===== Propositions for Joid integration in CI =====

==== Prerequisites ====

=== Jenkins install ===

Please follow HOW TO here: https://wiki.opnfv.org/wiki/jenkins#how_to_connect_servers_from_labs_to_opnfv_jenkins

=== Jump host preparation ===

The jumphost must be a flavor of Ubuntu
The following things must be set on the jumphost before starting any deploy:

  * applications must be installed
    * ''git''
    * ''bridge-utils''
    * ''vlan''
  * The network must also be set to host 3 bridges (TO BE DISCUSSED)
    * ''brAdm''
    * ''brData''
    * ''brStorage''

All those pre-requisits can be managed by Master MAAS.

Now you can launch jenkins

===== Jenkins parameters =====

Jenkins fixes those parameters:

====Jenkins defaults====
<code>
# Slave name on Jenkins	
export SLAVE_NAME=orange-fr-pod2
export NODE_NAME=$SLAVE_NAME

# Git URL to use on this Jenkins Slave
export GIT_BASE=https://gerrit.opnfv.org/gerrit/$PROJECT

# Project Name
export PROJECT=joid

# Place of jenkins workspace
export WORKSPACE=$HOME/workspace/joid-deploy-<scenario>/
# in case of local script testing
export WORKSPACE=$HOME/joid/

</code>


====Projects default====

The file containing installer defaults is **releng/jjb/opnfv/installer-params.yml**
<code>
# IP of the installer (Not used for Joid)
export INSTALLER_IP=192.168.Y.Y

# Installer used for deploying OPNFV on this POD
export INSTALLER_TYPE=joid

# Scenario to deploy and test
# Based on scenario naming we can get joid options
# naming convention:
#    os-<controller>-<nfvfeature>-<mode>[-<extrastuff>]
# With parameters:
#    controller=(nosdn|odl_l3|odl_l2|onos|ocl)
#       No odl_l3 today
#    nfvfeature=(kvm|ovs|dpdk|nofeature)
#       '_' list separated.
#    mode=(ha|noha)
#    extrastuff=(none)
#       Optional field - Not used today
export DEPLOY_SCENARIO=none

# OpenStack release (kilo|liberty)	
export OS_RELEASE=liberty

# External network to create (name;type;first ip;last ip; gateway;network)	
export EXTERNAL_NETWORK="ext-net;flat;192.168.0.2;192.168.0.253;192.168.0.1;192.168.0.0/24"

# Disks to use by ceph by default (space separated list)	
export CEPH_DISKS=/srv

# Disks to use by ceph by controllers (empty if same as CEPH_DISKS)	
export CEPH_DISKS_CONTROLLERS=""

# Local lab config and Openstack openrc location	
export LAB_CONFIG=$HOME/joid_config

# Format or not disk before using ceph [true/false] (must be done the first time)	
export CEPH_REFORMAT=false

# Reinstall MAAS and Bootstrap before deploy [true/false]	
export MAAS_REINSTALL=false
</code>

==== Pod defaults====
The file containing pod default is **releng/jjb/opnfv/slave-params.yml**

<code>
# Version of the installer to deploy
export INSTALLER_VERSION=latest	
</code>

Those parameters shall be present in the pod default.
<code>
# Disks to use by ceph by default (space separated list)	
export CEPH_DISKS=/srv

# Disks to use by ceph by controllers (empty if same as CEPH_DISKS)	
export CEPH_DISKS_CONTROLLERS=/srv
</code>

===== Cleanup steps =====

The cleanup is done at each deploy in the script

===== HOW TO =====

==== Run CI deploy script without jenkins ====

  * Copy all jenkins parameters (see list 'Jenkins parameters' section) in a file (~/deploy_params.sh) and set them according to your platform (**don't forget to set DEPLOY_SCENARIO value !**)
  * Load this file
<code>source ~/deploy_params.sh</code>
  * Get the script
<code>wget https://git.opnfv.org/cgit/releng/plain/jjb/joid/joid-deploy.sh
chmod +x joid-deploy.sh</code>
  * Run the script
<code>./joid-deploy.sh</code>

==== Add my pod deployed by jenkins ====

  - Edit Releng **jjb/joid/joid-ci-jobs.yml**
     - to add your node to pod list in the project section
     - to add your trigger macro at the end of the file
  - Add your pod description in **jjb/opnfv/slave-params.yml**
  - Setup (or not) your local config file, as described in "Set specific pod parameters".
  - If your $POD_NAME is not formated like this: <POD_DATA_CENTER>-<POD_ID> as set in joid/ci/maas/<POD_DATA_CENTER>/<POD_ID> subfolders, please modify section "Set Joid pod config name" in **releng/jjb/joid/joid-deploy.sh**
  - Ask jenkins to deploy :)

==== Set specific pod parameters ====

The pod admin can set a few parameters

<code>
sudo -s jenkins
mkdir ~/joid_config
cat << EOF > ~/joid_config/config.sh
### Set passwords
export MAAS_USER=ubuntu
export MAAS_PASSWORD=ubuntu
export OS_ADMIN_PASSWORD=openstack
EOF
</code>

==== Deploy or not MAAS at each time ====

Testing MAAS deploy is not the core of CI tests, so to gain time, MAAS reinstall can be disabled by setting local parameter MAAS_REINSTALL=false. Juju will be cleaned and all nodes managed will return in ready mode.
