+This is an installation tool for opensds using ansible.
+
+## 1. How to install an opensds local cluster
+### Pre-config (Ubuntu 16.04)
+First download some system packages:
+```
+sudo apt-get install -y openssh-server git make gcc
+```
+Then config ```/etc/ssh/sshd_config``` file and change one line:
+```conf
+PermitRootLogin yes
+```
+Next generate ssh-token:
+```bash
+ssh-keygen -t rsa
+ssh-copy-id -i ~/.ssh/id_rsa.pub <ip_address> # IP address of the target machine of the installation
+```
+
+### Install docker
+If use a standalone cinder as backend, you also need to install docker to run cinder service. Please see the [docker installation document](https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/) for details.
+
+### Install ansible tool
+To install ansible, you can run `install_ansible.sh` directly or input these commands below:
+```bash
+sudo add-apt-repository ppa:ansible/ansible # This step is needed to upgrade ansible to version 2.4.2 which is required for the ceph backend.
+sudo apt-get update
+sudo apt-get install ansible
+ansible --version # Ansible version 2.4.2 or higher is required for ceph; 2.0.0.2 or higher is needed for other backends.
+```
+
+### Configure opensds cluster variables:
+##### System environment:
+Configure these variables below in `group_vars/common.yml`:
+```yaml
+opensds_release: v0.1.4 # The version should be at least v0.1.4.
+nbp_release: v0.1.0 # The version should be at least v0.1.0.
+
+container_enabled: <false_or_true>
+```
+
+If you want to integrate OpenSDS with cloud platform (for example k8s), please modify `nbp_plugin_type` variable in `group_vars/common.yml`:
+```yaml
+nbp_plugin_type: standalone # standalone is the default integration way, but you can change it to 'csi', 'flexvolume'
+```
+
+#### Database configuration
+Currently OpenSDS adopts `etcd` as database backend, and the default db endpoint is `localhost:2379,localhost:2380`. But to avoid some conflicts with existing environment (k8s local cluster), we suggest you change the port of etcd cluster in `group_vars/osdsdb.yml`:
+```yaml
+db_endpoint: localhost:62379,localhost:62380
+
+etcd_host: 127.0.0.1
+etcd_port: 62379
+etcd_peer_port: 62380
+```
+
+##### LVM
+If `lvm` is chosen as storage backend, modify `group_vars/osdsdock.yml`:
+```yaml
+enabled_backend: lvm # Change it according to the chosen backend. Supported backends include 'lvm', 'ceph', and 'cinder'
+pv_devices: # Specify block devices and ensure them existed if you choose lvm
+ #- /dev/sdc
+ #- /dev/sdd
+vg_name: "specified_vg_name" # Specify a name for VG if choosing lvm
+```
+Modify ```group_vars/lvm/lvm.yaml```, change pool name to be the same as `vg_name` above:
+```yaml
+"vg001" # change pool name to be the same as vg_name
+```
+##### Ceph
+If `ceph` is chosen as storage backend, modify `group_vars/osdsdock.yml`:
+```yaml
+enabled_backend: ceph # Change it according to the chosen backend. Supported backends include 'lvm', 'ceph', and 'cinder'.
+ceph_pools: # Specify pool name randomly if choosing ceph
+ - rbd
+ #- ssd
+ #- sas
+```
+Modify ```group_vars/ceph/ceph.yaml```, change pool name to be the same as `ceph_pool_name`. But if you enable multiple pools, please append the current pool format:
+```yaml
+"rbd" # change pool name to be the same as ceph pool
+```
+Configure two files under ```group_vars/ceph```: `all.yml` and `osds.yml`. Here is an example:
+
+```group_vars/ceph/all.yml```:
+```yml
+ceph_origin: repository
+ceph_repository: community
+ceph_stable_release: luminous # Choose luminous as default version
+public_network: "192.168.3.0/24" # Run 'ip -4 address' to check the ip address
+cluster_network: "{{ public_network }}"
+monitor_interface: eth1 # Change to the network interface on the target machine
+```
+```group_vars/ceph/osds.yml```:
+```yml
+devices: # For ceph devices, append ONE or MULTIPLE devices like the example below:
+ - '/dev/sda' # Ensure this device exists and available if ceph is chosen
+ - '/dev/sdb' # Ensure this device exists and available if ceph is chosen
+osd_scenario: collocated
+```
+
+##### Cinder
+If `cinder` is chosen as storage backend, modify `group_vars/osdsdock.yml`:
+```yaml
+enabled_backend: cinder # Change it according to the chosen backend. Supported backends include 'lvm', 'ceph', and 'cinder'
+
+# Use block-box install cinder_standalone if true, see details in:
+use_cinder_standalone: true
+# If true, you can configure cinder_container_platform, cinder_image_tag,
+# cinder_volume_group.
+
+# Default: debian:stretch, and ubuntu:xenial, centos:7 is also supported.
+cinder_container_platform: debian:stretch
+# The image tag can be arbitrarily modified, as long as follow the image naming
+# conventions, default: debian-cinder
+cinder_image_tag: debian-cinder
+# The cinder standalone use lvm driver as default driver, therefore `volume_group`
+# should be configured, the default is: cinder-volumes. The volume group will be
+# removed when use ansible script clean environment.
+cinder_volume_group: cinder-volumes
+```
+
+Configure the auth and pool options to access cinder in `group_vars/cinder/cinder.yaml`. Do not need to make additional configure changes if using cinder standalone.
+
+### Check if the hosts can be reached
+```bash
+sudo ansible all -m ping -i local.hosts
+```
+
+### Run opensds-ansible playbook to start deploy
+```bash
+sudo ansible-playbook site.yml -i local.hosts
+```
+
+## 2. How to test opensds cluster
+
+### Configure opensds CLI tool
+```bash
+sudo cp /opt/opensds-{opensds-release}-linux-amd64/bin/osdsctl /usr/local/bin
+export OPENSDS_ENDPOINT=http://127.0.0.1:50040
+export OPENSDS_AUTH_STRATEGY=noauth
+
+osdsctl pool list # Check if the pool resource is available
+```
+
+### Create a default profile first.
+```
+osdsctl profile create '{"name": "default", "description": "default policy"}'
+```
+
+### Create a volume.
+```
+osdsctl volume create 1 --name=test-001
+```
+For cinder, az needs to be specified.
+```
+osdsctl volume create 1 --name=test-001 --az nova
+```
+
+### List all volumes.
+```
+osdsctl volume list
+```
+
+### Delete the volume.
+```
+osdsctl volume delete <your_volume_id>
+```
+
+
+## 3. How to purge and clean opensds cluster
+
+### Run opensds-ansible playbook to clean the environment
+```bash
+sudo ansible-playbook clean.yml -i local.hosts
+```
+
+### Run ceph-ansible playbook to clean ceph cluster if ceph is deployed
+```bash
+cd /opt/ceph-ansible
+sudo ansible-playbook infrastructure-playbooks/purge-cluster.yml -i ceph.hosts
+```
+
+### Remove ceph-ansible source code (optional)
+```bash
+cd ..
+sudo rm -rf /opt/ceph-ansible
+```
