### Upgrading a Cluster
|
||||
|
||||
If you already have a kubernetes cluster, and want to upgrade to a new version,
|
||||
you can use following command in cluster/ directory to update the whole cluster or a specified node to a new version.
|
||||
|
||||
```console
|
||||
$ KUBERNETES_PROVIDER=ubuntu ./kube-push.sh [-m|-n <node id>] <version>
|
||||
```
|
||||
|
||||
It can be done for all components (by default), master(`-m`) or specified node(`-n`).
|
||||
If the version is not specified, the script will try to use local binaries.You should ensure all the binaries are well prepared in path `cluster/ubuntu/binaries`.
|
||||
|
||||
```console
|
||||
$ tree cluster/ubuntu/binaries
|
||||
binaries/
|
||||
├── kubectl
|
||||
├── master
|
||||
│ ├── etcd
|
||||
│ ├── etcdctl
|
||||
│ ├── flanneld
|
||||
│ ├── kube-apiserver
|
||||
│ ├── kube-controller-manager
|
||||
│ └── kube-scheduler
|
||||
└── minion
|
||||
├── flanneld
|
||||
├── kubelet
|
||||
└── kube-proxy
|
||||
```
|
||||
|
||||
Upgrading single node is experimental now. You can use following command to get a help.
|
||||
|
||||
```console
|
||||
$ KUBERNETES_PROVIDER=ubuntu ./kube-push.sh -h
|
||||
```
|
||||
|
||||
Some examples are as follows:
|
||||
|
||||
* upgrade master to version 1.0.5: `$ KUBERNETES_PROVIDER=ubuntu ./kube-push.sh -m 1.0.5`
|
||||
* upgrade node 10.10.103.223 to version 1.0.5 : `$ KUBERNETES_PROVIDER=ubuntu ./kube-push.sh -n 10.10.103.223 1.0.5`
|
||||
* upgrade master and all nodes to version 1.0.5: `$ KUBERNETES_PROVIDER=ubuntu ./kube-push.sh 1.0.5`
|
||||
|
||||
The script will not delete any resources of your cluster, it just replaces the binaries.
|
||||
You can use `kubectl` command to check if the newly upgraded k8s is working correctly.
|
||||
For example, use `$ kubectl get nodes` to see if all of your nodes are ready.Or refer to [test-it-out](ubuntu.md#test-it-out)
