Bogdan Dobrelya a03540dabc Add download localhost and enable for CI 
* Add download_localhost for the download_run_once mode, which is
  use the ansible host (a travis node for CI case) to store and
  distribute containers across cluster nodes in inventory.
  Defaults to false.
* Rework download_run_once logic to fix idempotency of uploading
  containers.
* For Travis CI, enable docker images caching and run Travis
  workers with sudo enabled as a dependency
* For Travis CI, deploy with download_localhost and download_run_once
  enabled to shourten dev path drastically.
* Add compression for saved container images. Defaults to 'best'.

##Deploy a production ready kubernetes cluster

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

  • 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 v1.4.6
etcd v3.0.6
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
