Greg Althaus 6c69da1573 This PR adds/or modifies a few tasks to allow for the playbook to 
be run by limit on each node without regard for order.

The changes make sure that all of the directories needed to do
certificate management are on the master[0] or etcd[0] node regardless
of when the playbook gets run on each node.  This allows for separate
ansible playbook runs in parallel that don't have to be synchronized.

##Deploy a production ready kubernetes cluster

If you have questions, join us on the kubernetes slack, channel #kargo.

  • Can be deployed on AWS, GCE, Azure, 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
Ansible usual commands and inventory builder
vagrant by simply running vagrant up (for tests purposes)

Supported Linux distributions

  • Container Linux by CoreOS
  • Debian Jessie
  • Ubuntu 16.04
  • CentOS/RHEL 7

Note: Upstart/SysV init based OS types are not supported.

Versions of supported components

kubernetes v1.5.1
etcd v3.0.6
flanneld v0.6.2
calicoctl v0.23.0
canal (given calico/flannel versions)
weave v1.6.1
docker v1.12.5
rkt v1.21.0

Note: rkt support as docker alternative is limited to control plane (etcd and kubelet). Docker is still used for Kubernetes cluster workloads and network plugins' related OS services. Also note, only one of the supported network plugins can be deployed for a given single cluster.

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.
  • The target servers are configured to allow IPv4 forwarding.
  • Copy your ssh keys to all the servers part of your inventory.
  • Ansible v2.2 (or newer) and python-netaddr

Network plugins

You can choose between 4 network plugins. (default: flannel with vxlan backend)

  • flannel: gre/vxlan (layer 2) networking.

  • calico: bgp (layer 3) networking.

  • canal: a composition of calico and flannel plugins.

  • 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. There is also an option to leverage built-in cloud provider networking instead. See also Network checker.
