Bash function to run commands against ansible hosts

I haven’t posted anything ansible related in a while, so here is a nifty little function I regularly use when I want to execute something on all (or a subset) of ansible hosts. It’s just a wrapper around ansible host -m script -a scriptname.sh but adds –tree so that the output is stored and can easily be parsed by jq

ansible_run() {
	local ansible_directory="${HOME}/svn/ansible/"
	local command=${1}
	local target=${2:-all}
	local dir="${HOME}/ansible_output/${RANDOM:0:5}"
	local startdir=
	local script=

	startdir="$(pwd)"
	script="$(mktemp)"
	mkdir -p "${dir}"
	if [[ $? -eq 0 ]] ; then
		{
			echo "#!/usr/bin/env bash"
			echo "${command}"
			echo
		} > "${script}"
		cd "${ansible_directory}" && time ansible "${target}" -m script -a "${script}" --tree "${dir}"
		rm "${script}"
		echo -e "\n${dir}\n"
	fi
	rmdir --ignore-fail-on-non-empty "${dir}"
	cd "${startdir}" || exit
}

ansible_run() {

local ansible_directory="${HOME}/svn/ansible/"

local command=${1}

local target=${2:-all}

local dir="${HOME}/ansible_output/${RANDOM:0:5}"

local startdir=

local script=

startdir="$(pwd)"

script="$(mktemp)"

mkdir -p "${dir}"

if [[ $? -eq 0 ]] ; then

{

echo "#!/usr/bin/env bash"

echo "${command}"

echo

} > "${script}"

cd "${ansible_directory}" && time ansible "${target}" -m script -a "${script}" --tree "${dir}"

rm "${script}"

echo -e "\n${dir}\n"

rmdir --ignore-fail-on-non-empty "${dir}"

cd "${startdir}" || exit

}

Usage example:

$ ansible_run "iptables -S | grep -E '^-P (INPUT|FORWARD)'"
...
/home/user/ansible_output/6599

$ cd ${HOME}/ansible_output/6599
$ jq -r .stdout ./*

$ ansible_run "iptables -S | grep -E '^-P (INPUT|FORWARD)'"

...

/home/user/ansible_output/6599

$ cd ${HOME}/ansible_output/6599

$ jq -r .stdout ./*
