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.
