How to set target hosts in Fabric file

Question

I want to use Fabric to deploy my web app code to development, staging and production servers. My fabfile:

def deploy_2_dev():
  deploy(\'dev\')

def deploy_         


        

Answer 1

So, in order to set the hosts, and have the commands run across all the hosts, you have to start with:

def PROD():
    env.hosts = ['10.0.0.1', '10.0.0.2']

def deploy(version='0.0'):
    sudo('deploy %s' % version)

Once those are defined, then run the command on the command line:

fab PROD deploy:1.5

What will run the deploy task across all of the servers listed in the PROD function, as it sets the env.hosts before running the task.
