Openstack Mitaka setup on single node (Ubuntu/Debian):
######################################################

1) Components that will be installed for the openstack setup in our environment.

	a) keystone
	b) glance
	c) nova
	d) neutron
	e) dashboard

2) For mysql, rabbitmq and memcache, we are using localhost IP address/domain (127.0.0.1/localhost).

3) Endpoints for all the services are created on localhost name. Ex: http://localhost:35357

4) For bridge use any one of the interface Ex: eth0/enp0s3 (provider), assign proper interface array number in group_vars/all file
	Ex: controller_interface:

5) This code is tested successfully on Debain machines.

6) Pre-required checks:
	a) Install Ubuntu/Debian server OS on Virtual server/ Physical server.
	b) Make sure that you have atleast one NIC interface/vboxnet (Management IP: eth0/enp0s3) for the server.
	c) Minimum of 4GB RAM and 60GB HDD.

How to run the playbook:
########################

	a) Add the following entries according to your environment.
		1) update the hosts file with the server hostname
		2) change the group_vars/all file accordingly, like admin password, users password etc.,
		3) group file is password protected (test123)
Note: Place the playbook code ( ansible.cfg, hosts, group_vars, roles etc) under /etc/ansible directory after removing the detault files.

	b) Copy the public of the ansible user to the node on which you will install Openstack.
		ssh-keygen (to create keypair) and ssh-copy-id user@<ip/hostname> (copy the public key to remote server/local)

	c) Execute the following command to check the connectivity from ansible server to Openstack node.
		ansible all -m ping  --> If this step is successfull, then execute the site.yml playbook

	d) check the syntax of the ansible code which you have downloaded.
		ansible-playbook site.yml --syntax-check

	e) Now, run the playbook site.yml which will install from basic components like repo, database, etc to dashboard.
		ansible-playbook site.yml

	f) If you facing issue while executing the above playbook, run playbook individually.
		Ex: ansible-playbook playbook/deploy_basic.yml

		---
		- include: playbooks/deploy_basic.yml
		- include: playbooks/deploy_database.yml
		- include: playbooks/deploy_rabbitmq.yml
		- include: playbooks/deploy_memcached.yml
		- include: playbooks/deploy_keystone.yml
		- include: playbooks/deploy_glance.yml
		- include: playbooks/deploy_nova.yml
		- include: playbooks/deploy_newtron.yml
		- include: playbooks/deploy_dashboard.yml

	g) after successfull installation, access the openstack dashborad with the ipaddress/dashboard from your browser.
