Quick Start
|
||||
-----------
|
||||
|
||||
To deploy the cluster you can use :
|
||||
|
||||
**Ansible** usual commands and [**inventory builder**](https://github.com/kubernetes-incubator/kubespray/blob/master/contrib/inventory_builder/inventory.py) <br>
|
||||
**vagrant** by simply running `vagrant up` (for tests purposes) <br>
|
||||
### Ansible
|
||||
|
||||
# Copy ``inventory/sample`` as ``inventory/mycluster``
|
||||
cp -rfp inventory/sample inventory/mycluster

|
||||
|
||||
* [**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.

option to leverage built-in cloud provider networking instead.

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

```

ansible-playbook -b --become-user=root -i inventory/k8s_gfs_inventory --user=ubuntu ./contrib/network-storage/glusterfs/glusterfs.yml

|
||||
```
|
||||
|
||||
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:
