When download_run_once with download_localhost is used, docker is expected to be running on the delegate localhost. That may be not the case for a non localhost delegate, which is the kube-master otherwise. Then the dnsmasq role, had it been invoked early before deployment starts, would fail because of the missing docker dependency. * Fix that dependency on docker and do not pre download dnsmasq image for the dnsmasq role, if download_localhost is disabled. * Remove become: false for docker CLI invocation because that's not the common pattern to allow users access docker CLI w/o sudo. * Fix opt bin path hack for localhost delegate to ignore errors when it fails with "sudo password required" otherwise. * Describe download_run_once with download_localhost use case in docs as well.

##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)
- Requirements
- Getting started
- Vagrant install
- CoreOS bootstrap
- Ansible variables
- Cloud providers
- OpenStack
- AWS
- Network plugins
- Roadmap
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

-
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 toweavetroubleshooting documentation)
The choice is defined with the variable kube_network_plugin
