# wrapper around aws s3 to simpllify get/put of secure resources from our s3 bucket.

AWS:= aws
S3:=s3://secure.example.com
S3PATH:=/
FILE=secure.conf

REMOTE=${S3}${S3PATH}${FILE}

help:
	@echo "get: fetch secure.conf from S3"
	@echo "put: put secure.conf to S3"
	@echo "ls: list secure.conf on remote S3"
	@echo "g_keys: get authorized_keys from S3"
	@echo "p_keys: push authorized_keys from S3"
	@echo "ls_keys: list authorized_keys on S3"
	@echo "vars: list vars"

vars:
	@echo "S3: ${S3}"
	@echo "S3PATH: ${S3PATH}"
	@echo "FILE: ${FILE}"


p_keys g_keys ls_keys: S3PATH=/users/airmedia/
p_keys g_keys ls_keys: FILE=authorized_keys

g_keys: get
p_keys: put

fetch: get
get:
	${AWS} s3 cp ${REMOTE} ${FILE}
put:
	${AWS} s3 cp ${FILE} ${REMOTE}
ls:
	${AWS} s3 ls ${REMOTE}
