Requirements
--------------
------------
* **Ansible v2.4 (or newer) and python-netaddr is installed on the machine
that will run Ansible commands**
* **Jinja 2.9 (or newer) is required to run the Ansible Playbooks**
* The target servers must have **access to the Internet** in order to pull docker images.
* The target servers are configured to allow **IPv4 forwarding**.
* **Your ssh key must be copied** to all the servers part of your inventory.
* The **firewalls are not managed**, you'll need to implement your own rules the way you used to.
in order to avoid any issue during deployment you should disable your firewall.

## Network plugins
Network Plugins
---------------
You can choose between 4 network plugins. (default: `calico`, except Vagrant uses `flannel`)
* [**flannel**](docs/flannel.md): gre/vxlan (layer 2) networking.
- [flannel](docs/flannel.md): gre/vxlan (layer 2) networking.
* [**calico**](docs/calico.md): bgp (layer 3) networking.
- [calico](docs/calico.md): bgp (layer 3) networking.
* [**canal**](https://github.com/projectcalico/canal): a composition of calico and flannel plugins.
- [canal](https://github.com/projectcalico/canal): a composition of calico and flannel plugins.
* [**contiv**](docs/contiv.md): supports vlan, vxlan, bgp and Cisco SDN networking. This plugin is able to
apply firewall policies, segregate containers in multiple network and bridging pods onto physical networks.
- [contiv](docs/contiv.md): supports vlan, vxlan, bgp and Cisco SDN networking. This plugin is able to
apply firewall policies, segregate containers in multiple network and bridging pods onto physical networks.
* [**weave**](docs/weave.md): Weave is a lightweight container overlay network that doesn't require an external K/V database cluster. <br>
(Please refer to `weave` [troubleshooting documentation](http://docs.weave.works/weave/latest_release/troubleshooting.html)).
- [weave](docs/weave.md): Weave is a lightweight container overlay network that doesn't require an external K/V database cluster.
(Please refer to `weave` [troubleshooting documentation](http://docs.weave.works/weave/latest_release/troubleshooting.html)).
The choice is defined with the variable `kube_network_plugin`. There is also an
option to leverage built-in cloud provider networking instead.

In the same directory of this ReadMe file you should find a file named `inventory.example` which contains an example setup. Please note that, additionally to the Kubernetes nodes/masters, we define a set of machines for GlusterFS and we add them to the group `[gfs-cluster]`, which in turn is added to the larger `[network-storage]` group as a child group.
Change that file to reflect your local setup (adding more machines or removing them and setting the adequate ip numbers), and save it to `inventory/k8s_gfs_inventory`.

This will provision your Kubernetes cluster. Then, to provision and configure the GlusterFS cluster, from the same directory execute:

```
If your machines are not using Ubuntu, you need to change the `--user=ubuntu` to the correct user. Alternatively, if your Kubernetes machines are using one OS and your GlusterFS a different one, you can instead specify the `ansible_ssh_user=<correct-user>` variable in the inventory file that you just created, for each machine/VM:
