Compute (Nova) nodes- … Let’s take a look:

List Endpoints

For next week, our OpenStack deployment will increase from one to two servers when we introduce the Compute (Nova) Service. A Production OpenStack deployment typically consists of multiple Compute nodes to run the Cloud workloads.

We will need perform a few extra actions than we have done for the previous sessions:1. Edit the Vagrantfile to generate two servers instead of just one, and call the

second node “compute” (Hint: you may need to change the “nodes” Ruby Hash at the top of the file)

2. Any additional server that we create should have its own shell script file with its hostname as the filename (ex: compute.sh). At a minimum, automate the install of the following Ubuntu packages:

a. nova-api-metadata, nova-compute, nova-compute-qemu, nova-doc, nova-network, libvirt-bin, pm-utils

3. The controller.sh will need to be extended to create a nova database, an endpoint, service, etc. Also, the following Ubuntu packages need to be installed on the Controller:

a. rabbitmq-server, nova-api, nova-scheduler, nova-objectstore, dnsmasq, nova-conductor

Additionally, like getting glance up and running, let’s try to get compute installed and running on our own for next week.

Homework!
