Customize the Update Configuration for Distributed Cloud Update Orchestration¶
You can adjust how the nodes in each subcloud are updated.
About this task
The update strategy for Distributed Cloud Update Orchestration uses separate configuration settings to control how the nodes on a given system are updated. You can adjust the settings used by default for all subclouds, and you can create custom settings for individual subclouds.
You can change the configuration settings before or after creating a update strategy for Distributed Cloud update orchestration. The settings are maintained independently.
Procedure
Select the SystemController region.
Select Distributed Cloud Admin > Orchestration.
On the Orchestration page, select the Cloud Patching Configuration tab.
Take one of the following actions:
To edit the settings applicable to all subclouds by default, click Edit Configuration in the all clouds default row.
To save your changes, click Edit Cloud Patching Configuration.
To create custom settings for an individual subcloud, click Create New Cloud Patching Configuration.
In the Subcloud field, select the subcloud for the custom settings.
To save your configuration changes, click Create Cloud Patching Configuration. The new configuration is added to the list.
The following settings are available:
