CephAIO

Requires: Ansible 2.3.0 or higher

Creates an AIO for ceph using LXC containers

The goal of this project was to create an all in one enviroment of ceph that resembled what a production ceph cluster may look like. Each container is treated as a "server".

-------------------------------------------------------------------
| Container |    IP     |                  Type                   |
-------------------------------------------------------------------
| cephadmin | 10.0.3.51 | Deployment Host, ceph monitoring host   |
| cephmon   | 10.0.3.52 | ceph monitoring host                    |
| cephosd1  | 10.0.3.53 | ceph osd host                           |
| cephosd2  | 10.0.3.54 | ceph osd host                           |
| cephosd3  | 10.0.3.55 | ceph osd host                           |

Known to Work on:

  Rackspace Public Cloud
    - 15 GB Compute v1   
    - Ubuntu 16.04 LTS (Xenial Xerus) (PVHVM)  
    - 75 GB Standard SATA block device attached as /dev/xvdb

To build

cd CephAIO
bash bootstrap.sh
ansible-playbook -i inventory build.yml

To Teardown

ansible-playbook -i inventory teardown.yml

After using the teardown playbook, ensure that the ceph disk has been completely wiped. Ceph leaves some residual data that interferes with future deployments. The teardown playbook currently uses shred to perform the data wipe (this takes awhile), but I am pretty sure that removing the block device and adding a new one would accomplish the same end result.

TO DO:

• Add variable to control the number of osds deployed
• Add variable to remove the hardcoded /dev/xvdb
