dev

The cfy dev command is used to run fabric tasks on a Cloudify manager via SSH.

This supplies an easy way to run personalized, complex ssh scripts on the manager without having to manually connect to it.

For example, you could write a task that deploys and upgrades a monitoring agent you use to monitor your systems. During that manager’s lifecycle, you could rerun the same task to update that agent.

Usage

cfy dev [options] -p TASKS_FILE -t TASK

Run fabric tasks on the manager.

Required flags

• -t, --task=TASK - The name of fabric task to run
• -p, --tasks-file=TASKS_FILE - The path to the tasks file

Optional flags

• -a ..., --args ... - Arguments for the fabric task

Examples

$ cfy dev --tasks-file my_tasks.py -v -t my_task -a --arg1=something --arg2=otherthing ...
$ cfy dev -v -t my_task -a arg1_value arg2_value ...
...

--tasks-file my_tasks.py can be omitted if a tasks.py file exists in your current working directory.

For example, to echo something in your currently running Manager, you need only supply a tasks.py file with the following:

from fabric.api import run

def echo(text):
  run('echo {0}'.format(text))

$ cfy dev -t echo -a something

Cloudify provides a tasks repository from which users can obtain tasks and to which developers should contribute for the benefit of all.
