The deployer is a Python framework for automatic application deployment on
Posix systems, usually through SSH. When set up, it can be called as a
library, but usually, people use it through an interactive command line.
Some key features are:
- Interactive execution of remote commands, locally, they will appear in a
pseudo terminal (created with openpty), so that even editors like Vim or
Emacs works fine when you run them on the remote end.
- Reusability of all deployment code is a key point. It’s as declarative as
possible, but without loosing Python’s power to express everything as
dynamic as you’d like to. Deployment code is hierarchically structured, with
inheritance where possible.
- Parallel execution is easy when enabled, while keeping interaction with
these remote processes possible through pseudoterminals. Every process gets
his own terminal, either a new xterm or gnome-terminal window, a tmux pane, or
whatever you’d like to.
- Logging of your deployments. New loggers are easily pluggable into the
