Download and Installation
The following steps capture how to install valence. All installation steps require super user permissions.
Database etcd installation
Single node installation reference: https://github.com/coreos/etcd/releases
Distributed installation reference: https://github.com/coreos/etcd/blob/master/Documentation/op-guide/clustering.md
For development, single node installation is recommended practice.
Valence installation
Install software dependencies
$ sudo apt-get install git python-pip python-dev build-essentialClone the Valence code from git repo.
$ git clone https://git.openstack.org/openstack/valenceExecute the 'install_valence.sh' file present in the Valence root directory. The install script will automatically install the dependencies listed in the requirements.txt file.
$ sudo bash install_valence.shCheck the values in valence.conf located at /etc/valence/valence.conf
set the ip/credentials of podm for which this Valence will interactCheck the PYTHON_HOME and other variables in /etc/init/valence.conf
Initialize etcd database
$ valence-db-manager initNote: The TypeError exception "TypeError: NoneType object is not callable" is caused by known python-etcd bug, which will not impact this db init functionality. https://github.com/jplana/python-etcd/issues/190
Start valence service
$ sudo service valence startLogs are located at /var/logs/valence/
GUI installation
Please refer to the installation steps in the ui/README file.
Components
Valence follows the typical OpenStack project setup. The components are listed below:
valence-api
A python based daemon based on Flask framework to expose Valence REST APIs. The api service communicates to the PODM through REST interface using Redfish(TM) specification. For adding new api please refer https://github.com/openstack/valence/blob/master/doc/source/developer-guide/add_new_api.rst
valence-ui
valence-ui provides a Web-based GUI interface that can be used to explore Rack Scale Design (RSD) artifacts and compose/disassemble nodes. valence-ui is implemented using Node.js runtime environment and hosted through apache. valence-ui makes us of React.js javascript libaray and invoke Valence REST APIs through ajax REST calls.
Features
Please refer the Valence blueprints for supported and in-the-pipeline
features.
