Valence is a service for lifecycle management of pooled bare-metal hardware infrastructure such as Intel(R) Rack Scale architecture which uses Redfish(TM) as one of the management protocols.

The following steps capture how to install valence. All installation steps require super user permissions.

1. Install software dependencies

   $ sudo apt-get install git python-pip rabbitmq-server libyaml-0-2 python-dev

2. Configure RabbitMq Server

   $ sudo rabbitmqctl add_user rsd rsd #user this username/pwd in valence.conf

   $ sudo rabbitmqctl set_user_tags rsd administrator

   $ sudo rabbitmqctl set_permissions rsd ".*" ".*" ".*"

3. Clone the Valence code from git repo and change the directory to root Valence folder.

4. Install all necessary software pre-requisites using the pip requirements file.

   $ sudo -E pip install -r requirements.txt

5. Execute the 'install_valence.sh' file the Valence root directory.

   $ ./install_valence.sh

6. Check the values in valence.conf located at /etc/valence/valence.conf

   set the ip/credentials of podm for which this Valence will interact

   set the rabbitmq user/password to the one given above(Step 2)

7. Check the values in /etc/init/valence-api.conf, /etc/init/valence-controller.conf

8. Start api and controller services

   $ service valence-api start

   $ service valence-controller start

9. Logs are located at /var/logs/valence/

Please refer to the installation steps in the ui/README file.

Valence follows the typical OpenStack project setup. The components are listed below:

A pecan based daemon to expose Valence REST APIs. The api service communicates to the controller through AMQP.

The controller implements all the handlers for Plasma-api. It reads requests from the AMQP queue, process it and send the reponse back to the caller.

valence-ui provides a GUI interface to invoke Valence APIs.
