Freva, the free evaluation system framework, is a data search and analysis platform developed by the atmospheric science community for the atmospheric science community. With help of Freva researchers can:

  • quickly and intuitively search for data stored at typical data centers that host many datasets.

  • create a common interface for user defined data analysis tools.

  • apply data analysis tools in a reproducible manner.

Data analysis is realised by user developed data analysis plugins. These plugins are code agnostic, meaning that users don’t have to rewrite the core of their plugins to make them work with Freva. All that Freva does is providing a user interface for the plugins.

Currently Freva comes in three different flavours:

  • a python module that allows the usage of Freva in python environments, like jupyter notebooks

  • a command line interface (cli) that allows using Freva from the command lines and shell scripts.

  • a web user interface (web-ui)

This documentation gives an overview over the installation process of Freva as well as it’s configuration, maintenance and administration. It mainly covers the deployment process and the usage of a dedicated deployment software that was tailored to make the installation process of Freva somewhat more simple.

Because Freva is a software that is meant to run on HPC type distributed systems this documentation first gives an overview of various deployment strategies. After this section a basic configuration that is necessary to make the different components of Freva work with each other is introduced. This is followed by a documentation on how to install the Freva deployment software. After this section basic deployment setup and servicing Freva will be introduced.
