Test openstack-ansible multi-node using cloud instances

0-setup-procedure.sh

# Ensure that your cloud account has an ssh key configured
# which you are prepared to use on an instance in the cloud.

# Create network for inter-host communication:
# name: 'internal-net'
# CIDR: '192.168.3.0/24'

# Create instances for your environment (make sure that the extra network is selected):
# infra1
#   g1-8 flavor (8CPU, 8RAM, 160GB HDD)
#   Ubuntu 14.04 LTS PVHVM image
# compute1
#   g1-8 flavor (8CPU, 8RAM, 160GB HDD)
#   Ubuntu 14.04 LTS PVHVM image
# storage1
#   g1-8 flavor (8CPU, 8RAM, 160GB HDD)
#   Ubuntu 14.04 LTS PVHVM image

# SSH to the public IP address for infra1

###
### Prepare infra1 as the deployment host
###
# This section matches to this part of the docs:
# http://docs.openstack.org/developer/openstack-ansible/install-guide/deploymenthost.html
# There are some extra bits here due to running this test in cloud instances.

# Install git and some other bits
apt-get update && \
  apt-get purge -y nano && \
  apt-get install -y git vim tmux fail2ban

# Enter a tmux session
tmux new

# If you lose connection, just ssh back to the
# instance and execute the following to reattach
# to the same session.
# tmux attach

# Setup the various variables and git settings to
# allow you to download patches from gerrit.
git config --global user.email "<your email address>"
git config --global user.name "<your name>"
git config --global push.default matching
git config --global --add gitreview.username "<your gerrit username>"

# Set up the ssh keys which will allow you to access
# all the instances.
mkdir -p ~/.ssh
vi ~/.ssh/id_rsa # copy your ssh private key contents into this file
vi ~/.ssh/id_rsa.pub # copy your ssh public key contents into this file
chmod -R 700 ~/.ssh

# Prepare a bootstrapping inventory for the instances.
# Make sure to replace <public ip address> with each instance IP address.
# Put the file (located near the bottom of this gist) into the root home directory.
# file name: '~/inventory.ini'

# Create a playbook to execute the bootstrap-host role against
# the instances in order to prepare their networking.
# Put the file (located near the bottom of this gist) into the root home directory.
# file name: '~/bootstrap-hosts.yml'

# Clone the openstack-ansible repository.
git clone https://github.com/openstack/openstack-ansible.git /opt/openstack-ansible
cd /opt/openstack-ansible

# Set the role clone method to use git. (optional step)
# This is to allow patches to be applied if need be.
export ANSIBLE_ROLE_FETCH_MODE="git-clone"

# Setup ansible for openstack-ansible usage
./scripts/bootstrap-ansible.sh

###
### Prepare the target hosts
###
# This section matches to this part of the docs:
# http://docs.openstack.org/developer/openstack-ansible/install-guide/targethosts-prepare.html

# Execute the bootstrap playbook against your environment.
# This takes care of all host bootstrapping, so you don't have to. :)
cd tests
ansible-playbook -i ~/inventory.ini ~/bootstrap-hosts.yml

###
### Prepare the OpenStack-Ansible configuration
###
# You can now continue through the documentation:
# http://docs.openstack.org/developer/openstack-ansible/install-guide/configure.html
