Upgrading Tectonic & Kubernetes

Use Tectonic Console to control the process by which Tectonic and Kubernetes are updated. Clusters are attached to an update channel and are set to update either automatically, or with admin approval.

Cluster update settings in the Console

During an update, the latest versions of the Tectonic and Kubernetes components are downloaded. A seamless rolling update will occur to install the latest versions. A cluster admin can pause the update at any time.

Please note that the update payload process may affect any or all components in the tectonic-system and kube-system namespaces.

To learn more about how this process is executed, read about Operators.

Preserve & Restore etcd

If you'd like to preserve and restore etcd data to the new cluster, see the etcd disaster recovery guide.
