CloudKitty installation and configuration

Install from source

There is no release of CloudKitty as of now, the installation can be done from the git repository.

Retrieve and install CloudKitty:

git clone git://git.openstack.org/openstack/cloudkitty
cd cloudkitty
python setup.py install

This procedure installs the cloudkitty python library and a few executables:

• cloudkitty-api: API service
• cloudkitty-processor: Processing service (collecting and rating)
• cloudkitty-dbsync: Tool to create and upgrade the database schema
• cloudkitty-storage-init: Tool to initiate the storage backend
• cloudkitty-writer: Reporting tool

Install sample configuration files:

mkdir /etc/cloudkitty
cp etc/cloudkitty/cloudkitty.conf.sample /etc/cloudkitty/cloudkitty.conf
cp etc/cloudkitty/policy.json /etc/cloudkitty

Install from packages

Packages for RHEL/CentOS 7 and Ubuntu 14.04 are available for the Kilo release.

For RHEL/CentOS 7

1. Enable the EPEL and RDO repositories for Kilo:

yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
yum install http://rdo.fedorapeople.org/openstack-kilo/rdo-release-kilo.rpm

1. Create the /etc/yum.repos.d/cloudkitty.repo configuration file to enable the CloudKitty repository:

[cloudkitty]
name=CloudKitty repository (Kilo)
baseurl=http://archive.objectif-libre.com/cloudkitty/el7/kilo/
gpgcheck=1
gpgkey=http://archive.objectif-libre.com/ol.asc

1. Install the packages:

yum install cloudkitty-api cloudkitty-processor cloudkitty-dashboard

For Ubuntu 14.04

1. Enable the Canonical cloud-archive repository for the Kilo release:

apt-get install ubuntu-cloud-keyring
echo "deb http://ubuntu-cloud.archive.canonical.com/ubuntu trusty-updates/kilo main" > \
    /etc/apt/sources.list.d/cloudarchive-kilo.list

1. Install the CloudKitty repository public key and configure apt:

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 71E414B3
echo 'deb http://archive.objectif-libre.com/cloudkitty/ubuntu trusty/kilo main' > \
    /etc/apt/sources.list.d/cloudkitty-kilo.list
apt-get update

1. Install the packages:

apt-get install cloudkitty-api cloudkitty-processor cloudkitty-dashboard

Configure CloudKitty

Edit /etc/cloudkitty/cloudkitty.conf to configure CloudKitty.

The following shows the basic configuration items:

[DEFAULT]
verbose = True
log_dir = /var/log/cloudkitty

[oslo_messaging_rabbit]
rabbit_userid = openstack
rabbit_password = RABBIT_PASSWORD
rabbit_hosts = RABBIT_HOST

[auth]
username = cloudkitty
password = CK_PASSWORD
tenant = service
region = RegionOne
url = http://localhost:5000/v2.0

[keystone_authtoken]
username = cloudkitty
password = CK_PASSWORD
project_name = service
region = RegionOne
auth_url = http://localhost:5000/v2.0
auth_plugin = password

[database]
connection = mysql://cloudkitty:CK_DBPASS@localhost/cloudkitty

[keystone_fetcher]
username = admin
password = ADMIN_PASSWORD
tenant = admin
region = RegionOne
url = http://localhost:5000/v2.0

[ceilometer_collector]
username = cloudkitty
password = CK_PASSWORD
tenant = service
region = RegionOne
url = http://localhost:5000

Setup the database and storage backend

MySQL/MariaDB is the recommended database engine. To setup the database, use the mysql client:

mysql -uroot -p << EOF
CREATE DATABASE cloudkitty;
GRANT ALL PRIVILEGES ON cloudkitty.* TO 'cloudkitty'@'localhost' IDENTIFIED BY 'CK_DBPASS';
EOF

Run the database synchronisation scripts:

cloudkitty-dbsync upgrade

Init the storage backend:

cloudkitty-storage-init

Setup Keystone

CloudKitty uses Keystone for authentication, and provides a rating service.

To integrate CloudKitty to Keystone, run the following commands (as OpenStack administrator):

keystone user-create --name cloudkitty --pass CK_PASS
keystone user-role-add --user cloudkitty --role admin --tenant service

Give the rating role to cloudkitty for each tenant that should be handled by CloudKitty:

keystone role-create --name rating
keystone user-role-add --user cloudkitty --role rating --tenant XXX

Create the rating service and its endpoints:

keystone service-create --name CloudKitty --type rating
keystone endpoint-create --service-id RATING_SERVICE_ID \
    --publicurl http://localhost:8888 \
    --adminurl http://localhost:8888 \
    --internalurl http://localhost:8888

Start CloudKitty

Start the API and processing services:

cloudkitty-api --config-file /etc/cloudkitty/cloudkitty.conf
cloudkitty-processor --config-file /etc/cloudkitty/cloudkitty.conf

Horizon integration

Retrieve and install CloudKitty's dashboard:

git clone git://git.openstack.org/openstack/cloudkitty-dashboard
cd cloudkitty-dashboard
python setup.py install

Find where the python packages are installed:

PY_PACKAGES_PATH=`pip --version | cut -d' ' -f4`

Then add the enabled file to the horizon settings or installation. Depending on your setup, you might need to add it to /usr/share or directly in the horizon python package:

# If horizon is installed by packages:
ln -s $PY_PACKAGES_PATH/cloudkittydashboard/enabled/_[0-9]*.py \
/usr/share/openstack-dashboard/openstack_dashboard/enabled/

# Directly from sources:
ln -s $PY_PACKAGES_PATH/cloudkittydashboard/enabled/_[0-9]*.py \
$PY_PACKAGES_PATH/openstack_dashboard/enabled/

Restart the web server hosting Horizon.
