Subscription Management

Subscription describes the upgrade strategy, channel, and deployment information such as location for the Operator. Correct subscription information ensures that the Operator can successfully pull the required images and operate correctly.

Edit Subscription

In most cases, you do not need and should not edit subscription information. However, if you have sufficient Operator maintenance experience and wish to modify the deployment settings for the Operator, such as targeted deployment, taint tolerances, resource quotas, etc., the platform also provides a quick edit subscription feature.

Steps

1. In the left navigation pane, click Catalog > Operators.

2. On the Deployed Operators tab, click > Edit Subscription.

3. Modify the subscription information.

   Configuration Example

   config:
    nodeSelector:
       beta.kubernetes.io/arch: amd64
    tolerations:
       - key: "node.alpha.kubernetes.io/unreachable"
         operator: "Exists"
         effect: "NoExecute"
         tolerationSeconds: 6000

4. Click Confirm.

Update Upgrade Strategy

Note: If developers have specified an upgrade strategy when defining the Operator, you cannot update the upgrade strategy using the following method. To update the upgrade strategy, you can modify the corresponding YAML configuration file.

Steps

1. In the left navigation pane, click Catalog > Operators.

2. On the Deployed Operators tab, click the name of the Operator.

3. On the Subscription tab, click the icon next to Upgrade Strategy.

4. Update the upgrade strategy.

5. Click Update.

Delete Subscription

After uninstalling the Operator, although you can no longer use the Operator-related functionality through the platform, subscriptions may remain due to unknown reasons, and the Operator status may be abnormal. To prevent this from affecting the normal use of OperatorHub, you need to manually delete the subscriptions.

Steps

1. In the left navigation pane, click Catalog > Operators.

2. On the Deployed Operators tab, click the name of the Operator.

3. Click > Delete Subscription, and confirm.

   If you wish to use the Operator again, you can redeploy the Operator Deploy Operator .
