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:
## Configure 'ip' variable to bind kubernetes services on a
## different ip than the default iface
node1 ansible_ssh_host=95.54.0.12 # ip=10.3.0.1
node2 ansible_ssh_host=95.54.0.13 # ip=10.3.0.2
node3 ansible_ssh_host=95.54.0.14 # ip=10.3.0.3
node4 ansible_ssh_host=95.54.0.15 # ip=10.3.0.4
node5 ansible_ssh_host=95.54.0.16 # ip=10.3.0.5
node6 ansible_ssh_host=95.54.0.17 # ip=10.3.0.6
