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.

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.

Prerequisites

  • An Operator previously installed using Operator Lifecycle Manager (OLM).

Procedure

  1. In the Administrator perspective of the OpenShift Container Platform web console, navigate to Operators → Installed Operators.

  2. Click the name of the Operator you want to change the update channel for.

  3. Click the Subscription tab.

  4. Click the name of the update channel under Channel.

  5. Click the newer update channel that you want to change to, then click Save.

  6. For Subscriptions with an Automatic approval strategy, the upgrade begins automatically. Navigate back to the Operators → Installed Operators page to monitor the progress of the upgrade. When complete, the status changes to Succeeded and Up to date.

    For Subscriptions with a Manual approval strategy, you can manually approve the upgrade from the Subscription tab.

Manually approving a pending Operator upgrade

If an installed Operator has the approval strategy in its subscription set to Manual, when new updates are released in its current update channel, the update must be manually approved before installation can begin.

Prerequisites

  • An Operator previously installed using Operator Lifecycle Manager (OLM).

Procedure

  1. In the Administrator perspective of the OpenShift Container Platform web console, navigate to Operators → Installed Operators.

  2. Operators that have a pending upgrade display a status with Upgrade available. Click the name of the Operator you want to upgrade.

  3. Click the Subscription tab. Any upgrades requiring approval are displayed next to Upgrade Status. For example, it might display 1 requires approval.

  4. Click 1 requires approval, then click Preview Install Plan.

  5. Review the resources that are listed as available for upgrade. When satisfied, click Approve.

  6. Navigate back to the Operators → Installed Operators page to monitor the progress of the upgrade. When complete, the status changes to Succeeded and Up to date.
