Add one more step (task) to containers download/upload sequence - copy saved .tar containers to ansible host (delegate_to: localhost). Then upload images to target nodes. It uses synchronize module so if ansible host (localhost) is the same host as kube-master[0] then new task causes no issues and the copy to localhost process is basically skipped. |

- 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
