Quickstart
|
||||
-------------------------
|
||||
The following steps will quickly setup a kubernetes cluster with default configuration.
|
||||
These defaults are good for tests purposes.

### Download binaries
|

A role allows to download required binaries. They will be stored in a directory defined by the variable
|
||||
**'local_release_dir'** (by default /tmp).
|

Please ensure that you have enough disk space there (about **1G**).

-------------------------
|
||||
### Multi master notes
|
||||
* You can choose where to install the master components. If you want your master node to act both as master (api,scheduler,controller) and node (e.g. accept workloads, create pods ...),
|
||||
the server address has to be present on both groups 'kube-master' and 'kube-node'.
|
||||
|
||||
* Almost all kubernetes components are running into pods except *kubelet*. These pods are managed by kubelet which ensure they're always running
|
||||
|
||||
* One etcd cluster member per node will be configured. For safety reasons, you should have at least two master nodes.
|
||||
|
||||
* Kube-proxy doesn't support multiple apiservers on startup ([#18174]('https://github.com/kubernetes/kubernetes/issues/18174')). An external loadbalancer needs to be configured.
|
||||
In order to do so, some variables have to be used '**loadbalancer_apiserver**' and '**apiserver_loadbalancer_domain_name**'
|
||||
|
||||
|
||||
### Network Overlay
|
||||
You can choose between 2 network plugins. Only one must be chosen.
