##Deploy a production ready kubernetes cluster

If you have questions, you can invite yourself to chat with us on Slack!

Can be deployed on AWS, GCE, OpenStack or Baremetal
High available cluster
Composable (Choice of the network plugin for instance)
Support most popular Linux distributions
Continuous integration tests

To deploy the cluster you can use :

kargo-cli (deprecated, a newer go version soon)
Ansible usual commands
vagrant by simply running vagrant up (for tests purposes)

Supported Linux distributions

CoreOS
Debian Wheezy, Jessie
Ubuntu 14.10, 15.04, 15.10, 16.04
Fedora 23
CentOS/RHEL 7

Versions

kubernetes v1.4.3
etcd v3.0.1
flanneld v0.6.2
calicoctl v0.22.0
weave v1.6.1
docker v1.10.3

Requirements

The target servers must have access to the Internet in order to pull docker images.
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
Copy your ssh keys to all the servers part of your inventory.
Ansible v2.x and python-netaddr

Network plugins

You can choose between 3 network plugins. (default: flannel with vxlan backend)

flannel: gre/vxlan (layer 2) networking.
calico: bgp (layer 3) networking.
weave: Weave is a lightweight container overlay network that doesn't require an external K/V database cluster.
(Please refer to weave troubleshooting documentation)

The choice is defined with the variable kube_network_plugin
