Testing PYBOSSA with Vagrant¶
Vagrant is an open source solution that allows you to create and configure lightweight, reproducible, and portable development environments.
Vagrant simplifies a lot setting up all the requirements for a web application like PYBOSSA, as you will set up a virtual machine that automagically downloads all the required libraries and dependencies for developing and testing the project.
For these reasons, PYBOSSA uses Vagrant to allow you to start effortlessly hacking the system, and more importantly, without polluting your system with lots of libraries that you may or may not needed (everything is configured in the Virtual Machine, which is a very safe sand-box!).
Additionally, several cloud companies have integration with Vagrant, so deploying a PYBOSSA server is simple using this method.
The virtual machine and server have a basic security set of rules (passwords, secrets, firewall, etc.). Therefore, if you are going to use this method to deploy a PYBOSSA production server it is your responsibility to secure the system properly.
Setting up PYBOSSA with Vagrant¶
To start using Vagrant and PYBOSSA all you have to do is installing the following open source software:
Clone the PYBOSSA git repository (be sure to install git in your machine!):
git clone --recursive https://github.com/Scifabric/pybossa.git
Once you have downloaded the source code, all you have to do to start your PYBOSSA development environment is typing the following in a terminal:
cd pybossa vagrant up
The system will download a Virtual Machine, install all the required libraries for PYBOSSA and set up the system for you inside the virtual machine.
Vagrant is great because all the changes that you will make in your local copy of PYBOSSA will be automatically populated to the Virtual Machine. Hence, if you add a new feature to the system, you will be able to test it right away (this feature is pretty handy for workshops, hackfests, etc.).
Running the PYBOSSA server¶
Now that all the libraries and dependencies have been installed, you can lunch the PYBOSSA development server:
vagrant ssh python run.py
Virtualenv (located in /home/vagrant/pybossa-env) is always activated on login.
Now all you have to do is open the following URL in your web browser: http://127.0.0.1:5000
And you are done! Happy Hacking !
PYBOSSA needs a RQ worker process. It is running by default permanently in the background in the VM and is controlled by supervisor. Optional is also the RQ scheduler process for speeding up tasks like ZIP creation. This process is off by default now. If you are developing on RQ worker, you want to restart or disable it with supervisorctl.
