cbsmith / awscli_functions.sh

Created December 15, 2015 05:13

A handy collection of bash functions to make the aws cli a bit more usable

	# Usage: . awscli_functions.sh
	# Suggested: add to ~/.bashrc
	# This code lazily uses your default profile && region.
	# It wouldn't take much to add some logic for using ${PROFILE} and/or ${REGION} as some kind of override.
	# Lots more functions would be helpful, but I've been playing with ec2 & vpcs a lot lately, so...

	clusters()
	{
	local __resultvar=$1
	local __clusters=$(aws ecs list-clusters \| jq -r '.clusterArns[]')

modifying fleet metadata (from aws meta-data service) before fleet.service start; this is a proof of concept (but it works!)

	---
	coreos:
	units:
	- name: update-fleet-metadata.service
	command: start
	content: \|-
	[Unit]
	Description=Update Fleet metadata tag

	'''Convert a format string keyword formatted query to a ? wildcarded prepared statement
	that is pyodbc compatible, along with the args tuple to pass to it.
	* format_string: Python format compatible representation of a query
	* args: positional args for the format string
	* kwargs: keyword args for the format string
