# CephAIO
Requires: Ubuntu 16.04 and 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 |
| cephrgw | 10.0.3.56 | ceph rados gateway 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:
* unmounted
* unformatted
* listed in AIO_user_config (defauolt: /dev/xvdb)
```
### Boot Strap the Host
Use **bootstrap.sh** to stage the host:
Add ansible repo and run update package lists
```
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
```
Install ansible
```
sudo apt-get install -y ansible
```
Create a passwordless ssh-key and copy the key to itself
```
su - $USER -c "echo |ssh-keygen -t rsa"
cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
```
Disable password entry
```
sed -i '/PasswordAuthentication yes/c\PasswordAuthentication no' /etc/ssh/sshd_config
```
### To Create the CephAIO
```
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.
### Clean Up
` ansible-playbook -i inventory cleanup.yml `
If the containers and drives are created but the installation of ceph fails then ` cleanup.yml ` will stop and destory the containers then remove the 3 partitions from the external drive and then run the ' shred ` command. This provides the ability to reset the host back to a clean state if an error installing ceph happens.
### Tests
The directory **tests** contains information on how to test the success of some installed components.
TO DO:
- Add variable to control the number of osds deployed
