Deploy Cloudkitty

OpenStack Cloudkitty is the rating and chargeback service for OpenStack helps operators measure, rate, and bill tenants (projects) for the resources they consume in an OpenStack cloud. This document outlines the deployment of OpenStack Cloudkitty using Genestack.

Create secrets

Information about the secrets used

Manual secret generation is only required if you haven't run the create-secrets.sh script located in /opt/genestack/bin.

Example secret generation

kubectl --namespace openstack \
        create secret generic cloudkitty-rabbitmq-password \
        --type Opaque \
        --from-literal=username="cloudkitty" \
        --from-literal=password="$(< /dev/urandom tr -dc _A-Za-z0-9 | head -c${1:-64};echo;)"
kubectl --namespace openstack \
        create secret generic cloudkitty-db-password \
        --type Opaque \
        --from-literal=password="$(< /dev/urandom tr -dc _A-Za-z0-9 | head -c${1:-32};echo;)"
kubectl --namespace openstack \
        create secret generic cloudkitty-admin \
        --type Opaque \
        --from-literal=password="$(< /dev/urandom tr -dc _A-Za-z0-9 | head -c${1:-32};echo;)"

Tip

You may need to provide custom values to configure your OpenStack services. For a simple single region or lab deployment you can supply an additional overrides flag using the example found at base-helm-configs/aio-example-openstack-overrides.yaml.

Validate functionality

kubectl --namespace openstack exec -ti openstack-admin-client -- openstack rating module list
