title: kubeadm upgrade phase
weight: 90
---
In v1.15.0, kubeadm introduced preliminary support for `kubeadm upgrade node` phases.
Phases for other `kubeadm upgrade` sub-commands such as `apply`, could be added in the
following releases.

## kubeadm upgrade node phase {#cmd-node-phase}

Using this phase you can choose to execute the separate steps of the upgrade of
secondary control-plane or worker nodes. Please note that `kubeadm upgrade apply` still has to
be called on a primary control-plane node.

## What's next
* [kubeadm init](/docs/reference/setup-tools/kubeadm/kubeadm-init/) to bootstrap a Kubernetes control-plane node
* [kubeadm join](/docs/reference/setup-tools/kubeadm/kubeadm-join/) to connect a node to the cluster
* [kubeadm reset](/docs/reference/setup-tools/kubeadm/kubeadm-reset/) to revert any changes made to this host by `kubeadm init` or `kubeadm join`
* [kubeadm upgrade](/docs/reference/setup-tools/kubeadm/kubeadm-upgrade/) to upgrade a kubeadm node
* [kubeadm alpha](/docs/reference/setup-tools/kubeadm/kubeadm-alpha/) to try experimental functionality
