## Upgrading Kubernetes
|
|
|
|
Upgrading Kubernetes is easy with kops. The cluster spec contains a `KubernetesVersion`, so you can simply edit it with `kops edit`, and apply the updated configuration to your cluster.
|
|
|
|
The `kops upgrade` command also automates checking for and applying updates.
|
|
|
|
Note: if you want to upgrade from a `kube-up` installation, please see the instructions for [how to upgrade kubernetes installed with kube-up](cluster_upgrades_and_migrations.md).
|
|
|
|
### Manual update
|
|
|
|
* `kops edit cluster $NAME`
|
|
* set the KubernetesVersion to the target version (e.g. `v1.3.5`)
|
|
* `kops update cluster $NAME` to preview, then `kops update cluster $NAME --yes`
|
|
* `kops rolling-update cluster $NAME` to preview, then `kops rolling-update cluster $NAME --yes`
|
|
|
|
### Automated update
|
|
|
|
* `kops upgrade cluster $NAME` to preview, then `kops upgrade cluster $NAME --yes`
|
|
|
|
In future the upgrade step will likely perform the update immediately (and possibly even without a
|
|
node restart), but currently you must:
|
|
|
|
* `kops update cluster $NAME` to preview, then `kops update cluster $NAME --yes`
|
|
* `kops rolling-update cluster $NAME` to preview, then `kops rolling-update cluster $NAME --yes`
|
|
|
|
Upgrade uses the latest Kubernetes version considered stable by kops, defined in `https://github.com/kubernetes/kops/blob/master/channels/stable`.
