Tooler: Create friendly devops tools in minutes

Project description

Tooler: Easier, better, faster python devops scripts
====================================================

Features:

* Simple access to local or remote (via asyncssh) shells
* Neat legible output from multiple hosts


Simple access to bash:
----------------------

.. code:: python
import shlex
from tooler import Tooler

tooler = Tooler()

@tooler.command
def free(mount='/'):
for result in tooler.bash('df -mah | grep %s' % shell_quote(mount + '$')):
fs, blocks, use, available, use_pct, mnt = shlex.split(result.stdout)
result.host.print('Used %s (%s) of %s [%s]' % (use, use_pct, mnt, fs))

if __name__ == '__main__':
tooler.main()


..
$ ./disk.py free --mount=/
local$ df -mah | grep '/$'
local> /dev/mapper/ubuntu--vg-root 102G 69G 28G 72% /
local: [✔]
local: Used 69G (72%) of / [/dev/mapper/ubuntu--vg-root]

Subcommands made easy:
----------------------

.. code:: python
from tooler import Tooler
from tooler.library import (named, SshConfig)

import disk

tooler = Tooler()

tooler.add_submodule('disk', disk.tooler)
tooler.add_submodule('named', named.tooler)

if __name__ == '__main__':
named.add_hosts(SshConfig().get_hosts())
tooler.main(hosts=[])

Library of awesome sauce:
-------------------------

..
$ ./tool.py named:nginx* disk.free
$ s named:nginx* free
nginx1$ df -mah | grep '/$'
nginx2$ df -mah | grep '/$'
nginx3$ df -mah | grep '/$'
nginx3> /dev/sda1 59G 37G 22G 64% /
nginx3: [✔]
nginx1> /dev/sda1 59G 37G 22G 64% /
nginx1: [✔]
nginx2> /dev/sda1 59G 37G 22G 64% /
nginx2: [✔]
nginx1: Used 37G (64%) of / [/dev/sda1]
nginx2: Used 37G (64%) of / [/dev/sda1]
nginx3: Used 37G (64%) of / [/dev/sda1]

Thanks required:
