quickrun

quickrun is a module designed to make it easy to run commands and gather info from multiple servers.

Dependencies

• python3.8
• aws cli (v1)

Getting started

Setup

Install:

pip3 install quickrun

Use:

import quickrun
from quickrun.cli.aws import find_instances

# Define instance
qr = quickrun.QuickRun()

# Configure

qr.servers = [ quickrun.Server(host="my-ip-address-or-hostname", name="my-web-server", user="username") ]
# or from aws cli
qr.servers = quickrun.Servers.from_list(find_instances({ 'tag:environment': 'production', 'tag:name': '*web*' }, region='eu-west-1'))

qr.commands = [ quickrun.Command(name="Get openssl version", cmd="openssl version") ]
qr.formatter = quickrun.formatters.table

# Call
qr.main()
qr.display()

This will display something like:

Making a script

Option 1: Basic script using some of the functions

You can just write a normal python script and use some of the functions from this module.
See examples/healthcheck.py as an example.

Option 2: Calling out to QuickRun

There is also the base QuickRun class which can be configured and called.
See examples/openssl-version.py and examples/list-logs.py as examples.

Option 3: Extending QuickRun

You could also create your own class extending from QuickRun.
This is handy since you can override the hook methods.
See examples/get-memory-settings.py as an example.

Helpers

There are a few core helpers built in to quickrun.

Formatters

There are a few formatters defined in quickrun.formatters

• default: Just prints out the python object
• none: Does nothing
• fake_shell: Formats the run as if it was ran directly
• table: Outputs the run as a table

cli.aws

There is also a helpful quickrun.cli.aws.find_instances() function that takes a dict of filters and returns matching instances.

Example:

find_instances({ 'tag:name': 'web', 'tag:environment': 'prod' }, region='eu-west-1')

cli.helpers

There is a collection of misc CLI helpers in quickrun.cli.helpers.
Currently there is only challenge(expect: str) -> bool which prompts the user to re-enter a value.
