====== Fuel Build and Install instructions ======

How to setup and use the OPNFV/BGS/FUEL build system.  This is a work in progress, find the latest revision in genesis DOC/README.build and README.install 

===== 1. Build system requirements =====

==== 1.1 Host HW/VM requirements ====
- A x86_64 host (real iron or VM) with Ubuntu 12.04/14.04 LTS installed
- 100 GB storage
- 8 GB RAM

==== 1.2 Host SW dependencies ====
On the host, the following packages must be installed:
- docker - see https://docs.docker.com/installation/ubuntulinux/ for installation notes for 12.04 and 14.04
- git (simply available through apt-get install git)

===== 2 Setting up the Docker build container =====
When having installed Docker, add yourself to the docker group:
  usermod -a -G docker <userid>

Also make sure to define relevant dns servers part of the global dns chain in
in your /etc/default/docker config file, eg.
  DOCKER_OPTS=" --dns=8.8.8.8 --dns=8.8.8.4"

Then restart docker with "service docker restart".:

===== 3. Setting up OPNFV Gerrit in order to being able to clone the code =====
Start by creating a SSH key, if you don't already have one, create one with 
  ssh-keygen

Add your generated public key in OPNFV Gerrit -https://gerrit.opnfv.org/
  (this requires a linuxfoundation account, create one if you do not already have one)

Select "SSH Public Keys" to the left and then "Add Key" and paste your public key in.

===== 4. Clone the OPNFV code git repository =====
So now we're coming to the fun part! Let's clone the code repository:
  git clone ssh://<Linux foundation user>@gerrit.opnfv.org:29418/genesis

Change the directory to "fuel-build"
  cd fuel-build/

===== 5. Set up (build) your build environment =====
YOU DO NOT NEED TO SET UP YOUR BUILD ENVIRONMENT, THE TOP MAKE ALL TARGET WILL DO THAT FOR YOU IF NOT ALREADY DONE,
THE BELOW ACTIONS IN THIS SECTION ARE NOT NEEDED!

//Note and TODO:
The build system will for now partly run as sudo as that is needed for the debootstrap procedure to create the root file
system for the Ubuntu 12.04 Docker image - BUT NOTE, NONE OF THE MAKEFILES OR SCRIPTS SHALL BE EXECUTED WITH SUDO/ROOT PRIVILEDGES!
(TODO: Change the scripts so that no root priviledges will be needed)

With your ordinary user-, run the following commands from your git root:
cd docker
make (and you will be prompted for your password by sudo)
cd ..
//
===== 6. Build your fuel .iso image =====
That's it, time to build!
  make [all]

This will:
I * f not allready existing, initialize the docker build environment
  * If not already done, build fuel from upstream
  * Build the defined derivate of fuel (as defined by the structure of this framework)

If the build is successful, you will find the generated ISO file in the release subdirectory!
----
Now the tricky part - to deploy.  This is under development and will be scripted in more detail.

=============================================================
====== 7. Install Fuel Server ======

1. Mount the built .iso file (release/opnfv-<version>.iso) as a bootdevice to the fuel server.

2. Reboot the fuel server.
   The system now boots from the ISO image.

3. Change the grub boot params
   When Press Tab to edit . is shown press Tab.
   Change showmenu=no to showmenu=yes.
   Change netmask=255.255.255.0 to netmask=255.255.0.0.
   Press Enter.

4  Wait until screen Fuel setup . is shown.
   Note: This takes about 30 minutes.

5. Select PXE Setup and change the following fields to appropriate values (example below):
   Static Pool Start 10.20.0.3
   Static Pool End 10.20.0.254
   DHCP Pool Start 10.20.128.3
   DHCP Pool End 10.20.128.254

6. Select DNS & Hostname and change the following fields to appropriate values:
   Hostname <CEE Region name>-fuel
   Domain <Domain Name>
   Search Domain <Search Domain Name>
   Hostname to test DNS <Hostname to test DNS>

7. Select Time Sync and change the following fields to appropriate values:
   NTP Server 1 <Customer NTP server 1>
   NTP Server 2 <Customer NTP server 2>
   NTP Server 3<Customer NTP server 3>
   Note: This step is only to pass the network test, the actual ntp parameters will be set with the pre_deply script.

8. Start the installation.
   Select Quit Setup and press Save and Quit.
   Installation starts, wait until a screen with logon credentials is shown.
   Note: This takes about 15 minutes.

10. Enable PXE Booting and put it first in the bios boot order menu.

11. Reboot the controller- and compute blades.

12. Connect to Fuel wit a browser towards port 8000

13. Create and name a new OpenStack environment, to be installed.

14. Select Icehouse on Ubuntu . in field OpenStack Release.

15. Select deployment mode.
    Select the Multi-node with HA.

16. Select compute node mode.
    Select KVM as hypervisor.

17. Select network mode.
    Select Neutron with VLAN segmentation.

18. Select Storage Backends.
    Select Ceph for Cinder and default for glance.


19. Select additional services.
    Check option Install Celiometer (OpenStack Telemetry).

20. Create the new environment.

    Check nodes to be installed as Compute nodes in pane Assign Role.
    Click Apply Changes.

34. Configure interfaces.
    Check Select All to select all nodes with Control, Telemetry . MongoDB and Compute node roles.
    Click Configure Interfaces.
    Screen Configure interfaces on number of <number of nodes> nodes is shown.
