# DEMO for OVH Summit 2017
This is a demo to showcase how to easily create spot instances to load-balance traffic from a busy wordpress site.
There are 4 files in this repo. The 2 .yaml files are what is passed to cloud-init when creating the instances. The 2 .sh are used to spawn the instance properly
## REQUIREMENTS
For the following scrips to work, we already assume you have:
- An OVH IP Load-Balancer service.
- Already have a 'farm' configured on the IPLB
- Some OVH API creadentials for the OVH api so we can configure the IPLB.
- Application key
- Application secret
- Consumer key
- A vRack with your PCI project already added to it.
- A network already created inside the vRack
You will also need to edit the variables in both .sh scripts to mirror your own config choices.
## USAGE
You will first need to edit both create_mysql.sh and add_server.sh and make sure the variables reflect your infra
If you do not already have a mysql server running your wordpress website, you first need to create a mysql instance. Simply run the following command
```bash
./create_mysql.sh
```
Next just create 1 instance of the web frontend to verify that all is working
```bash
./add_server.sh
```
You can now visit your IPLB ip and verify that all is working. SUCCESS
If you want to add more than one web frontends at once you can do
```bash
for i in {1..5}; do ./add_server.sh web-0$1 ; done
```
## Description
#### mysql.yaml
- installs mysql
- configures vRack interface
- configures mysql to listen only on vRack IP
- firewall all but ICMP and SSH on public IP
#### web-frontend.yaml
- configures wordpress
- configures apache
- configures vRack interface
- configures iplb
#### create_mysql.sh
- creates an instance running a mysql server
#### add_server.sh
- creates a new wordpress
- instance points to existing mysql instance
- instance auto-adds itself to iplb
- on instance deletion auto-removes itself from iplb
## WHAT NEXT
This demo is not fully fonctional and there are a few things we can add to make it fully fonctional.
#### Make wordpress media read/write from object storage
This demo does not take into acount media added into wordpress, only one of the web frontends will receive it. To fix this you could write/use a wordpress plugin to offload media to Object Storage like the OVH PCS service which is OpenStack Swift.
#### Configure everything will only scripts
As seen in the "REQUIREMENTS" section, there are a few things that are assumed before using this demo. All of these can be done programaticaly.
- Order and prepare IPLB
- Create OVH API credentials
- Add your PCI project to the vRack
- Create the vRack network
We can even think of adding new thing like using a domain, configuring it's DNS and making sure apache takes it into account
#### Add more automation
Both bash scripts in this repo are the "glue" to create the instances, but all this can be achieved with [terraform](https://www.terraform.io).
You could also make a basic cloud-init files to simply install and configure orchestration tools like puppet/chef/ansible/salt and then deploy the actual application with them.
