3.2. Upgrading installed Operators
As a cluster administrator, you can upgrade Operators that have been previously installed using Operator Lifecycle Manager (OLM) on your OpenShift Container Platform cluster.
3.2.1. Changing the update channel for an Operator
The Subscription of an installed Operator specifies an update channel, which is used to track and receive updates for the Operator. To upgrade the Operator to start tracking and receiving updates from a newer channel, you can change the update channel in the Subscription.
The names of update channels in a Subscription can differ between Operators, but should follow a common convention within a given Operator. Some naming schemes include:
-
4.3,4.4,4.5 -
stable-4.3,stable-4.4,stable-4.5 -
alpha,beta,stable,latest
Alternatively, the channel names might follow the version numbers of the application provided by the Operator.
Installed Operators cannot change to a channel that is older than the current channel.
If the approval strategy in the subscription is set to Automatic, the upgrade process initiates as soon as a new Operator version is available in the selected channel. If the approval strategy is set to Manual, you must manually approve pending upgrades.
