Upgrade Rancher on NetApp HCI
To upgrade Rancher software, you can use the NetApp Hybrid Cloud Control (HCC) UI or
REST API. HCC provides an easy button process to upgrade the components of your
Rancher deployment, including Rancher server, Rancher Kubernetes Engine (RKE), and
the management cluster’s node OS (for security updates). You can alternatively use the
API to help automate upgrades.
Upgrades are available by component instead of a cumulative package. As such, some component upgrades
such as the Ubuntu OS come available on a more rapid cadence. Upgrades affect only your Rancher server
instance and the management cluster that Rancher Server is deployed on. Upgrades to the management
cluster node’s Ubuntu OS are for critical security patches only and do not upgrade the operating system. User
clusters cannot be upgraded from NetApp Hybrid Cloud Control.
What you’ll need
• Admin privileges: You have storage cluster administrator permissions to perform the upgrade.
• Management services: You have updated your management services bundle to the latest version.
You must upgrade to the latest management services bundle 2.17 or later for Rancher
functionality.
• System ports: If you are using NetApp Hybrid Cloud Control for upgrades, you have ensured that the
necessary ports are open. See Network ports for more information.
