Fabric: Quick Start

 
"Fabric is a high level Python (2.7, 3.4+) library designed to execute shell commands remotely over SSH" (https://www.fabfile.org/)

install

$ pip install fabric3

define command

 By default, fabfile.py is used to run the script. Create fabfile.py like:

from fabric.api import env, local, run

env.hosts = ['192.168.11.8']
env.user = 'tomo'
env.password = '12345678'

def check():
  local('hostname')
  run('hostname')

 You can list the defined commands:

$ fab -l

Available commands:

    check

 

run command

$ fab check

[192.168.11.8] Executing task 'check'
[localhost] local: hostname
tomo.local
[192.168.11.8] run: hostname
[192.168.11.8] out: myhost
[192.168.11.8] out: 

Done.
Disconnecting from 192.168.11.8... done.

 

upload file

Modify fabfile.py to define another task  to use 'put' feature:

from fabric.api import env, local, run, put

env.hosts = ['192.168.11.8']
env.user = 'tomo'
env.password = '12345678'

def check():
  local('hostname')
  run('hostname')

def upload():
  put('hello.txt', '.')

$ echo 'hello' > hello.txt
$ fab upload

[192.168.11.8] Executing task 'upload'
[192.168.11.8] put: hello.txt -> ./hello.txt

Done.
Disconnecting from 192.168.11.8... done.

The file is uploaded to /home/tomo/hello.txt on 192.168.11.8
