Development repo for flamenco 2.0 (originally known as brender). Flamenco is a Free and Open Source Job distribution system for render farms.
Warning: we are going to stay in alpha stage until the end of February 2015.
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:
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 should first run:
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.
Psutil is needed for gathering system usage/performance stats on the worker. Ideally psutil is needed only on the workers.
First you need to initialize the server and manager's databases:
$ cd server; ./manage.py db upgrade $ cd manager; ./manage.py db upgrade
It's pretty simple. Move into each node folder and run - in four different terminals:
$ ./manage.py runserver # will start the node (dashoard, server, manager or worker according to the current folder)
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.
At the moment we are still using the original brender folder, which will be renamed soon. 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. 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).
Frameworks and tools used by the interface are:
Most of this document will be migrated into the docs folder, alongside with the user documentation.
The documentation is made with Sphinx and uses the readthedocs.org theme, so make sure you have it installed. Instructions are available here:
The _build contains the locally compiled documentation, which does not need to be committed to the branch.
