Ansible variables
|
||
|
===============
|
||
|
|
||
|
|
||
|
Inventory
|
||
|
-------------
|
||
|
The inventory is composed of 3 groups:
|
||
|
|
||
|
* **kube-node** : list of kubernetes nodes where the pods will run.
|
||
|
* **kube-master** : list of servers where kubernetes master components (apiserver, scheduler, controller) will run.
|
||
|
Note: if you want the server to act both as master and node the server must be defined on both groups _kube-master_ and _kube-node_
|
||
|
* **etcd**: list of server to compose the etcd server. you should have at least 3 servers for failover purposes.
|
||
|
|
||
|
Below is a complete inventory example:
|
||
|
|
||
|
```
