VMS+Cobalt

Setup

1. Setup the vms_key.

• If you haven't bootstrapped your environment yet, you can add the VMS key via environments/Test-Laptop.json. Under bcpc create a key vms_key and fill it in with your download key.

• If you already have your environment, on the bootstrap node run:

  knife environment edit Test-Laptop
  

  And add vms_key under bcpc with your download key.

2. Re-run chef-client on all nodes.

Usage

1. Install the cobaltclient extensions.

• Via the apt repositories:

  # Install Gridcentric signing key
  wget -O - http://downloads.gridcentric.com/packages/gridcentric.key | sudo apt-key add -
  
  # Add Gridcentric repositories
  echo deb http://downloads.gridcentric.com/packages/cobaltclient/grizzly/ubuntu/ gridcentric multiverse | sudo tee -a /etc/apt/sources.list.d/cobaltclient.list
  
  # Update apt
  sudo apt-get update
  
  # Install the novaclient plugin for all users
  sudo apt-get install -y cobalt-novaclient
  

• Or via pip:

  # Install the novaclient plugin for the current user
  pip install --user cobalt_python_novaclient_ext
  

2. Install a suitable image.

There are a few issues with the CirrOS image.

You can easily add an Ubuntu 12.04 image as follows:

curl -O http://cloud-images.ubuntu.com/releases/precise/release/ubuntu-12.04-server-cloudimg-amd64-disk1.img
qemu-img convert -O raw ubuntu-12.04-server-cloudimg-amd64-disk1.img ubuntu-12.04-server-cloudimg-amd64-disk1.raw
glance image-create --name=ubuntu-12.04 --is-public=True --container-format=bare --disk-format=raw --file ubuntu-12.04-server-cloudimg-amd64-disk1.raw

3. Use it.

Example usage:

# Generate a keypair for instances.
ssh-keygen
nova keypair-add ubuntu --pub_key=~/.ssh/id_rsa.pub

# Boot a new instance the old-fashioned way.
nova boot --key_name ubuntu --image ubuntu-12.04 --flavor 1 --availability_zone=Test-Laptop instance-name

# Install the agent in the instance (for IP reconfig, etc.).
nova cobalt-install-agent --user ubuntu instance-name

# Create a new live image.
nova live-image-create instance-name live-image-name

# Launch a clone.
nova live-image-start --live-image live-image-name new-instance-name
