|
|
`kubeadm upgrade` is a user-friendly command that wraps complex upgrading logic behind one command, with support
|
|
for both planning an upgrade and actually performing it. `kubeadm upgrade` can also be used for downgrading
|
|
cluster if necessary.

## kubeadm upgrade guidance
|
|
|
|
Every upgrade process might be a bit different, so we've documented each minor upgrade process individually.
|
|
For more version-specific upgrade guidance, see the following resources:
|
|
|
|
* [1.10 to 1.11 upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-11/)
|
|
* [1.11 to 1.12 upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-12/)
|
|
* [1.12 to 1.13 upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-13/)
|
|
* [1.13 to 1.14 upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-14/)
|

|
|
_For older versions, please refer to older documentation sets on the Kubernetes website._
|
|
|
|
In Kubernetes v1.11.0 and later, you can use `kubeadm upgrade diff` to see the changes that would be
|
|
applied to static pod manifests.
|
|
|
|
To use kube-dns with upgrades in Kubernetes v1.13.0 and later please follow [this guide](/docs/reference/setup-tools/kubeadm/kubeadm-init-phase/#cmd-phase-addon).
