From 7216185f0d5f0740abbc95c31a3b90993911f74f Mon Sep 17 00:00:00 2001 From: Jeremy Asher Date: Fri, 4 Nov 2016 14:41:16 -0700 Subject: [PATCH 1/5] implement aws_snapshot_create_volume_permission This adds the new resource aws_snapshot_create_volume_permission which manages the createVolumePermission attribute of snapshots. This allows granting an AWS account permissions to create a volume from a particular snapshot. This is often required to allow another account to copy a private AMI. --- builtin/providers/aws/provider.go | 1 + ...e_aws_snapshot_create_volume_permission.go | 104 ++++++++++++++++++ 2 files
