supervisord for python 3?
The upcoming 4.0 release of Supervisord will support Python 2.7, and 3.4 and up. Until then, you could use the supervisor-py3k fork.
Or simply run supervisord with Python 2; your Python 3 codebase is otherwise unaffected, as supervisord is an independent process.
To use supervisord with Python 3 you can setup it directly with pip:
pip install git+https://github.com/Supervisor/supervisor
Python 3 support for supervisord is still experimental and as mentioned in documentation, you shouldn't use it in production.
Mozilla Foundation has developed a package called circus which works on Python 3.
It manages process with circusd and it also has circusctl, circus-top, circus-web(similar to supervisor).
You can use your supervisor conf file with circus with some changes. It also has a seperate section in docs for users coming from supervisor. You can read that for more details.
Update:Latest master has python 3 support. You can install it with
pip install git+https://github.com/Supervisor/supervisor
