This script makes sure an ansible container is perpetually running and lets you exec scripts on it.

ansible

CONTAINER_NAME=ansible

function dpsgrep() {
	pattern=${1} && shift
	docker ps --format="{{ .Names }}" ${*} \
		| grep -q ${pattern}
	return ${?}
}

if ! $(dpsgrep "${CONTAINER_NAME}"); then
	echo "Container isn't running, checking if created."

	if ! $(dpsgrep "${CONTAINER_NAME}" --all); then
		echo "Container not created. Starting creation."
