Systems Administration
|
|
======================
|
|
|
|
Fabric
|
|
------
|
|
|
|
Fabric is a library for simplifying system administration tasks. While Chef
|
|
and Puppet tend to focus on managing servers and system libraries,
|
|
fabric is more focused on application level tasks such as deployment.
|
|
|
|
Install Fabric:
|
|
|
|
::
|
|
|
|
pip install fabric
|
|
|
|
The following code will ssh into both of our servers, cd to our project
|
|
directory, activate the virtual environment, pull the newest codebase,
|
|
and restart the application server.
|
|
|
|
::
|
|
|
|
from fabric.api import cd, env, prefix, run, task
|
|
|
|
env.hosts = ['my_server1', 'my_server2']
|
|
|
|
@task
|
|
def deploy():
|
|
with cd('/var/www/project-env/project'):
|
|
with prefix('. ../bin/activate'):
|
|
run('git pull')
|
|
run('touch app.wsgi')
|
|
|
|
With the previous code saved in a file named fabfile.py, we merely need to run
|
|
the following command to deploy our application to both of our servers.
|
|
|
|
::
|
|
|
|
$ fab deploy
|
|
|
|
Additional features include parallel execution, interaction with remote
|
|
programs, and host grouping.
