gonzo 0.1.4

Configuration

Setup your clouds

Command Line Interface

Having setup multiple cloud environments and/or regions within, use the gonzo config command to chose where you want to deploy servers or projects to:

$ gonzo config
cloud: None
region: None
$ gonzo config --cloud aws
cloud: aws
region: eu-west-1
$ gonzo config --region us-west-1
cloud: aws
region: us-west-1

Managing the instance lifecycle

Having chosen the cloud and region you want to work within you can issue gonzo commands to control the spinning up, monitoring and termination of instances within.

To see a list of all running instance in the region:

$ gonzo list
production-sql-004          m1.small   ACTIVE   david    20d 20h 4m 23s
production-web-004          m1.small   ACTIVE   fergus   7d 23h 45m 3s

To add a new instance to the region, specifying the server type - having defined server types, and their sizes in your config:

$ gonzo launch production-web

To get more info on the commands available:

$ gonzo --help

Using gonzo with fabric

You can then use gonzo to set a target server (or group of servers) for fabric commands.

Import gonzo in your fabfile to extend fab with gonzo functionality:

$ cat fabfile.py

from gonzo.tasks import gonzo
__all__ = ['gonzo']

You can then run a command on a single instance, specifying it through gonzo:

$ fab gonzo.instance:production-web-003 run_command

Or run the command on a group of instances:

$ fab gonzo.group:production-web run_command

Fabric task library

To use the gonzo library of fabric tasks, simply import the relevant task modules for namespaced tasks into your fabfile:

from gonzo.tasks import apache

These can then be called using the standard fabric syntax:

$ fab gonzo.group:production-web apache.restart

Alternatively import the tasks directly:

from gonzo.tasks.apache import restart

These commands won’t be namespaced:

$ fab gonzo.group:production-web restart

You can extend the functionality by patching your own commands into the gonzo namespaces to provide a clean CLI:

# ~/apache_maintenance_mode.py
from fabric.api import task, sudo
from gonzo.tasks import apache

def maintenance_mode(off=False):
    """ Set server into maintenance mode.
    """

    if off:
        sudo("a2ensite onefinestay && a2dissite 00maintenance")
    else:
        sudo("a2ensite 00maintenance && a2dissite onefinestay")

apache.maintenance_mode = task(maintenance_mode)
