From 812ff6ca9fcd3e629e49d4328905f33eee8ca3f5 Mon Sep 17 00:00:00 2001 From: Qiaowei Ren Date: Thu, 4 Jan 2018 13:43:33 +0800 Subject: initial code repo This patch creates initial code repo. For ceph, luminous stable release will be used for base code, and next changes and optimization for ceph will be added to it. For opensds, currently any changes can be upstreamed into original opensds repo (https://github.com/opensds/opensds), and so stor4nfv will directly clone opensds code to deploy stor4nfv environment. And the scripts for deployment based on ceph and opensds will be put into 'ci' directory.
