Flamenco 2.0

Development repo for Flamenco 2.0 (originally known as brender). Flamenco is a Free and Open Source Job distribution system for render farms.

Warning: currently Flamenco is in beta stage, testing welcome!

Developer installation

In order to install Flamenco, we recommend to set up a Python virtual environment.

$ sudo easy_install virtualenv

On Linux this might work better:

$ sudo apt-get install python-virtualenv

Once you have virtualenv installed, just fire up a shell and create your own environment. You may want to create this folder inside of the Flamenco folder:

$ cd Flamenco
$ virtualenv venv
New python executable in venv/bin/python
Installing distribute............done.

Now, whenever you want to work on a project, you only have to activate the corresponding environment. On OS X and Linux, do the following:

$ . venv/bin/activate

Now you can just enter the following command to get Flask activated in your virtualenv:

Core dependencies

The project has been developed for python2.7. We will move to python3 eventually.

On Unix systems, to install python dependencies, you may need to install python-dev package.

On OSX, in order to prevent some warnings, you might need to run:

$ ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

Then we just install all the packages required (run this on all systems)

$ pip install -r requirements.txt

Databases are managed by MySQL or SQLite (for testing only, don't use in production).

Grunt file for the Dashboard

In order to streamline UI development of the Dashboard, we use Jade templating and Sass for the CSS generation. In oder to generate the templates and CSS needed by the dashboard, you need to install NodeJS and run the following commands.

OSX

cd flamenco/dashboard
npm install -g grunt-cli
npm install
grunt

Debian Linux Wheezy and Ubuntu 14.04

sudo aptitude install python3-pip libmysqlclient-dev build-essential python-dev libjpeg8 libjpeg8-dev libfreetype6 libfreetype6-dev zlib1g-dev python-pip

sudo pip install virtualenv
# install blender BAM using pip3
sudo pip3 install blender-bam

# install python deps (remember to `source bin/activate` first!)
pip install -r $FLAMENCODIR/requirements.txt

# dashboard dependencies
cd flamenco/dashboard

# this is needed only on wheezy distribution
sudo echo "deb http://ftp.us.debian.org/debian wheezy-backports main" >> /etc/apt/sources.list
sudo apt-get update

# On linux you can install NodeJS using the package manager.
sudo apt-get install nodejs nodejs-legacy curl
sudo curl -L --insecure https://www.npmjs.org/install.sh | bash
sudo npm install -g grunt-cli
sudo apt-get install ruby
sudo gem install sass
sudo npm install
grunt

Running Flamenco

It's pretty simple. Move into each folder ( server, manager, dashboard, worker) and run:

$ ./manage.py runserver # will start the different components

When running this command for the Manager for the first time, you will be prompted for some configuration parameters.

If you now visit http://localhost:8888 with your web browser you should see the dashboard!

It is also possible to configure the different applications. You may find a config.py.example, so you can rename it to config.py and edit it before run the application.

Architecture

The important subfolders are:

• server containing the server files
• worker containing the worker files (render nodes)
• manager containing the manager files (manage clusters)
• dashboard containing the dashboard (web interface to talk to the server)

This structure explains also the naming conventions adopted to distinguish the different parts of Flamenco. Each folder contains an individual Flask application (except for the worker). Server, Manager and Worker exchange JSON formatted messages between each other via a REST API. Dashboard connects to the Server only and accepts connections from clients (Browsers).

About the web interface

Frameworks and tools used by the interface are:

• jQuery
• Bootstrap
• DataTables

User and Developer documentation

The documentation is built with Sphinx and uses the readthedocs.org theme, so make sure you have it installed. Instructions are available here:

https://github.com/snide/sphinx_rtd_theme

The _build contains the locally compiled documentation, which does not need to be committed to the branch.
