5.2.8 Updating the Kubernetes Release

Important

Before you update or upgrade the Kubernetes cluster, make sure you have updated or upgraded Oracle Linux Cloud Native Environment to the latest release. For information on updating or upgrading Oracle Linux Cloud Native Environment, see Updates and Upgrades.

Use the olcnectl module update command to update to the latest Kubernetes errata release, or to update to a new Kubernetes release. For example, to update the Kubernetes module named mycluster in the myenvironment environment to the latest Kubernetes errata release:

$ olcnectl --api-server 127.0.0.1:8091 module update --environment myenvironment \
  --name mycluster

The nodes in the environment are updated to the latest Kubernetes errata release.

Use the olcnectl module update command to upgrade to the latest Kubernetes release. For example, to upgrade to Kubernetes Release 1.17, enter:

$ olcnectl --api-server 127.0.0.1:8091 module update --environment-name myenvironment \
  --name mycluster \
  --kube-version 1.17.9

The --kube-version option specifies the release to which you want to upgrade. This example uses release number 1.17.9.

Important

Make sure you upgrade to the latest Kubernetes release. To get the version number of the latest Kubernetes release, see Release Notes.

The nodes in the environment are updated to Kubernetes Release 1.17.
