Deploy with fabric on multiple servers

Ever needed to deploy with fabric on multiple machines?
Here’s a simple solution to aproach this issue.

In your fabfile.py , add these two methods:


def live():
    global PATH, ENV_PATH
    env.hosts = ["22.2.222.2"]
    env.user = 'test'
    PATH = '/path/to/project'
    # optional, is using virtualenv
    ENV_PATH = '/path/to/virtualenv'
    # overwrite whatever variabled you need to change on the current machine

def staging():
    global PATH, ENV_PATH
    env.hosts = ["11.1.11.1"]
    env.user = 'test2'
    PATH = '/path/to/project/on/second/machine'
    # optional, is using virtualenv
    ENV_PATH = '/path/to/virtualenv'
    # overwrite whatever variabled you need to change on the current machine

def live():

global PATH, ENV_PATH

env.hosts = ["22.2.222.2"]

env.user = 'test'

PATH = '/path/to/project'

# optional, is using virtualenv

ENV_PATH = '/path/to/virtualenv'

# overwrite whatever variabled you need to change on the current machine

def staging():

global PATH, ENV_PATH

env.hosts = ["11.1.11.1"]

env.user = 'test2'

PATH = '/path/to/project/on/second/machine'

# optional, is using virtualenv

ENV_PATH = '/path/to/virtualenv'

# overwrite whatever variabled you need to change on the current machine

Now, when deploying, for example:


def deploy():
    with cd(PATH), virtualenv(ENV_PATH):
        run('uber command')
        run('another uber command')

def deploy():

with cd(PATH), virtualenv(ENV_PATH):

run('uber command')

run('another uber command')

you must use the following commands, in the correct order:


#deploy on staging
fab staging deploy

# deploy on live
fab live deploy

#deploy on staging

fab staging deploy

# deploy on live

fab live deploy

Fabric runs the “staging” or “deploy” commands first, setting the envrinoment variables, and then it runs the “deploy” command doing whatever you asked it to do.
